Adding mini-banana jack counterpoise point to a KX3?

One of the things I really like about the KX2 is the hole for a mini-banana
jack counterpoise connection. Is there any place that could be added on a
KX3? The case thumbscrews get cranky at times.

Adding two flat washers under the knurled screw heads would likely help.

Ken,

I don't know about mounting a mini-banana jack, but you could look at
the left end of the heatsink (heatsink facing you) for a good grounding
point other than the thumbscrews.

Installing a mini-banana jack would involve drilling holes in the case.
There is not a lot of free space to do that. Pick your mounting
location carefully before drilling to be sure it will not interfere with
anything in the KX3.

I have a little pigtail with a PowerPole connector on it. Folds nicely out
of the way.

When I want to run that sort of portable setup, I simply plug a BNC male
to Pomona (double banana) adapter onto the KX3 output.

The BNC-BP adapter is also available from Elecraft. It's under KX3 accessories on the order page at $9.95.

Re: Adding mini-banana jack counterpoise point to a KX3?

The double binding post adapter isn’t what I have in mind - I’m thinking
specifically about use with the AX1 which needs a counterpoise.

Rich Hurd WC3T, where are you attaching your pigtail?

Re: Adding mini-banana jack counterpoise point to a KX3?

Currently to one of the case screws with a ring terminal. When the AXT1
shows up, I'm going to create a pigtail from that antenna mount
specifically using a .183 quick connect and a PowerPole (or maybe just a
quick connect to the counterpoise wire like the Superantenna does.
