I quite often hear different companys on 165.4375mhz and have realised that
they operate a CTCSS tone squelch system through a community repeater. The
system works by sub audible tones opening the squelch of the recieving unit
which is tuned to the same tone meaning that several companies can use one
frequency but only the squelch of the recieving set will open if it recieves 
the
same tone as the transmitting set.
Now this system is ideal for a community repeater which are normally based on
hills soo as to increase the radio range.  I am located in Barrow In Furness 
in
Cumbria and I would like to know  if anyone can help as to where the location 
of
these repeaters are in my area. One is on 165.4375 and the other is on 
165.400. 
the input frequencies I would assume are 4.8 mhz higher which is standard vhf
split.
