You would be better off not touching the power knob once it is set for
your desired power.
Unlike most other transceivers, the K2 and K3 control power output using
a closed control loop.
The setting on the power knob is compared to the power output (as
measured by the wattmeter) and
My problem has not been with the firmware, but rather with the

Tom,
Make sure you check the pin-outs and make sure they are the same on both
cables. Elecraft does some different things with their cables than you
might find if you bought the same cable from other sources.
Hope this helps.

Ian,
Just make sure the cable conforms to the Elecraft manual pin outs. Some
(many) VGA cables will connect the coax shields together at one end or even
both ends and some tie those to the ground pin and/or shell.
I made my first cable since I had 15 conductor ribbon cable the connectors
The power lead/barrel connector on the second #2334 KX3 is starting to
intermittently drop out. Most notable if you remove the internal
batteries and try and operate from a supply only. It seems it is the
socket itself that is duff. Yes using the Elecraft power leads not
something homebrewed.
Do you need the RIT mode when the other station is zero beat with your signal?

The P3 should work fine with 11V. When I tested mine it worked down to
about 6V or so, although that is not guaranteed.
It is normal for the K3 power connector to show a voltage drop compared
to the 12V input connector, although 1.5V drop seems kind of high.
Could some of that drop be in the
He's got the SVGA board in the P3. If he hasn't done the higher current mod to
the K3 to get enough current out of that jack to run the P3 and SVGA, chances
are it will trip the auto resetting fuse in the K3. I didn't do the mod to

But if you have several hams in the round-table, you sure do need RIT because
you know all hams are not going to be zero beat. Besides that, yes, ever if
your one QSO partner is zero beat, you need the ability to slightly change the

Turned it on, but it didn't help. I've since turned it off, as I understand
that it causes slightly higher battery drain.
Tnx for giving it a shot though!

OK, Jim. RX ISO *should not* have helped, but what the heck. In the

When a station is zero beat with me, I hear him at my sidetone frequency. I

Not positive with no schematic, but I think that's a VGA cable and does
not have all 15 pins wired straight through from one connector to the
other. If true, no, it won't work.

Sounds like something may be hosed in your Win/XP SP3 or the old desktop

If I had to guess, I would say that you have a KX3 from before they
began gluing the power jack to the board. The solder pads just were not
enough to stand the lateral forces of plugging and unplugging over time,
so Elecraft began to glue the power jack - I don't recall what serial
K2 6299 had the aux power out mod installed on the factory supplied card.

I've never connected a serial cable to the KPA500, I built it and used

Jeremy,
A power reading of 0.1, 0.2 or 0.3 is only residual noise on the power
detection circuits. Since you do not have Q7 and Q8 installed, your
real power output is zero.
Yes, go ahead and change Q11 and Q13. That is not certain to change
anything, but it will do no harm.

Fred,
You do not need a separate serial cable, but you must plug the serial
adapter into the KPA500 instead of the K3/P3 combination to download
firmware to the KPA500.
Connect your serial cable directly to the KPA500 and then do the update,
then connect the cable back on the P3 and do the

Yes, If you have a VGA Y cable in that cable mix, it would be pulling

If you are updating to the latest beta (perhaps soon to be production),
you will want to load the K3,

I don't know that a mixture of levels will cause a problem, but I do
know that the latest features are designed to work together.
