Hi everyone.
Has anyone any experience or suggestions on replacing an aging internal K2
battery (the standard lead-acid type) with one of the newer, lighter and
more energy-dense batteries? I know there were some safety concerns with
lithium-based batteries early on, but now that they are are
was
close to resonance or even estimate its input impedance, as measured at the
K2 antenna connector. Can I measure the antenna SWR and bypass the ATU while
I am doing that, to get at least an idea?73 - Kristinn, TF3KX

can we run some other tests to verify if it is actually the mike rather than
something else?

differences between, say, KX3 and K3? Not only in terms of technical specs
(IMD, etc.), but also the internal structure (both with similar RF/DSP
architecture?), features, etc.?

Somewhat less protuding knobs, as well as a thinner dial knob would be more
balanced with the rest of the unit, and would also be less vulnerable for
transportation.

Running two rigs is better and safer than only one.

to the notion that no more than 5W

At any rate, this brings me to the question: If I adjust the power level of
my K2 to, say, 5W, using the power knob, will the rig then actually send out
SSB at 5W PEP, 5W average, or something else?

The choke you already have is the right one. I came across the same
problem, contacted Elecraft and they confirmed that the green body version
of this choke has the orange stripes look more like brown. So, I went ahead
with my green body choke and it works perfectly.

no signal is present, and I do not get the S-meter quite up to
full scale when the RF gain is turned fully CCW.
If I am correct, this is due to the low 8V and that would be an incentive to
get that voltage fixed.

Great!
Are there any photos available, showing the 1- and 2 pocket design? Or
outer dimensions? My interest is a carrying case for the K2, with one or
two pockets (for a small mike, key and bundle of antenna wire).

My questions are...
- Wouldn't the low 8V level be the cause of the above symptoms (a) and (b)?
- Any reason I should or should not replace that 8V regulator, anyway?

I plan to get a local replacement for the 8V regulator, just in case. But
does anyone have comments on the low sensitivity? Would the low 8V level be
