What I'll do is program in the reverse...511.5375 and see what happens.
I called Long Beach Transit and asked for the Radio Shop. Some fellow answered and said they send their radios out for repair...he had no idea of the frequency. I was transferred to another person and she started grilling me- I loved it! She said she couldn't give out any info. I knew that going in, but enjoy the bureau BS!!
I listened to 508.5375 on Saturday and knew it was digital. I guess I'll have to settle to listening to aviation, as all these public service entities are going to P25. In my 27 years of scanning, I never knew it would come to this. First it was trunking and now this crap. I refuse to pay the big bucks for the digital scanners, only for them to go to something else.
