New P25 System...I'm Lost

[KevinC]

I just checked my x36 Sentinel, and the bandplan (more like LCNs) are there for such a system.

This is for the Waterbury system???

This is for the Waterbury system???

No - it's for a different EFJ P25 Implicit system.

I believe that Waterbury's radios are ignoring the bandplan that is being sent. Perhaps the EFJ radios have a software option for not allowing changes to the bandplan.
The bandplan that works in those Uniden scanners in Waterbury uses 851.0625 as a base and not 851.00625, the step is 6.25 and the offset is 0.
The information sent by the CC resets the Base to 851.00625 thus causing a problem. Interesting that it now appears in another system.

Do you have a RR URL for Waterbury handy?

If that is an Implicit system, the "base" will be the actual frequency for that table number. The step would not matter since there is only one frequency per table.

OK. The one I'm talking about is UHF, so that may be the key difference. Waterbury may also not be an Implicit system.

The Lewis County, NY is an EF Johnson system. UHF range
I just need to know if this is isolated to the T/XT series. But there apparently isn't alot of these systems around to determine that i guess

My guess for a custom band plan would be:
Base 451.00000
Step 6.25

That would give the following frequencies:
453.15000
453.26250
453.31250
453.36250
453.55000

There is something with the 396XT/996XT era scanners that causes the band plan to be overwritten with EFJohnson P25 systems. Waterbury CT does the same thing.

What would the Ch-lo, Ch-Hi, and offset be, trying to get a Whistler programmed now
