Arv,
Here is a link to a company that produces the hardware and software to replace the v6 Raduino with one that is designed for the Teensy 4.1.?
They sold an adapter board for the pre v6 Raduino, however that has been discontinued. ??
The cost seems reasonable, considering it is not in high demand and the low volume of boards sold (assumed). ?A good choice for someone who wants to experiment with things like DSP or other SW based additions to the uBITX. ?The supplied code is open source and can be worked with the Arduino IDE.
