blockquote, div.yahoo_quoted { margin-left: 0 !important; border-left:1px #715FFA solid !important; padding-left:1ex !important; background-color:white !important; } Since you are only using one pre-amp at a time, and presumably feeding the DC into the line through a choke, I wouldn't expect there to be an issue. I have pre-amps from the same company that I power through my IC-9100, so they are both running off the same supply via the rig. No issues.

All:
I'll be installing new SFH-Elektronik preamps along with Bias-T's to run DC along the coax. I'd like to feed each preamp with one power supply, but I was wondering if this may cause RFI issues? The power supply for the preamps will be separate from the rigs power supply.
Thanks
