Possibly. The U.S. 2m band is 144-148 mHz, the U.K. is 144-146. Most
radios sold in the U.S. are able to transmit on the entire band. It
would work in the U.K., but there may be legal restrictions on importing
them. At one time didn't the police use channels in 146-148 mHz?


70CM is different. The FM portion of the band in the U.S. is 440 mHz,
in the U.K. 430. Some handhelds will transmit on both, some won't.
Again there may be legal issues about importing a radio that transmits
"out of band".


The other issue is repeaters. At one time all Euopean repeaters used a 1750 Hz
tone to "unlock" them. This was transmitted to bring the repeater out of standby
and during normal usage it was not needed once "unlocked".


U.S. repeaters never used the tone, if they used anything (and by now probably
all do), they used subuadible continuous tones (CTCSS or the Motorola trademark
PL). From what I understand the U.K. is moving over to CTCSS also, but you
may encounter a repeater that uses the 1750Hz tone.


Just as an aside, check about 6m and 220mHz. Here 6m is not available for
FM, and there is no 220mHz band at all.

I thinki take it from the responses that i might be better off not
buying a handheld in the USA for use in the UK. Given that most will
come with only 110v chargers and i will need to use an adaptor, the
lack of toneburst (albeit most repeaters now use CTCSS) and the
differential 70cms frequencies. The £1=$2 makes the prices VERY
tempting and i could buy a top of the range handheld for the same cost
as a run of the mill one in the UK. Lastly, most of the warranties
would mean i had to ship it back if it went wrong.


Any other thoughts.

Year and a half ago I bought Yaesu VX2R in the US - works fine in EU.
Has 90-240V charger (just needs the pwr socket adapter), toneburst and
switchable deviation. Warranty of course only 1 year, but at the US
prices it's worth the gamble. If it died today, I would just pitch it
and get the new VX3.

If i could find a similar spec handheld BUT with a higher output than
3 watts that would be ideal. I was looking for something with 5-7
watts output and a decent battery life.

Thanks
