Maybe!Is that the GPS from "mancow"?
Oh, I was able to generate a high pitched whine from the radio today. I made some changes to the display settings and some systems in Sentinel. I grabbed a random SD card from my stash and loaded the data onto it. I stuffed that into the radio in my truck and turned on the scanner. While the FLs were loading, I heard a high pitched, but very, very faint whine. In fact, if my ear wasn't within about six inches of the external speaker, I wouldn't have heard it at all. It was there, even more faintly, while the scanner was scanning, but not receiving any signals.
There is no way I could hear it when the engine was running.
When I get a chance, I'm going to swap the original card back in and listen for the whine.
It seems that it might be SD card or maybe processor related. It's no where near as loud as some people have complained about.
