I assume you are talking about this system.
San Francisco, City & County of (Public Safety) Trunking System, San Francisco, California - Scanner Frequencies
and for San Mateo
San Mateo, County of (Public Safety) Trunking System, Various, California - Scanner Frequencies
If so, there are a few things to do to get this system into your scanner.
First the systems are pretty damned huge and it would be best to have
software and a subscription to the website to download what
you need.
If you decide to do this manually, you will have to compromise a little
because it would take forever to get it all.
So lets start small.
Its a
System Type: Motorola Type II SmartZone
System Voice: Analog and APCO-25 Common Air Interface
So first lets look at the control freqs. The ones in red on RR
866.22500
866.96250
Lets see if you can pick up one of these freqs by plugging one of them in manually
Press TUNE
plug in 866.225
Enter or SEL
At this point the scanner should have 4 lines of info on it. The bottom 2 will
indicate your scanner is picking up the control info. You might not be hearing
anything at all at this point. On other trunking systems(Edacs,etc) you will hear machine
code.
If all is going well, you should now press F3. The scanner will do all the work.
You will now have created a TS and one Talkgroup that has a wildcard entry.
From here on out you have to press F3 every time there is a new talkgroup.
Soon enough you will have the most commonly used Talkgroups.
You will have to enter the names for the TS and the talkgroups later. No fun at all.
If the scanner isn't picking up any control info, try the other control freq. If neither
one of these works then you have reception problems. Too far away, or you are in a faraday
cage of a building. The stock antenna isn't the best for these freqs either.
San Mateo should work out the same.
Good Luck. Soon enough this will seem not too impossible.
Enjoy
