Radio Fm sudah menjadi bagian kehidupan kita. Karena melalui radiolah kitan mendapatkan informasi dan hiburan sehari-hari. Bila radio kita bermasalah maka kita berusaha untuk memperbaikinya.&amp;nbsp;&lt;script async=&quot;&quot; src=&quot;//pagead2.googlesyndication.com/pagead/js/adsbygoogle.js&quot;&gt;&lt;/script&gt;

&lt;/script&gt;&lt;br /&gt;
&lt;div&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div&gt;
Bagaimana kalau yang menjadi masalah itu adalah signal radio yang diterima sangat kecil ? Apa yang kita lakukan. Tentu kita berusaha untuk mendapatkan signal yang kuat. Salah satu caranya yaitu memasang boster pada radio kita.&amp;nbsp;&lt;/div&gt;
&lt;div&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div&gt;
Kita bisa rakit rangkaian boster . Skemanya lihat gambat !&lt;/div&gt;

&lt;/script&gt;&lt;br /&gt;
&lt;div&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div&gt;
Ini ada pcb &quot; hifi tuner dtk anti desis&quot;.&amp;nbsp;&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both; text-align: center;&quot;&gt;

&lt;div&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div&gt;
Kita juga bisa gunakan merk yg lain. Walau PCB untuk FM stereo tapi saya akan &amp;nbsp;membuat radio FM yang mono aja karena komponen beberapa aja. Jadi pcb yang terpakai seperti gambar berikut :&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both; text-align: center;&quot;&gt;
&lt;a href=&quot;https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEieGCNGcvN1-zzP4otpFOy569sG-aPkjoBaOt3Gi5Obg7oVR73VummyRL7v4d4qKHTrR5-l3LA9VSaTaHSzyGl4lIQOq7IxUAUQkv5HenHNC4cZMnmY0ILfvZbvrNRmr2hZTF9Uox6Pefcl/s1600/20170405101128-1.jpg&quot; imageanchor=&quot;1&quot; style=&quot;margin-left: 1em; margin-right: 1em;&quot;&gt;&lt;img border=&quot;0&quot; height=&quot;320&quot; src=&quot;https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEieGCNGcvN1-zzP4otpFOy569sG-aPkjoBaOt3Gi5Obg7oVR73VummyRL7v4d4qKHTrR5-l3LA9VSaTaHSzyGl4lIQOq7IxUAUQkv5HenHNC4cZMnmY0ILfvZbvrNRmr2hZTF9Uox6Pefcl/s320/20170405101128-1.jpg&quot; width=&quot;289&quot; /&gt;&lt;/a&gt;&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both; text-align: center;&quot;&gt;
Itu kelihatan jelas komponen apa saja yang diperlukan untuk membuat tuner FM DTK Mono.&amp;nbsp;&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both; text-align: center;&quot;&gt;
Siapkan komponen tersebut dan tak lupa solder dan timah.&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both; text-align: center;&quot;&gt;
Sekarang tempatkan semua komponen ke lubang PCB sesuai gambar di PCB tsb !&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both; text-align: center;&quot;&gt;
Sudah periksa dengan benar kaki komponen terpasang seperti pada gambar&amp;nbsp;&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both; text-align: center;&quot;&gt;
&lt;a href=&quot;https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEilfSeD_m6CZaPQkoP6KLMK6mwTB1l2umSwufjkNxQhhP24O_rMavfD6WgLCRfzvylyrGVJ-Ohb-S6skFnfymKq0N4jW0Vfo3OzURzoV0M7byE80S4Ae0EzHzhKev5w07huT-TeVkUoW9KM/s1600/20170405101449-1.jpg&quot; imageanchor=&quot;1&quot; style=&quot;margin-left: 1em; margin-right: 1em;&quot;&gt;&lt;img border=&quot;0&quot; height=&quot;197&quot; src=&quot;https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEilfSeD_m6CZaPQkoP6KLMK6mwTB1l2umSwufjkNxQhhP24O_rMavfD6WgLCRfzvylyrGVJ-Ohb-S6skFnfymKq0N4jW0Vfo3OzURzoV0M7byE80S4Ae0EzHzhKev5w07huT-TeVkUoW9KM/s320/20170405101449-1.jpg&quot; width=&quot;320&quot; /&gt;&lt;/a&gt;&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both; text-align: center;&quot;&gt;
Maka siapkan solder yang panas dan timah kemudian balik PCB tsb dan PCB beserta komponen siap disolder.&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both; text-align: center;&quot;&gt;
&lt;a href=&quot;https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiPMIFJ6rnhi8c18jxH1mrtytOjxAKPqArX_nZTDD92QBFCYMVWjhIoTRyCiG7zQQJ6wwx5WSGNw1si2bRcZl1ftH6qWIy2RZ8unFmAhyphenhyphen8rYW2fw5zGMNfHZCDBDOTZToGsxql6C_xSamHW/s1600/20170405101546-1.jpg&quot; imageanchor=&quot;1&quot; style=&quot;margin-left: 1em; margin-right: 1em;&quot;&gt;&lt;img border=&quot;0&quot; height=&quot;176&quot; src=&quot;https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiPMIFJ6rnhi8c18jxH1mrtytOjxAKPqArX_nZTDD92QBFCYMVWjhIoTRyCiG7zQQJ6wwx5WSGNw1si2bRcZl1ftH6qWIy2RZ8unFmAhyphenhyphen8rYW2fw5zGMNfHZCDBDOTZToGsxql6C_xSamHW/s320/20170405101546-1.jpg&quot; width=&quot;320&quot; /&gt;&lt;/a&gt;&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both; text-align: center;&quot;&gt;
Solder dengan rapi mulailah dengan komponen yang relatif lebih tahan panas trafo if, resistor , kondensator dan terakhir ICnya. Lalu potong kaki komponen dengan catut serapi mungkin.&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both; text-align: center;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both; text-align: center;&quot;&gt;
Hampir jadilah tuner kita, tinggal solder kabel penghubung tuner blok sesuai terminalnya kabel tegangan , out put ( disolder di kaki positif elko c7, lihat digambar diatasnya !) , ground, if dan antena.&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both; text-align: center;&quot;&gt;
Tuner FM DTK Mono dah beres tinggal sambung out put DTK ke inputnya amplifier tak lupa kabel positif ke power suply 12 volt yang stabil.&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both; text-align: center;&quot;&gt;
Hasil tes dengan kabel antena sekitar 10 cm bisa menangkap sinyal radio jarak lebih dari 20 km. Kalau ingin menyetel kepekaan tinggal putar trafo ifnya ( lihat gambar di atas ! ).&amp;nbsp;&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both; text-align: center;&quot;&gt;
Bisa dilihat Vidio ya di you tube di link ini&amp;nbsp;http://adf.ly/1m4kts&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both; text-align: center;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;/div&gt;

Kali ini saya ingin share rakitan pemancar stereo dengan transiator final c1946.
Rangkaian ini menggunakan transistor c930 dua buah kemudian c1946 didorong Oleh c1970. Saya berharap keluar daya 30 watt. 

Hasil rakitan boster terlihat di gambar berikut :

&amp;nbsp;Sebagai osilator pemancar ini menggunakan MP3 wireles stereo seperti terlihat gambar di atas. Hasil stereonya cukup bagus didengarkan dengan radio merk politron. 
Namun pemancar ini tidak bisa digunakan cuap-cuap karena tidak ada jack input, hanya untuk memancarkan musik MP3 melalui plasdisk sebagai penyimpan file musik

Setelah dirakit nampak seperti gambar berikut. Pemancar belum dimasukkan dalam kotak.

Gambar diatas adalah transmiter fm mono rakitan yang saya buat dengan menggunakan osilator dari tuner blok seperti postingan yang  lalu. Dan transistor final menggunakan C1970. Untuk driver menggunakan transistor C930 dua buah dan komponen pendukung lainnya. 
Dan ouput tx  ini sekitar 1 watt.&lt;/span&gt;&lt;/td&gt;&lt;/tr&gt;
&lt;/tbody&gt;&lt;/table&gt;

Transmiter Fm saya ingin membuat pemancar fm daya kecil keluaran daya sekitar 0,5 watt.&lt;br /&gt;
Adapun transistor menggunakan yaitu c9018, c2026 dan terakhir C2053 dan beberapa komponen pendukung lainnya.&lt;br /&gt;
Dan sebagai osilatornya menggunakan tuner blok fm .&lt;br /&gt;
Setelah saya mencari komponen &amp;nbsp;di toko elektronik maka terkumpulah komponen yang dibutuhkan.&lt;br /&gt;
&lt;br /&gt;
Ini gambar tuner blok yang akan saya gunakan sebagai osilatornya.&lt;br /&gt;

&lt;span style=&quot;font-size: large;&quot;&gt;MP3 car&lt;/span&gt;&lt;span style=&quot;font-size: small;&quot;&gt; &lt;b&gt;is an electronic device that can read files of music or songs stored in the buffer flasdisk heard through a stereo FM radio, especially used in the car. You can also include audio from a computer, tape and others.&amp;nbsp;&lt;/b&gt;&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-size: small;&quot;&gt;&lt;b&gt;&lt;br /&gt;
&lt;/b&gt;&lt;/span&gt;&lt;span style=&quot;font-size: small;&quot;&gt;&lt;b&gt; &lt;/b&gt;&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-size: small;&quot;&gt;&lt;b&gt;The voltage used is a voltage of 12-24 volts found in a car that is in turn plugs the cigarette. Operation and settings in addition to existing orders in mp3 car also can use the remote control, making it very simple use.&lt;/b&gt;&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-size: small;&quot;&gt;&lt;b&gt;Radiance range is 4-5 meters with existing stereo pll.&lt;/b&gt;&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-size: small;&quot;&gt;&lt;b&gt;&lt;br /&gt;
&lt;/b&gt;&lt;/span&gt;&lt;span style=&quot;font-size: small;&quot;&gt;&lt;b&gt; &lt;/b&gt;&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-size: small;&quot;&gt;&lt;b&gt;And also good when used for broadcast in the house and if necessary strengthened by using rf amflifier radiance.&lt;/b&gt;&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-size: small;&quot;&gt;&lt;b&gt;&lt;br /&gt;

The output power is about 1.3W and the input driving power is 30-50mW. It will still get your RF signal quit far and I advice you to use a good 50 ohm resistor as dummy load. To tune this amplifier you can either use a power meter/wattmeter, SWR unit or you can do using a &lt;a href=&quot;http://rftransmitter.blogspot.com/2009/11/simple-rf-field-meter.html&quot; title=&quot;RF field meter&quot;&gt;RF field meter&lt;/a&gt;.&lt;/span&gt;&lt;/div&gt;&lt;br /&gt;

&lt;/div&gt;&lt;div class=&quot;MsoNormal&quot;&gt;The above FM transmitter design is a result of many hours of testing and tweaking. The goal was simple; to test many existing BA1404 transmitter designs, compare their performance, identify weaknesses and come up with a new BA1404 transmitter design that improves sound quality, has very good frequency stability, maximizes transmitter&#39;s range, and is fairly simple for everyone to build. We are happy to announce that this goal and expectations have been met and even exceeded.&lt;/div&gt;&lt;div class=&quot;MsoNormal&quot;&gt;&lt;br /&gt;
&lt;/div&gt;&lt;div class=&quot;MsoNormal&quot;&gt;The transmitter can work from a single 1.5V cell battery and provide excellent crystal clear stereo sound. It can also be supplied from two 1.5V battery cells to provide the maximum range.&lt;/div&gt;&lt;div class=&quot;MsoNormal&quot;&gt;&lt;br /&gt;
