You also might want to check the traditional Med Channels: 463.0000/468.0000 for Med-1 and progressing up in .025 (I believe) steps. Those are still used in many areas, but I know there were some changes in NJ. MONOC went to a much more complex system, and I'm not sure if the rest of the State followed.
Commonly, in my days in NJ, and the current practice since CMC's MEDCOMM Folded when they were bought out by MONOC, BLS does not call into ERs. They just show up unannounced. ALS Regulations (as long as they havent changed) still dictate the necessity for online medical control ie - limited standing orders with a large amount of direction provided by the ER doctor.
In a lot of places, NYC being one of them, Paramedics have been given a lot of freedom in the treatment they provide, so patient reports are a lot less detailed and occasionally not even given because the theory behind it is "the ER is going to be busy regardless, so just let them show up."
But, I digress Try the Med Channels.. that might be your best bet, or as stated above JEMS-2 155.340 is the old "HEAR" system, but its non-repeated VHF, so the range that you hear off of even a Mobile Radio might be limited.
As I mentioned above, the Meds are used very rarely by Middlesex County ALS units and I don't know when the last time was that I heard a Somerset ALS unit on them. Your best bet to hear patient reports for SPUH & RWJUH is JEMS-2, but know that still a minority of reports go over that any more.
RWJUH & SPUH are/were simplex on the Meds so you have to be pretty close to hear the actual patient report there too. They used to be set up with a mobile extender on the higher of the frequency pair but then got in the habit of having the driver do it and relay instructions to the patient care medic via SPEN-4 or citywide or some other VHF channel.
At best the MedCentral Ops channel will have a very brief note -- "let the ER know this is a Code-40," (trauma alert) or "have security meet us for an EDP." It's a good channel to have for other reasons as is Middlesex VMARS-1 -- 151.16 -- but not for patient reports.
I hope this helps? Here is information based on and from FCC license data. This information is also available in various locations here at Radio Reference.
The links go directly to the FCC site. There is a lot of frequency information here and some of it might not be what you want. However, please just be patient and slowly go through the data and there is a good chance you will find some useful data.
