Description
This is the blank PCB to build the custom designed 8 band decode board for the Portsdown transmitter.
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.
Note this is for the blank PCB ONLY and 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.
