Re: KD8CEC 1.072 download
Ian... would you PLEASE consider writing the version number in the file name of the code? That way different versions can be saved easily in the Arduino ISD. Dr. William J. Schmidt - K9HZ J68HZ

Apology
I wish to apologize for my statements on the list last night. I'm not going to make excuses. I shouldn't have said what I said and I know it. I'm likely to ask some stupid questions as I go along

Re: Teensy 3.5/3.6 upgrade for uBITX
I said almost the same thing a day or two ago...it has some really nice features, like a 12-bit ADC (4096 instead of 1024). Another important plus is that it can be programmed and run in the Arduino

Re: Teensy 3.5/3.6 upgrade for uBITX
I see the complexity and cost growing exponentially. That's fine but I really don't see the uBIT-X as suited for going in that direction.?? It depends.? If you can fabricate a transceiver that

Re: Teensy 3.5/3.6 upgrade for uBITX
To continue a little further.....I see those who are interested in DSP and other number crunching applications will require a RPi, Teensy 3.5/3.6, or STM32F4xx/STM32F7xxx microcontrollers for

Re: Teensy 3.5/3.6 upgrade for uBITX
In keeping in line with Farhan's $100 goal for the Transceiver, I would seriously look at using the "Protoneer" mentioned by some others. It has the "Nano" form factor, is Arduino Zero based, runs at

Re: Teensy 3.5/3.6 upgrade for uBITX
I'd bet worst case latency on a not seriously loaded RPi is less than the milliseconds it takes us to load a new clock frequency into the si5351 via 100khz i2c. A google for "Rasberry Pi RT" shows
