Hi Guys,
I made a video and posted it on youtube to better explain the issue I'm having.
Please watch and then reply to it here if you would.
Much appreciated

I think what happens is KAT500 needs few msec to determine the operating
frequency and measure SWR. There is currently no delay between PTT going
into KAT500 from the radio and PTT going out into the KPA500. These few msec
is enough for KPA500 to switch itself to fault condition.

Why are you using the figure on page 6? That is only needed if you have
an external device that controls the key line (the box at the top right
corner in the figure on p.6). If you don't have such a device, the
applicable configuration is the figure on p. 4. With only the K3, KPA500

Sherrill,
I believe you are asking about the AGC settings. If so, know that the
settings are dependent on your local noise levels. I suggest you create
your own.
Use the information in the Noisy K3 article on my website
(www.w3fpr.com) as a guideline.

If you're seeing E's and T's, try using a much narrower bandwidth,

Make sure you are only routing the AMP keying line from the rig through
the KAT 500 to the amp. The tuner always interrupts this line when it is
tuning. This can be done either via the the AMP keying line RCA
connectors on the Rig, KAT500 and the AMP, or via the KPAK3AUX cable
connections
It should be noted that the KAT500 does not regenerate the PTT
signal, rather it (only) interrupts it (by opening relay contacts).
Therefore it can't really delay the initial PTT signal going to the
amp... it can only interrupt it as fast as it can, when it detects
high VSWR.
As Gary mentioned,
So with the new firmware the KPA500 would tolerate a high VSWR for a few more
milliseconds to give the tuner time to interrupt keying?
I was thinking of ways to not send a keying line with the K3 when using tune.
But this doesn't seem possible with the K3...I take it the PTT is used
internally
IMHO there is a big need for a command that can be use to define things
back to the same state. One big rule in programming is you always set
the state of things so you are always dealing with a known starting
point. The command structure in the K3 does not permit this.
A number of things in
Thanks to all who responded to my questions regarding tuning the KAT500 when
the KPA500 is in OPERATE mode. Changing CONFIG: TUN PWR back to NOR and
reducing K3 PWR has helped to keep the amp from tripping to STANDBY from

Hi Eric,
I do not have the AUX cable. As described in the video, I am only using the
RCA cable from the Flex 3000 into the KAT500 and then another cable from the
KAT500 down to the KPA500.
I am not using this with a K3 radio, which in that case, would only use the
AUX cable and no RCA Key

Stop tx after the first tune. Then quickly press the tune button on the KAT500
and the immediately go back into TX. That will enter the fine tune mode.

That may be cure for KPA500 + KAT500 combo but KAT500 supposed to work with
amps of other manufacturers. My conversation with Elecraft tech support led
me to believe that some sort of TX delay can be implemented in future
firmware release.

A while back, I wrote a CW functional test for the K3. In doing this, I ran
straight into the programming problems cited earlier by Ed. My solution wasn't
very innovative or elegant (not being involved in the firmware development at
all), but it was adequate and met the requirements.

Hi,
Still can't manage to get any improvement doing this. Anyway, right now the
tuner is doing a great job to my G5RV on all bands except 15m and 80m. For
those bands the raw SWR is above 12:1 so is outside the design parameters
for the tuner. These are screen shots for the bands where the tuner

before. 15KHz is suspicious, I don't see it on other bands. Hope all

Knut,
You might try adding or subtracting feedline at the shack end of the
feedline to bring the SWR down on those bands. I would suggest
experimenting with an antenna analyzer rather than the tuner - you will
be able to see which way to go for making improvement.
