Hello Evan
As told, my radio (v5) did work, but intermittand. The sensitivity was very, very low. I've been aligning during days, and days, and days...
Today I once more checked the receiver. Audio part: ok. 11 MHz to test points 16 and 17: nothing happens. Than checked TP18 with a 50 MHz oscilloscope: a poor 11 MHz signal, some 50 mVpp, very distorted. Same on pin9 of the Raduino board, and the right hand side of C4. Beautiful 11 MHz (600-700 mV sine) on the left hand side of C4 (oscillator chip side). Removed Raduino from the chassis, checking C4 with?magnifying glass: is was broken (see pic). Replaced it with a (wired) cap, and yessssss: it was clear by hearing the noise already, the miracle happened. Could receive FT8-sigs on 7074 USB with my finger as antenna...
And now finally for the alignment !
Thanks once again Evan !
