I live in Portland, Oregon. When I bought the scanner, it came with
a book that was supposed to list all the trunk frequencies for
"your" area. I don't have the book with me, it's currently with my
Brother in California, where he is using the Sacramento frequencies.
There something like thirty four frequencies for the Portland area
if I included some of the outlying areas. I entered these
frequencies in my scanner and then scanned for ID's and managed to
get enough to fill up the 50 id slots. There are a number that are
very active, and some that are virtually inactive. I would say that
at this point I have about 35 that have police type traffic, 5 that
are fire and medical, one that is used by the light rail system, and
something like nine that I haven't identified. I will probably end
up chucking those nine, if I scan and find some more id's that
appear to be active. I agree with you that even thirty five seems
like a lot of id's for police. I was hoping to get more of the local
traffic for the public works and such. I like the police, but I
REALLY like to hear the fire and medical calls.
Anything you can do is appreciated, but don't go through a lot of
trouble to do so. I should be getting on the web myself in the next
few months and I can look then too.
thanks,
Martin
