FYI: I have found that the programming software that comes with the Uniden 296D/796D has a significant bug when dealing with Motorola VHF and UHF trunking systems:
The program doesn't always allow you to change or modify the tables as you would like them, and it fails to properly clear this data from the scanner itself once it's entered. I found myself climbing the walls trying to monitor a local 406 MHz system here in the States. I kept programming the base, offset, and spacing, only to have the old data return every time. However, I cured this problem by manually deleting all the old info and setting the values to "O." Once this was completed, I downloaded the bank to the Uniden software program and it reset everything as it should be. Then I was able to correctly program the system into my 796D with no further problems or missed radio transmissions.
I still haven't been able to get it working, It detects I-Call, but not any Activity IDs or TalkGroups. Any Other Ideas, Uniden have been less than helpful :x .
