I spent  three days chasing them on 160 and finally connected this morning 
(Sunday)  at 1204Z.  There was huge QSB and was very frustrating to hear 
them on  
a peak answering guys over and over with no response. But they were up  
against 
local noise.

>From their website: "The big Marshall Island  Resort allowed us to install 
all 9 
antennas from 160 to 6 m. The 80- and  160 m Verticals are 50 m away on a 
platform direct at the lagoon. All  antennas have a good SWR but the 
problem is a 
high man made noise from the  hotel area. May be from hundreds of air 
conditions, 
pump stations, beach  lights and other things. That means we are hearing 
not good 
and are not  happy about so many signals just in the noise. That means your 
signal must  be over this noise. The noise level from 160 to 30 m is never 
better 
than  S5 noise, on 80 m extremely bad with constant S8. Any receiving 
antennas  
sets could not improve the receiving situation – always the same noise.  
Anyway, 
we continue operating the low bands and try our best to get you  all in our 
log!"

My antenna BTW is an inverted V, up only 45' at the  apex with the ends 
tied off 
to Palo Verde trees about 4' above  ground.  I suspect some vertical 
radiation 
from the coax as the  common mode choke impedance is negligible at 160. 
Using my 
"old" K3 and  KPA500.  There were a few more static crashes than two days 
ago 
when  my noise was unbelievably low for 160.  Never heard it so  quiet.
