Are all the DEP outputs, parks and fire, using 179.9 PL? (At one time I thought a couple were on a different one.) Temperature inversion this morning was driving my scanner crazy. PL might at least limit what is heard to just DEP. Thanks.
For the most part, the DEP is currently using an output CTCSS tone of 179.9, except the Forest Fire "A" channels, which use an 82.5 tone. However, this may change when narrowbanding is implemented, since a DCS tone sounds better on a narrower bandwidth frequency. It is unknown at this time whether DCS tones will be used or not, but I heard it's not out of the question. I also understand that P25 digital mode may be implemented further down the line, depending on funding, so I wouldn't be surprised if you hear a VHF channel or two in P25 mode (F/W uses P25 on the NJSP TRS already as a primary mode). However, VHF P25 would be many years down the line I would think...
The other tones listed above are the input tones to the repeaters, however a few are not listed and I know of one that is incorrectly listed.
The primary Division A repeater (7 North) which was located on Milton Firetower atop Bowling Green Mountain in Oak Ridge has been removed from service following the loss of an amplifier circuit. Until that situation is remedied, Division A units will be using NJ DEP Channel 1 as their primary repeater. Please note, the Channel 7 south repeater, located in Hunterdon County, is still operational...however it's location limits access by Forest Fire units in the northern counties.
DEP Channel 1 output is 151.190 MHz, with a PL of 179.9 and the input frequency is 159.300 MHz. There are multiple repeaters on that system which are accessed with different input PL tones.
Current operations in Division A only are as follows:
"Hill 1606" repeater, with an input PL of 131.8
"Ramapo" repeater, with an input PL of 123.0
"Montclair" repeater is optional, with an input PL of 82.5
Simplex operations are as follows:
Channel 8A, 159.270 MHz with a PL of 82.5
Channel 9A, 159.405 MHz with a PL of 82.5
Air Net (Interagency Ops) 159.285 MHz CSQ
***Engines and Firetowers also have the option of using Channel 1A, Simplex on 159.300 MHz with a PL of 179.9***
Forest Fire Divisions B & C communications are on their normal channels.

GM and Ed, thanks very much for the information. Are the layouts for FF Div B and C similar to A? That is, as I understand it, the day-to-day communications use 179.9 and the Ops/Tac channels use 82.5? Using PL on the repeater input -- unless the repeater retransmits the tone -- suggest one should not add the PL's to the repeater entries in a scanner and the RR db. Living on the fringe of the Pine Barrens near Brendan T Byrne State Forest, with double-digit acreage of pitch pines and hardwoods surrounding us, smoke and fire alarms attract my attention.
Yes. I also made a few minor corrections. When I read the list the first time all looked okay but just read it again, and noticed for a few frequencies I left out "TX" and also had "TX" or "RX" listed for both frequencies a few times, so I made the corrections. No actual frequency changes though. They're all okay. Just wanted to let you know in the event that you may have made a copy of it.
As of March 23rd, the New Jersey Forest Fire, Division A primary Channel 7 north repeater was being tested on a limited basis from the Division headquarters in Andover. The repeater has been set up using the antenna at that location to see if the transmit problems reoccur. Thoughts are that the problem with output power may have been due to the antenna on Milton firetower, not the amplifier board.
If all goes according to plan, the repeater will be reinstalled at the 150 foot level of a commercial communications tower located just south of Milton firetower on Bowling Green Mountain. Plans call for an environmentally controlled enclosure, new cable and new antenna. Work could begin as soon as the purchase order is generated. Stay tuned.

Today after I heard the fire towers sign on the air on channel 9 [151.265 pl 179.9] I realized I never hear anybody answer them. So I turned off the PL and I immediately started hearing Mays landing conversing with the towers. I even heard Mays Landing sign off the air at 5 pm tonight, That was a first. I have also heard Blue Anchor tower conversing with Medford and a ground unit [C-13] which was something new. What gives ? Is it possible that some units are transmitting with one PL and receiving with another PL ?
No, this was a PL of 179.9, Since I have turned off the PL I have a lot more traffic on CH 9. I especially hear the C-xxx trucks responding to fires that I didn't hear before. Don't know if it make a difference but I'm located less than a 1/2 mile from the DEP tower licensed for that frequency.
