Has anybody used the Radiometrix RF modules?
In particular, I'm interested in experience with the SLIRX and TXM modules.

Yes, the 443mhz units.
The sensitivity and selectivity of the rx is well
within the published spec's (similar to a good dual conversion
communications reciever) The selectivity impressted me the most,
If I remember correctly it was over 65db down at =/- 1mhz
I have not tested them at a fast data rate though.
With the 10mw tx I have had 5Kms line of sight using 1/2 wave dipole's

We cannot blame God for creating a World with so many problems,

No wonder Eve recommended Apple.

I am using these in a logging project. I am right in the middle of it now
but have programmed the units and all looks fine. I am using the RPC-BIM
units at 433.33MHz. I started this some time ago and would now use a
transceiver from Pan Atlantic at 900MHz if I had to make a choice again.
This is FCC approved and gives good range and data throughput to 9600 baud.
It also has direct rs232 input.
I am using a 16C73 in one case and a 16C74 in another. They do take 9 lines
to drive them whereas the Pan Atlantic only requires the two lines (rs232 in
