Fluttery and weak signals on #shortwave #hfradio But also auroral dx propagation on VHF!

Elephant cage antennas! Whoa, just imagine the fun one could have listening for distant signals on one of them. For research, a 900 ft diameter one was built in Illinois. In West Virginia, the Navy had two built for diversity reception. Amazing. #swl #hfradio #sigint

This IS a wild story! Prince, before and after his nane change, lurking on early internet services.
Y’all wanna hear a wild story? Charlie is right — this medley Prince made 30 years ago, blending many of his greatest hits & fan favorites into an extended mashup, is one of the most fun “only Prince could do this” things he made in the 90s. BUT: he told us he was gonna do it. In an AOL chat room…
Unpopular opinion: the Purple Medley is one of the best things Prince ever did.

The BBC has become gutless organization. To call them sheep is disrespectful to sheep. I quit listening to their news because they REPEATEDLY took Trump at face value, without fact checking. BBC cannot be respected if it does not respect truth.

Radio Nacional da Amazonia was strong tonight, and sounding fabulous on the sync AM demod. It was pretty luxurious with the bandwidth set to 12 kHz. Received on the K3FEF RX888 / NovaSDR in Pennsylvania.

I'm cheering for Yuri. He's a tough kitty; he endures.
Yuri is cleared to have the second surgery Dec 19th. There is some slow healing, but not surprising given he was dead for a bit there. No infection. No pain.
To recap: he died during surgery, they revived him, he's now doing great. They'll re-run the bloodwork again day of surgery.

I'm drilling down on "The Divided Dial" season one from @onthemedia.bsky.social / WNYC. It was a mystery to me how AM talk radio turned to such crap, as I observed in the 1980s and 1990s. Long before the 2000s. This is the history, starting with episode one.

Trump seems to think that nuclear wepons development depends on testing live bombs. No, development does NOT require actual nuclear blasts.
Testing live devices is just a dick wagging contest, as H bombs can be made ARBITRARILY LARGE and doesn't scare any adversary actually seeking a fight.

I couldn't let this week go without reviewing HOUSE OF DYNAMITE — which gets right to me the four core principles of nuclear thrillers. Most of all it should serve as a reminder why Trump's nuclear threats this week are so dangerous: www.doomsdayscenario.co/p/trump-s-od...

The "Divided Dial" may be the BEST documentary ever made about the history of AM talk radio and far right shortwave broadcasting. I heard a lot of those broadcasters in the 80s, 90s, and 2000s.
Excellent work by Katie Thornton and others at WNYC. They nailed it.

One first step people should do to respond to this is start using the “report a speed trap” function in Apple Maps to report where ICE is operating. Make Apple party to the attempt to protect people.
