Find a radio frequency

Postby DazTheDJ » Thu Jun 15, 2017 2:32 pm

Hi, I want to know the best way to find a local frequency. I know I can scan but so many none chat things are picked up scanning I struggle with it. There is a local event and the organisers have PMRs, I want o see if I can listen in. How, using an RTL dongle and SDR# can I scan for PMRs without picking up a million other things?

thanks in advance

The chances are the organisers will use a PMR Light/simple licence so check those frequencies first.
But really just scanning the most probable PMR bands is best option if you are not there with a way of finding the frequencies. Things like Close Call are great, but if you are not there, then band scanning is really the only way.
I often do band scans & to be perfectly honest, it is quick & simple, just listen for a few seconds, make a guess & a note of anything you stop on & then move on.
During a 15 minute band scan I can get dozens of hits & have an idea if I want to listen for longer to anything.

With SFR+ look between 165 and 169 and 451 to 459 to find most users, and in those two bands you'll find most local stuff will be clustered in small groups so are easy to spot.

what sort pf event, and what area ?

Nobody uses uk gen / simple light at events for running them.

Hired sets will be on one of the short term hire freqs, but larger events will have an allocation which could be anywhere - as an example last weekend, wildlife was in the old home office police band, with a capacity plus trunked mototrbo system.

I can think of several places local to me who do. I live in a tourist area & a lot of the local tourist attractions use simple light & then when there is a weekend event. That is what they use for that too.
Some places have their own licence with a private frequency or a site licence. But as a whole those frequencies are known.
Some information about the event would help. If it's at a local museum or small tourist attraction for example, then the chances are it will be different to something on say a military base or county showground.

Got to say I agree with Alane here in the coastal area - people hire stuff from me all the time, and most times it's all on the hire frequencies, but quite a few regular users find it cheaper to buy kit and licence it simply - and maybe use out two or three times a year. Capacity Linked Trbo systems might be the case for BIG systems, but fetes, gymkanas, horsy stuff, scouts, music events and this kind of stuff will be anywhere the licence takes them.

A lot of groups like the Scouts, St John Ambulance, some of the Military Cadets etc operate on a nationally held simple light licence & just have their own local radios. At £75 for 5 years for every St John event in the UK, that is great value.
Other places use either the the simple light or the similar site licences that allows them to use cheap radios that cost less to buy than a few weeks hire from most of the commercial sources of hire radios.
For a large bonfire event that I helped to organise a few years ago. We used radios borrowed from both City Council & I believe it was Army Cadets. The two radios sets could not talk to each other. But with a bit of thought, that gave us a set for organisers & anther set for our helpers, with one person communicating between each.

Be sure to check all the frequencies listed in this OFCOM document, they are often used for short term hire purposes:

http://static.ofcom.org.uk/static/busin ... sLight.pdf


PMSE frequencies seem to be increasingly used too, especially at UHF (upto 470 MHz).

Check the Frequency Allocation Table PDF (Annex H) for the bands:
https://www.ofcom.org.uk/spectrum/information/uk-fat
I reserve the right to ignore people who have made no attempt to the read the manual, and expect others to do it for them.

sorry, let me clarify :

'no decent event who values their safety would use uk gen, as every man and his dog are on it'.

and 'no radio hire company who values their clients would use uk gen'.

There was me thinking our hire department knew what they are doing when they use short term hire freqs for customers, and temp Ofcom / jfmg freqs for large events.
