Two questions. Is it necessary to put the repeater imput frequency into the scanner. (473.4000)? Also Franklin Lakes FD/EMS And DPW Dispatch 158.9400 IF I have it in as 131.8 will it still pick them up?
The input frequency and PL Tone is what the repeater listens for prior to "rebroadcasting" the signal at a higher wattage on the output frequency.
If what you are listening to is in the immediate area to you, you might be able to listen on the input, but it is not necessary if you are just listening.
