1828 - unk mx, possibly pan pipes? Just a little above the noise. I could hear it but mostly couldn't
see it on the monitor - I may be an OM (literally!

but I still have right good hearing.
I started Audacity running in case there might be an ID or 1830 s/on but no joy.

Anyway, whoever you are, wherever you are, you did get into here at near noon local time...
FWIW: I usually keep the rcvr parked on 6925 USB with the volume turned way down.
