The P.M.R.'s transmit a radio wave. The strength of radio waves
are measured in Watts (the same Watts used to measure electricity).
The maximum strength that our license permits us to transmit is 5
Watts. When you can buy (legal to buy, illegal to use) 100 Watt
power boosters (also known as burners) for C.B. sets, 5
Watts does not sound
much. It is in fact perfectly acceptable for the type of use
REVCOM make of their sets. On a good day, it is possible to cover
30 miles or so. It is unusual for an event to cover more ground
that that. If the control centre is in the middle of the event,
that gives you a 60 mile diameter working area.
