472-479kHz available Jan 1st 2013 in UK

G3XBM's 500kHz transverter. Ideal for 472-479kHz.
OFCOM are now going to renew NoVs for the 501-504kHz band for existing permit holders and this will be possible via an on-line webform on the RSGB website.
"Following the agreements concluded at World Radiocommunication Conference 2012, Ofcom has started discussions with the RSGB and others about the timescales for implementation of the new secondary allocation to the amateur service between 472 and 479 kHz which, it was agreed at the Conference, would be effective from 1 January 2013.
Ofcom has therefore determined that, to allow these discussions to be completed, the current NoVs to allow experimentation between 501 and 504 kHz should have their validity extended to 31 December 2012. This notice confirms this fact."
See http://www.rsgb.org/operating/novapp/500.php. So plenty of time to get an antenna up and a TX or transverter ready. You might like to start by looking at http://sites.google.com/site/g3xbmqrp/Home/500k where I describe my 5W QRP transverter which will work on 472-479kHz. I've plans to make a Mk2 version of this during the summer with higher power and other improvements. It would be nice to make a PCB this time so that others could build it.

A new MF ham band agreed at last

472-479kHz was officially agreed as a new secondary allocation for radio amateurs at WRC-2012 today.  See http://www.arrl.org/news/amateur-radio-gets-secondary-mf-allocation-at-wrc-12 .

It may be some months, or even a year or so, before the band is available in the UK. I already have kit to use on the new frequencies (my 500kHz tranverter) but may update it with a better antenna and a bit more power.

7kHz doesn't sound much but it is much better than the 3kHz available by NoV around 500kHz currently. Also it is likely to be available in most countries with EIRP somewhere between 1 and 5W depending on footnotes and location.

A 472-479kHz band?

Latest reports from the WRC2012 conference suggest the possibility of a secondary amateur allocation between 472-479kHz look "promising" although this hinges on a crucial meeting on Tuesday Feb 7th. Some countries remain against an amateur allocation, but the majority do support one, with caveats. A 7kHz wide worldwide allocation would be a good outcome, so keep fingers crossed for a few more days.
