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.
