  Thank's to Jeff's post(s) yesterday (12-16-04) I was alerted to the 
Dahlgren's freqs & comm's.
I entered the freqs that he & I came upon into my 2052 since it has 
trunking abilities.Unfortunately the 2052 does not have PL tone id option.

  One thing I noticed pretty quick was that the "data" freq kept 
changing,almost hourly.I do not have alot of experience re trunking but it 
seemed to me that,in the past,the data freq usually stayed fairly constant 
for around 24hrs & then changed freqs.

  Maybe they are in the progress of setting up a new system?I also noticed 
that when a freq was not serving as a data channel,it was simulcast.

I don't know if these freqs,Dahlgren/AP Hill, have been posted so if they 
have sorry for rehash.
