The denouement to the story: I wrote to Elecraft and purchased P/N
E850552, the KX3 Antenna Connector Assembly w/LPF. It arrived today.
After the cub scout meeting tonight (my son went from Webelos to the local
scout pack in the crossover ceremony tonight) I spent the last 20 minutes

Thanks Don; I remember that we went over this earlier in the thread.
Highly unlikely that I had legacy stuff as I became a ham in 2015 and
acquired most of my stuff new.
I am inclined to think that it was more possibly an out of spec 50 ohm
connector or a manufacturing defect. I've already worke
Rich,
Since you have traced the problem to the contact between the female BNC
and the male (yes your twisting and applying pressure confirms that is
the problem).
It is entirely possible that if you had some old cables made with old 75
ohm BNC male connectors, that they could have enlarged t
Unfortunately there are some really crappy (cheap) BNC connectors out there,
some with too large centre pins. Using one of those even once may be enought
to damage the female side :-(
So when you get a new female for your KX3, have a look at all your cables and
adapters and make sure all of them
I've pretty much exhausted most of the permutations of my cables and
connectors. The only persistent behavior is that if I apply slight
pressure to the side of the BNC connector where it plugs into the jack on
the KX3, or sometimes if I twist it and then apply slight pressure just so,
I see a jump
I use many BNC connectors, some at KW level, and nearly all of them are good.
But occasionally some do not make a good contact and need to be thrown away
ASAP. The best way to check is to try another cable.
Recently I bought a large number of cheap RG-58 cables with BNC connectors
from showmecabl
That's one thing I was able to check; connector is tightened securely on
the shell of the KX3. Thanks.

Rich,
If the BNC connector rotates even a wee bit, that is the problem -
tighten the BNC jack. A good connection to the jack shell is required.
"Opening it up" is not a big deal - unless you have the 2 meter option -
just remove the bottom cover, no more complicated than changing batteries.
I have three more days of checking various configurations including binding
post antennas, end fed half waves, opening the damn thing up... Thanks
all for the suggestions.

Open it up and make sure that the antenna connector is securely connected to
the ATU board.

So was the antenna and related cabling/connectors good as verified by your
analyzer at the point of the radio connection? In some 60 years of doing this,
I have yet to find the radio to be the problem when it tells me it’s looking
into high SWR. There’s a first time for everything, course :-)
Okay, so I took the plunge and disconnected the KX3 to take with me on
vacation. Hooking it back up proved to be a tad problematic - SWRs of
25:1 and no signals from any bands, anywhere. I'm now working through what
options I have, starting with checking female connector deformation and

Sometimes the center pin of the male BNC will get pushed back into the
Teflon insulator. Run your thumb nail over the end of the connector. Your
nail should touch the end of the pin.

Hi,
I had an oddity with hooking an antenna to the BNC connector on my KX3 that
happened enough times to be chalked up to something other than random
chance.Looking for opinions on whether my solution aligned to your
experience(s).
I have a complete station - a KX3, a PX3, and a KXPA100. Th
