These two Official Observer reports were sent by the same Kilocycle Kop, Ed, for the same "rough tone" complaint over a span of 3½years. Interestingly, I was using different transmitters each time. And yes, I was having trouble with the transmitters at these times.
So thanks Ed. Without your diligence, I would never have experienced the thrills of receiving Official Observer reports.
View the culprit responsible for the first OO report.
52 Years after these OO reports were received, K9FH received another OO report. This time it was for having a signal with "chirps" while operating during the 2018 Novice Rig Roundup with a modified DX-20 transmitter and homebrew VFO.
And the modern OO reports for chirp just keep on coming! Chirp chip chirp chip, chirp chirp chip chirp!
