RS232 by Radio

almost zero noise

Linx had an LC series, which were incredibly easy to use due to the receivers data output
being very stable in the absence of the RF carrier.

The trade off, of course, was range. They have since dropped the LC series in favor of the
LR (LR stands for Long-range), which now offer 10 times the range of the LC series due to
the increased sensitivity of the newer LR series receiver.

The trade off here is that the newer LR series receivers output random noise. This is what
he's now having to deal with.

If you toss a pair of simple encoder/decoder ICs into the mix, this noise is no longer a factor
since the decoder IC will validate the inbound data several times before changing the logic
on the decoders output.

Ioannis;

What's the sensitivity of your receiver in dBm? If it's anywhere near the Linx LR receivers
sensitivity, we might be interested in stocking your receivers.
