A little background
I was given a bitx 40 for a gift from my brother. I'm a tinckerer? by nature so this makes sense. However, electronics are kind of new to me.

Since this will be my first HF rig I opted to do a clean build. I ordered a model II case from amateur radio kits. The kit is cut to use a baofeng type ptt mic, the kit also has a gain control. It came with 10k pots x2, and a 100k pot. I. Not sure what pot goes where. I'm also not sure how to wire in the gain control. Can i get some guidance.?

Thanks for the help.

Sunil's got lots of cases to choose from, for both Bitx40 and uBitx:

Here's the "Universal Case Blue II for Bitx40":
? ??

Packing list shows "10k LIN Control x2" and a "Push to on switch x 1"
The front panel shots show main tuning, audio gain, and mike gain with matching knobs provided.

From that I'd guess he is supplying pots for mike gain and audio gain plus a power switch,
The audio gain with integrated switch from hfsignals is not used because the shaft is too small
for his matching knobs, it is replaced by one of the 10k pots plus the switch.

I assume the other 10k pot is for mike gain which is not a bad idea.
No additional parts for hacking in a mike gain, and perhaps no instructions for how to do so.

No indication of a third pot of 100k in Sunil's packing list.? Such a pot would work for main tuning,
but the 10k pot provided by hfsignals for this should be sufficient
since it has a standard 1/4" shaft on it.

Anybody else have one of these Version 2 Bitx40 enclosure kits?
Did you wind up with an extra 100k pot?
How did you wire up the mike gain pot?

I suggest you use the pots as I described above, so you may have a spare 100k pot from
Sunil and a spare audio pot from hfsignals.??
Wire it up as per the hfsignals webpage, leaving out the second 10k pot from Sunil for mike gain
till you have it working.

All vague conjecture, Sunil may check in here and give some real information on this.?
