Is there an electronics engineer on the forum? Please email me - I'm trying to answer a question that pushes the boundary of my own expertise.

Hello Hugh,
we meet again. If I can help maybe, if not I can fire a query at MERG on your behalf.

Hello Hugh,
I replied to your PM, but I'm not sure if it was sent correctly as I don't appear to have got the copy I cc'd to myself. If it doesn't arrive please let me know and I'll re-type it.
