Well, I'm not too sure about the difference in Smartzone / Smartnet so idk what to look for when explaining the upgrades and simulcast mess, if someone will get me up to speed with that, I'll get the skinny on it.
I imagine that they will at least keep the VHF net intact, mainly for interop purposes. Just like any other county in NC, the big FDs with money have 800 capability, but the outskirt VFDs are doing good to keep radios in the trucks. There was an upgrade not too long ago to the radio system as well, back when VIPER was known about, so I don't think (if our local leaders have a brain) will spend all the extra $$$ and trash a system which seems to be working extremely well already.
I've been keeping an ear on VIPER constantly lately and even "searching & storing" while at school, but the only activity I get is the local SMAT check in & SHP. No VMN TGs or MAMA contact or anything as of right now. I'm hoping that will start changing soon.
