Since the K3/K3S has the ability to indicate voltage on the display, from
actual experience, between RX and TX there should be less than 0.5 volts
difference in CW mode, key closed at 100 watts output. Anything greater
indicates poor power supply regulation, or more likely, excessive
Good Evening,
The Elecraft CW Net is a directed net. There is no need to call CQ
to get my attention; my location allows me to hear very well. Just wait
for me to call for check-ins then send your call or a part of it as a
hail sign. This allows me to gather two to three stations and
Here are the last two logs from the last two weeks nets. Again thanks to all
who signed in to the net and to the relay stations. We meet on 14.303.5 at 18Z.

Can you fill us in on exactly what versions of macOS and WSJT-X youare trying
to use?
Also, did you pay attention to the release notes for WSJT-X and use the correct
values in /etc/sysctl.conf?(I was bitten - badly - by that myself!). I'm still

With KX3 I'm getting "Hamlib error: IO error while opening connection to

I saw this problem with my K3 #4xxx and discovered a large voltage drop between
the PS and K3 using the provided power cable. Cured the problem by: 1) shorter
& fatter power cable, 2) increased the PS (Astron 30A linear) to 14.5v, and 3)
running the K3 utility power calibration _twice_
I've grown attached to using a wireless
mouse and wonder if that is also an option
with the K4 & the monitor?
Thanks & HNY,

Hi Dave:
I am having the same problem, get an error message failed to load amp
driver or something close to that. See mu post earlier this month. The
KAT500 and the KPA1500 remote programs work perfectly.

Yep, the power control circuit does have a bit of initial character
overshoot. This is noticed when changing power levels or when
changing bands and a few other instances which I don't recall. Since
it occurs on the first CW element only, and doesn't fault the amp, I
don't consider it of
Ok, thanks.

Sorry, but that setting is not saved over a power cycle.
It is good to hear the Fixed Audio Output is serving you well.

There are two things at play here. First, the KPA500 has an unregulated power
supply. On first key down, the power will spike, then quickly lower as the big
filter capacitors decay from their peak voltage to the rms voltage. This is
normal and we all see it. While I am sure you are seeing this,
I also just caused this anomaly by first slightly adjusting the K3 power
output. First character again sent the KPA 500 to 700 watts. I'm going to see
if I can find an accurate watt meter and see if I can see something on the K3
output.

Recently I added to my K 2 the Fixed Audio board now available from Dave

perfectly. I have noticed that when I have set up the Bar display to show
ALC so I can monitor ALC (I monitor RF with an outboard meter) that when I

I’ve never seen this on my K3/PKA500/KAT500 setup.
Just went back into the check, and all is normal!

1) I can never GET to transmit on 2 meters. It goes into "HI CUR"
within seconds after switching to the 2 meter band.
2) The receive voltage is 14.3 VDC, and about 1.49-1.51 Amps.

Just started noticing that occasionally the first character sent on CW will peg
the watt meter on the KPA500. It does not fault. Sometimes a QSY to a
different band or even a different band segment will trigger it again,
sometimes not. Both of my antennas require my KAT500 which seems to have
Well it turned out that I had the audio codec set to mono in the PC, so it was
simple. It seems to work now. MR in a few minutes so we will see.

I have a question as to the video output connector.
The K4 appears to have an HDMI connector for the monitor output.
I have been told by other manufacturers that using an HDMI connector
involves royalty fees or some other licensing.
Is this true? If so, how has Elecraft navigated this
After a failed windows update, I had to reload some of my software. Among that
was the KPA500 remote utility. I did what I did before, went to the elecraft
support page, found the KPA500 download, did the download, it said to also
download the dot net framework. I did that and then I downloaded
Clay,
Have you measured the voltage displayed by the K3S during transmit? A
low voltage is a common cause for Hi Curr.
Reduce the voltage drop in the power cord by running directly from the
power supply (no DC distribution boxes) and make certain all connections
are tight.

Unfortunately, illness forces me to sell my KPA1500 s/n 373.
It has Temperature Sensor and Minimum Load mods installed.
Works perfectly. There are so few of these for sale I don't
know what a fair asking price would be. I'm thinking $5000.
I'll probably also sell my K3. perhaps someone would
