With a transmitter emitting 1 W, your RF analyzer will not pick up 1V of signal strength. And the intresting thing isn't what it sees exactly at the center of your transmitting frequency. It's what it sees to the sides. And what overtones it sees. Don't you realize that uV signals are strong enough to disturb if they are leak transmissions at the wrong frequency?

Sorry but no. Very much no. Even modules of that power are not safe. Even modules requires you to test your equipment in a shielded room, to make sure that you do not leak RF energy through supply voltage or data signal lines.

The equipment I work with do use modules of this power or higher. And we have spent significant amount of time measuring and optimizing the layouts just to make sure the device fulfills all regulations.


Different pool,different fish.(I mean frequencies regulation)

That frequencies with that power used "freely"..maybe didn't notice that GMSK or CMR used by our goverment organization and public also.

Better we strictly to the case instead "horse debate".Sorry

Thank you
