Aha, therein (those two statements) might be the clue we sought :-).

You said you have not tried EXTFSK yet -- that means you are transmitting in AFSK!  Not FSK.

If so, reversing the polarity of the TS2000 FSK transmit setting will do nothing (unless you swap USB/LSB in data modes).

What you need to do is to go into MMTTY settings and reverse its transmit AFSK tones.

I don't run MMTTY (or any Windows program, actually), but someone else here can probably immediately point you to where to reverse the MMTTY AFSK tones.
