	If that is a true 4 watt rf output system then it should transmit
much farther than what you are receiving now.  In any transmitter system,
the single most significant improvement anyone can make to their transmitting
range is through antennas.  Remember the CB boom?  There were literally
dozens of antennas to pick from, each one having its virtues and failings.
The absolute worst antenna was the one that converted your regular AM FM
broadcast radio antenna into a CB antenna.  In answer to your question,
and solution to your problem, FCC rules notwithstanding, is to replace
the antenna.  CB radios have a 4 watt output and cell phones have a 25
watt output (if I remember correctly).
