Channels in the 144MHz Band to be used for the Commonwealth Games




From the RSGB website:

Following negotiations with the RSGB to minimise the impact on radio amateurs, Ofcom has announced that it will temporarily authorise up to four 25kHz channels, between 144.000MHz and 144.100MHz, for the period 22 July to 4 August 2014, to support the operation of the Commonwealth Games. The frequencies to be used specifically exclude 144.0500MHz (CW Calling Frequency).
Usage of this spectrum by Games users will be geographically limited to an area centered on Glasgow, defined with a UK NGR of NS 585 650 and the surrounding areas covering a radius of 30 kilometres between 23rd July 2014 and 4th August 2014. Specific use of this spectrum will be limited to handheld equipment operating on a maximum of 5 Watts output. The frequencies affected are:

• 144.000 MHz (Centre frequency with a channel bandwidth of 25 kHz);
• 144.025 MHz (Centre frequency with a channel bandwidth of 25 kHz);
• 144.075 MHz (Centre frequency with a channel bandwidth of 25 kHz); and;
• 144.100 MHz (Centre frequency with a channel bandwidth of 25 kHz).
Ofcom emphasises that use of Primary Amateur spectrum is only for the specified time period and does not constitute a change of usage.
Ofcom are aware of the very short notice and will authorise this usage on a “non-interference, non-protection basis”.  Amateurs in the Glasgow area are requested to avoid these frequencies until 4th August.
