Does anyone "juice" their K3 bu turning up the PS voltage to 15 volts or so. I
do that with my K2/10 to get some more power out. I was wondering if that is a
practice with the K3 which I am not doing.

Lee, forgive me if I'm being dumb, but with voltage regulation etc.
that shouldn't make any difference, should it?
I no I wouldn't do it.

Why? I think it is an interesting question. I suspect that increasing

I have a small mountain of data with efficiency and transmitted
intermodulation versus supply voltage for my K3, but have yet to finish
analyzing it.
For the most part, higher voltage = better transmitted IMD, but the
lower the overall DC efficiency (RF watts out / DC watts in).

I run my K3 at 80 Watts, unless I run less.
At 80 Watts vrs 100 Watts I am down 0.97 dB, That loss will not be noticed on
an S meter, or by the ear of the op on the other end.

I am very interested in this topic!!!
I DO juice my KX1. I run it at 14.2 VDC when at home and it makes quite big
difference in the output power! Of course, in the field I use a 12 VDC
battery. I have almost never used the internal battery setup with a nominal
9 VDC.
I am a big fan of more power
No.
I've never found any value in increasing power unless I can go up at least 6
dB - multiply my output power by at least 4 times.
To most ears (and many meters), that's about 1 "S" unit.

I believe the way ALC works in the rig, unless you tell it you want more, it
wouldn't do it even if you increased the capability. And it is the software
that tells it how much to put out, so unless you change the software so it will

It all depends upon the circumstances.
When I was trying to decide whether the additional 2 db gain from a
larger yagi was worth the additional cost (yes, I know about the
additional benefits of a tighter pattern), I generated some audio
recordings comprised of CW sent from CW Player (freewar
If you look at the DC current, you'll find that lower supply voltage
for modes such as RTTY and CW are considerably more efficient for the K3.
My measurements suggest that for a given output power, the K3 is more or
less a constant current load. At 100 watts, the current is around 18A,
so the

This is interesting. I run 100 watts output on RTTY, CQing and working
stations at a continual flow, and the fans hardly run at all. The PA
temperature stays down. I wonder if there is something unique going on with
your K3(s)? One user found a fan wire impeding the b

Earlier today, I remarked that one of my K3's was running
warm in the NAQP RTTY after an extended number of RTTY CQ's.
Tonight I did a little experiment - key down at 100 watts
for four minutes while noting PA Temp and fan speed. It
turns out that there really is no problem. Both K3's behaved
Jack,
I am glad to hear that you have found success with that, BUT ---
Be careful with "juicing" the KX1. Yes, the power output will increase
with DC voltage, but running the KX1 at greater than 4 watts can cause
problems. The peak RF voltage must be less than the breakover voltage
