Default PL Tones

A local business that I am trying to pick up has a PL tone of 103.8, that was programmed by their radio provider, Is there a way to manually put it it a Pro-651? I have tried everything.

103.5 should work. I know of no PL decoder that is THAT picky.

And tell them to get a radio provider that knows what they are doing.

You have probably already tried 103.5 without success so it is most probably another PL tone being used. Could it be 173.8 ?

Go into the West Virginia forum and state the company and frequency and somebody there could then probably give you the correct PL tone.

And just a reminder you don't need a PL tone to monitor a frequency. You would only need PL if you are trying to identify different users on the same frequency.

Actually the Radio Tech told me directly that they programmed those PLs like that on purpose. So I will try to monitor the frequency without a tone and see what happens. Thanks for all the advice!

The difference are 0.3% and standard spec for professional radios are that a CTCSS/PL decoder must not be narrower than 0.5% and max 3% so I do not think that those 3 tenths of a Hertz makes any difference to a scanner. I beleive my AR8200 sometimes even decodes the neigbour CTCSS tones.

Your problem lies somewhere else.
