High over
Southwest Pennsylvania
,
this is the N3FB repeater!
Operating since 1991 with 1,000 watts of radiated power and receiver sites
in Canonsburg, Scenery Hill and
Pittsburgh
, it is my goal to make it very easy for you to get into this machine.
Each receiver site ‘listens’ on the input frequency of
448.650 MHz with a PL tone of 131.8. That site then retransmits what it
‘hears’, on a different link frequency, to the main site in Canonsburg.
There a LDG voter selects the best audio and routes it to the transmitter on
443.650 MHz using a PL tone of 131.8. Oftentimes the receivers are switched back
and forth while in mid-conversation without the listeners even noticing it.
The N3FB machine establishes a link with the N3RNX machine that operates
on 146.955 (-) with a PL of 131.8.
During times of utility power outages, the system continues to operate on
standby batteries. The system operates at a reduced output power in order to
conserve those batteries. This can be noticed by the short tail and also the
change in the initial announcement to a generic one that says “this is the
N3FB repeater”.
Comments, suggestions and questions are always welcome.
