Yeah, V02a had a problem last night with the transmitter (surprise!) during that time slot on 6768 kHz and the carrier was dropping out on voice peaks. Resulting in essentially DSB during the audio, and AM when the audio was low or between words.
Yeah, I don't normally pay any attention to V02a,s ince so many people do document it, but I stumbled across it during that time period and noted the poor transmitter performance. Later, during the 0900 time slot, SK01 (V02a's digital mode sister station) had other issues with the transmitter 9063 kHz, so it could have been sourced from the same TX. M08a was also up on at the same time (0900 time slot) on 7681 kHz and with no audio issues. But then the V02a/M08a/SK01 family use many transmitters, and sometimes you can hear audio crosstalk of one of them in the others transmission.
