Hello Peter

I would like one board please. PM sent

Ian - G4JQT · 10th Feb 2024, 2:06 pm

It's now been a quite a few weeks since the MiniMod Mk2 article appeared in the BVWS Bulletin and Peter designed and distributed the PCBs through this forum.

I'm assuming the dozens that have since been made all work as expected, but I'm just fishing for any "operating idiosyncrasies" that might be revealed once many examples of a design are running about in the wild!

If so, then a few short follow-up notes may be required. The only thing I can think of is C12, originally specified as 680nF, but later changed to 470nF (as an easier to source value) with no significant change in performance. I missed the changed value on the circuit diagram which shows 680nF, but mention it in the article's text.

By the way, Peter's (M0HYT) TwinMod design is an interesting evolution. Thread here: https://www.vintage-radio.net/forum/...02&postcount=1

Regards,

Ian
