The so-called sine wave coming out of the inverter will be full of
harmonics. The extension cord could make things worse since it would
radiate these harmonics. Again, why go from 12VDC to 117VAC and then
back to 12VDC? If you really insist on going the inverter route, look
for the buzzwords "pure sine" and get the lowest harmonic distortion
unit you can find.

Still, I'm baffled why anyone would use an inverter. You have gone from
perfection (a battery) to a less than clean power.

Hello Junius,

The unit probably would generate noise if one placed it near the radio.
But why would anyone do that? ANY eectrical generator will generate RFI
if a radio is placed close to it. SOMETIMES one has to use common
sense! (That's why they invented extension cords.)

Best,
