Phil,
The DL2 has an included diode detector which can be used in conjunction
with a DMM to measure power accurately. and is not very expensive.

Phil,
Those optional tools are for those who are not satisfied with the
default settings - in the case of the 50 uV signal generator, it will
allow you to set your S-meter at the S-9 point. My K3 was 'right on'
with the default settings, but since I have an XG2, I checked it anyway.

I didn't use the optional tools when building my K3. I really don't need
to have that degree of precision. Just build it and enjoy it.

very close, but with the added instruments, one can achieve a higher degree

Don and Chuck,
Thanks for the explanations. I will probably get the XG2 kit just because it
is yet another kit to build but I doubt that I will get such a meter. Well,
maybe I will if I can find a cheap working on somewhere. No rush though. I
just realized though that I doubt that I have
The Elecraft dummy load DL1 can be used as a watt meter, using a DMM.

Sometimes learning to achieve greater precision for its own sake can be an
enjoyable and educational pursuit, even if it makes no significant
difference in how the rig performs on the air.
And then there are the occasional Hams who are using their rigs in a special
way that wants greater

The K3 Assembly guide says that you would need a accurate power meter measuring
1 mW to 5 W. Also, a signal generator calibrated 50 microVolts output at 20 or
40 meters. I have a signal generator that goes up to 5 MHz but I am pretty
certain that the voltage adjust does not go down to 50
Phil,
Note that those are optional - not required, but they are useful if one
wants to do the precise adjustments - the default settings will give you
a fully working K3.
The Elecraft XG2 has a 50 uV output level, look at the Mini Kits.

Don,
Thanks for the pointer to the XG2 -- yes, that is what I was trying to think
of. About them being optional, I did see that but I was curious as to what
what gains by the precise adjustments. If the default settings give you a
fully working K3, what is being done by those who are making
