KX3 - KXBC3 NiMH Charger

[Doug Ellmore Sr.]

I got back from my Aruba vacation Friday.  It included QRPing at the
beach with the KX3 and buddipole.  Info at www.ellmore.net/na1dx .  It
was a blast!

One of the things I did to charge my 8xEneloop XX 2500mAh batteries
was to charge a 7Ah Battery with a small Sears 1 Ah battery charger
and then use that battery to top off the Eneloops at night.  I also
operated with teh 7Ah battery and went through the aiport fine.

That worked ok, but it would be nice if I had a small AC/DC power plug
in to plug into the KX3 while sleeping or away from operating.  I
guess I could have used the rental car lighter, but didn't have an
adapter.

Maybe someone could source an appropriate SMALL AC/DC adapter for
working with the built in charger.

73 and good DX,

Doug, P40DE, NA1DX

By coincidence, I am also in the market for such an adapter, and found
something that should work at Jameco:

This is a 3A "wall wart", so there should be enough current there to
transmit and charge at the same time if you wanted. If the specifications
are complete, this won't be a super-efficient power supply when nothing is
connected to it (ie, they post no CEC Level), so you'd want to unplug it
when not in use.  If you want something with a higher efficiency guarantee,
they have some "slimline" adapters available with a variety of current
options.  The main thing looks like getting something with a 2.1x5.5
center-positive connector unless I'm mistaken.

Of course being switching power supplies means they could be a little noisy
with a lot of nasty harmonics if they're cheaply made.  I'm not able to
comment on their quality because I haven't tested one out yet.

Saying something doesn't make it true.  Belief in something doesn't make it
real. And if you have to lie to support a position, that position is not
worth supporting.

3 amps would be more than enough to operate.

What I was thinking though was just enough to charge the batteries --
operate on batteries all day, and then plug it in back in the hotel room.

Would half an amp at 14 volts or so do?  Does a little ripple (or noise)
matter if you're only charging batteries?

I just use an MFJ-1317.  13.8VDC at 2.89 amps, it's perfect for both simply
charging and transmitting from, you just need to grab a PC power cable to
connect to the other end.  You can also use the MFJ-4103 (which is the same
as the 1317 but also includes a Yaesu FT-817 adaptor which I believe is
removable).
