do they use these frequency
The Manual that I have for IHERN from the 1970's on file shows 155.340 as IHERN and 155.280 as a backup frequency across the state. Both frequencies were in the base radios at the hospitals across the state.
Yep, each state had/has its own slightly differing listings of the nationwide HEAR Net freqs with sometimes a differing tone in use at every single hospital for each freq. For example, we still have a long listing of differing tones in the IN statewide listings... Whereas in AR, the statewide tone is 131.8 PL, and it has multiple tones in MS... IHERN is still primary 155.3400 for hospitals here in IN, with this being patched into almost every TRS in use to an HEAR, or MED, or ER TG for the facilities on the TRS's. You can still monitor traffic on it but its rarer, and harder to copy the ambulances at a distance on the old conventional channel, where as on the TG's on TRS's, you get both sides of the convos... Where encryption isn't in use of course.
(I still remember when the VFD I was with switched out some old radios with "dial a tone" wheels, for digital display push a button keypad radios in the rescue units, and it made it so much easier to interop with the area ER's and EMS units. Hold down finger for a second or two compared to manually scrollling to the tone, and hoping you didn't click in the wrong one lol... So much better when your display reads HWMH ER, KDH ER, UMC ER, than the old way.)
