BBC R&D: How to test a loop antenna

Many thanks to SWLing Post contributor, Alan, who writes:

Thomas,

You have had quite a few posts on loop antennas. I found a technical article about how to accurately test them.

I have just come across this article which you may find interesting. It comes from the BBC Research and Development:

It is written by a real Broadcast Engineer.

Thanks for the tip, Alan!

Tom recommends SWL YouTube channel from South Africa

Many thanks to SWLing Post contributor, TomL, who writes:

I wanted to share with you a YouTube channel “SWL” from Andre in Johannesburg, SA. He is an avid SWLer and routinely does head-to-head comparisons of portable radios. He has been doing weekly Radio News the last couple of months and has a very pleasant delivery of news and reception reports. Let’s give him some love and share his YouTube channel on SWLing Blog so people can be introduced to him. He plans to keep doing these weekly news readings as long as there is interest. In this video he talks about:

    • Tecsun PL660 discontinued, PL680 will be higher priced.
    • AWR stops using Moosbrunn, Austria site.
    • BBC Somali broadcast inconsistencies.
    • Two reception reports from Istanbul and India.

Exploring Aviation Signals: Gander VOLMET Meets HFDL on 13270 kHz

Many thanks to SWLing Post contributor, Egil, who shares the folowing:

Hi Thomas,

I have been rather inactive on the radio front for most of the year, but every now and then I just have to check the web to see how others are doing.

And when I read Carlos’ article last night about the Canadian VOLMET stations, it brought back memories.

Because every time in the past I have heard HFDL on 13270kHz, I have also heard Gander Volmet on the same frequency.

That also happened last night (November 3, 2024). A short recording is attached. The signals were received with an ICOM IC-R75 connected to an indoor Wellbrook 1530 loop antenna mounted in the attic.

I have wondered for years why I always hear both Gander Volmet and HatYai HFDL at the same time on this frequency, and never just one of them. And usually they both have the same signal strength here just outside the city of Kristiansund, Norway.

All the best!

Many thanks for sharing this, Egil. I, too, have always enjoyed monitoring VOLMET stations–I’m certain it’s due to the fact I’m a bit of an aviation enthusiast. Cheers!

Hi Thomas, I browsed a Video stock library when I thought about checking it’s Radio collection.

Among the usual mics and mixer sliders there where these shots/

I’m sure it won’t take long for the spotters to tell us more about these sets.

Readers, if you can ID these radios for Adi, please comment! Not much context in some of these beside a beautiful dial–a proper challenge.
