Good Evening,
The time change is next week, November 3rd. I'd just as soon they left
it in either one place or the other and never changed it again. This
time of year it's difficult to tell if it's day or night anyway :)

I think pretty much all Li-ion chemistries can be charged at constant
current to 80 percent, then at constant voltage. The last 20 percent
takes a long time. The charging is terminated when the current drops
below a certain limit in the constant voltage mode. This is mandatory:

Universal recommendation for long term storage is 80%. Otherwise, charge &

Tom,
That sounds strange. I would first suggest checking all the Power
Supply to K3, and either K3 AUX DC to P3 or the Power Supply to P3 power
cables for loose connections.
A drop from 14.5 to 14.7 volts down to 12.8 volts indicates a high
resistance power cable or a bad power supply.

I have Lithium batteries in my laptop, my KX2, my electric razor, a
tactical flashlight, and maybe some other things. I use the dedicated
chargers for each of them.
I think the dedicated, automatic chargers fill the batteries to 100%, so
there must not be a lot of caution to only charge them to
My LiFePO4 charger has a charging program to stop at about 80% and I've
been told that they like that if you're going to store them for awhile.
Don't know if that applies to Li Ion, there are a lot of lithium
chemistries these days.

It seems the K1 and KX1 hold a fairly high value on the used market after
their demise. I'm hoping the K3 follows suit, so I can upgrade to the K4
later :)

I recently read that Lithium Ion batteries should be charged only to 80% unless
you are going to need full capacity. Supposedly makes them last longer.
Anyone ever heard of this?
If true does this also apply to LiPO4 batteries?

I would like to control the Bset AUX with a macro.An SWT command works, but
does not give a defined state. It just switches between main and aux.Is there a
command which forces AUX in a defined state, no matter its current setting.73

Vic,
What you're missing is that an antenna and its feedline are a SYSTEM,
and antennas can be unbalanced by their surroundings -- ground slope,
un-equal mounting heights, conductors in nearby buildings or structure,
trees, towers, etc. Any unbalance in the SYSTEM results in common mode

This is not unusual when the loads presented by the antennas (or tuner) to the
amp are different. This can even be true when the SWRs are identical if the
actual +/- reactance of one is different than the other.
This is most noticeable on lower freq bands where the amps gain is typically

And if you don’t have a good condition original shipping container for the K3/S
(or P3), it’s worth the small cost and wait to order a new one with the
internal foam supports from Elecraft. The shipping containers are available on
the spare parts menu.

I want to echo my appreciation of Elecraft repair service.
I had my K3 in a few years ago after it malfunctioned during field use.
They also went through it and made all sorts of additions and calibrations.
Really well worth the moderate cost and inconvenience.

In my view, that is a very wise decision. I'm 77 yrs of age ("seasoned

Jim,
I have to disagree about balanced line. Unlike coax, both conductors are
exposed to external RF fields, so common mode noise will be rejected. If
the antenna and line are properly balanced (not always easy to do, I
admit) and if it is fed through a balanced antenna tuner, there is no

This is a follow up on the VFO B control problem with a friend’s older K3.
Thanks to all the ideas and suggestions! I do agree that it is likely the
infamous K3 connector problem. As I mentioned, the K3 is an older unit. The ham

Or did I read the newsletter wrong, my brain being soaked with RF in the shack,

Yes, that is the solution. But it shouldn't have to be for an amplifier of
the KPA1500's price and class. Further testing shows that on other bands,
with an SWR of 1.5 to 2.0, if the tuner is IN, it also goes into random
retunes. When the tuner is in BYPASS, the KPA1500 is happy. Also very
