I’ve been breaking in a new S.A.T controller, gradually learning my way around it. I couldn’t help but notice that especially on the CAS twins there are FT4 signals all over the pass band throwing QRM in the middle of the passband and even above it. I thought we had a gentleman’s agreement to keep FT4 and cw below the middle of the passband and toward the bottom end? I guess not everyone got the memo 🤫

It's likely people are forgetting to select the data doppler line in satpc32 for CAS 4A and 4B. Reminder to hit the button so we don't put FT4 where people are trying to use modes other than FT4.

Same thing on a late RS44 pass last night. I was in a SSB QSO at around 435.637 when a “5” station started an FT4 CQ sequence right on top of us. Got worse when another “5” started calling the first station. I sent my call with “QSY DN” several times and actually heard one of the stations move down while transmitting. All in all, pretty clueless. 73, Craig N6RSX

Yes rather frustrating. Don’t they follow the general rule regardless of the frequency- listen first? Hopefully they will realize the problems they are causing.
