The people at http://www.innovatronix.com/cgi-bin/...alog/index.asp are marketing these power inverters to run studio strobes on location, which implies, though they don't actually say so, that they run off a vehicle battery and supply ample VDC for the studio strobes, which require recycling large capacitors as rapidly as possible. My interest would be in using an 12VAC inverter to supply 13VDC voltage for my NRD-525, in hopes of eliminating power line noise (as well as powering several potable, battery-operated radios). From what you guys are telling me, either a linear or switching power supply would work, but filtering is the critical factor. (This isn't a big priority - most noise at my location is radiated noise.) Greg Why all the riggamarole? Why not just run the radio off the aforementioned vehicle ballery? I was considering a more permanent power supply to run the radio at home independent of the house wiring. So, I wasn't considering using the Innovatronix inverters, but their description lead to my question about "sine wave" (prob meaning "linear") vs switching power supplies. Also, I thought the Innovatronix gear might be of some interest to the group here. I guess I wasn't too clear.
