[TenTec] Orion problems

[Steve]

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....
