I must agree about the Honda, I used one on FD, and never even heard it
RF wise...  

I must respectfully disagree about testing the HF product, I would not
connect anything worth more than fifty cents to a HF generator for fear
of damage to my rigs, power supplies, etc.  

I simply do not trust anything more complicated than a screwdriver if it
is from HF.

We're at 27 posts on this topic since this morning. Time to close the thread as
we are well exceeding the single topic limit.

Please try to self moderate a bit more. 5-10 posts on most topics is more than
enough and helps relieve email overload for others.

73,

Use a switching power supply with the generator or any other questionable AC source. They gobble up unstable AC like no one's business. 

Take care,MarkAA3K

 Have a look at this video  its pretty good from ARRL on small
inverter generators.   the filter part is the key.

I would not cheep out however   get a cheep generator and it might do
you for a few years and you end up having to get another one
spend good money on a Honda or Yamaha and you have one for life.

we use an inverter generator for Field Day 4A+Gota and VHF  running
various rigs and a serious selection of power supplies both linear and
switching.  including desktops for each station    its either been a
Honda  2800W inverter or a Yamaha 2400W inverter  both have noise
filters at the generator and a ground rod at the generator.  so noise
has not been an issue.
