It is possible to tune for RASCAL by ear. I use the following steps:
1. Tune to find the frequency with the greatest s-meter reading
2. Listen to the tone part of the signal, not the raspy part, and aim
for a note much higher than a regular CW signal.
3. When the green sync light goes on in RASCAL, fine-tune to centre
the signal at 1600 Hz.
Does anyone know how narrow a SSB filter I can apply to this signal? I
have a TS-2000, which is quite adjustable. For now I'm using it wide
open. I know the centre signal is 1600 Hz, which is quite high. How
high/low do the sidebands go?
