KX3 Upgrades

Which will come first the KX3 2 meter board or the 100W amp?

Direct from one of the Elecraft Twins: "We prioritized the amp ahead of it
(same engineer on both projects).

I'm guessing we'll be field-testing 2-meter modules around Dayton, assuming
all goes well. (Did I mention this thing is incredibly small?)

Hmm, I'm the twin who signs the checks..

Based on the frequent times I'm addressed as 'Wayne' and Wayne is
addressed as 'Eric' at shows, we're totally confused on the twin issue. ;-)

ID Hint - I have a little less hair..

KX3 ATU goes off/on during send?

In reply to this post by Richard Thorpe-2

During ARRL-DX - running 5 watts - I noticed a faint click in the KX3,
occassionally. I tried to reproduce but couldn't. Later I noticed the
ATU-sign was blinking briefly after the click.
I checked SWR, but KX3 says 1:1, and a quick ATU- tune confirms the 1:1.
I'm a alarmed now - I don't want to see my ATU in smoke. But I don't
have a fix or workaround yet.
Anybody else experienced this problem?
tnx es 73

Re: KX3 ATU goes off/on during send?

Gernot,

Your KX3 might be behaving correctly.

E.g., when tuning across a band edge, the KXAT3 is designed to automatically change to the last tuning of the new band. This is a feature, to save the battery (don't need to retune just to change bands, if you've already auto tuned on the new band), and to not clutter the spectrum with auto tuner QRM.

If you know that's not the explanation, say because you get the intermittent clicks while staying within some band and don't tune outside that band, you could try a diagnostic, by running the following macro in the "Elecraft KX3 Utility" app on your computer:

BN;FA;AK;

Run the macro once and note the output in the "Command Tester/KX3 Macros" output pane. Here's some example output:

BN;FA;AK;BN01;FA00003581500;AK002601;

This example output reports the VFO A freq (~3.58 MHz) and KXAT3 L, C, & config settings. I.e., "AK002601" says there are currently no L's in the L-net ("00"); C13, C9, & C8 are in-circuit for a total of approx. 454 pF ("26"); and some standard L-net configuration ("01") that I don't know because the KX3 schematics aren't yet published.

OK, now use your KX3 until you hear the next intermittent click. Then run the above macro again, and compare the new macro output with the old. If the "AK" command output doesn't change (and you stayed in the same band), then I don't know what is causing your clicking, but I'm thinking it's not a problem with the KXAT3. If the macro output does change, I would contact Elecraft Support for help. There are other diagnostics that can be run.

Bob NZ9E

Re: KX3 ATU goes off/on during send?

Gernot,

I take some of that back. If the macro output does not change, there still might be a problem with your KXAT3. I think my test is still worth doing, because if the output does change, then there would seem to be a documented problem to go to Elecraft Support with.

Feel free to ask me for clarification, if I've confused more than helped.

73,

Re: KX3 ATU goes off/on during send?

Bob,
thanks for pointing out to the diagnostic commands. Played a bit and I
get the impression there is nothing wrong, basically.
My ATU does this click whenever SWR becomes bad and switches between
"AK105001" and "AK145801". Not a bug, but a feature as it seems, to keep
SWR low.
The K2 ATU does not behave like that, hence my irritation.
The guilty one is my narrow antenna, 40kHz on 40m. During the ARRL DX
contest I worked stations all the way up to 7070, which explains the
need to adjust SWR. Pressing "ATU Tune" after the click of course yields
SWR 1:1.

Can somebody from Elecraft confirm that automatic retune during send is
a feature, and the relays ara capable of handling the power without
damage? And, while I am thinking about it, why not retune during receive
if the setting is already memorized? That would be really cool!

Bob, thanks again for taking me into the right direction.
