Do any of you have any experience running the older tube-type
transceivers (e.g. Collins, Swan, Hallicrafters) from a 12-VDC to
110-VAC inverter?

I am getting a 750-watt-continuous, 1500-watt-peak inverter for my
motorhome and would like to be able to run something like a KWM-2A
from that.

Is the input waveform important? Will the so-called "modified sine
wave" inverters be good enough (as contrasted with the square-wave
inverters on one end of the quality scale and the big-bucks
pure-sine-wave inverters on the other end)?

Thanks...
