         Excellent point!  I have not read ARRL's document but am surprised
they would not mention this.  When I can hear a 20 uW signal on 160 from
275 miles away, and 100 mW on 10 meters from Europe, why would I not
expect to hear the accumulated noise of thousands of BPL sources from
a skip zone with propagation?  Seems to me like it would simply raise the
noise floor when that happened.  This might be worth mentioning as a Reply
Comment which is now possible even if you did not comment in the original
Comment period.
