Thanks to all for the great suggestions (the SNR of the responses was
appropriately high!).
I did some experiments with the RSP2 and HDSDR. It was very close to what I
was looking for and I will revisit it in the future when I am looking for
specific interferers, but I set it aside when I saw a v
In looking back at my original post..I omitted the word NOT.
Thus "all PL-259 connectors are not all created equal".
Sorry folks, and thanks Jim for catching the over site.

Situation: Tuner inline between K3s and known good dummy load.
1) Tuner off - K3s tunes 1:1 instantly
2) Tuner on in bypass - K3s tunes 1:1 instantly
3) Tuner on, and in Manual OR Auto Mode, tuner clicks and then Mode

All components in signal path obviously AND tested know
The ATU blinks the MODE LED when a tune has been started, but not enough RF
is arriving from the exciter to proceed. It's waiting for about 20 watts
from your exciter. If you want to cancel the tune, tap TUNE again.
Don't use both the K3 internal ATU and the KAT500 ATU together. One or the

Hi Clay,
I could easily reproduce your problem. Note: I do not have the AUX cable
connected. Apparently you just pressed TUNE on the tuner. That will not
start the K3 sending a tuning tone. Thus the blinking LED (MAN led if in
manual mode, AUTO LED if in in AUTO mode). You must press and hold the

With tuner in bypass, and "TUNE" held down, SWR on K3s is 3.6.
Repeat with KAT500 in Manual mode, the SWR reading on K3s is 12.6:1 or
higher.
Repeat in AUTO Mode, and SWR goes to 99.9:1 because the KAT500 breaks

Did not include that in original post, but I AM holding the XMIT/TUNE

Put a dummy load on output of KAT500 and if that doesn't give 1:1 then you have

We did that, and it was an instant 1:1
Finally figured it out... this particular KAT500 spent its life hooked
to a basic K3... It was behind on firmware updates by ELEVEN versions...
Updated to current and it immediately started working... The version it
had was PRE-K3s by several years.
