Zero IF and Low IF modes

Postby Simon1 » Thu Nov 29, 2018 12:19 am

For ham hf band digimode use, under what conditions should i select to use which mode?

How far should the LO freq away from dial frequency? It said "some distance" on youtube.

How rsp1a internal tuner work? If i set a dial freq of 14MHz and LO at 15 MHz, the tuner is a superhet mixer, outputing 1MHz and 29MHz signal to the ADC, right? If LO is 13MHz, the ADC will see singal in "reverse freq order", as LO at 15MHz, right?
