The antenna is a 96 foot doublet, fed with ladder line. It’s about 55 feet
above ground, so about 52 feet directly above the Alinco.
I also have a club switch mode supply, the MFJ4225 that I will make a test on
soon. It won’t be as easy to check out, because the switching frequency isn’t
adjustable. I might try showing it under different loads to watch where it
shows up.
