I think you may have hit on it, Bill. Say it's a pulse-regulated
controller on the battery is on the soft side. BTW -- most solar charge
controllers put out a lot of RF noise. The only good pulsing
controllers I've found are the MPPT controllers made by Genasun.

what's the DC voltage at the battery in RX mode? In TX mode? What does
the K3 internal voltmeter read for RX and TX?
