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.
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.
