OK, so found this on a website..

UHF PMR446 Chan. 01 .... 446.00625 MHz NFM
UHF PMR446 Chan. 02 .... 446.01875 MHz NFM
UHF PMR446 Chan. 03 .... 446.03125 MHz NFM
UHF PMR446 Chan. 04 .... 446.04375 MHz NFM
UHF PMR446 Chan. 05 .... 446.05625 MHz NFM
UHF PMR446 Chan. 06 .... 446.06875 MHz NFM
UHF PMR446 Chan. 07 .... 446.08125 MHz NFM
UHF PMR446 Chan. 08 .... 446.09375 MHz NFM

When entering these freqs into a radio would you enter them as displayed OR as below?

UHF PMR446 Chan. 01 .... 446.0625 MHz NFM
UHF PMR446 Chan. 02 .... 446.1875 MHz NFM
UHF PMR446 Chan. 03 .... 446.3125 MHz NFM
UHF PMR446 Chan. 04 .... 446.4375 MHz NFM
UHF PMR446 Chan. 05 .... 446.5625 MHz NFM
UHF PMR446 Chan. 06 .... 446.6875 MHz NFM
UHF PMR446 Chan. 07 .... 446.8125 MHz NFM
UHF PMR446 Chan. 08 .... 446.9375 MHz NFM

My radio has only 7 digit display and it will not allow me to input the freqs as they are in the top lot.

Help please!

Radio is an Alinco DJ596 MK2

Cheers

2 446.019
3 446.031
4 446.044
5 446.056
6 446.069

A 6.25khz step is needed to get PMR frequencies. The closest I can get to them is as follows:

446.0000 PMR446 Ch1
446.0125 PMR446 Ch2
446.0250 PMR446 Ch3
446.0375 PMR446 Ch4
446.0500 PMR446 Ch5
446.0625 PMR446 Ch6
446.0750 PMR446 Ch7
446.0875 PMR446 Ch8

You've got a fair amount of "slack" with frequency on FM, it isn't anything like SSB which does need to be spot-on.

Just looking at the frequency counter against my DynaScan PMR and it says, for example, 446.092/446.093 on Ch.8, or 446.067/446.068 on Channel 6 . . . The little Cobra reads a clear 446.092 on Channel.8

But I got shocking Feedback when I keyed-up the Cobra on 8, because the Dynascan was nearby on the desk, despite the Dynascan being RX on Ch.9. Obviously a "bit wide" at very short range.



Not that I would USE the Dynascans on anything other than 1 to 8 . . . of course not . . . just because the channels go up to about Ch.80, on 431 Mhz . . . at 2w :whistle:

446.0625 PMR446 Ch6
446.0750 PMR446 Ch7
446.0875 PMR446 Ch8

If you can change the frequency step to 5 kHz you can get very close. I did this with a Yaesu VX-7 a few years ago:

UHF PMR446 Chan. 01 .... 446.00625 MHz NFM = 446.0050
UHF PMR446 Chan. 02 .... 446.01875 MHz NFM = 446.0200
UHF PMR446 Chan. 03 .... 446.03125 MHz NFM = 446.0300
UHF PMR446 Chan. 04 .... 446.04375 MHz NFM = 446.0450
UHF PMR446 Chan. 05 .... 446.05625 MHz NFM = 446.0550
UHF PMR446 Chan. 06 .... 446.06875 MHz NFM = 446.0700
UHF PMR446 Chan. 07 .... 446.08125 MHz NFM = 446.0800
UHF PMR446 Chan. 08 .... 446.09375 MHz NFM = 446.0950

Welllll, Channel nine cannot possible really exist as there are only EIGHT Legal PMR Channels in the U.K. . . . . So it must be a dream or a figment of the imagination. :whistle:

On the Continent, "Mainland EU" they do have different PMR Regulations, so a PMR Set intended for EU operation has more channels than a UK one. . . . As usual, here in Britain, we've got the meanest, smallest most-restrictive radio legislation.

My PMR has "Channel 86" curerently showing on its display. . . . . But that doesn't exist so it must be my imagination, or bad eyesight. ;) :whistle:

Or Channel nine on your Intek 505 could even be one of the 10mW LPD433 settings.

Dont know if he's giving us B/S**T or not, i did monitor pmr8 for a while and it did seem to me he was using it for work purpose's.

Awesome! The Police move on to tactical frequencies and encrypted TETRA but they're so broke they issue sets that can be intercepted on a £4.95 Kiddie-set from the local toyshop. That's priceless and could only happen in Britain.

Sounds to me more like they keep the real radios to themselves and issue the toys to the PCSO's... ;-)

I suspect there's probably a LOT of truth in that comment too.

Get that around here a lot. the most stupid use I have heard so far was a slinger (also known as banksman) using it for a tower crane. These guys were moving tons of kit around the site using a pmr radio & the consequences of another using passing the site with a 5 watt radio when they are on milliwatts is not worth thinking of :clap: :clap: :clap:
Incidentally the River Police on the Broads use marine band. It's a good listen if anyone is around here. Drunks, dangerously handled boats, over loaded boats, fires it's all there.

I can't say I've ever done such a thing but 20w into a high gain antenna at quite a height dissrupts BUSINESSES using PMR's quite a bit.
They can apply for a bloomin business license!

A few of us have been considering setting up a small free membership group & applying for one of the PMR licences that only covers mobile & handheld use. It only costs a few pounds & there is nothing in the rules any where that says you cannot use it for general chat or anything about the number of radios permitted.
All that's required to get licensed is a cheque & completion of a form.
