[RFI] RFI affects station Amp / Voltage / Watt / WHour meter

[Mike NA6MB]

I have a Voltage / Amp / Watt / Watt Hour meter similar to the one shown 
from eBay.

Works great except when I Tx on HF.
Then the display may go off or numbers scrambled or all segments on.
I have mounted it in a metal grounded case with ferrites on the leads.
I have one on the voltage sense / power pair and one on each end of the 
current sense leads.

Any ideas on what to try next?
