GD,

QCX 2017 / 2 #2306 - worked vy well with abt 3 Watts until ....

In QTH TA3 2019 suddently no transmit.  But not the PA Transitors (changed and OK).

Today removed Q4 / Q6 (and supplied precision pins for plug in them) and checked.

Pin 16 of AtMega  keeps always low also by  keying.

ATMega broken ?  - Also Display is broken (tested on Arduino)

(Cannot here make a first flashing on a fresh ATMega - missing C for the circuit )
