Well, I took Stan's comment to mean they used the BFO for LSB to also serve
for RTTY without allowing a different offset. That being said, a later
direct comment from him said he had forgotten about the ability of the
Paragon to enter TTY mode by pressing SHIFT then CW, so he may have been
thinking about something else. I don't think there is a difference
otherwise.

Hi all,
I am curious about this statement:

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?
