I came across a DX station running psk31 split. He would say "CQ CQ from xxxxx up up up"
I tried calling back to him a few times by transmitting by moving up 60 to 1000 Hz on my waterfall... always finding a clear spot first, of course.
Anyhow, I wasn't successful at making contact. I'm curious if I was calling in the right spot. On SSB split operations, usually the split is 3 to 5 kHz if I'm not mistaken. Is this also the common split for PSK?
Any input would be greatly appreciated!
