What do you mean when you say settings? Are you using software to prgram this system or are you doing manually. Have you set up the band plan from the custom table?

Using radio pro-197

Yes i programed the info from radio ref database, into radio

Radio shows good signal but does not pickup any talk groups

Custom table on radio also has Hi channel and Lo channel settings not show in radio ref database

Hi/Lo Values:
500.3375/25.0/380 ChLo=380, ChHi=429
501.9125/25.0/430 ChLo=430, ChHi=449
502.5125/25.0/450 ChLo=450, ChHi=759

I'm not yet familiar with the GRE digital scanners so I can't offer any specific tips other than to make sure you're programming it as a Motorola Type 2 UHF system and that either you have talkgroups programmed and unlocked or you're searching without any lockouts.

Morris:

380 519 380 471.000000 12.500
520 759 520 476.000000 12.500

Sayreville:

380 759 380 499.125000 12.500

Edison:

380 599 380 470.000000 12.500
600 759 600 477.000000 12.500

If you are using Win500, the data I posted above will fit the 'custom tables' cells exactly - just copy from the post here & paste into the software.

I have almost every TRS in the tri-state area in my 500 - whatever you need, I got you covered. If you are using Win500, I can even zip up my P500 files & e-mail them to you, just send me a PM...

It looks like W2SJW provided all the data you seek however here is the rule of thumb for calculating those low/high values for Motorola UHF systems. It won't work for APCO systems and doesn't apply to EDACS and LTR.

ChLo for a particular table entry will equal the offset value. Often (but not necessarily) this is 380 for the first table entry.

ChHi for a particular table entry will be one less than the next higher offset value. Using Somerset as an example, the first entry's ChHi is 430-1 or 429, since 430 is the next higher offset. The second entry's ChHi is 450-1 or 449. The last entry's ChHi, where there is no higher offset, will be 759.

If there is only one base/offset/step entry in the configuration then the ChLo will equal the offset (usually 380) and the ChHi will be 759.

Note that this is a rule of thumb. It will not always work and I won't complicate things by trying to explain all the unusual circumstances when it wouldn't work, but this would be the first thing to try for a new system where the data isn't in the database. (Or post a query here, a bunch of people would be happy to help.)
