I realize that with EMSA on the state's system, this question may be a little late in the asking. But I've never heard anything on the other 7 med channels (463.000 - 463.150). I see in the database that they are licensed for repeaters up there. Are those (or were those) repeaters used to talk to the hospitals once they were enroute? And recently, I had EMSA respond to my work. I saw them key up their radios and make a statement to a dispatcher (I think) once they were at the scene. Would this have been on the primary dispatch frequency or on a sub-channel? I really don't know how EMSA communications work. Maybe someone can enlighten me.

In Tulsa
Med 5 was dispatch
Med 4 was south of 41st hospitals
Med 3 was north of 41st hospitals
Med 1 and 2 were pretty much general usage for a wide variety of things.

When I was there we were able to transmit an "at patient" status to dispatch, I don't know if they still do this or not. This is probably what you saw them do.

I still hear the "stats" from time to time on Med 5 When I was riding with them, there was one for on-post, onscene, in service

In OKC MED 6 used to be called "HEFNER".
I used to hear them switch over to it when an EMSA unit got lost in the no-mans land of far Southeast Logan Co.
Haven't heard it in use for awhile however.

When the origional system was moved from VHF to UHF back in '83 the idea was that we would monitor the main channel all the time. When we got a call we switched to the local channel (sorta like a TAC channel) for that area.

I was stationed at #13 at Mercy and we would stay on the local channel thru till we were cleared from the hospital. We kept our GE walkies on main dispatch all the time, except when we wanted to use the vehicular repeaters function.

Somehow it evolved to what we have now...

Which is what I'm curious about. Let me state up front that I'm not real familiar w/ EMSA comms. Is it still pretty much as you described? And are the area channels repeaters or simplex only?

One primary repeater that is used for all dispatching and status. The others are like "Tac" channels but they are rarely used. Airport gets used the most for interagency between ARFF and OCFD.

Okay, I do remember reading somewhere that EMSA rarely uses radios to communicate with emergency rooms (cell phones instead). I guess that may change w/ the new digital encrypted channels on DPS. So the "tac" channels are not repeaters as listed in the database then?

I think they are repeated, but they don't keep the machines on anymore (At least in Tulsa, that's what I've heard)

All of the OKC Area EMSA repeaters were on as of not too long ago.

The hospitals are getting more use of the 800 side apparently. There appears to be a lot of traffic on the truck to hospital TG's as opposed to the earlier UHF counterparts. The problem solved by the 800 side is that the hospitals were grouped by their location in the city with multiple hospitals on one UHF repeater. There is now a separate TG for each hospital.

Our hospital is looking into the issue right now, before the new building is finished. I'm pretty sure the 155.340 will be history sooner or later. We still have our old UHF OEMS-II radio hooked up, no one to talk to... WZX965.

I have no idea what they are planning for us. DPS would be nice, but I'm hearing of a possibility of a new 800 mhz repeater for just here, possibly digital.

More info as I hear it from the boss...

The great migration to 800 mHz has begun. I am hard pressed to give you guys dates and such as we were supposed to make the shift in December-- and we now find ourselves in February....

All patient reports are being done on 800 mHz - the channels are encrypted due to HIPPA, and to allow the transmission of pt. information such as SSN, and condition- this is legally protected medical information- that is privy only to the healthcare provider.

Most hospitals catalog data according to name and Social Security #--- being able to transmit this data to the recieving facility allows them to pull up previous charts, labsm etc... prior to the arrival of a critical patient.

Which makes me wonder why the dispatch channel needs to be encrypted....
