I was seeing high SWR using my K3 to drive my new 300w HF amplifier,
with amp bypassed and QRO tuner (that follows the amp) switched
directly to dummy load. This was on 20m. I have the K3 ANT1 (no
internal tuner) connected to a MFJ tuner and

Asunto: Re: [Elecraft] How accurate is the K3 SWR
I am pretty new to the K3 world and just getting acquainted with the
radio. I have a Vectronics Vector 500 antenna tuner with a cross needle
swr meter. I notice a disparity between the swr readings on the K3 and
on the antenna tuner. So, how accurate is the K3 swr reading? I can
imagine that
If the K3's antenna tuner is not set to 'Bypass' then there will almost
certainly be a
difference, since the external tuner is reading the SWR between the output of
the internal
tuner and the antenna, while the K3's reading is between the K3's final
amplifier and its
tuner. This difference
Robert,
I will not answer your question, but may offer some things to
contemplate. If I had to make a guess, I would say that the K3 SWR
readings should be accurate.
Now, while saying that, if you are adjusting for a 1:1 SWR, the exact
calibration of the wattmeter will not be any issue, just
