Thanks. That helps a lot.
Years ago Bound Brook had major flooding from the Raritan River & they called in the NJ NG for security. They operated on channels around 57 MHz - frequencies that most conventional scanners don't cover.
The lack of activity below 63 MHz makes me even more curious about what might be going on above 63 MHz - 63.025 to 87.975. That's about another 600 channels. I would not be surprised if the military has responded to the growth of scanners & internet feeds to opt to use channels above 54 MHz. So I plan to add those additional channels starting tonight.

NJNG abandoned 41.05 and 40.10 years ago when all the helos were moved from Picatinny to Lakehurst..........like you said, mostly 242.4 now. Last time I heard anything up around 64 mhz is when the A-10s from Barnes would pop on there from time to time. I can't recall the exact 64 mhz frequency. Low band military is still very active in this area. Mostly between out-of-state helicopters flying in groups transiting through the area.
32.9, 36.9, 45.0, 51.50 just to name a few.

Any comments on the seeming lack of activity from the Warren Grove range? A typical A-10 practice mission was 286.2 for range control & FM for interplane. Nothing on Sunday or Monday but active most other days. Nothing now.
I have copied constant tones on these two channels for the past month:
288.0 S4
350.0 S2+
I do not have an audio spectrum analyzer so I can't tell whether or not these are pure tones or more complex, like data, but I hear nothing that I can recognize as modulation. These are signals & not birdies. They have different audio frequencies.
It would be interesting for others to check these out so that maybe we might determine their point of origin.

These tones are on all the time. Different audio frequencies. Signal strengths the same. I have to squelch out the 288.0 tone so the radio doesn't stop on it every 11 seconds. Unfortunately that keeps me from hearing weak signals on other channels.
Picked up a WX satellite on 137.9125. Repeating fax-like tones.
1723Z 131.825 UnIDed aircraft to CP ref passengers. I have this as Dover AFB. Interesting to hear the AF on an ARINC channel.
