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?

Dear everyone,
I finally decoded DELFI by RASCAL. It is very difficult to tune for decoding. I got only 2 packets.

Masahiro-san,
For tuning a waterfall spectrum display is very, very useful. I am running WSJT6 with the SpecJT window in parallel to RASCAL and I copied during this first week nearly 1200 packets.
