Portsdown – 8 band decode PIC

This is the pre-programmed PIC to control the custom designed 8 band decode board for the Portsdown transmitter.

The 8-band decoder is designed to work with the 8-band RF output switch and the “Portsdown 2018” software.  It is NOT required for the port 4 switch and band decoder.

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.

Note this is for the programmed PIC ONLY

If you have your own PICs, the code to program them is available on GitHub: https://github.com/BritishAmateurTelevi … and-Decode.
