Unication G5 will not trip on P25 Phase 2 Dispatch talkgroup

[policefreak]

So our county recently added a patch on our P25 Phase 2 700mhz system seen here Burlington County Public Safety (P25) Trunking System, Burlington County, New Jersey - Scanner Frequencies
to our VHF Fire/EMS Dispatch. The quality is fair but not great. I have had success getting the G5 to trip on the new patch for most of our Fire and EMS Crews. There are 2 companies that have tones around 313, 346 that will not trip using the patch. They work fine on the VHF analog frequency. I triple checked all of the settings under the knob, verified the correct tone frequency ranges were selected, etc. Could it just be too low a tone frequency for the pager to pick up in P25 Phase 2 mode? For the record I have 2 G5s and both have this issue. I have reverted back to FW V1.30, V1.31, and the new V1.32 Beta with no luck on either pager.

If you think the patch sounds bad, imagine what the pager thinks. Your going to have a hard time tripping the pager if your patch is not clean.

what are the 2 tone pairs for the companies that wont trip and give me one or 2 pairs that are working. The digital side of two tone paging unfortunately has a range for each frequency of tone. Instead of being able to pick 2585hz directly you have to pick the calue that has that in its range, ie. 2499-2590. where that becomes a problem is if the two tone are within the same range.
if some of the companies are working i would think the quality of the patch is not the problem, usually it works or doesnt.

So while they are very close they are at least one group away. So I am wondering if being how close they are the pager can’t differentiate the difference in tones coming through the patch, I know the analog to P25 patches on our county system usually sound horrible, with the tones that are further apart it can activate but the very close ones not so much
