Perhaps it's vanity, but I like running my rig off solar power
and batteries. Since I also take the rig out in the field
somewhat frequently, battery power avoids noisy generators.
(Besides, I own the panels and batteries, but don't own a generator.)
In any case, floating batteries requires a power source during
operations which doesn't work really well with solar power at
night. The WVARA operation discovered during the last California
QSO Party that tired batteries and K3s are a recipe for
transmitter distortion and local interference in a multi-radio
operation. The N8XJK Battery Booster is an attempt to get more
life from tired batteries into the just before dawn hours.

Well my take.....ANYTHING between the power source and radio
has resistance, regardless of how small. Resistance with any
amount of current equals voltage drop. Thus E = IR Where E
is the voltage drop, I is the current and R is the resistance.
I'm not sure what some of those thing are nor why they are
needed but I do know least is best. As to operating from
batteries, floating AGM batteries at 13.8 should not produce
any voltage drop other than the resistance of the power
cable. Of course a fuse or switch in line does have R so
there goes the regulation as current changes. Nothing is
better than a good regulated supply and hopefully one with
remote voltage sensing. Of course those are more expensive
and more of a challenge to install and then have operate
correctly in the presence of a RF field.

I gave up running my K3 through a RigRunner for just that
reason. I put in a short lead directly to the battery bank APP
junction strip and things got a lot better. They got even
better with a N8XJK Boost Regulator between the K3 and the
junction. (Tested with 100W into a dummy load.)
