OK, luck ran out. No more receive for some reason. I had it running and
came in from the shop all happy and proud and when I went back out about
45 minutes later it had stopped receiving and I have not made it receive
since. BUT, I did find a guy who has a spare Logic board that he is
sending me. It is in unknown condition so it may be no better....
