That Time Of Year Again

2012-10-28T18:13:00.000-07:00

Meaning the CQ WW DX Contest,and for once the Gods favored us with decent propagation,well on 10 meters at least cause that's all I have here LOL.
Right from the get go things were buzzing on 10,loads of big signals and of course tremendous QRM,but in so saying it was great to hear the band alive again.I did not make a serious effort here,cause as you all know I'm antenna challenged here,living as I do in a 3rd floor Apartment,I do fortunately have a deck that I can put up an antenna of sorts,all be it in a fixed location.At present it consists of a 2 element wire yagi for 10 meters in a U configuration.I must say though it works like a charm and matches pretty much the whole 10 meter band pretty flat swr in the SSB portion rising slightly at band edges but workable without a tuner over the whole band.Of course running QRP helps in that respect (5 watts).
As I said I dabbled a bit during the contest and thoroughly enjoyed myself,I didn't work a lot of stations (about 50) in all but made some reasonably good DX with my QRP.In all I worked 25 countries with the best dx being New Zealand (ZM4T for a distance of 8,217 miles not bad for 5 watts and a wire yagi. Also had a couple of Japanese stations, lots of Europeans various Islands and Equador HC1HC at 6,394 miles .
It was the first contest I'd participated in from this side of the pond and as I said I had a blast .My thanks to all the stations that had the patience to work my QRP station I hope they all had a great contest.

73's for now

Second Hand Ham Radio

2012-10-10T21:40:00.001-07:00

Hi again,
How many of you can remember when Ham Radio was a really friendly & social hobby,when you heard of a new guy in the neighborhood who was a Ham you popped over and said Hi and offered a hand in welcome and maybe even help install the station.How things have changed,the welcome mat is alas no more or at best rarely seen anymore.Remember going to Hamfests where you could be sure the items you bought were working ok when you got them home and if there was a problem you called the seller and it got sorted out.Plus things were cheaper second hand,look at ebay these days and you would wonder,things like an old FT101 going for $500 plus Heathkit qrp rigs fetching $200 ridiculous prices and strangely enough more fools ready to part with their cash to buy them.I laughed so hard the other night when I came across a glorified CB radio Base Station converted to ten meters with a $400 price tag, come on people get real ,how about some realistic pricing for a change ,not this " let's see how much money I can screw out of people " for this 40 year old Radio .I look at this kinda thing and honestly I just despair,money these days seems to be the be all and end all of everything. If I were to add up the current value of my radio gear here it wouldn't amass to more than $250 all in, and you know what ?. It works just fine.

Rant over !!!!!!!

10 Meters Springs to Life

2012-09-30T22:45:00.001-07:00

As in the previous post 10 Meters this weekend has been to say the least fantastic,here in Minnesota 10 meters is normally pretty quiet but this weekend it was hard at times to find a clear frequency to call CQ. Stations were booming in from all over, Europe,South America, Mexico,Japan,Greenland, Cayman Is, Puerto Rico ,Cuba,Canary Is, North Africa,with stations from the East Coast USA, West Coast USA & Canada all heard from this location on Sunday alone.Pile ups were the order of the day and many were heard here. Not having the power or the antenna to break them I mainly listened to the traffic.But I did manage a few QSO's with my 5 watts. I had YT1HA, S52NR,IZ5EBL & IZ5HPQ all on SSB.Not staggering DX I know but it keeps me happy just working a few here and there.
I got a surprise via E-QSL yesterday too,I received my first SWL report for my USA Call from a n SWL ( DL-1213867 Peter from Eulenbis in Germany ) I really appreciated that and immediately confirmed it for him.

Well as I said the weekend was totally enjoyable DX wise and I hope this bodes well for this winter,and the DX continues.

Till next time 73's gd DX

Hi All,
Been a good week here for us 10 meter operators,the band has been open nearly every day,offering good propagation into Europe in the early morning and running into the evening with good South American propagation.Even some Japan & Australia have been heard at this location,that's pretty amazing considering the antenna here is only a 10 meter wire loop strung up on our balcony.

All the stations above were worked from here using only 5 watts and the 10 meter loop.Good to see 10 meters open again and we hope it continues during the Winter months.When the band is open you can find me around 28.420 on SSB if you hear me feel free to call I'd appreciate the contact.

Magnum 257 RF Limited

2012-09-15T07:41:00.001-07:00

Hi All

I Just recently took possession of a Magnum 257 (non High Power) by Rf Limited and having read a lot of reviews about this transceiver I was eager to try it for myself. The radio was not new only new to me but well looked after second hand.It's one of the older versions brought out in 1999 and therefore only has the reset pads and 2 conversion points as opposed to the new versions that have a reset button and 4 conversion points. This small difference does not however take away from the performance of this little radio.

Out of the box the radio covers 10 meters only from 28.000 to 29.699 AM/FM/SSB a little let down that it didn't have CW facility but that's a minor issue. To expand the radio's coverage is a breeze open the rig find the reset board move the jumper from one position to another ans with power off (off course) short out the reset pads momentarily. Put the covers on and power up the Radio,as usual it powers up on 29.300 (the Japansese FM calling channel) why I don't know as over here it's 29.600 mhz. Press function button and hold,then press call button for approx 3 seconds and wallah you now cover from 25.165 to 29.699 .

I use it as a base unit hooked up to my 10 meter loop antenna on my balcony (3rd floor apartment) and it works pretty well indeed.This model (or mine anyway) is conservatively tuned to deliver approx 28 watts SSB / FM & 15 watts on AM this suits me just fine as I'm a keen QRP operator anyway.The receiver is pretty hot but a tad noisy radio really benefits from an external speaker something a little more widebanded frequency response wise than the built in speaker.On the CB part of things it can suffer a little from strong signal overload (backing off the RF gain here helps a little) but on the 10 Meter side this is not as noticeable.

Ease of use (well I found my way around it) in about 3 mins flat without reading the manual,so yes it's pretty user friendly.I found it hearing weak signals pretty well and it picked up 10 meter beacons better than my FT301d did. I worked a few PY stations on it yesterday and it performed flawlessy .

In my humble opinion it's better than the HTX 10 from Radio Shack (I've used both) so if you can pick one up for under $150 grab one they really are a nice little rig to have around.

QSL Designs

The final courtesy of every QSO is a QSL so they say,in my opinion it's always nice to receive a card from a fellow Ham ,these days though it could be either an actual real card or possibly an electronic one sent via e-mail or one of the QSL services like E-QSL etc.

Cards these days are much easier to fabricate,in days gone by a Ham used to have to design his card and then take it to a Printing Shop and have it manufactured for him.Often this was a very expensive venture especially if you required full color printing.Nowadays though with the advent of the home computer making and printing your own cards could not be easier.No need to make them 1000 cards in advance anymore just produce what you need when you need it.Plus you can change the design foe every card if you so wish,making each one a unique reminder of that particular QSO thus making them more collectable as well.You are limited only by your imagination so off you go start creating.!!!!!

Morse Code

2012-05-14T02:35:00.005-07:00

As I mentioned in earlier posts,apart from QRP operating my other love in Amateur Radio is CW or Morse Code.

International Morse code today is most popular among amateur radio operators, where it is used as the pattern to key a transmitter on and off in the radio communications mode commonly referred to as "continuous wave" or "CW" to distinguish it from spark transmissions, not because the transmission was continuous. Other keying methods are available in radio telegraphy, such as frequency shift keying.
The original amateur radio operators used Morse code exclusively, since voice-capable radio transmitters did not become commonly available until around 1920. Until 2003 the International Telecommunication Union mandated Morse code proficiency as part of the amateur radio licensing procedure worldwide. However, the World Radiocommunication Conference of 2003 made the Morse code requirement for amateur radio licensing optional.[13] Many countries subsequently removed the Morse requirement from their licence requirements.[14]
Until 1991 a demonstration of the ability to send and receive Morse code at five words per minute (WPM) was required to receive an amateur radio license for use in the United States from the Federal Communications Commission. Demonstration of this ability was still required for the privilege to use the HF bands. Until 2000 proficiency at the 20 WPM level was required to receive the highest level of amateur license (Amateur Extra Class); effective April 15, 2000, the FCC reduced the Extra Class requirement to five WPM.[15] Finally, effective on February 23, 2007 the FCC eliminated the Morse code proficiency requirements from all amateur radio licenses.
While voice and data transmissions are limited to specific amateur radio bands under U.S. rules, Morse code is permitted on all amateur bands — LF, MF, HF, UHF, and VHF, with one notable exception being the 60 meter band in North America. In some countries, certain portions of the amateur radio bands are reserved for transmission of Morse code signals only.
The relatively limited speed at which Morse code can be sent led to the development of an extensive number of abbreviations to speed communication. These include prosigns, Q codes, and a set of Morse code abbreviations for typical message components. For example, CQ is broadcast to be interpreted as "seek you" (I'd like to converse with anyone who can hear my signal). OM (old man), YL (young lady) and XYL ("ex YL" - wife) are common abbreviations. YL or OM is used by an operator when referring to the other operator, XYL or OM is used by an operator when referring to his or her spouse. This use of abbreviations for common terms permits conversation even when the operators speak different languages.
Although the traditional telegraph key (straight key) is still used by some amateurs, the use of mechanical semi-automatic keyers (known as "bugs") and of fully automatic electronic keyers is prevalent today. Software is also frequently employed to produce and decode Morse code radio signals

CW is not just another mode like SSB, FM, PSK-31, etc.
It is a unique mode that has alot of advantages. Consider the following.............

1. It a Universal Language

No matter who you are talking to in the world, you can complete a contact on CW. You cant say that about any other mode. Take for example, SSB. How can you talk to someone who does not understand a word of English? For example, what about a five and nine signal report? There are as many variations of "five and nine" as there are languages. Unless you and the other station can understand the numbers of a common language, you are at a full stop. On CW, you can send "599". Regardless of what language the other station understands, "599" means the same in every language when sent by CW.
While the example that I have used above is about signal reports, it holds true for other parts of the QSO as well. Some countries use different phonetics so even getting your callsign can be a problem. On CW, no problem.
CW really is a Universal Language.

2. It needs very simple equipment.

There are plenty parts of the world where the cost of a commercial rig is prohibitive. The most simple transmitter to build is a CW transmitter. All you have to do is to generate a carrier and to turn it on and off. What could be more easy!!! As a result, you will find stations on CW that you will never hear on any other mode. This is especially important if you are after DX.

3. Chasing DX.

Well if you into chasing DX on the HF/VHF bands, then you really do need to use CW if you want to work all the good DX on the bands. Needless to say, you will work plenty on SSB. But, there are times when the DX station will only operate on CW or is so weak, that you can only work them on CW.

4. Signal to Noise Ratio

As you well know, if you ever listen to a weak signal, it is only a matter of time before QSB (fading) will take the signal down into the noise. On SSB, once the signal goes beyond a certain point, then thats it, you have no idea what the other station is saying. On CW, it really is amazing how far into the noise a signal can go and you can still copy it. The same of course holds true for signals that are very weak to start with. On SSB, you may know that someone is there but you cant make it out. On CW, you can complete the contact. In fact, a CW signal can have more than a 10 dB advantage over a SSB signal.
What does this mean?
Consider the following situation. You can just about work a CW station in the noise with 100 watts. The DX station is running 100 watts as well. To have a weak SSB contact, you would both have to run over a 1 Kilowatt each!! Now, thats some advantage.

5. EMC / RFI Problems (ie. Radio, Telephone and TV Interference)

We live in a world where there are more and more consumer items like TV's, HI-FI's, Radios, Computers, etc appearing in households. Many of these items behave very poorly in strong RF fields. This is probably one area that effects most radio amateurs to some degree. For some, it will mean that they cannot operate at all.
For example, on a telephone, an interfering SSB signal can sound like a garbled voice. With CW with the same power level, you will hear a slight clicking sound. ie. For the same power level, CW will cause less interference than SSB. Now consider the fact that you can also get alot of contacts by running lower power on CW and you can see that it can be an obvious solution to alot of interference problems.

6. Bandwidth

An SSB signal will usually occupy about 2.5 KHz. An FM signal will take up about 10 KHz. A CW QSO can take place in a bandwidth of about 300 Hz. As a result, you can fit alot more QSO's into a given bandwidth with CW. This is especially important on some of the HF bands like 40 metres where there is only 60 KHz available for SSB contacts.
In addition, because you are only listening to a single tone in a narow bandwidth, it is alot easier to filter out QRM (Interference).

7. Smaller Antenna's

As alot of Radio Amateurs in urban areas know, it can be very difficult to put up any decent size of antenna. With all the recent bad publicity that MMDS and Mobile Phone masts have got, alot of people are paranoid about any type of antenna in their neighbourhood. As a result, for alot of radio amateurs, the most they can get up is a simple wire antenna or an indoor antenna. Running 100 watts on SSB in a urban area can cause alot of problems. Again, the solution is CW. Less interference and the ability to use lower power. CW can make the difference between getting on the air and operating or not getting on the air at all.

SO YOU WANT TO LEARN MORSE CODE

Forget Frustration: Gain Valuable Morse Skills
And Increase Your Amateur-Radio Pleasure

By David G. Finley, N1IRZ
Copyright © 1995, 2000. All Rights Reserved*

Note: For complete information on Morse Code training, CW operating, Morse Code history, and more, see the author's book, Morse Code: Breaking the Barrier, published by MFJ Enterprises, Inc..

Amateur license restructuring is here. You no longer need to pass a 13- or 20-word-per-minute (wpm) test to gain full operating privileges. Passing a 5-wpm test gets you everything. However, there are good reasons why you should do more than that. Having a level of Morse proficiency that is of real use on the air, meaning that you can copy at 12-13 wpm or more, will add immeasurably to your enjoyment of Amateur Radio.

Such rewarding HF activities as DXing, contesting and QRP operating still rely heavily on CW. Thousands of hams enjoy CW for its own appeal as a relaxing mode different from most other means of communication. And even on VHF and higher frequencies, you'll find that exciting activities such as Moonbounce and weak-signal work still require Morse skills for full participation.

The pressure to reduce the code-speed requirements came from the widespread perception that getting to 13 or 20 wpm is a nearly imsurmountable barrier. That perception is wrong. For little more investment of time than it takes to pass the 5-wpm test, you can gain real, higher-speed code proficiency that will enhance your enjoyment of the hobby.

Most of what you've been told about learning Morse Code is wrong -- dead wrong. Amateur radio operators traditionally have used the slowest, most frustrating, most painful and least effective techniques possible for gaining code proficiency.

You can gain real code proficiency. You can do it in a reasonable amount of time and with a minimum of frustration and pain. In order to do so, you must approach code training from a different perspective and use different techniques from those common among amateurs for the past half century.

It will require work (just as it does to get to 5 wpm). You will have to commit yourself to at least one 15-30 minute training session every day until you reach your goal. You may succeed in a month or in several months; individuals differ greatly. Without this committment, however, you may as well not bother.

So what's new here? By using a code training method devised by the German psychologist Ludwig Koch some 60 years ago, you will progress as quickly as you possibly can, with ample reinforcement and little frustration. By understanding this method and how it builds your code proficiency, you will know why you have to spend time practicing and you'll be able to make a reasonable prediction of how long the total effort will require.

We're going to start on your road to success by throwing some time-honored ham-radio traditions onto the trash heap where they belong. These are:

Slow (5 wpm) code -- It ought to be illegal to teach anyone code at 5 wpm. Every minute spent toying with 5 wpm code is irrevocably wasted. In addition, as we'll see later, starting with slow code is a virtually-guaranteed path to frustration and quitting. Morse at 5 wpm and Morse at 15 or 20 wpm are completely different critters, and you don't want to waste time on the wrong one.

Charts, mnemonics, musical cues and other "memory aids" -- These things make you think about what you're doing while trying to copy code. That is deadly to proficient copying.

Code tapes -- In very short order, and unconsciously, you'll memorize the tape. This will lull you into false confidence in your ability. That false confidence will be quickly shattered when you hear transmitted text that you haven't memorized.

Copying QSOs off the air -- You don't know the speed of code you find on the bands, and much code on the air is pretty badly sent. All this makes it useless for training purposes. Formal code-practice sessions, such as those on W1AW, are OK, however.

Now that you know what you're not going to do, let's start examining just how you can best gain code proficiency.

The Mechanics: Just what is code training, anyhow?

Go to the shack of a veteran CW operator, or visit the CW station at a club Field Day operation. Watch people copy and send code at 30 to 35 wpm. You'll notice they're pretty relaxed about it; they're not sweating each character as it comes out of the speaker and they're not racking their brains to "figure out" what's being sent. Code has become second nature to them.

That's the key to code proficiency. Copying code must be a thought-free process. When you hear a character, you should know, without thinking, what it is. It should be a reflex. In fact, copying above about 10 wpm can only be done by reflex. Above that speed, thought processes are too slow to succeed.

That's why slow code is a deadly trap, and why traditional amateur methods of code training are so painful and frustrating. Most hams are told to memorize all the characters, then start building their speed. When you do it this way, you build a "lookup table" in your brain, comparing each character you hear with those in the lookup table until you find a match. This process shuts down from overload at about 10 wpm. That's why people experience a "plateau" at 10 wpm, and don't see any progress for weeks or months.

Those who finally get over that "hump" and progress beyond 10 wpm do so because, through constant practice, they have begun to copy code by reflex instead of by thought. They are the lucky ones; this 10 wpm barrier is where many folks give up out of frustration.

Code training, then, should completely bypass the lookup-table phase and begin by building copying proficiency as a reflex. This was recognized in the 1930s by the German psychologist Ludwig Koch, who devised the most efficient method known for Morse training. It's his method, and how you can use it, that we're going to examine in detail.

Morse Training by the Koch Method

Koch's method is a simple, direct way of building reflexes. However, it requires either a computer and Morse software or a personal trainer. That's why it was overlooked for so many years. Now that computers are commonplace, it should become the standard Morse training method. Here's how it works:

You start out by setting up your computer (or a microprocessor-based code tutor machine) to send you Morse characters at 20 wpm and at an overall sending speed of at least 15 wpm. You then get out your paper and pencil and have the machine start sending -- but only two characters. That's right, for your first sessions, you'll only have two choices. Copy on paper for five minutes, then stop the machine and compare what you copied with what the machine sent. Count characters and calculate your percentage of correct copy.

If your score is 90 percent or better -- congratulations! You just learned your first two characters, and, importantly, you learned them at full speed. You'll never have to learn them over again. If you didn't make 90 percent, practice some more. As soon as you can copy the first two characters with 90 percent accuracy, add a third character to your practice. Your accuracy will drop as you work on assimilating the new character, but it will rise again to 90 percent or better. Then you add the fourth character, and so on.

This method does not allow you to build that lookup table in your brain. To copy at full speed, you must build the reflexes in order to achieve 90 percent accuracy. And that's what you're spending your time doing -- building reflexes. Think of it as a parallel to perfecting a tennis swing or mastering a gymnastic routine; you're practicing until you get it right. The Koch method of building code proficiency character-by-character is similar to standard methods of teaching touch typing, another skill that must be reflexive.

This is a very individual method of training -- you progress at your own best speed, and spend only the time required to gain each new character. This means that you will waste no time in reaching your goal.

How much time is required? That will depend on the individual. Koch himself, with hand-picked students, got a group to master 12 wpm code in a mere 13.5 hours. You probably won't match that, but that's much faster than any other method in the psychological literature. You can get an idea of how long it's going to take after you've mastered a few characters. Keep track of your training sessions (some software will do this for you) and calculate your hours-per-character rate (or characters-per-hour if you're really fast!). That, multiplied by the 43 characters in the amateur Morse test, will give a rough idea of how long it's going to take.

While the Koch method is the fastest method of Morse training, speed alone is not its principal advantage. Its principal advantage, and a major difference from other methods, is that it provides you with constant positive reinforcement. This begins with your realization, after mastering the first two characters, that you can copy code at 15 or 20 wpm, because you just did it. After that, each new character mastered is further proof of your progress. Contrast that to slowly trying to build speed up from 4 or 5 wpm, then hitting the plateau at 10 wpm and seeing no progress for a long time. With the Koch method, frustration is at a minimum.

Constant testing is necessary to ensure that you maximize the effectiveness of the Koch method. You must copy on paper, so you can grade yourself. Remember, if you score 90 percent accuracy or better, add another character. If you score any less than that, try again. By constantly testing yourself on continuous copying of at least five minutes, you know exactly how you're doing and exactly when you should add another character. This results in the fastest progress possible.

Naturally, with the Koch method, you'll be copying random groups of characters, rather than words, until you've mastered the entire character set. If your software allows, make these groups of random length, rather than a constant stream of five-character groups. This will ease the transition from random groups to actual words. Yes, there is a difference in the rhythm and "feel" of words and random groups. Once you've become accustomed to copying words, you should start copying sample QSOs, which are the format of the amateur tests. Pay special attention to callsigns, locations, and numerals; these are the types of things that can form questions on the test.

As you proceed toward your goal, remember that some days are just going to be better than others and some characters will take longer to assimilate than others. You know, however, that you can reach your goal because you've already mastered some characters and proven that copying at full speed is something you can do. Keep in mind that what you're doing is building reflexes, and that takes time. The amount of time you require has nothing to do with your intellegence; it's just how long it takes for characters to "sink in" and become part of your reflexes.

So there it is -- your path to real, useful Morse Code proficiency. After you've used this method, and start enjoying the wonderful world of HF radio, try a few CW QSOs. With Morse code developed as a reflex, you may just find that you really enjoy using it on the air. After all, you've gained proficiency without the frustrating ordeal that most hams have endured for decades. See you on the HF bands!

A Personal Note

These ideas may sound very bold and unconventional, but I know they work, because they worked for me.

I fell in love with radio in grade school, but was kept off the air for 30 years because I found traditional code training just too frustrating. During those decades, I tried several times to learn Morse, but every time gave up in frustration and disgust -- my progress was just too slow.

In 1991, I became one of the first 500 people to enter ham radio by way of the no-code Technician license. After becoming bored with repeaters and HTs, I decided to make one last attempt to master the code. Fortunately, I stumbled on information about Koch's method, and found that it was the only thing that would work for me. In 1993, after diligent work at my computer, I took my first code test and passed the 20 wpm exam on the first try.

I became very curious about why Koch's method had worked for me when all else had failed. That sent me to libraries to read the now-aging psychological literature about Morse training. I soon realized that the Koch method achieves its speed through directness; if you want to copy reflexively at 15 or 20 wpm, then just start building those reflexes from the start. I also realized that it provides much more positive feedback than any other method, so you can keep your motivation and a "can-do" attitude throughout your training.

This was knowledge I wanted to share with others, so I began giving lectures to amateur groups on the topic. I quickly found that, after my lectures, "old-timers" would come up and tell me that my ideas on the need for reflexes were absolutely right. Many said that the Koch method sounded similar to the intense code training they had received in military schools.

Probably the only reason Koch's method didn't become standard back in 1936 when he first published it was that the average individual had no way of implementing it. The personal computer has changed that, and the time has come for the Koch method to replace all others. I hope that the speed and positive-reinforcement aspects of the Koch method can cut down the code barrier to a much less formidable size.

Prior to the FCC's restructuring of amateur licensing, the percentage of U.S. hams who had passed at least a 13-wpm code test had long since become a minority and was dropping steadily. This "code barrier" was causing an unhealthy stagnation in the amateur ranks. Many readers of Morse Code: Breaking the Barrier wrote to tell me how the Koch Method had helped them overcome many years of frustration and upgrade their licenses. It was gratifying to hear of these success stories. Now, people can use the Koch Method, not because they have to pass a test, but because they want to increase their amateur-radio pleasure.

I cannot overemphasize my dislike -- even hatred -- for 5 wpm code. As I've outlined above, it is highly counterproductive to gaining proficiency at higher speeds. In order to go from 5 to 13 wpm, you have to start over again, even though you may not realize that while you're doing it. The worst aspect is that many people pass a 5-wpm test, then never go beyond that. Why waste your time learning a skill (slow code) that has no relevance to real (13+ wpm) code proficiency and is of almost no use on the air?

Finally, as I was using the Koch method and building my code skills, I intended to forget the code as soon as I passed the test. My 30 years of frustration had built up a bitterness about CW. However, about two weeks after getting my first HF rig on the air, I looked at my straight key and decided to try a CW QSO "just so I can say I did it." Guess what? I enjoyed it. My second CW QSO was with a DX station, and I was hooked. With the encouragement of a CW Elmer, I continued to enjoy the bottom parts of the bands, and now my microphone isn't even plugged into the rig!

If the Koch method could overcome three decades of bitterness and turn me into an enthusiastic CW operator, I think it's certainly worth a try on your part. Have a go at it. Maybe I'll find you on the CW bands and we can have a ragchew.

Best of luck, and 73.

QRP Operating

2012-05-12T23:38:00.002-07:00

As you may have noticed in a previous post I'm a big fan of QRP operating.What is QRP? Well QRP is the Amateur Q Code for low power operating usually 5 watts or less, less than 1watt of power is usually designated QRP/p.It's easy to work stations using the usual transceiver power of 100 watts, or more in some cases some stations add external linear amplifiers and run into the 1000's of watts this is commonly called working QRO (yes another Q code ).
In my opinion QRP is much more challenging and satisfying than running loads of power, but that's just my personal opinion and I don't knock those that enjoy working QRO that's their choice as QRP is mine.

As you see by the Certificate above I'm a member of the North American QRP CW Club a club that promotes my two favorite aspects of Ham Radio, QRP & CW (aka Morse Code) more information about them can be found on their website.

DOES QRP REALLY WORK?

According to Rich Arland, K7YHA (now K7SZ), in World Radio magazine (Feb. 1990, year 19, issue 89, pp. 46-47) the long-distance low power record is held by KL7YU and W7BVV using one micro-watt over a distance of 1,650 mile 10-meter path between Alaska and Oregon in 1970. This is the equivalent of 1.6 billion miles per watt.

Another fact to consider: NASA's deep space missions typically achieve mile-per-watt ratings of more than 500 million miles. One example was the 8-watt signal from Pioneer 10*. At a power level equal to that of a night light (or is that Knightlite?) the craft's signal traveled 6.8 billion miles (11 billion km) to earth for a rating of 850 million miles per watt, or about half of the KL7YU/W7BVV record.

* Launched March 2, 1972 from Cape Kennedy for a two-year mission to Jupiter. The probe is now more than twice the distance from the sun as Pluto, traveling at 28,000 mph in the general direction of the first magnitude star Aldebaran.

January 2, 2005 - New London, NC - Bill Tippett, W4ZV, of New London, NC correctly copied code word OMAHA (on CW) from the N2XE beacon transmitting with a peak carrier power of .0000406 watts at 3.5455 MHz on the 80 meter Amateur Radio band. Bill confirmed reception of the beacon at 2328Z, January 2, 2005. The precise distance between the two stations is 546.8 miles, establishing Bill's record reception distance at 13,467,980 miles per watt. Tippett used a Ten Tec Orion Transceiver with a 1000 foot Beverage antenna (named after Dr. Harold Beverage who invented it in the 1920s).

The N2XE beacon transmits from an Elecraft K1 (heavily attenuated) using an 80 meter off-center fed dipole, 45 feet AGL (above ground level). The beacon peak carrier output was measured using an Agilent 8563EC Spectrum Analyzer at 40.6 uW (40 millionths of a watt). The beacon transmits a unique code word each evening. Receiving stations are required to correctly copy the code word in their report. The word is published the following morning.

The N2XE Beacon Project was started in December, 2004 by (NAQCC member) Paul Stroud, AA4XX, Raleigh, NC and John Ceccherelli, N2XE, Wappingers Falls, NY with the goal of having a little fun and to go where no diminutive signal has gone before. Beacon times and frequencies are posted daily on the QRP-L reflector www.kkn.net/archives/html/QRP-L. Tests continued on 160, 80 and 40 meters through the end of February 2005.

One reason the NAQCC is a QRP CW club is because QRP and CW go together so well. CW takes up about 100Hz of spectrum whereas SSB uses about 2000Hz. The average power density for CW, given the above values, is 1 Watt/Hz and for SSB .05 Watts/Hz. So if we compare the two modes we could say that gain in using CW over SSB is Gain(dB)=10*log(1/.05) which is equal to 13dB What does this mean? It means that 5 Watts of CW is as efficient as 100 Watts of SSB. Just a little food for thought.

What is QRP? It is SKILL, NOT POWER, and yes, it really does work. Try it, you'll like it. Join the North American QRP CW Club - it's free - and our motto is: No dues, just DO!

Amateur Radio QRP Calling Frequencies

QRP is one of a set of quick-to-send symbols beginning with the letter Q, for Quick.

Originally QRP was sent in Morse Code to quickly communicate that a station was using Reduced Power. Over the many years since that time it has come to generally mean "very-low-power," rather than "reduced power." Of course, "reduced" and "very-low" are both relative descriptions. One person's concept of very-low-power may be relatively high-power to another. Even so, among Radio Amateurs, QRP now is generally understood to mean a CW transmitter with 5-watts or less RF power output or SSB transmitter with 10-watts or less RF peak-envelope-power output.

Thanks for reading the blog that's all for now ,more next time till then 73's es Good DX

Radio's here at KD0PNP

2012-05-12T00:08:00.002-07:00

The equipment used here at KD0PNP is all pretty old ,just like the operator.having just recently gained my USA ticket you'll appreciate that there is not a vast amount of equipment in use.

The main transceiver is by Yaesu an FT 301 D in association with an FP301 Power Supply & an FC 301 Antenna Tuner. The 301D is a full power 100 watt transceiver but in my case I have removed the Power Amplifier stage making it a QRP transceiver capable of running at maximum 10 watts PEP but used here mainly at 5 watts or less.The antennas are simple as well 2 dipoles one for 20 meters and one for 10 meters.

For 2 meters FM I use an Icom IC22a diode matrix 10 watt FM transceiver into a home built 3 Element Loop Fed Array vertically polarised.

The CW key is an old Speed X key . So as you see nothing very special here and honestly to enjoy Amateur Radio that's all you need it really does not need to be the lastest all singing all dancing Radio costing thousands of $'s to get you on the air and meeting new people.

Intro

2012-05-11T23:12:00.001-07:00

I started my Amateur Radio activity many years ago (1988)to be exact,in those days I was still living in the United Kingdom and holding a Class B Amateur Call of Gi7CNO,having come up the ranks from CB radio which in those days was very popular indeed .I owe a debt of gratitude to CB Radio for without it's influence I would probably never graduated to the realms of Amateur radio or never known the joys of working on CW .

Amateur Radio is indeed a worldwide hobby and one that has a following of millions of people of all walks of life in many many countries around the world.Through the medium of radio communication horizons are spanned and cultural differences set aside in genuine friendship and love for our common interest that is Amateur Radio.
