What the * is this noise?

[riveter]

Hey guys, stumped by this:

Suddenly started receiving this a few minutes on SYSCOM 47.66 in Catonsville MD at about 25' AGL with a very very short (2") stub antenna, PSR-800 stationary at 5x5 strength. Very weird noise, sounds like dolphins clicking, as you can hear, quite repetitive. I assumed it was a signal aberration, but I couldn't baffle it out- very strong signal. Figured I'd post it as a curiosity, linked to Google Docs download of the .AU file.

Sounds like Over-The-Horizon or backscatter RADAR otherwise known as the Russian Woodpecker

Sounds like interference from an old rotary dial telephone :lol:

Radio Shack Firmware Updates

Just a quick question, does Radio Shack normally keep up on there firmware updates? Have they made any significant changes in the past? I am hoping they release a CQPSK firmware update very soon. Until then I have a $600 paper weight! Thanks everyone!

God, we're old. That's what I thought, too....like someone was repeatedly dialing zero....
