Feedback By Radio Amateurs World Wide for Bitx Version 3 Kit

It has been a long time since I updated this blog,the reason being for new orders for Bitx Kits and other Kits.
The Bitx has reached many countries now. The usual countries are USA, and most parts of Europe.
The latest are a few Asian countries Thailand , Viet Nam Nepal and Argentina in South America.

It is really great to see the interest sustained in Bitx Version 3 and as new Hams build  it, then more get the desire to try it out.

This year the aim will be to get the modules for available for Bitx to be used as a multiband with CW and other modes, and a new case with kind suggestion from friends.

I have received some feedback which I  would like to share, as to show the quality of service and packing of kits from my end.

Father Christmas is spent in advance! Yesterday the package arrived sooner than I thought. I placed an order with Sunil VU3SUA December 4, but he warned me that the expedition soon as he had many orders. On 17 December he informed me that the package is gone. On December 23 it happens at home (and my wife hides the warm ...). Another surprise: no tax to pay although the Vietnamese Customs have opened the package and a few bags of components. I'm more impressed by the quality of service. Pack very well, and packaged components clearly identified. Even the wire for straps comes! Everything to make a beautiful mount. PCB silkscreen prints and good quality.

A good friend of mine Marc from France had some problem in getting his Bitx ,as due to some reasons  it returned back to me. I again sent him a Bitx Ver 3  kit again which he got this time. Presented a picture Marc holding the Bitx. Great Pic.

Keyer,Soundcard and AGC details for Bitx Version 3

DG1NPJ Juergen Pfeifer From Germany has sent us information for the AGC, CW Keyer and Soundcard details that he has incorporated in his Bitx Version 3. Here are the details so that it would help all members in constructing these mods for the Bitx.


Contents of Email from  DG1NPJ Juergen Pfeifer From Germany

Hi Sunil,
the CW Modul i have found by Google looking for schematics of Bitx20, it works, but the Audio Output is to small, i will  fix this bug in the next days.
the AGC schematic is from the Bitx Yahoo Group, the Soundcard Interface is a old schematic, it works on all my TRX in my shack. The Pic Keyer i have found on this webpage: http://freenet-homepage.de/dl4yhf/pic_key.html
For the AGC/Keyer and CW Modul i send you a PCB Layout, not the best but for me is good.

The connect of the FLL VFO is on my Bitx  Q6 Emitter  ( no Transitor) to Condensor Basis of Q7.
It works great wenn you make the coil L1 in VFO with 50 Turns (Frequency 14.065 to 14.350 MHz )
for CW i put a Resistor with 18 K from BB204 ( D1 and D2 ) with a switch to GND ( Frequency 14.000 to 14.075 MHz )parallel to R3  82K.
The same switch i use for CW Tone or PSK (from Soundcard Interface ) on Mike Input.

The S meter, the PCB is from you, is connectet in the AGC on R12 of 12 V side, it works but its only for viewing :-)
not a real meter !!

My PCB are made only with a Laser Printer on Paper and Transfering with a hot Iron on the Copper befor etching.
Cheap and Good , Look here:  http://thomaspfeifer.net/platinen_aetzen.htm
Ist only the same Name of this People its not my brother hi hi
