If they are NiMH cells, did you set the minimum voltage in the menu to
8.5v? That might be what's shutting it off.
Still might be a good idea to buy new cells.

It is often that the no-load voltage of a battery is OK, but as soon as
you draw any current, it goes "belly up". You can monitor the voltage
of the pack with the KX3 alternate VFO B display. Try to see the

I am finding the same with my Eneloop NiMH batteries. It seems they are
showing diminished performance after three years in my KX3. This could be a
good thing as I can replace them with a higher A/hr set of batteries. Until
then I will run them into the ground.

Good to know about Eneloops -- they're what I've got in my own KX3. I'll
keep track of how long I have 'em in the radio and replace 'em around 3
years.
But I use a Talentcell LiPo pack that gives 5, 9, and 12v. It's
lightweight, comes with a charger, and was intended to charge items that
take more power than a phone. It gives 6A at 12v with 8300 mAh. I keep it
external to the radio of course. I use a smaller one (12v at 3A)for my old
K2 since the old SLA battery died. I'm tempted to get their top-level
12v/11000mAh/6A pack for some longer endurance. The 8300mAh and 11000mAh
packs also have 5v USB and 9v coaxial plugs, while the 6000mAh is only
12v/3A coaxial. The prices are all very reasonable, and the packs are
compact and have tough plastic cases with power switches and LED
indicators. With a Y-cable, I can plug in both the KX3 and the PX3, AND
have the charger plugged in to keep the battery topped off if the drain
isn't too severe. The switching wall wart chargers are even fairly quiet RF
wise, as far as I've been able to tell.
I DO have the NiMH pack for the KX3, and a couple of sets of Eneloops for
it, but I keep them charged up for emergencies.

including those for 2018. The problem is it includes all the other forms

Ken,
Look at your Icom 7600 documentation. I believe the 'keyword' may be
"Send" or Keyout or something of that nature (PTT should be an input to
the transceiver, not an output, but some manufacturers mix them up
causing confusion - check the documentation).
Connect that output from your transceiver first to the KAT500 AMP KEY
connector and from the other KAT500 AMP KEY connector to the KPA500.
That allows the KAT500 to disable the amplifier keying if the KAT500
needs to tune.
You should then be "good to go" with the basic cabling. When you get
the proper cable, it will integrate better with your Icom, but the basic
cabling will get you on the air with your new toys.

You must measure the batteries under load.? The no-load voltage is almost
meaningless.
You must use NiMH batteries in the KX3 if you are using the internal charger.?
The best way to test them is to use an external battery charger built for RC
that accomodates NiMH chemistry, and can both charge and discharge multiple
cycles, and has a top-off low current cycle built in.? This will balance the
pack.? Take the batts out of the kx3, put them in an empty battery holder, and
run them through three charge/discharge cycles.? The charger will show their
true capacity.? Running several cycles will build up their capacity a bit.? I
use only Eneloops.? Regular NiMH batts can lose all their capacity in a few

All batteries have a finite life.
I am sure others will disagree.? This is my (considerable) experience with
NiMH.? YMMV.

Eric,
The KPA500 (like all other Elecraft transceivers and amplifiers) uses
all electronic T-R switching which is very fast and there is no
"hot-switching"
The K2 Keyout to start of RF is fixed at about 12 ms. The QSK Delay
adjust the trailing hold time for the Keyout after keyup, not the start
delay. You can run with the KPA500 set to the default of 4ms.

Eneloop Pro (labeled Eneloop XX for a bit) are rated for 500 charge cycles.
Regular Eneloop batteries are rated for 2100 charge cycles but have lower

The Wikipedia page on Eneloop has a chart that clears this up to some degree.

Hi,
Just a follow-up.
Put in a new set of NiMh cells and all seems OK. Use of NiMh seems to be a
discussion issue, but over here in Denmark we have a limited range at
reasonable prices. We don't have all the brands and types as in USA.
At least it is working. Thanks to all for their input. Still battling to see
topics after mid-2017 in the KX3 board, not only my own but everyones.

Something I learned from one of our "tech reps" regarding rechargeable
batteries and charge cycles. ?? I have successfully applied his advice
for a multitude of and different types of my rechargeable batteries.
If you use a battery and then recharge it, that is one charge cycle.??
Likewise if you should use only 10% of the battery capacity and recharge
it, that is also one? charge cycle. ? And in the same vein, if you use
90% of battery capacity and then recharge it, that is also one recharge
cycle.
The point, every time you use the battery, regardless of the amount of
discharge, and recharge it, that is one charge cycle. In other words,
don't recharge until necessary. ? And never leave a battery in the
discharged state.? Always charge to full capacity.?? Short charging
cycles, because one perhaps is in a hurry and can't wait, only subtracts
from the total number of charge cycles available.??? And there are only
so many charge cycles with each type of battery.?? So every time you use
and recharge a battery, click off one charge cycle.
I've practiced this with several different types of batteries and find
that my batteries last much longer and need less frequent replacement.

I think Bob is mainly referring to NiMH batteries. I am not sure about
the partial discharges, and whether each one counts as a whole cycle.
That is certainly NOT true of lead-acid and Li-Ion batteries, which will
survive many more partial discharges than deep ones. Li-Ion batteries
should not be stored for long periods fully charged, but at 50-70
percent. Fortunately, their self-discharge rate is so low that you would
have to store them for years before you would have to worry about them
becoming completely discharged, which is bad for all types.

Normal NiMH batteries will self-discharge in a fairly short period.
Low-self-discharge batteries will hold a charge for a long time, and can
be sold as "pre-charged" so the consumer can buy the rechargeable
batteries they want and not have to buy "temporary" alkalines.
Eneloops are considered to be the best, certainly the most well known.

Put in a new set of NiMh cells and all seems OK. Use of NiMh seems to be a

reasonable prices. We don't have all the brands and types as in USA.

"This is good data for those running sound card modes such as FT8."
If you do FT8 right you only need a TX bandwidth of 500 Hz (low 1,500 high
2000). Any more than that is only needed for those who insist on not using
split and more than a few of those are over-modulating and filling the spectrum
with double wide and triple wide audio harmonics.

I had a pair of huge lead acid AGM batteries die on me after a bit over
six years of very light use in a solar panel and battery system.
Consulting the factory, they stressed that the batteries were getting
cycled each day that the Sun came out and the charger started charging
the batteries. I used the batteries sparingly at my remote ham shack,
discharging about 10 to 12 % typically on the days that I used them.
Only once did I discharge them to almost 75% of full.? I should have
used them more so I would not feel so cheated having them die so
quickly.? My solution is to replace them with LiFePO4 batteries and
disconnect them from the solar charger unless I need the batteries for a
specific event.? They can go a few months with no charging.? I can keep
the charge cycles at a much lower rate with LiFePO4. You can't do that
with lead acid, or at least not as well.

I think Bob is mainly referring to NiMH batteries. I am not sure about
the partial discharges, and whether each one counts as a whole cycle.
That is certainly NOT true of lead-acid and Li-Ion batteries, which
will survive many more partial discharges than deep ones. Li-Ion
batteries should not be stored for long periods fully charged, but at
50-70 percent. Fortunately, their self-discharge rate is so low that
you would have to store them for years before you would have to worry
about them becoming completely discharged, which is bad for all types.

If you use a battery and then recharge it, that is one charge
cycle.?? Likewise if you should use only 10% of the battery capacity
and recharge it, that is also one? charge cycle. ? And in the same
vein, if you use 90% of battery capacity and then recharge it, that
is also one recharge cycle.
The point, every time you use the battery, regardless of the amount
of discharge, and recharge it, that is one charge cycle. In other
words, don't recharge until necessary. ? And never leave a battery in
the discharged state.? Always charge to full capacity.?? Short
charging cycles, because one perhaps is in a hurry and can't wait,
only subtracts from the total number of charge cycles available.???
And there are only so many charge cycles with each type of battery.??
So every time you use and recharge a battery, click off one charge
cycle.
I've practiced this with several different types of batteries and
find that my batteries last much longer and need less frequent
replacement.

Eneloop Pro (labeled Eneloop XX for a bit) are rated for 500 charge

The Wikipedia page on Eneloop has a chart that clears this up to
some degree.

According to the A123 data sheet, their LiFePO4 batteries charging lifetime
counted a charge cycle as 100% of capacity, whether you recharged them 25%
four times or 100% once. I can't speak for NiMH.

I think there's something more broken with Nabble, as there are plenty of
posts that include the model number in the title that aren't filtered to the
correct subgroup.
I really wish management would join the 21st century and switch from email
to a message board to eliminate all the useless emails for those of us who
don't own every Elecraft product.

Barry,
Nabble is not controlled by Elecraft, contact the Nabble administrator
about that problem.
The only email group that Elecraft controls is the Elecraft email list
from elecraft at mailman dot qth dot net.
Please *don't* switch to a message board! I can't find anything on
those things.
I have my filters all set up for the Elecraft reflector.

I would guess that max # of charge cycles never comes into play in most Ham
Radio related battery failures. It is more than likely that it is simply
age or abuse. Over the years I doubt if 5% of my battery failures were due
to exceeding the number of charge cycles.

If that charge cycle theory floating around were true, an average car
battery wouldn't make it three years in a commuter vehicle.
Not sure I buy into that as my plain old (cheap) #24 car batteries I use
with a solar charger typically give me over 10 years of service.
