I've never heard of any of those devices. I am pretty sure there is not. In fact as I understnad it, it's illegal to own certain radio transmitters over here (whether or not you ever turn them on). 27MHz AM CB sets are one thing that it's illegal to have over here (although I rememebr a curiousity that in some circumstances licensed radio amateurs could own them if they intended to convert them to the 10m band). I do recall reading about people being taken to court for using illegal 'video senders' (basically low power TV transmitters so you could watch the output of your VCR on any TV in the house). The normal penalty was confiscation of the equipment, something I don't want to risk (I don't want to spend time designing soemthing to have it confiscated, worse I don't want any of my clasiscs confiscated, nor to I want to lose my amateur radio license, somthing that generally happens if you commit an offencee like this).# As I mentioned, there were 'Wireless micropghone' designs in some of the electronic kits. They were such low power that they were essentially undectectable outside the house, so you'd get away with those. And there are type-approved radio modules on licesne-exempt bands that you can use (which are, of course, what we've been discussing). AFAIK, the only transmitter you can legally homebrew and use in the UK is an amateur band one, used in accordance with an amatuer radio licesne (which is _not_ suitable for this sort of thing, it's contrary to said license for a person to tranmit to himeslf, for example) -tony
