While this one is not a huge problem, it happens too. Visitors come to Las Vegas from a lot of foreign countries. People in the UK have whats called PMR radios. It's their FRS service. The radios are all simplex, 8 channels on 6.25Khz splinter channels starting at 446.000 Yep! if you scan those channels here you DO hear activity on them! 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, Geert Jan PE1HZG

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!

Re: [Repeater-Builder] Re: license-free radios
We get the canadian grand prix auto race here in june. A british media crew brings their own handies, whiuch happen to be on simplex 444.975 which is the input to montreal repeater VE2RJS. They have no idea they are coming over the ham band, its only for a week and its fun to listen to. Indusrtry canada doesn't really bother with ham problems much anymore. So when the race is over and they pack up, the interference goes with them.
