DK’s Barn Find: A GE Super Radio II

My good friend, David Korchin (K2WNW), has a knack for finding diamonds in the rough.

He’s been known to find a radio that needs TLC, take it home and restore a bit of its former glory. He’s had some amazing luck in the past.

Recently, DK sent a video of of his recent acquisition: a beat-up GE Super Radio II he purchased for two dollars. This radio will win no beauty contests, but it still plays well.

Many thanks, DK, for allowing me to post this video. It goes to show you that you should never pass up an opportunity to adopt a Super Radio. Even if the telescopic antenna is all but missing, the internal ferrite bar is where the money is!

Play on!

Standing Inside a Broadcast Transmitter While it’s ON!

I stumbled across a video from the fabulous Mr Carlson’s Lab YouTube channel. If you haven’t check out this channel before, and you are really eager to learn more about electronics, this is a wonderful YouTube site.

So, in the latest episode, Mr Carlson takes us on a tour of a very large Gates BC-250-GY broadcast transmitter from the 40’s era. Lots of big tubes, transformers and capacitors! This is an old mediumwave transmitter that he has restored. Although the technology has changed markedly since the 1940s, the basic principals of transmission are still present. And, interestingly, he points out that this particular unit was in regular service right up until as recently as 2003!

It’s an interesting show and even if you can’t grab onto all the technical information presented, I think you will enjoy looking at technology from a past era.

73 and good DX to you all,

Gary’s mediumwave DX FSL antenna phasing experiment

Many thanks to SWling Post contributor, Gary DeBock, who shares the following note about his latest FSL antenna experiment:

Medium wave DX FSL antenna phasing experiment– 1593-CNR1 (Changzhou, China, in Mandarin) boosted up to strong (S9) peaks by two 5 inch “Frequent Flyer” FSL’s at 1435 UTC on February 25th in my frozen back yard in Puyallup.

Unlike other high gain MW antennas, the FSL’s can provide cumulative gain at very close inductive coupling ranges.

Amazing, Gary!  Thank you for sharing this excellent bit of DX!
