John, Thanks for the in-depth look into my capture. I think I've got an answer to what's going on. You're right, it isn't Opera. You said it looked like one of the wsjtx modes. It has to be, and where it's positioned on the band, it's most likely fst4-900, a qso mode. The reason I couldn't decode it is that the software wouldn't let me decode on the freq it was on. I just wrongly figured that it was using another mode other than a wsjtx variant.That's what threw me. The solution was to dig into the wsjtx manual and find out that you can't have too wide of a bandpass in that mode, as set in the wsjtx program. Once I narrowed down the fst4 range that the signal appeared in, it let me "look" at that freq in that mode. I think this was an "upgrade" because this is the first time I encountered this problem. So, bottom line is that I can find out who is transmitting there now, and I'd bet it was K9KFR looking for a qso. Sorry if this took up too much of your time John when it just turned out to be "op error" on my part. I've never had to deal with the "powers that be" you mention. From what you've written, I think I'll stay clear of asking them any questions... hi. 73 John, Ray
