Re: [Elecraft] KX3 Grounding & NiMH Batteries

" Looking for suggestions on some type of quick connect/disconnect for a
ground to the chassis of the KX3 instead of having to loosen a thumbscrew
each time. "

- I would simply leave on the thumbscrew a small bit of wire  with a banana
plug on the other end.
- Anyway, KX3 on batteries can sometimes work "floating" ; it depends on
your antenna setup.

That's also what I do with all my gear -- stranded wire crimped and 
soldered to a spade lug on one end and soldered to a PowerPole on the 
other. Then single conductor power pole jumpers of suitable length from 
one piece of gear to another.

[Elecraft] KX3 Grounding & NiMH Batteries

[a...@juno.com]

I used Eneloops for years to power multiple camera flashes with no problems. 
Recently switched to PowerX batteries of a slightly higher capacity and they 
are doing well too. The original Eneloops (now 5 years old) are still meeting 
90% of their original capacity after numerous cycles. I test them all 
periodically with a charger I can also recommend:
http://www.amazon.com/La-Crosse-Technology-BC1000-Battery/dp/B004J6DLD4
and with the CBA analyzer from West Mountain Radio.

Either brand battery should serve you well.

An interesting read:

Re: "...is there one type of NiMH batteries to consider that might be 
considered the best?"

The term "the best" is always a difficult one for engineers, but I still have a 
three year old set of Panasonic 2000mah low self discharge  (LSD) cells in my 
KX3, and they are still working great.  The chemistry in these is identical to 
the Sanyo Eneloop cells, which are available in at least 2500mah LSD cells now. 
 Panasonic  ended up buying Sanyo, but maintained and continued to improve the 
Eneloop line.

One caution with any rechargeable cells is don't discharge them below their 
minimum discharge voltage, which is about 1 volt per cell for NIMH cells.  The 
KX3 battery warning and shutoff will protect them nicely.

Don't even consider cells that are not LSD cells.  Those will self discharge to 
a voltage below their minimum discharge voltage, destroying themselves in the 
process.

Re: [Elecraft] KX3 Grounding & NiMH Batteries

If you do not use the 2 meter module you can do as I have and use the hole
in the case for the 2 meter antenna. I used star washers to bite into the
metal and have a 1/4" or so of a small machine screw sticking out. It does
a great job of grounding the rig.

Re: [Elecraft] KX3 Grounding & NiMH Batteries

[Lynn W. Taylor, WB6UUT]

I bought high-capacity NiMH batteries for my KX3 and they were nearly 
always dead.


I replaced them with "pre-charged" (Low Self-Discharge) cells, and 
they're always good.


The choice is easy.

Re: [Elecraft] KX3 Grounding & NiMH Batteries

[Tim Henrion]

There are two types of NiMH batteries, ‘regular’ and Low Self Discharge (LSD). 
LSD NiMH batteries have 10-20% less capacity that the highest capacity standard 
NiMH cells but lose much less of their charge over time. I use LSD NiMH’s 
because the charger in the KX3 has to be enabled manually and doesn’t 
continually top up the batteries. For scenarios where I’d really care about the 
extra capacity, I use an external lithium iron battery pack anyway

The generally recognized ‘best’ LSD NiMH batteries are the Sanyo Eneloop XX 
batteries (the black ones, not the standard white Eneloops which have less 
capacity). They do come at a significant cost premium, however, for the 10-15% 
extra capacity they have over less expensive NiMH LSD cells.

[Elecraft] KX3 Grounding & NiMH Batteries

[TFJM via Elecraft]

Looking for suggestions on some type of quick connect/disconnect for a ground
to the chassis of the KX3 instead of having to loosen a thumbscrew each
time.

Also, is there one type of NiMH batteries to consider that might be
considered the best? Just rec'd my KX3 and haven't bought batteries. I have
been using the Pro Audio Engineering power supply.

Thank you-
