Joost — Sat, 06 Feb 2010 17:39:21 +0000

I finally bought a networkdrive to be used in my home network. My wife was complaining that all pictures were on the pc downstairs (my shackcomputer) and she want to see them also on the pc in the living room. Time to share the data. But I needed a NAS style disk, not just some [...]

Designing and building a Manned Beacon or MEPT, part 1 of many

Joost — Sat, 06 Feb 2010 14:53:05 +0000

I came acros the site of IK0VVE with a wonderfull description of a MEPT. MEPT stands for Manned Experimental Propagation Transmitter and is usually very low power. He uses a crystal oscilator but I find them pretty expensive. So I Looked around the net for programmable oscillators. Those are even more expensive and in the most cases you [...]

Early March we were alerted by friends that there was a house for sale in their street. We know about 5 families in that [...]

Joost — Sat, 07 Feb 2009 08:19:28 +0000

This article is a reprint from my original article published in 2004. I don’t use the antenna anymore (collecting dust in the basement) but the article will stay here for informational purposes. I live in an appartment and don’t have the space to put up a large antenna for my Kenwood R1000 receiver. I knew the excistance [...]

That is about 6 Mhz above the 70cm amateur radio band. There are 8 channels starting at 446.00625 MHz and ending [...]

Avoid uncontrolled transmissions with this simple modification on your radio interface

Joost — Thu, 05 Feb 2009 19:20:50 +0000

Ham radio operators interested digital modes will often use these computer interfaces to automate CW contacts (send morse code from the PC), use the PC soundcard for RTTY and control push-to-talk functions among other things. Many of the PTT interface drawings found on the net suffer the same problem. Well it is not really a problem. Let’s have [...]

Joost — Thu, 22 Jan 2009 07:30:41 +0000

A friend of me asked if I could detect some WSPR signals on 20m. He has been monitoring it a while without any activity. I also read the comments of G4ILO on the WSPRnet.org site : http://wsprnet.org/drupal/node/384 I must admit that I was also stuck on 30m. He made a statement and yesterday I had a day off. [...]

Joost — Sun, 11 Jan 2009 13:27:57 +0000

On several sites you’ll find some html code showing the Aurora status, European and North American Eskip status. These images are created by the DX robot, maintained and ran by Allard Munters PE1NWL. You know what I mean if you can see it : Allard has spent a lot of time to create this tool but [...]
