I bought Yaesu FTdx101D 14 months ago. I like it so much I bought an FTdx101MP about a month ago.
I tested the MP for overshot on the first CW character.I used a Tektronix TDS2012B oscilloscope. The radio is connected to a dummy load. I put a T connector in the cable so I could capture the signal on the scope.
I took four pictures on my cell phone and posted the pictures to QSL net. The trace show no overshoot.
