Orion Power Supply Common-Mode
Choke
Installed an Amidon
FT-240-77 ferrite toroid as a common-mode choke (11 turns) in
the Orion's DC power supply cable and located about 18" from
the Orion. I am using an Astron RS-35A linear power supply
(the fan on the Ten-Tec switching PS was too noisy). The
cable run between the power supply and the Orion is somewhat
lengthy because the Orion is connected to an MFJ-1129
multi-outlet strip.
