I have a very nice 585 Paragon that I recently decided to run some RTTY
with. I am connecting with a Kantronics KAM to the Mark/Space jack on the
rear panel to run "true" FSK, and selecting RTTY (shift-CW) as the mode.
Everything is working well except I seem to need to offset the receive +200
Hz in order to receive stations I am working. This happened with 3 stations
in a row and, even though they were all using AFSK (sound card output to
their mic jacks), I believe I may have some problem here. I should note that
my Paragon is dead on frequency receiving USB and LSB. I can switch from AM
to either sideband with no change in tone listening to WWV, for example, and
never get a report that I am off frequency otherwise.
I looked to the need to perhaps adjust the RTTY BFO, but I see that C4 also
adjusts LSB receive, which is doing fine. Am I missing something here? Is it
just a factor of working "true" FSK vs. AFSK? Thanks.
