Not necessarily true. Are you using a "real" (motherboard or PCI/PCIe
card based) serial port or a USB to serial converter?
If you are using a USB to serial converter you will need EXTFSK if
the converter does not support slow data rates - unfortunately there
is no way (short of reading the manufacturers specifications for the
USB UART/BRIDGE used in the converter) to know if a given device will
work at low speeds. However, most *new* (currently manufactured)
converters do not work below 110 or 300 bps.

I haven't tried EXTFSK yet. But, I do have access to an oscilloscope.
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.
