One really cool optional setting would be a double-frequency output on LF/MF at
~ 0 dBm level. That would allow the K4 to drive directly some of the common
push-pull class D power amp designs which require, for example, 950 kHz drive
for a 475 kHz output.

I am testing my KAT100, which had been sitting idle for a number of
years. It is connected to the K2/100 via the DB9 cable as described
in the KAT100 manual. The two are interconnected with a coax cable
and Ant1 is connected to a dummy load.
1. Apply power to KAT100.
2. Turn on K2/100.

Don,
Thanks for the tip -- that was exactly it. I checked and replaced D16
and D17 and all is well now. (Both were showing the same voltage drop
in both directions.) I gather from your description that the built-in
wattmeter forms a negative feedback loop with the power adjustment.
My diodes an
That makes me happy!
I'll just quietly sit back and continue to use my KX3 until the K4 arrives.

Just dropped better than $2k finishing up outfitting my K3s and P3, but
if you and the rest of the Elecraft crew keep this up, I am going to
have to get in line for a K4HD!!!
Not sure if my (very HAM supportive) XYL will sit still for that. ;-)8-):-D

Fred says "Optionally, you can use the KX3 Utility to monitor an
extended display of characters sent from the KX3's keyer." I assume
"keyer" could refer to the paddle connected to the KX3.
I can type characters into the Utility Terminal lower window and
Transmit the CW. The characters sent a

As of now the LCD still shows panadapter(s) if an external monitor is attached.
It would be possible to use more of the LCD for TX monitoring, text decode,
etc., in this situation, but I can't give you any specifics at this time.

You can turn the brightness down to something quite low. I wouldn't suggest
turning it all the way off, as the display shows critical operating status.

Tentatively, up to ~5 dBm, using XVTR OUT only.

Probably first ship.
Yes, I think all of these have been asked and answered … of course :-)
I don’t recall the specific answers to the LF transmit question. I asked about
the XREF some time ago and the answer was that it would be standard on the K4
and not an option as it was on the K3.

Jonathan,
The normal cause of that HiCur message is a failure in the wattmeter of
the KPA100. Re-alignment will not help.
To test for that possibility set the power knob for about 50 watts,
connect an external wattmeter and a dummy load. Then go Keydown and see
what the actual power output
Will the K4 transmit at 136 or 472 kHz, and if so at what power level and
through which antenna port? If so, at first ship or in the future?
The K4 brochure shows an empty hole for XREF, will this be available at first
ship or in the future, and will it require an option board?
My apologies if
K2 #2462
I just upgraded the KPA100 from Rev A to Rev D, and installed the
upgraded shield, under the philosophy of "better late than never" :)
I am noticing two problems, when connected to a 50-ohm dummy load:
1) In TUNE, the display briefly shows "Hi Cur", followed by a strange
power/SWR indic
Yes, in addition to using the VFO knob to change frequency, you can change the
K4's frequency by clicking on the desired signal with a mouse or by tapping on
it with your finger.

Hi all,
Can the K4 display be turned off if one does not want it "on" ? No flamers,
please ! ! ! !
