Hi John,
I also get a subtle humm in my new Standard Horizon DSC equipped VHF, and
this disappears as soon as the charger is turned off. I assume that some of
this ac ripple is on the DC lines as well. I plan to twist the 2/0 dc wiring
together from charger to batteries (should help cancel induced common-mode
noise on the DC lines somewhat..should-a done it when I installed the beast
actually).
