Prototype boards have arrived. I’ll be working with these for the next few weeks to hopefully finalize a line powered PS2 keyboard adapter for the Kenwood TM-D710A. Here are some pics of the proto board.07/14/2011 – UPDATE waiting on some missing parts to arrive in mail.
07/20/2011 – All parts arrived except for the osc. It’s on backorder for at least two weeks.
07/29/2011 – Still no osc. I’m researching alternatives.
08/05/2011 – Finally located something that should work. 2 week leadtime on this part so more waiting.
11/30/2011 – I ‘ve assembled and tested the few boards I had left and due to limited application of this I will be doing some sort of open source release of the project in December for those that want to build one of these and improve the software.
05/02/2011 07:12 AM – The order for the 1.0D board has been processed and passed design checks with manufacture. We all should see boards from the group buy in the next 3-4 weeks hopefully. Parts have already arrived. I’ll be posting more information and documentation during those long 3-4 weeks of waiting here. I recommend to everyone to use an AVR platform for MCU development an interface but you are welcome to use what you want. The goal is to end up with something that is under the 100ma current of the MIC interface. Read more…

The TM-D710 keyboard adapter works. It’s a bit bulky using a AVR prototype board, interconnect and PS2 port. Now that I have that working I’m thinking it would be even better to use the serial port to connect to the TNC. I’m not sure yet if it’s not just easier to use a laptop with xastir plugged into the data port of the TNC.
