HF Beacons / Re: S

« on: October 20, 2023, 0255 UTC »

This is an explanation for the S beacons heard recently, posted on UDXF mailing list, in reply to my logs there:

It is Russian Navy Maritime Patrol Aircraft Morse net. The ground control sends S Markers for 5 minutes every 30 minutes to inform the aircraft radio operators that the net is available. Sometimes you will get S Markers on multiple frequencies such as 4651.0 kHz CW, 6752.0 kHz CW, 8821.0 kHz CW, 10021.0 kHz CW... Aircraft usually operate on 4671.0 kHz CW or 8830.0 kHz CW. Aircraft will send 4 figure radiograms and the ground control will receipt the radiograms.

10/11 meters / Re: What Is Freeband 11 Meter Free Band CB Radio Export Radio Info

« on: November 14, 2022, 1629 UTC »

Awesome.  So Greece currently has... just 26.965 MHz to 27.405 MHz (40 channels) + 27.415 MHz to 27.855 MHz (or 27.885 MHz?) in de facto 5 kHz steps? 

Yes! 40 channels 26.965 to 27.405 MHz (listed one by one) plus a continuous allocation 27.415 MHz to 27.855 MHz, which usually are stepped every 5 kHz by the freebanders.

10/11 meters / Re: What Is Freeband 11 Meter Free Band CB Radio Export Radio Info

« on: November 13, 2022, 1643 UTC »

In Greece, since December 31, 2021, freebanding is legal !

Accrding to the current frequency allocation tables, CB radio uses the regular 40 US channels: 26965 - 27405. In addition, CB is allocated on a secondary basis 27415 - 27885 kHz without channelization !
