I had the old Heath Cantenna dummy load. I had it filled with real transformer oil… it later became a problem to get rid of it legally and the thing was kind of messy to have in the house. Kept it in a dishpan.
I will probably stick with my MFJ dry dummy load and the radio’s output meter. On the command-set rig my brother built for me back about 1960. We were in central Louisiana. Tuneup was into a lightbulb. Antenna: a piece of frayed lamp cord tied to the light fixture on the ceiling. I sent out CQ and my new novice call: a few days later a QSL card came in from Connecticut with a signal report!!
