Hi Geret,
I have some friends in Sweden that use something like this, no one seemed to
know what freq they were on. When a few of them came here to the US we were
talking about this and I showed them my Motorola GM 68, ICOM U16 and GE MPI II
and GE PCS radios I have on GMRS. They loved the range of these and wondered if
they could use something like this back in Sweden. I looked all over the
Internet for information about this and could not find a thing. But now you
mention PMR, I am going to focus my research there.
Where in the UE are you by the way?
Many thanks for all that good info!
Richard

For the record, most countries in EU have license-free radios in
3 frequency ranges:
- LPD (Low Power Device), 10mW, 433.075 - 434.775,
68 channels in 25 kHz raster.
Not so polular beacuse 10mW doesn't get far in cities
- PMR (Public Mobile Radio), 500 mW, 446.000-446. 100,
8 channels in 12.5 kHz raster:
1 446.00625
2 446.01875
3 446.03125
4 446.04375
5 446.05625
6 446.06875
7 446.08125
8 446.09375
These radios generally have PL support.
Note that in EU, the 70cm band is 430.440 MHz so it is out of
our bands here.
These things are VERY popular - recently bought 2 radios for
$35 together with charger and NiMh cells!
- Digital PMR, 500 mW, 446.100-446. 200,
This is like the analog PMR but uses digital voice (this is what
ICOM developed D-STAR for)
Note that the American FRS/GMRS radios are simply illegal here, as
these frequencies were used by law enforcement till recently
(so not a good choice even to "chance it").
You indeed might want to take this into account when setting up
repeater frequencies.
Hope this helps,
