[Elecraft] K3 and inverter generators

[dave]

I can't comment on that specific generator. I do have some experience 
with inverter generators. In one case, a Honda 1 kW used at FD, there 
was no detectable noise from the inverter. But a friend has a 3.5 kW 
Honda that he uses when RV'ing and it is terribly noisy.

The ARRL ran some tests on generators, June 2012 issue. They show 
graphs for RFI produced by the generators tested. All look fairly noisy.

Based on their tests and my experience I would suggest that you expect 
quite a bit of RFI from any inverter generator. Not all make RFI but 
it appears that most do.

If it produces adequate power for your needs you might want to look at 
the little 2 cycle conventional generator at HF sells. I have one of 
those and it is absolutely RF quiet. Have used it for 2 FD's with no 
issues. It makes higher ambient noise, but no RFI at all.

Another option would be some filtering on the AC line from the genni. 
The ARRL review includes some comments on those as well. But even 
after filtering the emissions were >20 dBuV. Seems to me this level 
would still be heard.
