I think I removed the last of the RFI from my station DC (voltage and
current) monitor system...
I added:
1) one clip on toroid to the current sense, voltage sense and ground
wire bundle - 2 turns fit in the core.
2) a ring toroid to the power cord of my transceiver (removed the 3 clip
on toroids) - 3 turns fit in the ring.

Suggest treating every conductor that enters or leaves your charger
with a large and appropriate core of ferrite material. Choose the
ferrite for frequencies in the lower HF spectrum. 75 material would
be a good choice. Take several turns through each core.

I don’t have much RFI in my shack and it seems like everything is
working pretty well.
The one thing I have left to fix is that my DC power system which
has a power supply that charges the backup battery, the battery
powers radios and other stuff and has a monitoring system with a
high current shunt and a volt meter.
When I transit on 40 and 80 something gets into the battery
monitor and it goes crazy, flashes the display, etc. When I stop
the transmission it goes back to normal so it’s not damaging the
voltmeter.
What I want to do is to bypass or filter or someway get rid of the
RFI that’s getting into the current reading shunt and or voltmeter
of my battery monitoring system.
If you have you any insight I would appreciate it.
Thank you,
