We picked up a bunch of these on eBay a few years back for cheap - small, "promo" voice recorders for about $2 each.
You might remember us wiring them up to a fishing alarm...
Now we are going to wire them to the HAM radio. The wires are for Ground and Playback. A few more wires and we can record, playback, and tap directly into the Mic and Speaker lines.
Stay tuned...
