Hi,

  I recently came across an advertisment for radio transmitters & receivers
which might interest some users.

A company called Radio-tech in the UK is offering modules from 0.25mW to
10mW designed for data transmission. I haven't tried them myself, perhaps
someone on the list can comment on their usefulness.

The address is:

   Radio-tech limited, Overbridge House, Weald Hall Lane, Epping, Essex.

Phone:

   UK sales   0181-368 8277    International sales +44 1992 57 6107

Web:

   http://www.radio-tech.co.uk/


As usual - I have no connection with the company.

Keith.

I've used those modules (0,25mW, 433MHz), with limited success...
They're supposed to make a link at up to 200m, but I only got about 25m,
when using a helical-antenna. When swithing to a whip-antenna (both home
made) I got about 50m though (outside).

I had a problem with the modules, as their BW was about 10KHz, and I was
using a digital encoder/decoder running at about 5KHz. I never made it
working, but used a DTMF-encoder/decoder instead, which worked great.

Radio-tech offers a broad range of modules (418, 433, 170MHz - 10KHz-20KHz
BW - different power-radiation).

I just looked at there web page and they are the same units as
radiometrix (http://www.radiometrix.co.uk) and LPRS
The wide band 418mHz units I've had very good results from
The 173mHz not as good but still not bad

his wife was asked to comment. She said that as his wife, she
had been the first to notice this problem
