Another version of my 472kHz transverter (G8AGN)

Emeritus Prof Barry Chambers G8AGN from Sheffield (more usually a microwaves and nanowaves operator) has just sent me a couple of photos of his version of my 472kHz transverter that he's just finished. Unlike me, Barry sensibly put it in a decent sized aluminium box which will help reduce heat affecting the LO frequency stability.

I've lost count how many of these transverters, or variants thereof, have now been built but there must be a good few in use around the world now. I have still to box up the 137kHz version which was used a few months ago to span 250km with just the earth-electrode antenna.
