[TenTec] Paragon on RTTY

[Ken Brown]

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?
