I also have a TS-2000. Are you using the Packet filter menu, 50A? This can

I would really enjoy hearing some discussion on the use of OFDM on
HF. I work on an OFDM project and have an understanding of how it
works although I am not a system designer. I have also tried OFDM
with HamPal (digital SSTV) and WinDRM (digital voice) and it seems to
