[amsat-bb] BIas-T Power Supply

[Mark Johns]

 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

73, Tony
