Unknown EDACS Control Frequency in the military band 138.51?

[slalomkayaker1]

Does anyone know what EDACS system frequency 138.51 or 138.515 serves?? The signal is powerful in potomac,md. Could this be the David Taylor navy research center???

Much thanks to anyone who knows

Possibly part of the Naval District of Washington VHF EDACS system?

Nope its not part of the system

Nope its not part of the system because i checked other web sites that have the system and this freq is not listed.

Ok, my thought was maybe they added frequecies or sites at some point. Keep us posted if you find out any additional.

 

[slalomkayaker1]

Do you know a good site for FCC data?

Would you know a good site with FCC data??

 

[RFfreeTLD]

Other than the FCC?

One for public access to federal frequencies does not exist in this case.

Oh thats 2 bad

Oh thats 2 bad. Am I correct that Its fairly impossible to track an EDACS system with only the control channel, unlike motorola systems.

 

[RFfreeTLD]

Correct. Do keep an ear out to see if that control channel rotates to other frequencies as that may narrow down the initial search. Also, the use of the ETrunk program can be helpful in IDing new LCNs.

Some USN aircraft carriers use EDACS with Aegis. Any large vessels in port?

You may be receiving the NDW's Naval Academy (Annapolis) site control channel. I recall picking up another EDACS control channel in the military VHF-high band (while listening in Montgomery County) but I was not able to confirm its use.

I know there are two or three Navy VHF EDACS systems in the Washington area. And I've heard that the Naval Academy may be using one of them. However, I believe 138.51/138.515 is fairly strong in the immediate DC area. This would seem to indicate that this control channel does not belong to the Naval Academy. Or maybe they just run a very strong system.

You might ask this question on the Scan DC list at qth.net.

Who is capable of reciving this system??

I am capable of recieving this system but i do not have a cable to monitor control channel with eTrunk. Does anyone have a cable and eTrunk so they can get the ids of the system and post them?

you might want to try the frequency of 138.5125. that part of the spectrum goes in either 12.5 or 25 khz steps. depending on what is using them at the time, being military aircraft or military bases. 8)

The Control Frequency

The control freqeuncy i believe switch to 138.39 on saturday and voice can be heard on 138.51

think its the new EDACS Digitl TRS eather used at Andrewa A.F.B.(Comes in strong near there) or Boling A.F.B.

 

[Guest]

Oh yea, by the way the new EDACS DIGITAL RS types CANT BE TRACKED as far as I know, WITH ANY DIGITAL SCANNER.
