Don and George (K2MYR), thanks for the correction. In all honesty, I
had no idea what the band limits were on the AM BC band. I thought the
top might be in the 1600s somewhere. I looked it up on the web, and it
gave me 520 to 1610 KHz. Obviously, that was old information.
Nevertheless, the out of band sigs that I was observing were above 1700.
73, Joe
