Tuning RTTY with scope.

Recent RTTY contest, Feb 2025. First time tuning a signal with a scope. There were a lot of operators. I think the filters on the AEA PK-232 I was using are pretty wide. So I was able to decode signals. But there would be a lot of trash mixed in from nearby signals. I was using the AEA Pakratt software. Pretty clunky compared to the HAL P38 software. But the HAL does not have scope mark space outputs.
