They are transmitting in P25 mode.  I first "discovered" this when my 780 stopped on freq and I recognized the sounds as being the same as heard on Fairfax's system.  I punched the freq into the 250d and started hearing voice.  The display was/is flashing between FM and P25.  Other USSS freqs that I have are DES, but not this one.
The base (Washington) has a very bad echo on their end.
