[CQ-Contest] Coax Stubs for SO2R

[Bill Hider]

Mike, quick comment on harmonic "tone".

I have heard many hundreds of times my CW harmonics on my receivers.
The tone is often buzzy, raspy, and/or otherwise distorted. Sometimes it's
pure.
If I were you, ignore the tone.  That's not the problem.
Take a break.  Let us know when we can help again.

73,

Bill N3RR

Hi Bill & many others, Kimo, Dave, Jim,  Peter, Gary, Gerry....I've
forgotten a few.

You are all very helpful and I am trying to wrap my head around this.

I think I have to start from scratch and remove everything from in line from
the transmitter. \

I did measure with the T in line and also the coax switches (I say switches
as one is a coax switch, and one is Teed off to potentially just switch
stubs) Tonight I took all that switching out of line and no change. (knowing
full well my stub is no longer perfectly resonant as I lost perhaps 4" of
extra line when I removed the T and the stub-switch, but I still should've
been in the ballpark) No change.

I can't help but wonder by what some of you are saying that I am getting
rectification or bleedthrough inside the shack itself somehow.

I don't have time tonight to try anything more.  Been at it ~4 hours and
have other stuff to do now.

Wednesday or Thursday I am going to connect the transmitter directly to the
antenna (remove amps, switches, tuners, etc. and try again.) (my receiver,
or radio B in my SO2R setup is already direct to a multiband dipole)

On harmonics...should they sound more or less pure, or no? (or is that like
a "how long is a piece of string" type of question ?) Mind are pretty much
bang on frequency but real growly....not pure at all. (either on the IC-7410
or IC-746)......

One time I recorded VE9HF some 8-10kms away running QRO on 14MHz and his 10m
harmonic was a pure signal.   He even had some callers on 10m !

Dit dit & tnx agn.  Very much appreciate the great help !
