[Milsurplus] instrument inverter

[Ray Fantini]

Thanks for all the response on the inverter question, but thought I will explain a little bit about the project so far. I have been using a oscillator driving a 125 watt Bogen amplifier with a transformer from the 70 volt output to get 115 400 cycle. For no good reason would like to try using the twelve thousand RPM inverter just to see how difficult it can be. Expect the inverter to only run when changing channels on the transceiver, the servos and amplifiers are way to noisy to keep on all the time so now want to have a noisier inverter just to do it. The real question is how long will it take to spin up to speed and reach 400 cycles? Do you have to have a regulated supply for the inverter input? And just how much noise will this thing make? Perhaps the only answers will be obtained by going forward with this project. If this works out can take a giant leap backwards and use the original dynamotor for the transmitter power supply.
Is anyone using a original dynamotor for a ART-13? On the 618S the dyno only runs when you key the transmitter, do the ART-13 or ARC -1 dynos run all the time they are on or only when they are keyed?
