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. Vy 73, Viktor OE1VKW
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?

Hello Bruce,
When the main signal is on 1600 Hz you see on the waterfall display two stronger signals at +/- 600 Hz (1000 and 2200Hz) and minor signals in 150 Hz intervals from 550 to 2650 Hz. I didn't try a narrower bandwitdh, just using the normal USB on a IC-910.

The only decode I got the other day was by manually tuning as well and I was able to SYNC enough to get one line of information, but the sat drops out of the way fast and had no more. Nothing heard during the last pass at 1735z...

Now to mark down the seeds frequency and few of the others and see if I get decode.

Thank you many advice.
My PC does not seems to run WSJT program and RASCAL at the same time.
I will try and challenge.
