I am working with several quite low-gain receiving antennas (K9AY loops and BOGs). I think I can use some additional gain, but am debating whether the preamp really has to be at the antenna end of my

My take on this has always been, if the atmospheric noise can be heard in the radio, above the inherent radio noise ( with no antenna connected ) then you don't need a preamp. The preamp will amplify

Good suggestion, I'll look into it. However, let me clarify that lack of AGC does not prevent armchair copy of weak signals. The problem with lack of AGC is that a strong signal blows your eardrums o
