- Original Message - From: Roger J. Buffington [EMAIL PROTECTED] As the band conditions start to improve, with more signals on the band (remember, we are presently right at the solar minimum) using the narrow filters on digital modes will become more and more important. It will be

Roger- thanks for an excellent set of comments. With my rig (FT-920), my best filtering is in the audio, which limits me. I do have a narrower (INRAD) filter than the stock one and that helps. I can dream about a tuneable RF filter, though, can't I? Thanks- Bill-W4BSG At 05:37 AM 10/1/2007,

So which is better, park the dial and move the audio center frequency (ACF) ldquo;markerrdquo;, or park the marker and move the frequency dial? The former seems to be the standard method used for PSK31 (when using programs like Digipan and PSK31), but the latter seems to make more sense in the

Hey group, this is Frank K2NCC, Just wanted to ask what is surely a noobie question or two. If my waterfall (using MixW) can receive a signal between 300KHz and 3000KHz on the spectrum, that's my bandwidth of the radio, right? Seems to match what the manual says, 2700. I've read where PSK31 is
