I have a two channel Minitor V, that, when in selective call F2 or scan, will alert each time someone transmits. The pager is set up for the Motorola tone system. F1 monitors and alerts normally with no problems. F1's tones are in group 6. F2 has group tone of 634.5 (122) and both A-B tones have a B tone of 634.5. This channel's DPL is 627. I believe this is my issue. Is the tone deviation on this pager "too loose" and is the group tone too close to the the PL and is decoding as a page? The pager was setup on a single wideband channel and when we narrowbanded they were changed to two channel, one for fire, and one for EMS. So, F2's frequencies and PL are all new and the tones were kept so the old tabletop encoder could be used. There were no plan to use pagers after the switch, but several of us like to carry them when on call versue portable radios. There are other firemen with pagers that work fine in this configuration. Is this something that can be fixed with PPS or does this have something in the hardware or firmware that needs be fixed?
