Dave; how I test radios in my shop is to just hook up wires as the factory made them. I have a bunk radio with two leads off it, pos and neg, with alligator clips. I have a used speaker or two of various ohm ratings that I hook up and an antenae also. Pay attention to the ohm rating on the radio in question. I don't have any grounding issues as I use the stock set-up. One corner of my shop is set up as a test bench with all kinds of test leads hanging on a nail, and a nasty 10 year old battery serving as the power source.....Russ ____________________________________________________________________________________ Never miss a thing.
