    @loglow - Dan - I hope I'm wrong but I suspect there's a mismatch in the order of the traces on the flex-cable and the pcb trace to pin 36 at the flex cable socket :( This morning I got the replacement T4...

    Well, I remembered that I'd seen T4's at the local electronics store (You-Do-It Electronics in Needham, MA), so I jumped in the car and got the last one! So back in business tomorrow morning. A few more comments on...

    @loglow Dan, I've assembled the new board - thanks very much for including me. It went very well, much smoother than the first Beta - took about 3.5 hours with quite a bit of time spent working out a sensible...

    As promised, I'm back ;) .... @robjohn - To answer your questions: 1) No, I'm not using the Weaver SSB method here. Although I am very fond of it, I had too many problems with the Weaver method and the Teensy Audio...

    @xerox, I guess you are working on a ham radio project - SWR/power meter? That's very interesting, I just started thinking about a Teensy 4 antenna-analyzer/auto-tuner/SWR meter myself, for after I finish my current...

    @loglow --- Hey Dan, For health reasons I've had to take a break from things Teensy over the past few weeks, and things got away from me. I am finally catching up and am delighted to see the progress you've made. ...

    Yesterday I received two packages in the mail, (a) more T4s to destroy, and (b) samples of FRDM4236's board. So I got to work and assembled two of my slightly modified (stretched) versions of Blackketter's board, and...
