I currently use the ARC500 software with a cable to download site frequencies and talkgroups from the Radio Reference website into my RS Pro-106 scanner.
My intentions are to be able to monitor the ARMER trunking system, as I travel throughout the state of Minnesota.
I have already selected and imported ALL site frequencies, and ALL talkgroups from the RR website for the ARMER system, and have been monitoring local area talkgroups for quite a while now.
My question / confusion is this:
When I open the ARC-500 software, and look at the trunk system frequencies for ARMER, it only shows 32 frequencies. There are a LOT more site freq's that were imported to the scanner.
Is this a limitation of the software, or the scanner?
Do I have to manually change these 32 freqs when I travel to include the freq's for different parts of the state?
I currently have modified the 32 frequencies to include a primary and alternate freqs for my local area.
All the talkgroups for the entire ARMER do show up in the ARC-500 software.
Any insight / help in understanding the trunk system site frequencies would be appreciated.
Thanks in advance.
