[Elecraft] OT: Battery and charger recommendations for 50 watt solar panel

[n6lrv at outlook.com]

I haven't observed any RFI from the Morningstar Prostar but then my small solar setup isn't close to any antennas. I'll give that a try and let you know what I find.

What can you tell us about RF noise from the Morningstar charge
regulators when the wiring between panels, regulator, and battery is
very close to antennas? I'd be willing to bet it varies widely from one
regulator family to another.

Another critical point -- current drawn from the panels and fed to the
battery is pulsed DC, so should be viewed DC 100% modulated by DC square
waves. ALL wiring in the charge path must be twisted pair to minimize
radiation from it to nearby antennas.
