Hi, all.

I know we have discussed similar topics before, but I have an issue in my RV 
that is now affecting my HF set-up big-time.

Specifically, there is a built-in charging unit for the house battery that 
seems to be creating more and more interference on the HF frequencies.  The 
interference occurs when the charger is in either the "use" or "store" mode. 
I know that the charger is causing the interference, since when I switch 
from "use" to "store
", the interference goes away for a few minutes, until the charger re-sets 
itself, after which time, it gradually returns.

When we unplug the RV from the electrical service at our camp site, the 
interference disappears completely.

As far as I know, since the charger is directly wired into the RV, there is 
no way to turn it completely off.

Does anyone have any simple remedies for me to try in order to get rid of, 
or at least lessen this interference.  It is so bad that it makes the 
40-meter band unusable, which is why I was not on Saturday's round table. 
20 meters isn't much better either, which is rather discouraging.
