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.

Hi all,
I am curious about this statement:
Interestingly, Stan at Ten Tec was reading the list and also replied moments
ago. He said that the Paragon can not receive true FSK and that using the
offset is a requirement.
I understand that "True FSK" transmit capability refers to either
frequency shift keying a single oscillator, or switching between two
oscillators in RF stages (such as BFO oscillators, or shifting the VFO)
as opposed to using audio tones into a SSB transmitter.
What is "True FSK" receive? Using a discriminator in the IF instead of
using audio tone detectors or an audio discriminator circuit? Or would
it be two detectors each with their own narrow IF filter? Is using an
audio tone demodulator NOT true FSK receiving?
