[TenTec] Paragon on RTTY

[Bwana Bob]

I use FSK with my Paragon and a Kantronics KAM. It works fine. To go to 
the RTTY mode, press SHIFT then CW. This should give the proper offsets. 
I run with the PBT centered with  all filters except the 1.8 kHz. If you 
need to offset the RIT or PBT, check the frequencies of the carrier/BFO 
oscillators. They can change with crystal and trimmer capacitor aging. I 
found that I had to shoot the trimmer caps with contact cleaner because 
some had become unstable. I had the same thing with my Icom R-71A.

With the Paragon, I can even copy RTTY with the .25 kHz filter.
