[Elecraft] K3 Internal Tuner Question

[John Lemay]

John

I would struggle to explain this, but I'm quite certain that what you are
seeing is quite correct and nothing to worry about. The Palstar is showing
you the swr of the antenna and feedline. The K3 ATU is matching the
transmitter to this impedance. The ATU does not change the antenna
impedance.

Subject: [Elecraft] K3 Internal Tuner Question

I installed the KAT3 over the weekend and the construction and calibration
was successful. This evening I hooked everything back up to check reception,
tuning and swr. I have it set to AUTO, when I tap the ATU TUNE switch the
tuner does its thing and I read a 1.0:1 swr on the K3 meter. I have a
Palstar Wattmeter installed between the K3 and the antenna and for some
reason I am getting a high swr on the Palstar meter of 5:1 and don't
understand why. I have a multiband vertical antenna with a 4:1 Unun at the
base of the antenna. Am I missing something here?

A little hand holding would be appreciated.

Regards,

John W9QP
