Also, the Behringer HA400 is a 4-way headphone distribution amp for $25.
Basically some op amps, volume controls, and jacks in a box. Other companies
make pretty much the same thing for the same price.

The KX3 specifications say 8 V min, 15 V max.
The most recent firmware update supports 10 W output down to 10 V.

8 W on 6 m would suggest a KX3. The KX2 does not have that band. 8 W is the
spec’ed power out for the KX3 on that band.

I think it is really cool that Elecraft documents these internal receiver test
points. I’m sure they exist in other radios, but they are undocumented,
factory-only readouts. Does any other rig display PA temp, let alone oscillator
temp?

No need for extra batteries for a weekend trip. For a week trip, just take

Right, an NVIS antenna is effectively a Yagi pointed at the sky. So put a
reflector on the dirt.
The Loma Prieta was a 6.9. The Cascadia area could produce a 9.0. Richter is a
log10 scale, so that is 100X as strong.

wire antenna. For example, if you are
primarily communicating with Roseburg, then a 40m wire beam or “ZL special”
phased beam might work well.
One bright spot about widespread power outages—you won’t have much RFI! That
could allow working with much lower power than usual.
