[RTTY] PSK and waterfall

[John - AI4FR]

Toss in the manual notch filter as well to take out a few more Hz or that strong near by station. Also, the IF shift can be a great help in some rigs to employ.

Well, another problem with PSK is that many PSK users are not avid 
DXers, just rag-chewers, and they don't know how to make a QSO in a 
pile-up. They will at least give the DXpedition their name & QTH, and 
sometimes continue with equipment, license year and other macros !

Otherwise, a PSK pile-up nicely spread must give better chance to QRPs 
than a RTTY one where only the strong can survive. Even better (faster) 
in PSK63.

Here, i sometimes "wide-receive" the PSK frequency in order to see who's 
on the air, but as soon as i know who i'm gonna talk to, i center his 
signal in the passband (Winwarbler does it for me) then put the 250Hz 
narrow filter (narrowest available in my 950).
