8-Band Decoder
This 8-band decoder is designed to work with the 8-band RF output switch and the "Portsdown 2018" software. It will provide switching signals (either always on, or PTT activated) to 4 Power Amplifiers and 4 transverters, and it also enables you to set which VCO filter should be switched in for the 4 transverter outputs. PCBs are on order and will be available from the BATC Shop.
The firmware for the 16F883 PIC is available here: https://github.com/davecrump/8-Band-Decode and will be moved to the BATC GitHub site once validated.
