Good Evening,
As I had suspected twenty meters was filled with contesters. Signals
receded into the distance like grain elevators on the plains of Kansas.
I scanned from 14003 to 14110 kHz without finding a gap. So I went back
to writing code.
Forty meters was open after the contest
Memorial Day Weekend edition the Elecraft SSB Net had 19 checkins. T-storm
static here in Colorado Springs made things a bit difficult. Relay stations
were once again a tremendous help. Thanks to Brian K1NW, Steve WM6P, and Phil
NS7P for your assistance. Good to hear John N6JW joining us
I understand the K4 can be remotely controlled by another K4 via a direct
ethernet connection. How easy is this accomplished with the K4? Is the
operation on CW and SSB seamless provided a decent connection is available?
I may wish to remote between two homes at some point and having the

I think you missed Dick's point. The ATU should have a signal that indicates
when it needs to do a tune (or is doing one). Simply use that signal to operate
a relay. That relay either passes the Keyout signal to the PA (normal), or
opens the relay to unkey the PA (tuning). That is

Hi Buzz,
So the issue is how to prevent PA PTT while in low power mode.
In case you could just switch a remote relay which yes/no passes the PA PTT
signal you are all set.
You could use the switch capacity of the Remoterig boxes and activate a relay
remotely.
Remoterig provides a web-based
I didn't say " a hair's width," I said "a hair," a technical term
understood by OFs as an approximation. I also didn't say "pinch the ribbon
cable," because that is not the side of the cabinet where the problem lies
in my experience.
Now, are you guys telling me there is an actual wing-nut on
Thanks, Dick,
But here is the real issue, not reported in my post.
My antenna - my only antenna - is a non-resonant 600 foot square loop which
provides amazing performance especially on high bands. It presents SWRs that
are higher than the no-foldback limits of the KPA1500. I believe that
"The KPA-500 transformer should be more than just a "hair" away from sides
(step 6 above) as there are rubber bumpers and a ribbon cable between that
should NOT be pinched. "
Over the production life of the KPA500 the transformer design, and perhaps the
supplier, have changed several times.
This is the first in an occasional series that will highlight one K4 operating
control or other feature. K4 owners are encouraged to give the examples a try,
allowing them to gradually become more familiar with the transceiver's
capabilities -- including some they may have missed.

Buzz: Our KAT500 and KPA1500 antenna tuners interrupt the key line with a relay
for ATU tuning (which is done at exciter power, as we can’t hot switch ATU
relays at QRO and amps don’t deal well with the SWR swings encountered during
ATU tune). The K3, like most exciters, does pull down the KEY

Hi Mark,
I’d verify this with Elecraft Support.
When I got my KPA500 it was used and shipped with the transformer in a
separate box.
The assembly manual
The KPA-500 transformer should be more than just a "hair" away from sides
(step 6 above) as there are rubber bumpers and a ribbon cable between that
should NOT be pinched. Refer to Kit Assembly Instructions page 35 and figure
52.

Just saw your QRZ page. It appears that you are operating your
station remotely, so my simple suggestion obviously won't work. Hope
someone else may have the right suggestion for you!

If I am understanding correctly, you want to bypass the amp and use
low power from the K3 into the tuner in order to tune the antenna.
Does the amp have a 'bypass' switch on it? If not, then you can put a
switch in the keying line to open it when you want to bypass the amp.
If you are
I think the answer is no, but I'll ask this question anyway.
The station configuration is K3 followed by amp followed by automatic
antenna coupler, where the Key Out line of the K3 is used to switch the amp
inline.
I would like to generate RF from the K3 without switching the amp inline
Hi,
A report on recent events with my KX3:
When I tried to use it yesterday, I found that several buttons
were no longer responding: PRE, ATT, MSG and CLR.
Tried power-off/on, no change. Removed the battaries for 5 minutes,
no change.
I was able to go to setup and started SW TEST so I could
There is KPA500 buzz (normal), and KPA500 BUZZ (abnormal). I own two.
KPA Numero Uno was bought way back when, when the kits were first
available. When I first built it, it buzzed something akin to to your
teeth clacking when you notice a full-grown T. Rex is standing next to
you. At that
