Hi folks,

For those of you who are regular users of 40 metres, I have a question for you... According to the RSGB Band Plan (effective from 29th March 2009) - IARU Region 1 General Conferences, the frequency of 7.090 MHz is the SSB QRP Centre of Activity.

http://www.rsgb.org/spectrumforum/bandplans/rsgb_band_plan_2010_files/sheet005.htm
Just click on the 40 metres tab at the bottom of the page...

When I'm on that frequency, I can hear a CW beacon (or similar) in the background. Although it's a frequency that recommended for QRP, I don't want to call CQ if it's used for something else.

Any ideas?

None seem to be centered on 7.090 MHz ...... It could be a "renegade" beacon that is uncoordinated.

Did you manage to read the callsign of the beacon? I know there are a group of beacons centred around 7038KHz, they are intruders, this might be another one.

Ian -

Depending on the time you are hearing this CW signal .....
you may be hearing 40 meters operations from Region 2 (RTTY, CW and data).

Is it even an amateur beacon? The Russian military operates a few beacons in the 40 metre band; and they sometimes use 7090 to send radiofaxes - see here:

I managed to find out who and where it was coming from, thanks to a fellow member of our local amateur radio club who's a whizz with CW.

It appears that it's SL0FRO, a station belonging to Frivilliga Radioorganisationen.

Here's a list of their training transmission times and frequencies...
