Here’s a new stack of MicroModem PCBs, fresh from the factory. They just arrived today, one day earlier than I thought. Nice surprise! When I initially put up the modems for sale, the limited stock I had was sold out way quicker than I had anticipated, so I apologize for the wait for those of you who also wanted to buy one! I’ll get to testing these boards straight away. Hopefully they are error-free and good to go! I will update the shop as soon as I am ready to send more out 🙂
Yay! Boards are working 🙂 I made a few minor changes to the PCB design, and it seems I didn’t mess up anything. I have just assembled the first board, and it’s working brilliantly. Here’s it is sending out a test. You can see the packet here: http://aprs.fi/?c=raw&call=OZ7TMD-3&limit=50&view=normal (until it’s deleted, packets are only saved for a couple of days on APRS.fi). The relevant change to this revision is the inclusion of a trimpot, so you can now tune the output level of the modem from microphone level to line level! Neat!
