My backup Tentec rig is an OmniV. After my OmniVI returns from factory service and frees up the V, it (the OmniV) will be used for PSK31. I am absolutely inexperienced with PSK and would greatly appr
First, you probably shouldn't run more that 30 or 40 watts on PSK31, so you really don't need the fan. You don't need power with PSK31. I used an Omni V on PSK31 and (at least my Omni V) wasn't reall
if u want to alienate ur selfin the psk world run full out--u will not need fan on psk 25 or 30 watts is max or u are the only signal seen on waterfall--this really pisses off the rest of the troops-
Hi Allan Another tip: when setting up for PSK set output at 100 watts, then adjust soundcard so that PSK sig is 25-30 watts max on output meter. Make sure that you have computer sounds disabled, or u
Oh no. Never run FULL OUT in PSK. About 30 watts from a 100 watt radio is about right. Run the computer sound card, line input and line output direct to the line in and line out connectors on the Omn

A bit of an oversimplification. Two issues. #1 -- Power rating. PSK is a continuous mode, and most rigs must be "de-rated" by at least 3 dB (run at half their CW power) to avoid damage to the output
Sounds like the problem here is when someone reads, "Open the TX full" they think that means TX at full output. When I started in PSK I ran at a lower power level (15W on an ArgoV) but as I've been a

I hadn't thought of it as a "headroom" issue. The main point is that a PSK31 signal cannot tolerate any non-linear amplification. Actually, the intelligence still gets through, but the signal is badl

That is exactly right. It is the basis of my recommendations that 1) the sound card run so that the output level is at least 3 dB below clip, which reduces the distortion produced by the sound card;
