I've had several instances where my Icom 7300 produced lower power than it should. The first time the MFJ power supply output voltage had dropped significantly. Since then I've noticed the power drop twice and again the issue is under voltage but in these cases the power supply (Samlex) output is perfect.
Replug Samlex into the Rigrunner and the 7300 output goes up noticeably. Replug the 7300 into the Rigrunner and the output hits max. Not sure why. Connector oxidation or ?
