BitX40 #646 Has Arrived!


 

Well, technically it arrived Friday, but I wasn't able to go to the post office to pick it up until this morning. That is going to be so much fun when I get time to put it together, get an antenna built, and so on...

I am thinking of making one mod almost right away, though. I want to replace the microphone and earphone connectors with a TRRS jack ( - Goes to Mouser) so I can use my cellphone headset with it. It's a 3.5mm TRRS plug, works with my laptop, cell phone, and with an adapter my desktop PC. (I'm guessing to split the + line on SPK1 for T and R1, + line for MIC (not labeled, but I assume is the 2-pin to the right of SPK1) to R2, and combine - on both SPK1 and MIC to S.) I'll probably also get a 10-turn pot and some nice knobs from Adafruit.

My only concerns so far are that C103 appears unpopulated, and L5 next to it is a piece of wire rather than an inductor.

Everything looks good, though, and I can't wait to dig in.
