Is anyone noticing variable quality of the P25 County system. I keep all setting the same on a PSR 800 and most of the time they are perfect but sometimes without changing any thing in the radio all the transmissions are distorted. It is much easier to detect when you set up to record all night. Most nights all is good,but last night transmissions were barely understandable.. Any explanations or help would be appreciated

It is a simulcast system. When the propagation changes enough your receiver is able to hear more than one of the transmitters and is unable to process the signal properly because of the destructive interference.
It's a simulcast system...there is only one control channel and it comes from all sites at the same time. Your scanner can't manipulate a different site or CC frequency. It is what it is and you'll have to find a better spot or better antenna.
There are several channels listed that can -potentially- be the CC on the system, but there is only one actual CC in use at a time. If the system needs to change CC's because it detects interference or a channel failure, one of the other ones listed will be used in whatever order the system admin has selected.
