Apologies all - it was D109 not D108.

Anyway, good luck Robert - if it's just D109 it should be a easy repair. I've ordered a bunch of them for um, future use.

I was actually convinced my MCU was dead - so a nice surprise when the rig came to life! I haven't tested it properly yet - that will be after I reinstate all the LPFs and BPFs.

I forgot to pass my thanks to others - there are a lot of posts re D109 but the one that prompted me to check was from Paul G0TXL - so thanks Paul and everyone here for that matter - it's great to have the group as a resource, and for me essential when fault finding!
