Firmware Sketches


BITX40 Official VU2ESE.

Allards Sketches.

V1 Code https://github.com/amunters/bitx40
Requires the fewest hardware mods, and leaves the BFO using the 12mhz crystal osillator.

V2 Code  https://github.com/amunters/bitx40-raduino-v2
Requires more mods, including one that drives the BFO from the si5351's clk.


Both branches are being actively developed.
The V2 code allows you to do more stuff, such as adjust the BFO frequency to better align with your crystal filter.
