Thanks for continuing to come up with ideas on making heavy metal RTTY
easier. As mentioned earlier, I do have continuous 2125 Hz (10 minute
file) at https://w6iwi.org/rtty/audio/ . I'll add files for other tones
(including 850 Hz shift).

My normal process in tuning up a terminal unit is to get the transmit side
working first with the AFSK frequencies set precisely (and Visual Analyzer
at https://www.sillanumsoft.org/ includes a frequency counter). I then
send the transmit audio into the demodulator and tune the demodulator
filters.

Again, THANKS!
