While using Yaesu rigs, if you want to use a preamplified microphone or an EQ (like EQPlus or UR6QW) power is taken from the Yaesu RJ45 Microphone. As of today it's not possible to use them without extenal mods to get power.
It would be interesting the control-RRC to provide +5VCC in the correspondent RJ-45 pin.
