Check out Radiometrix in the UK - they have a web site and make units that are competition to Linx - a little more expensive BUT they are FM and thus more immune to noise etc. They have distributors world wide.

I heard from the list about linx technologies company providing cost-effective radio modules called LC series (350 feet, 4800 bps). I had a look to the data sheets from their web that seemed to fit my application needs. When I ask to order 3 emitter/receiver modules (I'm just a hobbyist), I was answered I had, as a prerequisite, to buy their evaluation kit first before buying any parts. Did anyone experience this before? Thanks for any person of the list that already bought linx parts to get in touch with me by e-mail. Benoit CELLE -
