that has never happened to me lol, guess i'm lucky ...N1BHH said:When you are mobile, you will experience mobile flutter. Signals don't saturate the ether. You experience multipath and it always happens.

I can sit in my driveway and it will come in clear, as soon as I go 15-25mph down the road it starts.mjthomas59 said:I guess i'm not educated enough to understand that. I've personally never experienced anything like this either.
Lets get a little more detail though. Are you on the fringe of the coverage area for the system you are monitoring. We have all experienced getting out of range of a particular system we wanted to monitor and that would cause static or at the least a loss of signal. However, if it comes in clear while stationary i find it extremely hard to believe that it comes in like garbage while mobile.
What speeds are you going when it starts to lose signal? If you are driving up and down your street and having signal issues, but it comes in clear at your house, i would say there is something else going on. Kind of a long shot but you might check to make sure your scanner is getting the proper amount of power and that the power source is shielded in some way. It could be interference from the alternator/electrical system/engine while you are driving at speed.
Another kind of stupid question, but it does what you are describing, is setting your priority function to "on". This will cause chopping in the signal while it constantly checks the priority frequency while still monitoring a different frequency. This is more common on my uniden scanners(and it is extremely common on motorola radios if a priority channel is selected). Just a thought.
What kind of scanner/radio are you using
N1BHH said:I stated before and will state again, when mobile you can experience mobile flutter. I notice it all the time, the signals are constant at the transmitter, but when you are moving away, signals bounce off buildings, are absorbed and attenuated by trees and hills. Tune into a far off signal and this is what happens. Cops get it too, when they are far from where they should be, firefighters, too, everybody gets it.
Try tuning into an FM broadcaster from 50 miles away and drive around and you will experience it. It's variations come from everything around you, and because you are mobile, that just adds to all the variables you have when trying to receive. It happens in big cities. That's why public safety agencies have multiple receiver sites, to hear, and multiple transmitter sites, to cover the gaps. Some agencies can't afford all that, while some do.
