BITX40 Hand Microphone
thingiverse
Hand microphone containing PTT button, speaker and microphone. I had great fun with the BITX40 transceiver kit from hfsigs.com, but didn't like having the PTT and microphone case-mounted. Added a speaker as well, feels more comfortable than headphones. My build here connects to the BITX40 with cat5e ethernet cable and a DB9 connector pair, works well but the ethernet is keen on curling up. You can tune the knobs at the start of the .scad file to your components. I used: - the microphone from the BITX40 kit - a storebought 66mm diameter speaker (8 Ohms, 2W, labeled "MLS3") - a storebought case-mountable push button (10mm) - cat5 ethernet cable going to a DB9 connector - 4x M3x10 bolts to mount the cover - hot glue to keep the microphone and speaker in place
