color=#0000ff size=2>434 is within the UK/EU amateur allocation, it's also a
"spot" frequency (well, close by, 433.94something) for general unlicenced QRP
(mW) devices such as garage door openers and car security systems. With
all the hassle and fall out as you might imagine, due to some political Euro
Numpty making a technicaly uninformed decision years ago. Here,
70cms (430-440) is also shared with the military!. It's the only reason we
still have a presence there, they can tell us to QRT at any time if
needed.</FONT></SPAN></DIV>

in/arround London for the 2012 Olympics, much as they did in Oz years
back. Did they ever get it back I wonder?</FONT></SPAN></DIV>
