Catching up with this thread...I haven't been posting here, I have been on the Vermont Scanner Yahoo Group. Just to clarify, I will repost here what I posted there, edited slightly:
I do not reside anywhere near the Burlington area, and my monitoring
happens at night or early morning when I am driving to and from work, using my
PRO106. I do not do much monitoring from home these days. Thus, I am not sure if
the observations I have made would be the same all day long, or are generally
only at night.
Within the past week or so, I have logged UVM using P25 with encryption almost
exclusively. Prior to this, I had not even logged one instance of P25, let alone
encryption. The other night I heard a couple transmissions P25 "in the clear"
(not encrypted), but otherwise it has been P25 and encrypted all the time.
I have heard SBPD almost exclusively P25 encrypted for most of the past week or
so, however the other night their dispatch was running analog in the clear,
while I believe all of the mobiles were P25 encrypted. I have never heard them
using P25 without encryption.
The UVM NAC is $656; the SBPD is $293.
Almost forgot to say, the freqs are:
460.175R for SBPD
453.050R for UVM
The other night I observed that SBPD had dispatch analog in the clear, and some
mobiles the same, however at least one mobile analog encrypted. I had only heard
the encryption used with P25 mode before this instance.
