Today I was listening around on 40m cw and messing with the "Shift" and Width knobs. I had the NR turned on. I was running the Shift up and down the range just casually listening to the noise pitch change. Retired people have this kind of time. I had the width down to 50 hz then I hit the FIL button to open things back up again and that's when it happened. The most horrendous blast of audio I've ever heard. My face was about 12" from the 5 x 6" speaker and it almost blew my glasses off. I have no doubt it was FULL AF gain. I jumped and nearly soiled myself. My first instinct was to quickly turn down the AF gain. I just barely turned the AF gain down and everything went back to normal. After my heart calmed down I tried to retrace my steps but have not been able to duplicate it. I guess it was a CPU glitch or something but it sure knocked a few days off my life. I had this happen to an Orion several times back before they got some of the bugs out of it. At least I could duplicate and report it but this one has me baffled.
