I never answered your question in the first post...its 3600.
If you are near the edge of reception, you may get something called motorboting noise. E.g., sounds like "under water". Test decode rate by pressing MAN in the bank with Hill. Line 4 on display should reveal 36: 6227 xx%. The 6227 is the system ID for all four of the Wasatch Front Federal sites. and the % number is the decode rate. If it falls below 50%, this may be your problem...that would likely indicate your receiver is to far from the transmitting tower.
The other possibility is that some talkgroups are encrypted which you can't do anything with. Nothing in the Database indicates any encryption. The letter under Mode would be E rather then D if encryption was used.
