I've been admiring my bitx40 for a while, nice looking board.
Finally, I knuckled under to build it and found a couble of problems.
?
1. no mike.
?
2. One standoff has no threads - it happens.
? ? Furthermore, it?could use about 2x as many standoffs. (The Radino should not be connected solely with ribon cable.)
?
What do I need to do?

scrounge whatever hardware you can for assembly.? if you don't like this plan, there are several fine suppliers of cases aka enclosures available.?

if you have a 'surplus. electret based microphone - try it out.? I am using something once used with an HT I no longer have.? use a search engine here or on the web to see what others are using with the BITX.? Pacific Antenna in US has a microphone kit for these rigs - but its nothing you can't homebrew from the electret microphone furnished with the kit or available on ebay etc.?

do enjoy assembly of the fine rig.? the beauty is having it your own way as you assemble it, and a wealth of ideas from a world-wide community of builders.?

Martin,
Just to double check, the mic is just an electret mic like the picture below.? I don't have one in front of me to measure but it is approximately 10mm in diameter.

I took the electret unit that came with the bitx 40 kit and the push button
and mounted them in a piece of 3/4 pvc pipe and it works very good.?
Mine also had a standoff with no threads. The bitx 40 works extreamly well.
Good luck.? Dave? kc2ipx

Hi
get a long bolt, use a nut washer and spring washer to fix it to the case, then use another nut etc adjusted to the level of the other standoffs and use another nut etc to lock the pcb.
