Re: PSK31 split operation

George Weller KD9PCN

That's helpful gents. Thank you.  A pile-up is one thing and I can see the reasoning on that.  On wsjt-x, the rationale is that the Tx signal is narrow band; minor distortion (near the edge of the Tx passband filter) reduces likelihood of a decode, so wsjt-x sets the split and adjusts the audio offset so that the Tx is at the exact same frequency as Rx, but is now in the center of the Tx passband. It seems like the same logic would apply to any narrowband signal. Of course, as was pointed out, the PSK band is usually not crowded and you can pick a frequency in the middle.

I'll echo Stephen's sentiments.  I've seldom needed to use split for PSK because the PSK waterfall just isn't that crowded.

In Digital Master 780 it's pretty easy to set up split.  Just set up on a clear frequency and lock it, then move the receive cursor over to the station you want to work.  I usually center my TX frequency in the waterfall.
