Used to it was ok to use a CB radio. but theses days there are tracking devices on the radios. May be out in west Texas there needed.
Yea there is radio scanners that cost much. Some 10 thousand each. Still to be a ham radio operator takes lots of dinero and learn the morose code.
There was these trans ocean shortwave radios that had may be 25 plus channels but .
they ant worth a crap these days.
