Running KPA500 on generators.

I’m gearing up for grid squares this summer. I’m thinking of purchasing a
KPA 500 amplifier. Does anyone have experience running one of them on the
dual configuration of Honda EU 2000 generator‘s?

Neil -

N9FN and I have run several state QSO parties with a K3, computer and
KPA500 from a single Honda EU2000i

Awesome performance

GM Neil,

I regularly use my KPA500 on a generator. This week, I'm using it on a
Cummins 3.5 KW in our RV. One year ago, I used it on a Harbor Freight
Predator equivalent to the Honda 2 KW inverter. It works well on all three.

The only caveat is when operating CW, I needed to avoid using the "Econ"
mode which sets the idle speed much lower. The Honda and HF versions didn't
like the sudden change in current draw and would fault. As always, check
the HV supply reading on the KPA500 to determine if a different transformer
primary setting is necessary under load.

I want to add the KPA500 manual describes the different primary tap
settings. There seems to be a lack of manual-checking going around these
days. The updated manuals (firmware changes) are invaluable tools!
Fortunately, Elecraft allows making notes in the PDF versions of their
manuals (copy and paste) which is much easier to accomplish than in the
printed versions.

73, Bill, K8TE

Same for our group working CQP and 7QP. A single 2000i works great to
run a single K3/KPA500 station. We use Thinkpads for logging. W6GJB
bought the device to sync two 2000i generators, and we use that setup to
run two K3/KPA500 stations. We run 120V.

Re: Running KPA500 on generators.

When we were still doing CQP [Alpine County] from Camp FYNO at 8,500 ft,
we had a Honda 2000i. Outside the contest, it idled all night powering
the electric blankets. During the contest, it would not tolerate either
CW or SSB in that mode.

Quite a few DXpeditions have run in the past few years with KPA500s and
Honda generators. I think you'll be fine.
