1. With the K3/K3S, FSK is *not* better than AFSK. In fact, before
firmware version 4.66 in March 2013, the K3's tranmitted signal in AFSK
was demonstrably cleaner than its signal in FSK. Now they are about equal.
2. If COM1 is a USB-to-serial adapter rather than a true serial port,
then you will need to use EXTFSK with MMTTY; standard single-port
USB-to-serial adapters cannot go slowly enough to do 45.45 baud RTTY.
3. There are either two (N1MM+ and MMTTY) or three (N1MM+, MMTTY and
EXTFSK) programs involved. Only one of them has direct access to COM1.
You should not have COM1 configured at all in N1MM Logger+. If COM1 is a
true serial port, MMTTY should be configured to use COM1 as its PTT &
FSK port. If COM1 is a USB-to-serial adapter, MMTTY should be configured
to use EXTFSK as its PTT & FSK port, and EXTFSK should be configured to
use COM1.
I think it would have been simpler to stick with AFSK.

This seems crazy to me.
I wish I could just go back to AFSK and my one cable setup. But now all my AFSK
