This design is an upgrade from Bitx Version 3. The original Bitx design belongs to the author OM Farhan from India.
This new design was suggested by a few Italian Hams, we took the Basic design and added further mods.
The design made by Italian Hams did not have the Connections and buffer in VFO for the FLL Freq counter,or the anit hissing filter in the audio amplifier. nor the AGC module, which is mounted on back of a VU Meter. So we had to do a lot of testing after making several boards and testing them we finally made these boards.
The good news is that the Manual is being made by OM Leaonard , who has a great experience with the Bitx 3 and Bitx 20a
The Manual may take some time. The basic manual is same only with certain changes in the VFO, Audio and TX Pre amp. So we will presently provide with some head on start notes.
