If you have access to one, try entering the FCC ID at the site above.
Sometimes you get lucky and there's lots of technical data with the FCC application.

>I need a very low cost wireless thermometer to cover 30 miles (near

>Needs to be low cost.

>It occurred to me that boosting one of these very low power
