Title: Cluster beacons move out of 40 m ham radio band
Post by: SV1XV on May 23, 2015, 1724 UTC

The cluster of single letter beacons which operated for years near 7039 kHz, recently left the 40 m amateur radio band and moved up to new frequencies. New frequencies are:

7508.7  "D"
7508.9  "S"
7509.0  "C"

Thanks for the updates! Just today I heard two of the 10,782 beacons so I'll keep an eye on this group.

Hopefully the Wiki is updated to reflect the changes in the 7 MHz frequencies.

That's kind of a shame. They were a good propagation marker near the QRP watering hole.

I'll have to give 'em a listen in their new home.

A single letter beacon "T" (https://pbs.twimg.com/media/CJP8M8kUwAAOWCh.png) (or a plain dash) is heard in Athens, Greece every evening just above 7010 kHz.

Good signal tonight from beacon K on 7039.3 kHz (http://sv1xv.blogspot.gr/2015/10/mx-beacon-k-on-70392-khz.html), after a long time.

Anyone here on the HFU can update the wiki. Just log in with the name account name and password as you use for the message board. You can edit pages, or create new pages.

Wow, I have to get a proper SDR receiver.

Great catch
