Abacom RF Modules

I am not familiar with the Abacom units, but I have had others overload the
receiver with the transmitter too close. Have you tried them with 10 foot
separation? The units I used were ~433 mHz and only needed a few inches of
antenna for 10 feet.

I am trying to do domething a little strange. I am trying to use a receiver
and transmitter [noparse][[/noparse]Abacom RF Modules] to send serial data between 2 stamps.
BUT I need to keep the range of transmission to less than 10 feet. So far I
can't seem to get them working when the 2 stamps are right next to each
other. I have heard that the Antenna requirements for these modules are very
particular. Does anyone have experience with them?

Yes, you're almost certain to swamp the receiver with signal at such close
range. Try moving the modules father apart...For such limited range, could
you use IR?
Just a thot, Duncan
