That would be a good guess about the former uses of the low band freqs mentioned, but I can't remember what was what.
In the beginning.....only a few years before I went to work for the NCSHP, there was only 1 NC channel: 42.620 simplex statewide. Troops ran A thru F.
VA was on 42.860 simplex.
Williamston (A), E-town (B), Raleigh (C), and Greensboro (D) all had 3KW transmitters on this freq. Salisbury (E) had the local site at Salisbury and a 70 MHz linked site at Poore's Knob in Wilkes Co. Asheville (F) had the local at Asheville, and linked sites at Mt Meadows, Wine Springs, Chambers Mtn, Soco Gap, and the mother of them all on the top of the observation tower at Mt Mitchell. Output power was "only" 330 watts, but the antenna was 70 feet above the 6684 foot ground level at the peak.
Later in the 70s, another similar power output station was added at Mt Gibbs (Clingman' Peak) southeast of the observation tower site to cover the holes that the observation tower site couldn't "see." Actually it was more that the observation tower site couldn't always hear the mobiles to the SE in Troop F, and since the newly installed state microwave site was already on Mt Gibbs, adding another linked site was a cake walk. As for the mobiles hearing the Mitchell site, you didn't need anything but a 1 iron and a resonant filling to hear the Mitchell site. Hell, Williamston and Etown comm centers could copy Mitchell anytime of day when monitoring channel 1, and mobile reception of the Mitchell site was normal on the Outer Banks at night.
Troop A communications also had two sub stations (1/4 KW "low" power) that operated each day 7AM to 11PM. They were Elizabeth City and New Bern. Troop B also had two sub stations that operated the same hours. They were Fayetteville and Wilmington.
Then came semi-duplex operation in NC with channel 2, 42.780, as a mobile-to-base freq, and 42.620 remaining the base-to-mobile and car-to-car channel.
VA added 42.88 simplex. Or maybe it was the other way around....whatever.
NC added some more 42 MHz freqs for SBI, some for DOC, and some for ALE. Most of these are what now make up the current SHP channel selections.
In the late 60s came channels 3 and 4. Troop A, B, D, and F were on 1 and 2, C and E were on 3 and 4. More remote receiver and transmitter sites were added
As UHF and 70 MHz links were added, E-City, New Bern, Fayetteville, and Wilmington comm stations were phased out as no longer necessary.
As the population and corresponding traffic increased and more roads were built, troop zones were re-aligned and new ones added, and troopers and frequencies and comm sites and comm centers were added. Channels 5 thru 8 were added.
As the need for more SHP freqs came into play, some of the the old comm center-to-comm center VHF high band repeater links and freqs were converted to a high band repeater system, and some were used with low to high crossband car repeaters for troopers to use outside the car. Then the agencies that had been using exclusive low band freqs were assigned new radio freqs, and some of the low band freqs were placed into SHP use.
PL was added to the system in the late 80s.
There's more, but it's time to crash for the night.
They are just about anything you can imagine. One he tells about was chasing one up a riverbed until both cars lost their oil pans. He has pictures of a large moonshine still the ABC officers, now known as ALE and some troopers raided and busted up. That still was using sugar stolen from a school or a warehouse for scholls, not sure which, and car radiators pulling water from what looks like a swampy pond. Must have been some really nasty lead laden moonshine.be kind of interesting to hear some of his bootlegging stories...
Thanks much for the recap!Salisbury had only channel 1 until the 60s when 2 was added, then used 3 and 4 troop wide when those were added in the mid 60s. 5 thru 8 were added to the state low band plan in the late 70s. IIRC, Iredell was one of the counties on 5 and 6 when that took place and the troops were re-aligned and Newton was added as a comm center in that part of the world. Newton began dispatching NWNC at that time and took over the Poore's knob site. When Troop H was formed to manage the Greater Charlotte area and Monroe got a comm center, more frequencies were added, more sites were added, and everything west of Raleigh got re-aligned and the whole state was divvied up channelwise.
