I have not recently seen this weekends, and the current WRTH lists this as mtwtf.. So...
There definitely is carrier there, and that is generally detected long before audio, at least in the last few weeks. Whether it is suppressed or vestigial, I don't know.
It is hard enough to get audio let alone knowing if both sidebands are there. My logbook notes suggest that the USB is the best bet, and that is how I have been setting up the receiver if I am going to leave a recorder on for unattended monitoring. I do believe that I have seen something in the LSB, but will keep a sharper eye open for that in the future.
That is a very nice recording!
