[Elecraft] K1 with internal battery

[Sandy W5TVW]

I originally ordered my K1 with the internal battery accessory.  Didn't like the little speaker at
all compared to the larger one.  Also the cells were a pain in the butt
to install and remove for charging.
I never thought about leakage, but that makes a lot of sense!

I use a 10 cell holder with 2 A/H Ni MH batteries portable.  Also have
a cheapie $15 gellcell battery pack I bought from Sportsman's Guide
that is super neat.  The two 6 volt batteries in series are around 4 A/H
as I recall.  Pack has a nice shoulder strap, internal 10 amp fuse
(the 5 X 20mm European type) in a holder.  I took loose the
"cigar lighter" receptical and installed a two wire Anderson "Powerpole"
connector on the lead.  Everything I have now That works on a 12-15
volt DC supply has the "Powerpole" connectors on them.  Very convienant.

|
| The "knobs" you speak of are just replacements for the two small screws that hold the K1 top cover
on at the rear.  The KBT1 screws have a larger knurled head that allows them to be loosened or
tightened using only finger force.  The replacement top cover that comes with the KBT1 is held in
place in the front by a lip, so only the two screws at the rear are required.
|
| I removed my KBT1 after having it in place for about 18 months.   I didn't like the looks of the
KBT1 top cover and the sound of the micro speaker attached to it, compared to the original cover and
speaker.  More importantly, I don't like a source of potential chemical leakage from batteries
inside the K1's case.  There is no physical barrier around the KBT1 AA-cell pack that will retain
leakage from a cell.  I much prefer to use a small external 10-AA cell pack rather than the 8-AA
cell pack of the KBT1.
|
| The KBT1 should have been made easily removable so that the compromises associated with having it
installed need only be suffered when absolutely needed.  The KBT1 *should* attach via a cable with a
polarized two-pin female connector to a male connector *anchored* on the RF board.  This would allow
easy removal at any time.  The current design has the connections made by soldered connections, and
even if you jury-rig in a connector in the power leads, one side of the connector will then be
floating around creating potential shorts when the KBT1 is removed.
