I've noticed that alot of CB radios, handhelds for example, have a maximum
allowable transmit rating of 4 watts. I was wondering, is there a way to
boost this beyond the 4, or is it a factory setting which cannot be altered?

Not looking to violate FCC rules, just curious if it can in theory be done,
how it might be done, and what might be an advantage.

I notice they have a receive range of 7 watts, so I'm wondering why have
such a higher range of receiving, if you can't transmit within the same
area. Seems abit unfair.
