freq

[WSCU375]

I was talking to a guy that works at motorola and ask him if a fire dept has to by a freq to use on fire grounds or training. He told me that there called interenet freq and get on google to find them, also told me that there legal to use for what ever from uniting to fire grounds, and that you just pick a pl tone cause someone like tdot might be using the same thing. Can anyone help me find this or give more information on these and how to find them. Thanks!!

Assuming you have all the frequencies programmed in here:
Jackson County, Tennessee (TN) Scanner Frequencies and Radio Frequency Reference

Try
45.3600
154.1300 (possibly digital)

Or you can try the shared frequencies listed here:
Do not program any repeater codes in until you find out what it is.
Common/Shared Scanner Frequencies and Radio Frequency Reference

Looks like Jackson Co EMS also use the State EMS channels (they are not in the county page):
155.2050
155.3400

You will probably have to be within a few miles to recieve a firegrounds frequency. A good old fashion search will turn up alot if you are within range. I have never heard of internet frequencies so I have no idea what he is talking about.

I think he meant "itinerant" frequencies. These are a few VHF and UHF frequencies that can be used anywhere in a state, or all the states. They do require an FCC license. They can be somewhat crowded with truckers, construction companies and any other user that travels over large areas. Also PL tones or DPL codes are not assigned by the FCC. They are assigned locally by the people programing the radios. I would not suggest that these itinerant frequencies be used for Public Safety (fire or police) because of the crowding they would encounter. They should apply for a frequency from the FCC that would give them some separation from other users on the same frequency.

Here is a pretty good size list of itinerant frequencies:
Frequency Reference Page

I looked in the FCC database in Jackson Co for anything matching an itinerant frequency and came up with nothing.

 

[WA0CBW]

The Frequency Reference page contains many frequencies of which only about a dozen are itinerant frequencies. The list includes commonly used frequencies, emergency frequencies and a host of other frequencies. You need to look in part 90 for itinerant frequencies. I hate it when people put stuff on the internet and it is incorrect.

There are presently only 18 frequencies in the Business/Industrial radio pool that are designated as itinerant-only.
They are listed in the table at Common Itinerant and Business - The RadioReference Wiki with note (4).

They are not the only frequencies that can be licensed for itinerant use, just the ones that can only be licensed for itinerant use.
