In the early 90's almost any type of receiver would pickup the famous "russian woodpecker".

Rapidly becoming one of my favorite channels.

Very cool! Great viewing your videos watching them down here in New Zealand :)

Cool hack! The story of numbers stations seems like a good fit for this channel... 😉

Someone check on this guy and make sure black helicopters with Virginia farm boys arent rappelling down into his home.

Great video. Thank you!

Just a small distinction, but one that's still debated so don't take it too seriously. UVB-76 (and really any of the Russian buzzers) aren't technically considered number stations by the enthusiasts as they're considered military in origin, and also don't really seem to send messages too often. Most intelligence agencies (especially the CIA) are strictly civilian, so even when Garry Powers was shot down over the Soviet Union, he technically wasn't lying when he said he was a civilian. I've seen people make the distinction between how CIA and KGB agents operated in the field, with CIA agents often being a lot more independent with their intelligence cell keeping their distance from each other to avoid all being caught if one is exposed. While the KGB built extensive spy networks, where information was funnelled through key handlers who'd use things like dead drops to pass said information around. Not saying one worked better than the other... But it might explain why the west gives us number stations, and the east has buzzers.

Nice

Where can I learn more about the hardware/software setup? Connecting the SDR to the phone and decoding the CW using an iPad are of particular interest.

What hardware and app are you using? My experience varies when using a cheap RTL dongle and an USB OTG cable.

I think this subject is ripe for a collaboration with @saveitforparts
