I finished the last module for the HF side of my radio control box. This is the audio interface for digital modes. It's joins the keyer and audio breakout board.

And now I have a battery box to power the radio box. This was a much simpler build than the radio box. It's just a 15 AH LiFePo4 battery in a plastic ammo can with fuses, a power switch, and a voltage display. I added a switch to turn off the voltage display. It doesn't draw much (the datasheet says 12 mA), but it's bright and redundant with the display in the radio box itself.
My ham radio box is almost complete... just a bit left to wire up inside the control box. The control box will reroute some of the back panel connections to the front (and vice-versa), switch the mic between radios, switch between speakers and headphones, and contains an electric keyer and computer audio interface.
After much procrastination, I've finished building my TR-35 kit. Next up, a portable antenna to go with it.
I recently got a Kenwood TK-780 mobile radio for the Jeep for Search and Rescue. I did a poor job wiring my first HAM radio up and had a lot of trouble with engine noise, so I decided to rip everything out and start from scratch.
