I picked up the inverter at a garage sale and it is old enough and has been used hard enough that it does not have any info tag or stickers on it any where. I really dont know for sure that it outputs 60hz. it weighs about 15 pounds and puts out 120 volts is all I can really tell.

I have been trying to build an inverter (12 volts DC to 120 volts 60 hz. ) by tearing down an old one and trying to copy it. The transformer does not have a number of any kind that I can find. with out tearing this one up how do I find or build one. Any suggestions?

Being an amature hobiest I dont know all I would like to, but I am interested in knowing more about the GPS transmitter signal and if there is a fairly simple detector circuit out there that I could try to build.
