The external ALC test procedure P.4 rev B of the K3 external ALC Modification
instructions calls for a 1K to 10K series resistor between the negative and
the K3 ALC pin. Is this resistor also needed when using the ALC with an
amplifier, in my case an Icom PW-1?

Happy New Year!
I am looking for a sub receiver for my K3. Of course, I can order it from
Elecraft. However, if any of you would like to part with your surplus sub
receiver KRX3 or you have an unbuilt KRX3 kit, please let me have your price
off-the-list. A second hand KRX3

On the K2, the SSB module is the toughest to build, since the board is more
cram-packed than any other. I'd suggest the ATU first, unless you feel up to
tackling the SSB module first.

All the right angle BNCs I've seen are M-F type. But you could use a
M-F right angle and a M-M connector to make what you need.
If a M-M right angle exists, it's probably carried by The RF Connection.

I would call and inquire.

Hi Jamie,
Why not just make a couple of short (6) BNC to BNC cables using some RG58?
Thats what I did here with no detectable signal degredation and a whole lot
less room taken up behind the rig.

I went through the dial calibration process with my K2 as outlined on Don's
(W3FPR) web page. After adjusting C22 as called for, I ran CAL PLL. When it
finished, the radio was in a frozen state from which I can't recover it. The
only band that works is 30M, which seems normal. All the others can't
Hello Jeff,
I would wonder whether the PR6 can be installed inside the K3 main body similar
to the K144XV. This will possibly tidy up the cabling.
In fact, in the thread of KPA500, I did ask the possibily of having a 6 m
preamp
built inside the KPA500. Without the PR6, K3 is relatively deaf
I was asked by John, K0VET, to verify a behavior he observed last night
on his K3. He was playing with HRD and found that by changing the IF
Shift while transmitting that it took him off frequency. He
demonstrated it for me and sure enough, his radio went off frequency
(1.947 LSB).

Hi Johnny,
I have no doubt that it would physically fit in the K3 but I'd have to defer to
the guy's at Elecraft on how to cable it.
I guess that if you have the KXV3A installed but not the 2M module I dare say
that you may be able to do it with TMP cables as is done with the 2M
transverter.
I am trying to make the KRC2 work with my Kenwood TS-590 radio.
So far I have followed all instruction manual and tried all the various
settings without success.
Anyone here has experience with making the KRC2 work with Kenwood.
Thanks N1DZ Maarten

HNY 2011. Just built an XV432 transverter and am a bit stumped -
Alignment was tricky as the output power keeps dropping as it heats

6W in 5mins. Using signal generator. If
Hi Bill,
It's your choice, either will do the job with the P3.
But, If you want at some later stage to go with the internal K144XV transverter
then you will need the KXV3A, the only difference is that the KXV3A has the
connectors for the internal transverter that the KXV3 misses ou on.
Jeff
One or the other is required. See the red text on
http://www.elecraft.com/P3/p3.htm
Note: Either the KXV3 or the KXV3a K3 option is required to feed the K3's
IF output to the P3.

Hi all,
My K3 has developed a problem...
Power output is down to 70W and the LCD back-light flickers on tx. The Low

up briefly once.
I suspect a DC power problem but so saying, the voltage at the rig is 13.9V on
transmit at 70W and
the rig is drawing 13A. The problem
Hi all,
More info...
Was unaware of the power recommendations on 50MHz...
I was running 100W calling CQ on 50MHz when the problem suddenly arose.
Maybe running 100W on 6M has been the cause?
If I dial up 100W on any band, RF power as indicated on the K3 display is
70W.
I am unable to get more
Paul,
It sounds to me like you have a voltage drop issue on transmit.
Have you checked your power supplies voltage under load and the supply leads to
the radio?
That's where I'd be starting to look first.
