I purchased one unit from Costco. The price was $99. The unit was surprisingly light in weight compared to my old transformer-powered 400W u-wave oven. I found no RFI problem from 50 - 550 MHz. The rating is 1300w, which is most probably the DC input power to the magnetron. At 120V, c. 17A of current is drawn. If a SSB amateur radio amplifier was built using the Matsushita switcher PS, two units are probably needed. By putting the 120V inputs to the two switcher supplies in series, operation from a standard, 240VCT, 20A outlet would work. I have not yet disassembled the oven to measure the HV. Does anyone know what's the typical range of potentials used to power magnetrons of this size? tnx
