I was there too Mike, for way too many hours!  Up here they peaked at -10
and were usually -16 or so.  They never heard my kw+ and full size 4
square.  Same on 80m earlier.   For that area of the world, their transmit
signal was pretty weak (that night) and their rx certainly is poor.  I
thought conditions were fairly decent.
