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.
