Interesting - looking closely I can see what might be very short burst at 77Hz at around 0400 UTC and what might be a similar short burst at 75Hz around 0645 UTC.  I can't see anything else except for the 4 minute burst at 82 Hz around 0530utc. This burst is usually the precursor to the main transmission 90 minutes or 150 minutes later - perhaps checking the transmitter. This morning, however, there has been no 0800 utc transmission.

Around 82 - 83 Hz area there seems to be other activity as well as zevs. Observed what looks like short bursts periodically, maybe not related but strange these short bursts are around this frequency area and not visible elswhere. I did see a short burst also on 77 Hz
at 0407 utc this morning.
No interest in this activity other than checking RX sensitivity and Antenna.
