You are absollutley NUTS to offer it for $20   ASSEMBLED.   That is very little over what the  PARTS cost us.   

never again will I solder one together----I'm just ordering from YOU!!!! 

Because there is a ground plane, you may even get away with not enclosing this, but you'll do better if you just screw the board to a small piece of wood (or double-stick-tape to some cardboard) and put it in a small tea tin or something.   I found tin boxes for $2 each.

If you make the TX gain ccontrol a 500-ohm panel mount, you'll have much better control of the TX signal....  That's what i do for HF.  For VHF, the little trimmer works fine.   

i use the $5 Adafruit 1475 cound card, and I literally drill a hole and solder the wires to the right places, after I pop apart the white plastic, of course.   See here:​  They are not great soundcards,,,,but they work.
