Anyone using these in projects ?

I fired mine up and came to the conclusion that it was picking up garage
door openers and my weather station as well.

Seems it might be better to run it rf on is equal to a space and no rf is a
mark ?

Comments ?

Just imagine what it would be like if the garage door opener and the weather
station did that... (though they couldn't due to battery life, but you get
the idea)

Why not just add some checksums to your data and re-send each message a few
times at random-ish intervals of approx. a few seconds?  A pic or similar
could do the decoding.

that'd be the way to do it, an idle RS232 line is marking.
