Shortwave listening and everything radio including reviews, broadcasting, ham radio, field operation, DXing, maker kits, travel, emergency gear, events, and more
Yesterday afternoon, I spent a few hours sorting through old radio books and magazines. I discovered this issue of Monitoring Times from September 1993:
Today marks the 20th anniversary of 9/11; a day where we honor all of those who were lost, their families/friends, and all of those who who served during and after the attacks.
This morning, I’ve been listening to a number of off-air shortwave radio recordings made on September 11 and 12, 2001. Many thanks to the amazing contributors at the SRAA who shared these with us over the years. For this radio enthusiast, these recordings brings back memories even more vividly than video coverage.
I built another Tferrite, (TFERRITE 2), for medium waves–this time also with the shortwave option.
A single variable capacitor, 800 pf, and a primary winding on the 2 ferrites of about 46 turns, a secondary winding of 3 turns to pick up the signal and send it to the receiver.
On the PVC tube I wound 4 more coils, for the shortwaves, connecting the ends to the same variable together with the other ends.
I interposed a switch on one end to eliminate or insert shortwaves.
I am sending you these 3 links from my YT channel where you can see the tests I have done in these days with no propagation.
The yield in mediumwave is excellent, like the other one, yet also good for the shortwaves–to be so small it compares very well.
Let me know what you and the whole SWLing community think!
Thanks to you and a greeting from Italy, Formia on the Tyrrhenian Sea. 73. Giuseppe.
This is brilliant, Giuseppe! Thank you so much for sharing your homebrew antenna projects. It seems they work so well from your beautiful urban location in Italy!
Many thanks to SWLing Post contributor, Kris Partridge, who shares the following:
I belong to a FaceBook group “The Broadcasting Club” and [recently] there was posted a link to a YouTube video of a 70 year old 1951 US Army film called “The Independent Radio Station WMCA”. It’s worth a view to show what the thinking was 70 years ago:
In 1951 the US Army made this film showing how an independent radio station operates. There was certainly a cold war propaganda motive for the US Army to produce this film, but today, when independent stations are a rarity, this film gives a detailed view of how a large market, independent radio station, WMCA New York, went about producing its programming and paying the bills in post war America.
Many thanks to SWLing Post contributor, Carlos Latuff, who shares the following:
I bought a small analog radio and I’ve been listening with it.
On September 4, around 17h48 UTC, I heard a strange signal on the band of 13 kHz, since it’s not a digital dial, I don’t know precisely the frequency but maybe if your readers may listen to the signal they may tell what it is about.
It almost sounds like the preamble to an SSTV message, but I’m not sure about that noise that’s in between. Readers, if you can help Carlos ID this signal, please comment!
