Beginners Guide to 5 MHz

If you’re a UK based advanced (full) license holder then you already have access to 5 MHz without the need for any special NOV’s. Most modern radios will already transmit on 5 MHz, others will need modification or wideband for TX. If you have tested your radio on 5MHz and it wont transmit then you could take a look at mods.dk

So lets assume your radio is ready to go..

5 MHz is not like other amateur bands, we don’t have one continuous allocation, more segments of activity.Like the primary user its best to stick to USB on 5 MHz, although technically no reason why you couldn’t use LSB ! The band has pockets of activity, some frequencies are used for CW, Data and Phone. All of the frequencies I quote will be USB dial freq, and these could form the basis for you to program into memory channels. While the new allocation can be portrayed as “band segments”  it’s often easier to think of discreet channel numbers.

If you hear another amateur calling CQ be sure to check the band allocation as not all channels have been harmonised. This can even apply to returning a CQ call from another UK amateur, check before you transmit !

You can download a PDF of this guide to keep by your radio here.

A PDF visualising the band plan is available to download on G3NRW site. The RSGB have also provided a guide online.

The RSGB provide a handy guide to ensure all of your signal remains in band.

Power is limited to 100w from your radio, and amateurs are secondary users (MOD is primary) I would suggest additional care is taken to ensure you always operate in band and identify your station call sign at regular intervals. Operating away from your main station address is permitted either /P or /A but no mobile usage is permitted.

The band is ideal for short range NVIS contacts during the day, typically 50 to 400 miles, and after dark the band does support some further DX. In the winter the band often closes shortly after dark, but in the summer it will support short hop NVIS all night.

The band does support various digital modes CW, JT65, JT9 and WSPR. The centre of activity for each mode.

CW – 5260 and 5262

WSPR 5287.2

Olivia 5366.5
