Re: [SoCalFire] Re: [socalscan] 33.74
Yes, almost all of that sounds familiar and right on target. I'm gonna have
to print that out.
In the early 80s, before 800-MHz arrived, LAFD used the 506/507 frequencies
for fireground and Admin stuff, and for ambulance dispatch in the Metro
area; they were still on 33 MHz for Metro & Valley Fire dispath (& valley
RAs).
For years Channel 9 (33.90) was dispatch freq for the SF Valley, but they
eventually switched it to Channel 8 (33.82); I never heard a reason given,
but I remember hearing Columbus (or was it Cleveland) Ohio FD just BOOMING
in on 33.90 almost year round at different times, which may have been a big
reason.
Interesting stuff, Peter. Thanks
Harry
