A point similar to Mark's that I've noted: PTT placement. I'd venture most cabinet/housing layouts will have the PTT closely associated (if not integral with) the Mic connector/socket. Myself, I have a wire draped across the PCB from the PTT connector to the Mic connector, then intertwined (twisted) with the Mic wiring (from the as-provided Molex plug) to the (as-provided) 3.5mm stereo socket. I have PTT to Tip and Mic to Sleeve, and the companion Spkr socket similarly Spkr to Tip and Mic to Sleeve. This will end up as 2 sockets below/near the Vol control. PTT-and-Mic will work for a hand-mic along with Spkr/headphones for short overs (/ contesting?). and Spkr-and-Mic for a headset with separate (push-push toggle) PTT (mono plug?) for 'rag-chew' (or Key for CW?). Versatility and usability ... :)
So, something to consider for PCB layout of ubitx or further development?
