During CQ160m SSB last year I was called twice within minutes that my
harmonic did strong interfere to the dx portion of 80m on 3794kHz while I
started running on 1897kHz.
One caller was 80km away from me and reported S6, the other 30km away
reported S8 for my signal on 80m.
My inverted L was pulled up my 80m vertical, so probably the harmonic was
just coupled into the 80m antenna.

But it's sure funny that ONLY the operators on 3655 have actively complained
about 2nd harmonics.
If the problem was on the transmitter end of the folks on 160, wouldn't it
stand to reason that you'd see 2nd harmonic problems on every one of their
transmissions, up and down the band? Wouldn't there be 2nd harmonic
complaints from operators on 3600 to 3800 kHz? Wouldn't we be hearing from
all the other nets (and alleged nets and ragchew circles and curmudgeons and
lord knows what else) operating in that frequency spectrum?
Isn't it exceedingly odd that the transmitters only have an alleged 2nd
harmonic problem when they're on 1827.5 kHz? That the complaints target
specific people, and that they got posted to the web site within 24 hours of
the end of the contest?
I'm not making excuses for anyone, nor am I ruling out the possibility that
in at least some of the cases, there MAY have been a problem on the
transmitter end -- an allegation that would need supporting evidence before
I call it a hypothesis.
But without evidence to the contrary, frankly, the allegations don't hold
up.
And while I'm thinking of it... why are we (or at least some of us) making
excuses for the anti-contest bunch? Why are their complaints -- with no
evidence (time? day? exact frequency? who was being called by the alleged
interfering station?) being accepted at face value, yet the contesters who
have been smeared on that web site are the ones who have to face the music
and defend themselves?

Ron,
If someone in the midwest will put their SDR with Skimmer on 3650, covering
plus/minus about 48 Khz from that frequency during the CQ 160M Contest,
everyone will be able to see the results - a nice list of who have a second
harmonic that can be heard, when it was heard, and how loud it was relative
to the noise on the receiver end.
Although my interests are clear, consider the following. Let's say there
was an amateur band that went from 900 - 925 Khz and there were those who
operated that band who could be heard with pretty strong signals on 1800 -
1850. Those who are topband enthusiasts would be REALLY, REALLY upset. Not
a lot of difference except I doubt these guys have any problems copying each
other through the second harmonics that happen to land on top of them.
I would be more likely to buy into a notion of a problem being on the
receive end or out of the control of the transmitting guy if they were not
exactly double the fundamental frequency and and heard by many people. It
is not just a couple of guys who have heard some pretty strong signals
propagated for over a thousand miles. It is many.
Stan, K5GO
