The reason no-one seemed keen is that the OP's **complaint** was that
his 5th harmonic BP filter didn't produce any output.

Eh?? Where did you get that from? I haven't even tried filtering yet!
I still haven't exhausted all the other suggestions made during the
course of this thread.

I think we have to supplement 'Read The Fascinating Manual' with 'RTCT'
- 'Read The Copulating Thread'.

Perhaps you should...

Errr... I read the thread. And in your first message you say. "All I
can get apart from the fundamental is a strong third harmonic on 10.32Mhz,
regardless of what I tune for. I've tried passing the osc output through two
successive inverter gates to sharpen it up, but still nothing beyond the third
appears after tuned amplification for the fifth."

If I'm not mistaken, "tuned amplification" IS "filtering".
