Frequency registered to two ambulances but also Dairy Queen?

[RedPenguin]

In my county, 154.54 is registered to two ambulance companies, yet at the same time it's registered to Dairy Queen.

Why on earth would an ambulance frequency that's maybe not used a lot but important be registered to Diary Queen? I don't think the ambulance services use their radios to order at Dairy Queen. LoL.

Fast food agencies use 150MHz frequencies at low power as part of their wireless headset system. The other half of the pair is usually in the 30MHz area, for some reason. In my Canadian city, 33.4 appears to be the most popular pairing with 154.54, with 30.84 also being popular.

I find it interesting that the ambulances (if they were established after the DQ), or vice versa, was allowed that frequency. Here, the governing authority would make one or the other use a different freq.

Can anyone in-the-know explain to us why these systems use VHF-hi on one side and VHF-lo on the other?

154.540 Allocation =


154.4900 to 154.5400 MHz
Business Radio Service, 7.5 kHz spacing, odd channels at 154.5225 and 154.5400 MHz1.

The frequency allocated is for a business entity. More than likely the ambulance services with that same frequency is a private ambualance service with a regualr business license..and not a government owed organization. Government owned = City or County EMS service.

Someone has started their own EMS / Ambualnce service that they may one or all of the following = Contract out to a hospital for interhospital transfers, tranfer pateints from nursing homes to Doctor offices and other care facilitys, or tranfer hospitals for scheduled treatment ( MRI/ X-ray / Blood - lab work..and in some instances 9-1-1 emergencys ).

Some owners of ambualnce services "MAY" augment county or city ems for emergencys, and or / may have a mutual aid agreement with the local government EMS , to run 9-1-1 calls in the event of a disaster or mass casualty incident.

You have the money to start the business, meet the local and government requirements and licensing criteria, and have licensed EMT's , Paramedics or nurses....YOU can start your own ambulance business. If I were to, and it was a fairly large Metropolis/area, Critial Care Transport would be the niche. Great money..ground transport has to be used when aircraft is not avaible / weather considerations ground aircraft, and ground transport of critical care patients is almost always cheaper.

And just because this "MAY" be a business, they may have permission to have / use the local County and City EMS frequencys if they have permission and the number of vehicles/mobiles involved does not exceed the number on the FCC license.

In "Some" instances people look at a EMS "Company" as a gold pot and patient care is a low consideration. Budget is crunched to line the pockets of the owners and employee morale is not the best..therefore patient care is decreased to due the psychological stress on the EMS crews..Coupled with long hours....and not enough food during the shift. Admin folks talk/treat the crews terrible.....but the employees most always have a family..so that is why they hang around.

Then again......Most ambulance companys are surpurb...and that is the reason they do so well. They cherish the respect of the community.

The Business Radio channels can be used by any business that meets
the FCC requirements for them. Since he said that is was ambulance
companies, I take that to mean they're not guvment nor 501 (c) (3)
type voluntter outfits. Now they would also have Special Emergency
frequencies for their med use, but the business use would be on the
business frequencies. There are several catagories as I recall,
Forestry, Movie Production, Petrol, etc and all the rest not specified
are business.

One reason why CTCSS PL and DCS PL were created is to prevent interference between users on the same frequency. So, there can be many users on a single frequency.

It's probably for full duplex. Otherwise, you would need an duplexer like a repeater if both frequencies were "in band" of each other.

it would be a tossup for me.

prolly not a big deal for the Ambulances..
if they have different PL Tones,
besides they're prolly only licensed for 5 watts or so.

<edit> ERP is actually 1 Watt..
