Yes Central uses 154.3100 for Fire and EMS Ops, which Midland Park had used with them prior to going to Wyckoff. Midland Park FD has MCS2000s in the Chiefs Vehicle and 1st Due Engine to Monitor Police Only, So I suspect they would want to have the ability to monitor PD in that capacity again. One has to wonder if Wyckoff may go to Central as they are discussing closing their dispatch due to the loss of Midland Park. I also hear Central from time to time using TAC3 155.8425 NAC632 at night for DL runs and sometimes for traffic details during the day, I do not believe there is a repeater on 155.8425 seems to be only P25 Simplex unlike 158.7300 which I'm guessing will be P25 with a repeater when the work you say is completed. I do know Wyckoff had budgeted for new radios since their mobiles and portables are 15 years old, unlike Midland Park whose officers have 7 Year Old HT1250s so if they decide to go to Central they will have budgeted for replacement radios and will be ahead of the game in that situation. Not all of Wyckoffs Infrastructure is 15 years old however. They replaced the 20 year old Centra Comm II dispatch consoles with Zetron Integrator RD Touch Screens which are similar to what Central uses, in addition I believe there is a voter system installed as well in the past 10 years after the Cedar Hill Tower by 208 was added. The Fire Department was using 154.3475 192.8 with a Repeater during the Labor Day Fireworks, the Ops frequency 150.7825 does not appear to be the input with or without an additional PL tone.
Yes; 155.8425 is simplex at this time. This frequency had been used only by Glen Rock's DPW. Glen Rock and Ridgewood PD "tactical operations" were, for many years, taking place on 153.7850 (SPEN 4) - it was referred to locally as "Channel 3." However, it was accidentally discovered that neither community had an FCC license to conduct base station operations on SPEN 4, so base station operations there were halted. It was rumored that all new VHF frequency coordination requests were frozen indefinitely by the State, so it was decided to use an existing licensed frequency - 155.8425. Initially, the only authorized base station location was at a school in Glen Rock; coverage was poor. Now they're authorized to use the water tank on Glen Avenue in Midland Park, so the coverage should be much better.
The long range plan calls for the conversion of 158.7300 to a P25 repeater (actually, the repeater will be multi-mode - capable of both digital and analog). Many of the new receivers are in place, but there are still several very poor reception areas. Also, dispatch consoles had to be replaced at Central because whatever consoles they had were not compatible with P25. I'm not sure if the new consoles are installed yet. The P25 migration will not take place until: 1) all fiber lines are installed, 2) all new receivers are in place, 3) new consoles at Central are installed, 4) both communities are satisfied with the analog coverage.
As for Wyckoff coming to Central, I question how busy 158.7300 would be if Glen Rock, Midland Park, Ridgewood, and Wyckoff were all using the same primary repeater. If Wyckoff is going to move over, they should make the decision quickly - then Midland Park and Wyckoff may be able to continue using 158.7825 in analog mode, via existing base station infrastructure, with Central just doing the dispatching instead of Wyckoff.
I guess Wyckoff's other options include Bergen County, Mahwah, Allendale, or Franklin Lakes. Not sure if any of them besides the County are equipped to handle another municipality. I believe Midland Park investigated a couple of them and wound up signing on with Central.
