[Elecraft] Tuning Random-Length Wire Antenna with K3 Internal Tuner??

[Mike K8CN]

Mr. Mike,

Be sure you have the KAT3 internal ATU "enabled" and not bypassed, be sure
the proper antenna is selected (ANT 1 or ANT 2) for your random wire, and
press (momentary) the ATU TUNE button.  The relays will clatter a bit, and
you'll see the displayed SWR ratcheting down, maybe up for short time, as a
tuning solution is searched.  If the SWR isn't low enough for your tastes,
press the ATU TUNE button again within 5 seconds of the conclusion of the
previous attempt's end, and the ATU will try again, often with slightly
improved result.

Don't be surprised if you experience RF gremlins in your shack with a random
length wire without a counterpoise.

Mike, K8CN
(hoping to be back at NEAR-Fest next year!)
