[Elecraft] KXPA100 on battery.

[Don Butler]

I have done a fair amount of portable operation with a KX3, KXPA100 and
CrankIR vertical using a 12 v deep cycle battery .... and have ALWAYS had
issues when I try to run 100 watts even when the battery is fully charged
.... the battery just doesn't have enough ..... so I back the power down to
50-60 watts and it does just fine .... personally, I'm happy to have the 60
watts so have not considered it to be a problem.

I just purchased and put together a KXPA100 Amp. I want to use it at home
with my power supply (same one Elecraft currently sells). But I also want to
use the amp with my KX3 out of doors in a portable situation.
I tried my KXPA100 with my 12v 22ah battery and I received a "LO SPPLY"
message on my KX3 along with the bottom right reading "PA FLT". Go in touch
with Elecraft and my battery is not up to the task of giving my
KXPA100 12-15amps. I will recharge my battery and try again.

 

Question: Will a voltage regulator like the N8XJK Super Boost regulator work
and or work well with my KXPA100? Does anyone use their KXPA100 portable
with a battery?
