Blue blues
Tracy,
Yes, I know that info. I've used your site frequently, BTW and have found it very useful.
In any case, I read in a thread some while back (a year or so, I think) that the old Orange County Black channel (from pre-trunking days) had been recycled and is now the Blue channel. But I have not been able to find any further info on it since such as tones and repeater usage, etc. As interesting as LA and Van Nuys airports may be they come in rather scratchy here and aren't really what I want to listen to so if OC has a tone for this frequency I would REALLY like to know what it is. So far, I haven't heard any apparent OC traffic on "Blue" so I haven't been able to capture the tone from an OC transmitter. At a guess - OC seems to use 156.7Hz as a common CTCSS tone for many of their conventional frequencies so maybe that is what they use on "Blue" as well?
