    We've noticed a huge increase in rants and negative posts that revolve around agencies going to encryption due to the broadcasting of scanner audio on the internet. It's now worn out and continues to be the same recycled rants. These rants hijack the threads and derail the conversation. They no longer have a place anywhere on this forum other than in the designated threads in the Rants forum in the Tavern.

    If you violate these guidelines your post will be deleted without notice and an infraction will be issued. We are not against discussion of this issue. You just need to do it in the right place. For example:

Well, a couple of questions to ponder:

  1. Where is the receiver you are using?
  2. Where is the transmitter for 153.770 now (post reconfiguration)?
  3. Where is the transmitter for 155.940?

2.There is no license info for 153.770 in RR, however 155.940 is modesto's old dispatch channel and originates from MFD sta#5...

KMG969, 153.7700:

Transmitter 1 is 280 watts ERP, 11 miles west of Patterson (Mt. Oso).
Transmitter 2 is 20 watts ERP in Angeles Camp with antennas aimed SSW (208 degrees).

My guess is you are hearing Transmitter 2, but I could be wrong ...

I use the Mt Oso 927 ham repeater from Livermore in my car, so it could be the site.

I am noticing no difference here in Merced County. 153.770 is the all county dispatch channel.

I also get the Modesto County Cmd 5 channel here in Merced Co on my hight level antenna system as I always have. This is a Modesto City channel that goes to the Modesto dispatchers rather than the Stan Co Fire dispatchers from what I can tell. Modesto incidents also use the Modesto tac channels. I would presume that this system allows Modesto to expand as a need might require to the county channels. We have that ability in Merced ****y should the need ever arise.

You will see the Turlock channel use as tac in areas other than Turlock, as it is also used as a bridged channel to the Turlock Fire 800 system. I do not know how the licensing is on that channel - if it' by agreement alone or is Stan Co added it to their compliment of licenses. With agreements in place, neighboring agencies can use their neighbor's frequency, but that is not the norm.

Reflection on low signal - maybe someone is pressing the wrong transmitter button? Or some other technical issue? Maybe they are narrowbanding, where levels are sometimes much more noticeable if misconfigured.

Well I've got a vhf yagi i could always pull out and point southeast. I'm assuming that would fix the issue with 5db gain...
