Re: Why not use PL tones? said by dispatcher21:I thought that what the problem was, sporadic interference? I did not know the interference was constant to the point of them not being able to communicate with their equipment. And yes, I know how PL tones work, we use them on our radios here and they filter out quite a bit of interference we get on our fire channel. With the PL tones off, we get a constant buzz and warble, we turn the PL tones on, the noise is completely gone. Whats causing the noise? We guess that its CSEPP across the river but the PL tones solve the problem for now till we can figure it out completely. The interference of BPL is similar to what you are describing with CSEPP. Not only is it constant but much stronger and over a much greater frequency range.
As for the noise problem you are having, there are several possible reasons; bad transmitter, signals mixing, harmonics, etc. |
