With the Elecraft upgrade kit shipped to the UK costing over $20 for a
100 uH choke and two surface mount resistors (yes I know there are 4 in
the kit and two axial ones), I wound a choke and used two surface mount
resistors from my spares/repair kit. For anyone who is struggling to
justify buying a slim RF choke to fit between the K3 RF board and the
cover plate (needs to be no thicker than 0.275"), I made a 100 uH choke
using 15 turns of enamelled copper wire on a FT50-43 core and covered it
with clear heatshrink. I cannot really say the audio sounds any better
on my bookshelf speakers after changing the choke, but at least it
didn't cost much...

A UK-based business will soon be able to supply the recommended chokes and
other components. It should be of benefit to K3 owners in both the UK and
EU
so I'll post details on the reflector when available.
