It really threw me for a loop when I started hearing analog audio coming from MARCS all of sudden. In fact some of the MARCS talkgroups I had programmed into my scanner starting popping up but the voice traffic did not match the talkgroup at all. I did not find that talkgroup 13344 in the Franklin County database but there are several 13000-series talkgroups on their system. Just a hunch.
1. If the transmissions were digital, it wasn't the Franklin County system.
2. 868.4875 is the primary control channel for the MARCS Columbus simulcast site.
