Title: Kids on 446.0 MHz
Post by: W0RW on January 26, 2019, 03:56:23 PM
I have been hearing kids using HT's on  446 MHz.
I got a beam heading on them but they make very short transmissions.
Most times just 2 way chatter with low deviation,  some times with 'Roger' beeps.
Then I got to measure their exact frequency, it is 446.005 MHz.

446.005 is a PMR (Personal Mobile Radio) Frequency used in the UK.
So someone in our city might have gotten hold of some UK radios.
446.005 is one of their channels.
That doesn't help to find them but it helps to know what they are.
See: http://ukspec.tripod.com/446/freqs.html (http://ukspec.tripod.com/446/freqs.html)
and a full listing of UK Freqs at: http://ukspec.tripod.com/specbw.html#b400 (http://ukspec.tripod.com/specbw.html#b400)
Still 'T Hunting' in Colorado.

Why assume UK radios?  Couldn’t they be using standard ham HTs set to the 70cm national simplex frequency?  Probably just Baofengs slightly off freq.

You are right they could be EU radios.

We get the same problem here in the UK, Brits visit Walt Disney World Florida and buy a couple of FRS sets there to use around the parks, bring them back to the UK and use them, the Ministry of Defence take a very dim view of them being used on their frequencies  ::)
