Here in the S F Bay Area I have been monitoring what sounds like federal agents on a trunked DMR business system. They don't sound like local law enforcement (no use of codes, not familiar with suspects, local streets, etc). I have listened to a lot of FBI surveillance over the years (when talking in the clear, of course) and this is what these guys sound like. They did make one reference to "the district on the other channel". The current surveillance I"m listening to seems to be drug related...so maybe DEA. Talk now about a warrant for a tracker and assembling a complete team later to do "take aways". They probably think their system is secure, and was pretty much, until Whistler came out with the TRX 1 & 2. Any thoughts?
