Any more specific info?

Hi All,
I seem to be having a problem with my RemoteRig operation. Everything worked

OK Don,
I thought that the KX3 would display the SWR reads on the KXPA100 when this

So why display an almost 1:1 between the rig and the amp on the KX3 display

I have not confirmed your observations (I have all resonant antennas, so
it makes that check difficult).
However, I would think that the SWR reported by the KX3 would be the SWR
between the KX3 and the KXPA3 (which should be low) and the SWR reported
by the KXPA100 would be the SWR presen

Hi,

When having the KXPA100 ATU enable, by pressing the TUNE button, I can read

It seems to me that using the two smaller packs would have some advantages for
your application. They would each be able to power both the KX-3 and the
amplifier, just for about half the time of the single larger battery. So you
would have to switch over to the other battery at some point. B

Batteries are probably the #1 topics on the Summits on the Air (SOTA) mailing

Good recommendation. I have two 4S1P LiFePo packs (purchased from Buddipole)

The base K3 is protected from reverse polarity by a series diode as well
as a diode to ground and a resettable fuse.
So it will not power up if the power leads are reversed - and normally
will recover with no damage when that condition is corrected.
The KPA3 is not similarly protected - the diode

LiFePO4 will have a total cycle life that is 5 to 10 times longer. In
round numbers 2000 charge/discharge cycles vs. 200. The total life cycle
cost is lower too. 5x 40 AH SLA will set you back about $300.

Hi George,
A working K3 didn't power up at field day. That probably means that the
power leads were reversed and embarrassment causes that information to be
withheld. People here on the reflector probably know what gets damaged when
power is reversed. Chances are that is very easy to check if you

I wouldn't mess with Li-Ion. The voltage from the pack is either too low
(3-cell) or too high (4-cell), and they are quite dangerous if physically
abused.
Instead I would go with 4-cell LiFePO4, another form of Lithium battery.
The iron stabilizes the lithium, and at no part of the discharge or
