I've seen a few folks log this as a Range Control frequency. kkn50 has logged it quite a few times as well.

I'm catching range control on this frequency into South Texas today.. heard a range control weather report that reported "95.6 degrees"

Preliminary searches on the Internet show this to be an alternate range control frequency for Camp Gruber, OK which would match up nicely based on propagation in S Texas. Temps in the area reported by the NWS match right up into the mid 90's.

Is it possible this is now a primary range control frequency for Camp Gruber in OK?

Any ideas?

(I love identifying US MIL operations in the low band... fun stuff!)

Possibly Red River Army Depot.

Weather report ; Likely = Ft.Hood. If you caught the time I might be more helpful. This time of the year , publishing the " Wetbulb" / temperature , on the net is probably a regular occurance. Range Control would publish over the air ; the temperature / wetbulb , so troops in the field ( camping - bivouac / firing ranges - exercise - manuvers ) can adapt their uniform in accordance with policys.

Information to help Military Commanders make decisions about operations in the field as far as hydration / work & rest schedule...and again uniforms ( taking off outer military shirts , unblousing the pants = take pants legs out of boots ). Medical personnel have methods for determining the temperature and " wetbulb " . Wet-bulb temperature - Wikipedia, the free encyclopedia

Updates for the weather in certain conditions ( extreme heat and cold ) are usually published every
forty-five minutes or hour. Usually forty five minutes , so the informaiton can be deseminated in proper
time.

Also consider low band Military air. Aircraft receiving , or passing along the weather.

There is also Camp Maxey National Guard training center north of Paris. I have not seen anything listed for it.

Almost certainly not Ft. Hood - their range control is 30.45 and pretty well known, and propagation wouldn't favor Ft. Hood.

It's definitely a range control base station and has been logged as such quite a bit. Red River Depot doesn't have an active range that I am aware of.

Not the Range Control you are hearing but the "Tango 99 Romeo" net that was active on 31.200 in June was local. From the consistent signal strengths and concurrent activity on other frequencies I think it was training at Camp Bullis.

I've seen a few folks log this as a Range Control frequency.

I have logged 31.300 several times: Range Control - Oklahoma National Guard Camp Gruber Maneuver Training Center, 14 miles southeast of Muskogee.

Thanks kkn50, we'll get this into the database. I think my original post might have been a typo.

"Tango 99 Romeo" would be for comms on the entire " Net ".

Example. If all the call signs for a particular unit began with "Tango" , each different "User" has a numbered call sign. Such as Tango zero-six , Tango four-seven , Tango Eight - three ,ect ,ect.

If you wanted to talk to everyone in the net , such as to obtain apersonnel count , ** A message for the entire net ** ; then you would broadcast the phonetic word ( alpha to xray ) then the number(s) followed by another phonetic word. Another example = " Tango Seven Bravo. This is Tango Nine - One...radio check , Over." Then the "Net" gives the NCS ( Net Control Station ) an answer...In numberical order. The NCS acknowledges the radio checks with " Tango Seven Bravo , this is Tango Nine-One..Roger , OUT !

I will not get into detail here on the net ; but in peace time , Net Freqs change ; with the exception of dedicated freqs such as " Dust Off " Medivac , and Range Control.

The military has standards for low band frequency change in peace time , as well as under combat situations. Encryption , I will not even get into here on the boards.

CEOI ( Communications Electronics Operating Instructions ) books list unit identifiers , freqs , and other material. It is classified as "Secret". You don't have to have a security clearance to talk on radios ; but a security clearance to use the book , and a " Need to know".

The freq you descibed , could be , a dedicated training frequency also. Or it is an issued frequency to a particular unit.

I know you mean well, but dude, you're kind of a mess, and I'm staging an 'intervention' here.

CEOI was changed to SOI years ago. Besides that, I'm glad I've got a big bucket of Thai food to go eat right now instead of trying to address all your misinformation and "I could tell you, but then I'd have to kill you!" junk.

Here's a decent, basic resource for understanding some military combat net radio (30-88MHz) stuff:
