The mobiles typically sound better to me than the base on the base channel.Passed a North Sac CHP officer today on a traffic stop and pulled over in a nearby parking lot to monitor the extender for a while and noticed how much different the base traffic sounded vs the mobile traffic.
I am picking it all up. Sometimes I pick up the mobile on the mobile frequency and sometimes on the base frequency (yes I still monitor both) and sometimes either/both. What continues to amaze me is how much better the mobiles sound now. Dispatch varies depending on the specific repeater site being used, channel, time of day, etc.I am still not picking up any of the mobile traffic on the base frequency though, I can hear dispatch but not hearing mobiles. I'm going to need to do some tweaking on my CHP antennas, my guess is I'm not getting traffic from the site the mobiles are being repeated on.
You must get good reception of the site being used to repeat the mobiles. I'm guessing they are using Pine Hill or Pilot Peak.What continues to amaze me is how much better the mobiles sound now. Dispatch varies depending on the specific repeater site being used, channel, time of day, etc.
That would explain why I can't hear them from my home in South Natomas. I was over at my mothers home in Citrus Heights last night reprogramming her scanners with the new frequencies and could hear everything.I believe Pine Hill is for the Val-Black2
Pilot Peak is the Val-Gold2..
Val-Green2 is on Pine hill also
You mean the amount of traffic you have been missing!I was absolutely amazed at the amount of CHP traffic now that the mobiles are being repeated, now we know how much mobile traffic we have been missing in the past.
So just using GREEN as an example; if I understand what is happening correctly, it goes like this. Please correct me if I am incorrect.GREEN

I can attest to that, at least as of last week, as I am picking up mobiles on a mobile freq (directly) and not a base freq.Avtar can correct me, but I think they use receive voting but NOT simulcasting in some areas of Valley Division.
Two thoughts here:When a mobile calls in on the mobile (Car-to-Station) 42 Mhz frequency, this is picked up by multiple sites. The receiver-voting system automatically determines which site received the mobile the strongest and automatically sets up the console so the dispatcher can call them back on the 45 Mhz base frequency from THAT site. (Or they could select a different Tx site manually.)
I am sure I am picking up all the sites for Gold2 and Black2. There might be one for Green2 I don't receive, but I am mindful of which channel I am receiving on, and I am "close enough" to hear the mobile directly.In your example, my guess is that you were close enough to the officer that the Tx site dispatch chose to call them back was within your receive range, but the "central" site that was repeating the mobiles was too far away.
That makes no sense to me unless I am close to the mobile and down in a hole. If the mobile radio can reach the repeat site, so can I.If you were even closer to the officer, I'm sure there are situations where you could receive dispatch on the Base frequency (from a close selected Tx site), receive the officer on the Mobile frequency but NOT receive the repeated mobile traffic (because the centrally chosen site was too far away).
