Ok...real fine....I assume these boards are measuring a parameter every so often and sending data back to "home base". May I ask what you are measuring? I don't need to know. Is home base receiving data from any other transmitters?
What kind of antenna is the receiver using and how is it polarized? How far is receiver from transmitter?
Pictures please of uncovered receiver.
Now we need a way to measure output from receiver.
And I need to know what kind of test gear you got.
Let's start with that.

rj, yes I see your point. With the transmitter moving and that border edge signal, I would think a higher frequency link is needed. 460 is my limit and I can hardly see that anymore. I am sure that there are microwave experts here that can help. I am not familiar with MW gear. I would think there are OOK modules.

Also, maybe RFID is a possibility. I'm not sure of the range or power induced.

I will stay tuned to see what happens.
