I am lucky enough to have a semi-permanent field location from which to escape the potential for my investment in radio to be spoiled by others' RFI. I am interested mainly in operating 10W or less digital modes, with the occasional venture into SSB. I expect the operating pattern to be a day or evening of operating every weekend or so. The site is not (audio) noise sensitive, but it is preferable I keep noise to a minimum. I could go solar, have a small test PV system at home, and no discernible RFI problems, though I may not be able to place TCVR and PV quite so far apart in the alternative site. At very close range, charge controller RFI is moderate. I can only really install a maximum of one 250W panel, but I could partly make up for that with a large capacity battery. Or I could go with a small petrol generator. I am at the point of preferring this because it offers longer operating potential. But I wonder what experience people have with 'pure' sine wave inverter generators. Any RFI problems? Other problems? Typical lifetime of generators, assuming regular care? I'd be interested to hear from those with lots of practical experience, especially if you are in a less than a sun-drenched desert location!
