Bitx Version 3C
For those of you wishing to build the Bitx 3 with ADE-1 Mixers the good news is that the PCB's are ready for the Bitx Version 3C. There have been no other changes in Bitx 3C
The Bitx3C has been tested and performance is good. I shall publish a video soon of a working set.
Published below are two pictures of Bitx3C.
The Bitx Version 3C PCB And kit will be available by next week onwards.

Bitx3B VFO complete band coverage with zero drift
A new video of Bitx3B is being shown here, which has the following improvement:
1. Full coverage of 20Mt band from 14.000MHZ to 14.350MHZ
2. Zero drift with varicap tuning diode.
The varicap is 1SV149 . They work up to a maximum of 10V biasing and capable of a C max of 500pF at 1V bias. so we can manage from 8V regulator easily.
This device was suggested to me by my good friend MVS Sarma from Hyderabad. India.
After trying this device i did not think twice by replacing it with MV209.
So now we have a very stable VFO with BITX3B giving a complete band coverage, who wants a DDS anyway for a mono band tcvr ........

Missing ground track in exciter, band pass filter stage.
Kindly correct the band pass filter stage in the Bitx3B pcb which has a missing track that should be connected between 39PF and ground for L1 and L2
