Thanks Don so it seems I was doing the right thing I did start with
MMVARI then went to MMTTY both AFSK A I misspoke in the original post
saying DATA-A but meant AFSK-A so it seems I am on the right track I
find tuning with the VFO and watching the markers on the P3 the
easiest I dont like tuning with the mouse.

David,
Actually, MMTTY and data sub-mode AFSK-A on the K3 will give you the
best transmitter IMD. With MMTTY, you would tune with the K3 VFO
rather than clicking on a waterfall display - this is a computer
soundcard application of MMTTY.
If you prefer to click on a waterfall display, then an application
other than MMTTY should be used.
Yes, you can do FSK-D with MMTTY, and that requires a "one transistor
interface" to drive the K3 ACC connector pin 1. Some prefer that
approach because it avoids setting the soundcard levels correctly for
transmit. The choice is yours to make.

I have dabbled a bit with RTTY mostly with the Centenial and some DX
but this past weekend I thought Ill give the CQWW-RTTY a try. spent
a little time and got things working using N1MM and MMVARI using
DATA-A relying on the P3 for waterfall display. It seems I got
bitten by the RTTY contest bug because I loved it. So here is the
question to the serious RTTY contester. what is the ideal setup.
is MMTTY and DATA-A best or should I interface for fsk. and is MMTTY
the best option here? and more important what is the best way to do
this both from software and hardware setup.
