  FBI is rapidly switching all freqs and going to the SENECA system already 
in use by the Border Patrol. Alot of the new channels are sandwiched next to 
the older ones (i.e. old .3875, new .375). They seem to have at least 2 new 
channels, with (at a minimum) 5 to 6 outputs per channel to handle the 
complexity of the encryption ensuring crystal clear comms at relatively low 
power.
Beside using the .25's instead of the 12.5's (in 167), they're also using 
12.5 splits never seen before (like 166.9125, 171.6125, etc).
They are constantly keying up so they're not hard to find, and ALL 
communication is secure, with no way to tell proximity (for anyone who think 
I'm giving something away). IRS UHF traffic has ceased, moving back to the 
VHF channels, and I highly suspect that all Justice and Treasury is 
switching to this system ensuring totally secure, numerous frequency 
communication. Ruff
