When a medevac, for example, Hackensack-1 switches to "Air Comm" is this a talkgroup on the NJSP system, or another frequency, or is this referring to the air band frequencies used by aircraft?
Chris- I think speaking for a lot of us here- we are perpetually interested in the medical helicopters. Some might not realize that the helicopters flown by the nearby hospital (etc), are not owned by that hospital or group. As you stated Air Methods is one company that does operate helicopters for hospitals and others.
Not knowing the details of their comm system I assume from your post the following: that Air Methods must have an extensive national communications system to keep in touch with all the aircraft nation wide?! So speaking specifically about Hackensack- as an example, they are switching over to a UHF conventional repeater to contact back to the corporate base? I would assume this is of course "wire lined" back to the mid-west base in Omaha? If you can clarify or add any other details, please do.
Once they are back in NJ, Hackensack 1 will switch back over to 478.2375 pl 131.8 to communicate with MICCOM and the north aviation talkgroup to communicate with REMCS. .
123.100 NYPD Aviation (NYPD Only)
tony, great list !. just with regard to (NYPD only), this fq. is a nationwide common for search and rescue operations <sar>. however, this is the best frequency to hear nypd pilots order their dinner. LOL !.
I also have 123.100 also listed as US Coast Guard and Civil Air Patrol.
123.025 is also assigned by the FAA for Chopper and medivac choppers. (It was also heavily used in Baltimore for chopper to chopper comms during the recent riots according to their forum)
I have 123.050 as the Wall Street Heliport and 123.075 as the 34th Street Heliport.
122.900 has been used by Coast Guard, Newark Heliport, and was at least at one point the National Hi Jack negotiation channel
I have 127.850 listed as Newark PD Choppers (not sure how accurate that is)
123.000 - Linden Airport Tower
