Re: Those of us members in the HALF Century (or more) Wireless Association

Where is your RF TUNE setting at max? I'm guessing you have no band oscillator... Steve Wedge, W1ES/4 Time flies like an arrow.? Fruit flies like a banana. Sent with Proton Mail secure email.

Re: Those of us members in the HALF Century (or more) Wireless Association

Re: Those of us members in the HALF Century (or more) Wireless Association
My understanding was that the LSB on 40/80 thing was because certain radios had crystal filter IFs that were between 40M and 20M. I seem to remember folks using 9MHz or so. So the mixing was
