Thanks Don and David for spending all the CPU cycles on my problem! It turns
out the 2V drop was due to operator impedance - or a loose nut behind the
controls, etc., etc. I was indeed monitoring the internal battery voltage
instead of the external battery. {heavy sigh} So, now I’ll go back to my shack
and ponder my ignorance for awhile.
Thanks again to everyone that took time to read and/or respond.
