K3 - FSK question

Hi, I'm new to the K3, (Aug 2010 sn 4536). I have really enjoyed it a
lot. I have dabbled into digital modes a bit and am wondering, how do
i connect and send/rec FSK?

I have determined that I need a cable from PC serial port to the
"accessory" connector and connect to gnd, PTT, and FSK. Do I still use
the soundcard to rec or does the radio have a line out that would
connect to the serial port RX pin?

Another question. Last night I was messing with PSK, and noticed that
in PSKD mode, the waterfall on Digipan showed a band of activity at
one area of the display, while in DATA A mode, it had shifted a lot to
the left, maybe 1khz. What gives?

Re: K3 - FSK question

What software were you planning to use, MMTTY or maybe DM780. I know
MMTTY supports "true FSK" as does the K3. Not sure about DM780. And
yes, both of the above use the sound card for receive. The K3 will
decode RTTY but the display is limited and as far as I know there is
no provision for a remote terminal, so I would go the sound card route.

On your third question, I am curious about that myself and awaiting an
answer from one of the gurus.

Bill,

I would suggest that you start by reviewing AA5AU's wonderful RTTY
tutorial here: http://www.aa5au.com/rtty.html

Most of your questions are RTTY-specific rather than being unique to the K3.

Re: K3 - FSK question

as this thread has expanded to include RTTY sites in general,
here are a couple of other links that may be helpful:
