When I get time I'll have to look at this. I have an old K3 with the original
synthesizer and no TCXO and a new K3S with a TCXO.
I also now have a GPSDO. After getting this, I checked the K3S and was not
thrilled to see that the TCXO required a 20 Hz adjustment.

Not to worry, my K3S does it too :-(

I don't use JT modes, but on RTTY and PSK I've found a similar issue with my
K3S. I've mentioned it here in the past more in reference to the built-in sound
card super sensitivity affecting VOX setup. The best I've done is to go into

Look into Ecoflex. http://www.vibroplex.com/contents/en-us/d39.html
I'm using it from the gear in the shack through the wall --> Andrew Heliax to

So far, so good.
I measured some Buryflex years ago for a friend who had 100' dropped shipped to

I don't think you're an idiot. I've reported a few defects to Elecraft over the
last 8 years. Usually they get fixed and are sometimes folded into production.
There are thousands of guys using K3s that include a fix that was developed
using my radio as a prototype after I demonstrated it to a
10.118283 in Tucson. Peaking at S9 with QSB to S6.

Bob,
It appears that you're of a mind that the winding (coax) is tightly wound around
the core. That's not how some guys are doing it. It's just loosely looped
through the core. See fig. 36 in Jim's paper.

If you're driving a 50 ohm load, then the cable wound around the core is just an
extension of the transmission line and has no impedance modifying effects.
The significant parameter is the common mode (CM) impedance. G3TXQ discusses a
way to measure it here: http://www.karinya.net/g3txq/chokes/

Not to put too fine of a point on it but strictly speaking, that is incorrect.
The characteristics of a pulse that can be blanked are:
1) its amplitude is sufficiently greater than the desired signal so it can be
detected as undesired (noise)
2) its duration isn't so long that the "hole" punc

You mean like that "sneak ground" from the input of the tuner back to the
grounded amp or exciter? Or are they floating too?
