I've been listening to the T I 9 operating on the various bands and the 
first day they were ashore, is the worst jamming on the DX transmitting 
frequency I think I've ever heard.  I'm not counting all the hundreds of 
guys that forget to switch to a split frequency mode but I'm referring to 
all the carriers, zero beat carriers, and what we used to call quarm as in 
QRM.  I think it was the first day of island operating I heard the jamming 
on 17 meters but when he switched to 40 meters that night, the same thing 
happened on that band.  I was glad I didn't need to work him since I've 
worked a half a dozen Cocos Island operations over the last 40 years plus 
but the pile ups, as I tuned through all the calling stations I could hear, 
really spread out across the bands.  It reminded me of the hk0tu operation 
from Malpelo.  The second operation from there I heard and worked was run by 
the HK boys alone, as I recall, and on both phone and CW, they said they 
were listening from 14200 to 14275.  Man, what a mess that turned out to be. 
Of course, this was when Americans couldn't go below 14200 so the band was 
smaller.  CW was just as bad because they had them spread out all over the 
band.  The HK operators would work one station and then quickly tune up the 
band.  Guys kept moving across the band, dropping in just atop the current 
station being worked in hopes they be next in line.  The old pile up just 
got bigger and wider.  Fortunately, I think they stayed for two weeks or 
maybe it was ten days.
