Thanks to Kevin @kb9rlw the MxP50m Amp is now working with Rs-918. A transistor, diode and a resistor was added on a protoboard. Now the radio only need to sink 1mA instead of 40mA! Check out Kevins Youtube channel for the instructions. #mchf #rs918 #mxp50m #sa6bwx #qrp #electronics #hamradio #hamradiouk #amateurradio #kb9rlw
