Again you ignore the obvious. This rant, that you always start, occurs 
every six months or so when you hear trash generated by ONE of the dozen 
or so JT65 rigs that operate between 1838.5 and 1840.5 EVERY NIGHT!  The 
fact that you only do this rant every six months or so, and that you are 
so obsessed by it, suggests to the most casual observer that the spurs 
are produced by some tiny fraction of JT65 operators. If this were not 
true, we would see your diatribes on this topic every week. And yet you 
continue to wring your hands, obsessing about what is essentially a non 

Let's get excited about the REAL problems -- el cheapo rigs with poor 
performance, and hams with limited technical background who don't know 
how to tell one rig from another and don't know how to set up a clean 
audio interface. You and I are both doing our best to educate hams about 
technical issues, and I see lots of good stuff on your website about the 
issue of spurious trash. We ALL should be writing to ARRL demanding that 
their "lab reports" call a spade a spade when reviewing these el cheapo 
trash generators. THAT is the real problem.
