Loggings > North American Shortwave Pirate
AM Stereo 1620 6955 AM 0130 UTC 9 June 2023

WKHB, an oldies/Talk station in Irwin, PA. runs C-Quam on 620. If you're not in the area, it's a tough catch, 5.5 KW daytime, 50 watts nights. You can hear it in mono with a regular radio, but that's no fun.
I'm thinking that old 1620 AM Stereo station was from Toronto, but it's been so many years ago I can't remember?

As with C-QUAM, there is a pilot tone with the kahn system as well, at 15Hz, Magnavox was 5 Hz. This would be another tell-tale of stereo transmission.

What are you doing up, Redhat?

A good signal here on the SDR recording. I checked for a 15 Hz pilot tone, and did not see one.

Sounds right to me. I sent an email. The fact he says “You may contact this teeny-weeny radio station” definitely seems to indicate this is a part 15 operation. Maybe retransmitted by the same guy that runs the 1620 transmitter?
