G'day, Interesting conditions, or lack of, on hf. Some pretty fluttery T7 signals on 40M. A question, what is the lock-in response time of the auto notch filter. It is interesting to slide up to a BC station and hear the carrier beat note vanish. During this recent solar outburst the carrier beat note has been distinctly rough and the auto notch couldn't lock-in. Not a problem, just interest. Mike VP8NO
