[FedCom] In Search of the new Justice freqs...

  Hi Gang;
               San Diego seems to be one of the test beds for the new fed 
radio systems. Besides the tendency with all-digital radio's to put freqs 
right next to each other such as:
165.875   R
165.8875 R
166.875  R
166.8875 R
170.825  I
170.8375 R
170.900  I
170.9125 R
    And numerous others. I'm wondering if this is happening anywhere else, 
everything in VHF is now P25 digital except for a few Customs channels, but 
what I'm seeing is the complete restructuring of the spectrum. Freqs like 
170.8375,.9125 and .9625 were never used before, the high end of 170 was in 
.25 splits. I'm particuarily interested in 12.5 splits in the 162-164 area, 
and .25 freqs in the 166 area that used to be 12.5's (I've got a strong 
repeater on 166.6375, which means 166.625 is now probably an input. Has 
anyone found P25 in 12.5 splits from 164-164.8375, or .25 splits from 
164.875-.975?
So far I've only heard one on 164.5375, against the (old?) OCDETF freq, 
164.550. I think there's also an input on 162.4375. Weather here is on 
162.4. Also found inputs on 166.800 and .825, 164.975, and 172.000, but 
unable to confirm outputs. There are at least 4 "wide-area nets" with one 
input and as many as 10 (or more) outputs (necessary for 100% digital 
encryption in mountainous terrain.)
    172.6875 should be the input for 164.5375. Any help or additions 
appreciated...Ruff
