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!

Address for WSY70 New York VOLMET?

4 Replies

Perhaps you can help SWLing Post reader, John Cooper:

I have a mystery I am trying to solve. Apparently there are 2 VOLMET stations with the same call sign of “New York Radio.” The address I am looking for is from WSY70- New York Radio. The address I was given is a different station that uses New York Radio as a station identifier, and is located in Bohemia, NY. It is a AIRINC Com Center station with the call sign KEA5.

WSY 70 is a New York FAA Flight Service Station. I have searched all over to no avail for an address. The frequency is 6,604 kHz USB.

The station manager from the other NY radio KEA5 said the transmitter site was located in Barnaget, NJ; remember that the Bohemia, NY address is a different station, not WSY70.

Hopefully someone out there can be of assistance. Thanks in advance for any assistance.

Please comment if you know an address for WSY70.

Bermuda…Missing?

“Uh, Charlie, where did Bermuda go?”

My good buddy, David Goren, directed me to the VOLMET frequency for New York Sunday afternoon on 3,485 kHz.

VOMET, for those of you not familiar, is a worldwide network of radio stations that broadcast TAF, SIGMET and METAR aviation weather reports on shortwave radio, and in some countries on VHF, too. All of the reports are broadcast in upper sideband, using automated voice transmissions.

At any rate, they must have experienced a glitch which resulted in the loss of meteorological data for most of the United States. The broadcast preamble is as usual, but as soon as specific airport regions (mostly major US cities and some islands) are mentioned, the report takes a disturbing turn. It’s fodder for science fiction–one is not sure whether to be alarmed or amused by this eyebrow-raising data (or, lack thereof).

The end result becomes almost like a numbers station, sans numbers, of course. Take a listen for yourself by clicking here to download the recording, or listen via the embedded player below:
