Points well made.  Ruff frequently posts such information and for many
reason, not just in this context, I have great respect for him.  Thanks for
responding.

Hello Arthur BEP:

Just because a signal is encrypted doesn't mean it can't give some vitial
information, especially from the input (or posible search range of)
frequencies are monitored. e.g. Technical savvy hobbyists might get a good
idea how close the feds were to their monitoring location.

In the book "Family of Traitors" (John Walker navy communications officer
traitor) it mentions that the KGB would monitor the FBI's Washington DC
radio systems and if encryption traffic increased they would cancel
Walker's drop of classified information to them.  It may also be a "tip
off" to the hobbyist to monitor the state/county/local law enforcement
frequencies carefully because a major enforcement action may be at hand.
Also depending upon the encrypted frequencies normal designated usage it
might be time to evacuate the family/loved ones out of the area!!!!

Currently many of the federal law enforcement agencies are using NEXTEL
(FBI has a very large contract with this vendor, and there a few more
single agency contracts, as well as a general GSA schedule contractor for
all other federal agencies) and/or other digital cellular/pcs phones for
investigations/ "strike" team recall/formation coordination of activites,
etc. rather than radio systems SO signals are buried among all the users of
the sytems making this type of analysis useless.  HOWEVER, it does appear
that during the "take down"/arrest phase of the operation, the feds
continue to use low power w/t's on their radio systems, in many cases not
encrypted.  I know that both TLC/Discovery networks as well as a book
(can't recall the name) showed the US Marshal Service making extensive use
of digital cellular/pcs phones in lieu of their radio systems; BUT during
arrest ops the portables came out.

Also sometimes encryption won't work with all the participants in the radio
system, so depending upon the urgency of the operations they make go in the
clear or even some participants transmissions will be encrypted while
others won't.

Those folks that spend their valuable time really doing tedious analysis on
this encrypted activity really are contributing to this list!!!  Don't
discount how valuable this information may become to you in the future!!!!
