The Radio Society of Great Britain (RSGB) has made a proposal for radio amateurs in the UK to have access to frequencies between 501 and 504, or 508 and 515kHz, at a transmit level of 10W EIRP. The allocation, if accepted, would extend amateurs’ experimental work on other low and medium frequencies and thus aid understanding of propagation in those parts of the spectrum. The two frequency band options are proposed as they are no longer used for maritime telegraphy in the Western hemisphere and their usage for non-directional aeronautical beacons is being phased out. It is understood that it is unlikely, in the near future, that the channels will be re-allocated to another service. Further details of the RSGB proposal can be found on the Spectrum Forum website.
