Recorder Catch on 6925.050 USB
I have a het here which came on at 0355z to cover the weak ute which was here most of the evening. Het was about 550 Hz, and very little audio was heard except for a brief bit of OM talk around 0415. After around 0515 the het dropped to around 500Hz, and stopped at 0530z at which point the ute was not heard .
