So I like hte Idea and  way the mics Tx on the OP3 is shown, but see nothing on the Tx flashing if its working, to take this to  the  Rx side it is also where the spinwheel can  as well be used manually that is left out, in format.  see video to better understand

1 Tx shows no flashing leds at all when formatting

2 Rx formatting  needs tiny fingers to swipe, where hte spinwheel can be rotated  to get he  slider moving, it does not

thank you see video
