I find myself switching between Data A and AFSK-A quite a bit.
The RTTY dual passband DSP filter (DUAL PB) can help a lot with
QRM from nearby RTTY signals, and it eliminates much of the
off-frequency noise. You can also turn on TEXT DEC to get the K3
to decode the RTTY, giving you another chance with weak signals.
With cocoaModem I am always using the RTTY, rather than the
Wideband RTTY or Dual RTTY options. The crossed loop tuning aid
can't be beat. It simulates the CRT based tuning indicators used
with hardware RTTY receivers.

With PSK31 and the JT-modes, I've always had the K3 in DATA-A
setting. RTTY "seems" to work in either DATA-A or AFSK-A. Fred
Cady's K3 book states that AFSK-A is "optimized for RTTY". How?
What is the real benefit to switching to AFSK-A mode for RTTY?
Is that what everyone is using, or is DATA-A just as good?
