Enclosure Construction

I bought this pot off of the QRP-L a few months back. It came with a really nice turns counter, and is narrower, but longer than most 10-turn pots. When I completed installing the Timing Base, I also installed the Fine Tune pot (labelled "optional" on the schematic). Later, I realized that this was redundant since I had the 10-turn pot. I was going to replace the pot with a Zero-Span switch (essentially freezes the timing base on the current center frequency). However, in use, I've come to actually use both tuning pots, so I think I'll leave it. Eventually, I'll replace the Span pot with one that has a built-in switch, to switch off span (turning it all the way down almost does that now).
