Public Safety Nationwide Common Freqs

[INDY72]

One great addition to the nationwide common page would be public safety freqs used nationwide. One primary example is the nationwide Hospital Emergency Ambulance Radio net (HEAR), and the nationwide UHF MED chans used by paramedics.

Interesting list! Like most, I'm familiar with the UHF med freqs, and the VHF nation-wide freq. But I notice you don't have the NASPAC 800 MHz freqs, and I'm not familiar with the HEAR net, or the "Federal/Non Federal Nationwide Interoperability" freqs. Can you give more details on the last two, or links that explains the who/what/when of them?

Thanks!

Here are the freqs I mentioned, in case you or others don't have them (and I guess they are called NPSPAC, not NASPAC, sorry).

800MHz

Repeater Output/Input
866.0125/821.0125 - National Calling
866.5125/821.5125 - National 1
867.0125/822.0125 - National 2
867.5125/822.5125 - National 3
868.0125/823.0125 - National 4

All agencies in Oklahoma on Motorola 800 MHz trunked radio systems agreed on the following nomenclature for the "NPSPAC" conventional mutual aid repeaters:

866.0125 - ICALL
866.5125 - ITAC 1
867.0125 - ITAC 2
867.5125 - ITAC 3
868.0125 - ITAC 4

Thanks, Jerry! I'll check them out when I get off work tonight.

Okey dokey, I hope that this helps and that this was what you were looking for.

And of the HEAR freqs, 155.160 is the designated nationwide SAR (Search and Rescue) freq.

 

[PanJurekMrJerry]

In " My Neck Of The Woods"; 5 different 'burbs got together and use it as P.D. Channel 1.

Thanks, Jerry! I'll check them out when I get off work tonight.

Interesting stuff, Jerry. The Fed stuff is nicely covered. But, Milf, I'd like to see anything you have on the HEAR freqs. If you have a link, please post it. I tried a GOOGLE, but there were so mant responses, I didn't have time to sort through them. Maybe later.

Thanks again for all the new info. This sure looks like a good idea for an addition to the site.

Sure, anytime. I think that some of the frequencies are actually shared between "U.S." and Canada especially when it come to the 220 Megacycle frequencies.
I know that most "Radio Scanning" people are familiar with the 800 I-Tac frequencies but I believe that there are also, what is known as
VTAC and UTAC frequencies which are Very High Frequency TAC and Ultra High Frequency TAC frequencies I think that their purpose is the same as I TAC.
Well I am glad that I could help you out some. Enjoy.

I am not sure when the freqs were officially designated, but as far back as I can remember these have been the official VHF Hospital Emergency Ambulance Radio Network freqs. I first found them in Police Call when I was 16, and after I became a Volunteer Firefighter/EMT years ago was told that these were the official freqs for usage by all EMS agencies for med coms, and the UHF MED chans were originally set aside for usage by paramedics only for emergency comms with Dr's at hospitals/med centers for special instructions as paramedics have much more advanced training and can do treatments under the advice of a Dr. vias radio. Over the years, I have found that of the ten UHF chans, 1-8 are still mainly paramedic/hospital comms, though 9, and 10 are now commonly used also as dispatch freqs for many EMS agencies. The VHF freqs are still all used by all hospitals nationewide as thier common HEAR chans to talk to ambulances enroute to the hospital, as well as for any EMS agency to use for thier comms regarding medical ops. After the recent FCC refarming, it will be interesting to see if these are still reserved as HEAR, and if in the future the MED chans are still reserved too. Also regarding HER nets, many states have set aside one or more as the primary HEAR net for statewide usage at all hospital ER's. In MS this is 155.3400. It is used as primary ER freq, except by a few hospitals that use other HEAR freqs for thier ops, though all ER's statewide are required to monitor State Net (155.3400) for ambulances from other districts doing transfers, and the various Helos in usage. In MS, two other HEAR chans are used for Civil Defense/Emergency Management ops statewide. These are the nationwide SAR freq of 155.1600, and 155.2800 which serves as Statwide Hospital Interop in MS. As a First Responder I have 155.3400 in my radio in case I have to transport to a hospital, and to talk to an ambulance if they cant get to my location and I need to transport to them, and to inform incomming ambulances of patient stats etc,.. on thier way to the scene. I also have 155.1600 for SAR, in addition to the EOC, VFD, and various other important freqs needed for our agency. If I can search and dig up official APCO HEAR Designations for chan numbers etc,.. I will post them here.

Here in Houston, the only FD to use the Med-Hosp freqs (UHF) is HFD (Texas). All of the surrounding VFD's do it by cell phone. Lifeflight's Disptather is at Herman, so they give patient reports over their dispatch channel along with any other Medical Helicopter in use.

 

[INDY72]

OK here is the list that I had in my old files from years ago:
APCO HEARN Designations:
155.1600 HEAR-1 Nationwide SAR/Civil Defense
155.1750 HEAR-2 EMS & Hospital Communications
155.2050 HEAR-3 EMS & Hospital Communications
155.2200 HEAR-4 EMS, Hospital Communications, and Mutual Aid
155.2350 HEAR-5 EMS & Hospital Communications
155.2650 HEAR-6 EMS & Hospital Communications
155.2800 HEAR-7 Mutual Aid, SAR, and Civil Defense
155.2950 HEAR-8 EMS & Hospital Communications
155.3250 HEAR-9 EMS & Hospital Communications
155.3400 HEAR-10 EMS & Hospital Communications
155.3550 HEAR-11 EMS & Hospital Communications
155.3850 HEAR-12 EMS & Hospital Communications

These were all designated in conjunction to many VHF Lo Band freq's. for Civil Defense, Fire, and EMS usage. They are still in use in many areas of the nation, though as mentioned with the recent FCC Refarming, changes abound. The only leftover official Lo Band designation that I still know of is the American Red Cross nationwide one.

I-tac frequencies

can anyone tell me if the I-tac 800 mhz channles are still being used in michigan
