Hi Martin,

both - the supplied manual on the CD (dont know the version, I have the CD in the workshop) and the latest downloaded version (9.7) show pins 1 and 9 as NOT linked together.

First we tried using the old ATR720 wiring with KRT2-ATR720 adapter that I ordered with the radio, but that didnt work. Then we used the new D15 connector and wiring that came with KRT2, but we got the same result - no speaker output. Only when we grounded pin 12 we got speaker output (pitching and squeeling/schreeching when not receiving and unrecognizable voice when receiving). Now we're stuck again.

Thanks for your help!

Cheers,
Tadej
