During our Field Day 2008, we experimented with many power options. Since it is a well known fact many UPS devices are not compatible with the power generated by certain generators, we will report the combinations that work.
The “APC Back-UPS ES 500” runs just fine on the output generated by the “Honda EU2000” generator.
We used this UPS to power the computer running as logging server for the N3FJP software as well as the Linksys WRT54G router.
