There are excellent reasons for QRP.

Two answers below.

1) Can the KXPA100 and KX3 tolerate the higher voltages of a fully
charged 14.8V battery pack? (In the range of 16V).
No. The products are not guaranteed to FAIL if you apply 16 V, but they
are not designed to operate from 16 V, either.
2) Do the KX3 or
Very FB, Wes, and it has the requisite two meters: plate current and
grid current.

The PA (KX3 or KXPA100) operates directly off the supply power and

Thanks, Lyle. The additional question I was asking here is if the
KXPA100 pull proportionally less current
I think some where my original question go lost. Can the K3 operate key
down at 100W's.
I did get an answer, yes - 120w for 24hr's... So the answer is yes.
I complicated things by adding JT65 and that I operate at 0.5 to 2 watts
with my KX3, but up to 20w with an IC-706. Yes, if I am -25db
Well, yes... {less powerful engine} After the late 60's the rules were
changed to require all cars to operate under the same limits. NO more
turbine cars... (for a $6 ball bearing...)

I'm not a QRP fan for DX. However, one can definitely copy a weaker
signal with JT65. No matter how much power you have, you can't work
them if you can't copy them. It seems like the magic combo is 1500 W
and JT65 on both ends. I think guys are resorting to this on 160M to
try and squeeze

You are misinformed. JT65 is NOT a LOW POWER mode, it is a WEAK SIGNAL
mode. BIG difference. Caps added for emphasis. On VHF/UHF, it is quite

I am thinking about replacing my ORION II with a K3 as it is smaller
(much smaller).
My OII will do RTTY (or JT65) at 100 Watts (with the fan option).
What will the K3 do? (I know it has fans, too)
I hear lots of comments about digital power out for the KX3 and heatsinks...
I guess the question
Thanks, You didn't use a brick?
I expected the K3 to handle 100W as there were no comments that I remember.
With your comments it doesn't matter how the 500W amp would work as I
doubt if I would want to run more than 100W, either.
I also have a IC-706 100W rig but it will only handle ~40W
It takes 80W drive to get my amp to full output. I've run my K3
continuously for hours at a time at that level on JT65. No issues at all
and never even noticed it getting hot.
