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

The connect of the FLL VFO is on my Bitx  Q6 Emitter  ( no Transitor) to Condensor Basis of Q7.

for CW i put a Resistor wit…

The aim has been achieved quite satisfactorily as close to one thousand Bitx Pcb and Kits have been shipped to members from this site and my Ebay shop.

I do agree my site is a bit difficult to navigate and at times confusing.There are many reasons for this. First of all I am not a good website developer, hi hi.    Secondly many kits I introduced found a way on cqbitx blog, because most of the kits are add one for Bitx, but some kits are quite different from the Bitx, like the Bingo or Avala.   But most of my old customers do know that I sell all these also.
