I just posted about having a Honda home gen.
Interesting to note what 80m and 20m sounds like when there is a
commercial power outage: normal S5-S6 noise floor drops to S2 (even
when I run my Honda and the "rest of the world" is dark). Years ago
(1980's) I lived off the grid in a little cabin and 80m noise floor
was S0; boy could I hear and work them! Later (1979) the utility ran
wires into my area and noise rose to S3-S4 (those were pre-wifi; now
it would be higher). This was a town of 150 people 50-miles from the
nearest other town.

My goals are to be able to work QRP stations and home stations with
lousy antennas. To do that, you've gotta be nutso about killing RX
noise. Do the math -- the difference between S3 and S6 is 15-18 dB,
depending on whose definition of an S-unit you accept. 15 dB is a 32x
power difference, 18 dB is 64x. 15 dB more noise makes a 100W signal
sound like a 3W signal.
