Everyone seems to want to stay with their own TRS. MB, NMB, Pal800, and the Horry systems keep things jumping. I was down for a day last week (close friend's death) and I noticed the MB system sounded pretty bad, like it was off freq.
Mostly I monitored NMB & the county TRS's. I heard a few SHP units on the NMB & Conway towers. The coverage on the Horry system is great to the west. I was picking them up all the way to the Florance Co. line using a RS 800mhz duck on the back of my Pro2053 mounted to the dash on my car. Horizontal also
Is there any info you're looking for in particular?
I used a P93 file from someone (can't remember who) and I'll be adding to/correcting some things. It had a few TGs mislabeled.
