There's no way you're going to run a KPA500 on battery. IMO, power amps
are totally out of place on FD, which I've always seen as a "barefoot"
or QRP event.
We do county expeditions for QSO parties like 7QP and CQP, and run two
or three stations, each consisting of a K3, KPA500, KAT500, and P3/SVGA.
Each station is powered by a Honda 2000i running in Econmode. They make
some RF noise, which must be filtered with a good multi-turn ferrite
choke. Follow the guidelines for chokes on RG8-size cable
(k9yc.com/RFI-Ham.pdf), and place the choke right at the generator.
Commercial line filters do NOT work.
My neighbor W6GJB converted his 2000i to propane, and loves it. Mine is
still burning petrol.

Being there is no better place to get advice than this reflector, I am seeking your
recommendation. I have an Elecraft K3, P3, KAT500 & KPA500.
I want to operate somewhat portable with the K3, P3, monitor and laptop,
buddipole on SSB and digital modes on Field day, and demonstrations on outings
to community events (like festivals, etc). My options, I’m considering are:
1) Honda 2000i gasoline generator
2) Yamaha EF2000iSV2 (with propane option)
+++++++++++++++++++++++++++++++++++
1) Deep Cell 12v 100amp battery (brand, model, control charger?)
2) Lipo battery (brand, model, control charger?)
2) appropriate solar power panels and controller charge for either of the above
battery (brand, model, adapters?)
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
My questions:
1) Is it best to go with the generator option; and if so, which of the two
choices above? Any outstanding reason for this option, and choice of the two?
2) Is it best to go with the Battery, and solar option; why? Is there reason
to choose the Lipo over the Deep Cell batteries? I am concerned over the
choices about battery voltages and amp’s needed to operate as stated above.
It’s noisy but the generator option seems on the surface much simpler for
setup. However, from the perspective of demonstration of Amateur Radio today,
the solar and battery option appears to be more demonstrative of the state of
Amateur Radio today. Being 77 yrs old, I don’t want to get over my head in
technology (though I love such).
Thanks for your thoughtful recommendations.
Mike, N8TTR
