Radio nerditry: looking like another active weekend for shortwave pirate broadcasts. Stations audible in DC right now on 6950 AM (stereo!) and 6960 AM.

@mattblaze Stereo shortwave? That's a thing? How?

[mattblaze@federate.social]

@x0 you can do AM stereo with different channels on the upper and lower sidebands. But only the pirates seem to actually do this.

[sig_ug@infosec.exchange]

@mattblaze What do these pirate stations broadcast? Sea shanties? Trotskyite debates? Live tiddlywinks tournaments? Inquiring minds want to know.

[x0@dragonscave.space]

@mattblaze What the Wikipedia article calls independent sideband, then? Kahn's system? Rather than C-QUAM?

[x0@dragonscave.space]

@mattblaze Which is basically what, SSB per-channel?

[mattblaze@federate.social]

@x0 right, AM with independent sidebands. Demodulates as mono on a regular receiver

@mattblaze nothing on 6950 here in Florida or on my radio at home in NJ. Got something on 6944 in both locations, though. 6960 is noisy but audible

[mattblaze@federate.social]

@thereisnocat 6950 seems to have gone off the air. Getting 6944 here now, with a pretty decent signal.

@sig_ug@infosec.exchange @mattblaze@federate.social all of the above, and then some.

[thereisnocat@toot.cafe]

@mattblaze HF Underground says it’s Sternradio, and was on 6950 but moved to avoid QRM from Ballsmacker on 6960. So same station.
