I would like to adjust a CB radio and the transmit frequency a little bit using the spectrum analyzer (unless my FC proves to be accurate), what do I need to sample the transmit frequency? I am looking for something to go from the transmitter to a device (the bit I dont know) then out to a dummy load, I believe there is a device with a BNC take off that goes to the SA but I am completely unsure what you use or how you connect it. Sorry if this make no sense! I am wanting to adjust a CB whats the best way to do it with a SA and dummy load?
