[FedCom] What can we actually monitor?

[Arthur-Bryan E. Phelps]

I know I'm really trying your patience, but, excluding the USSS, do the ATF,
FBI, FEMA and US Marshall communicate "in the clear?" I just read in Monitoring
Times where someone was monitoring the US Marshall Services,on frequencies I
was told were useless. Then their is FEMA.  Police Call 2002 has their common
frequencies published.  Why publish them if they don't communicate in the clear?
 Granted you can argue thay MilAir frequencies are published and that is correct.
 On some of those frequencies, however, some comms are encrypted, others in
the clear.  Then not but not least the elusive FBI ... I get e-mail from folks
who say they hear them and other folks who basically tell me they are impossible
to monitor.  Our state police radios have the FBI frequency 167.5625 programmed
in their radios.  I've never heard them communicate with each other, but....?
 Some of you do credit to this hobby and provide a service to all of us through
your tireless efforts in seeking out these frequencies.  You know who you are
and I truly thank you.  I don't have your patience.  You might actually be the
folks that can give me some straight answers. Does anyone hear anything in the
clear on the following?:     163.1000        167.9       FBI/DOE Common    
   12.5
170.0250        167.9       FED GOV Common        12.5
169.7500        167.9       FED GOV Common        12.5
165.2875        103.5       ATF Common            12.5
