I had a PIJuice hat between the Draws Hat and the rPi 3b. showudrc.sh text showed that I was missing the UDRC radio. I placed the Draws Hat onto another rPi without the PIJuice hat, and the UDRC radio showed by rerunning the script.
I can confirm that using a PIJuice hat between the rPi and the Draws hat does not work. Something on the I2C bus must be interfering with the UDRC?
Next step: redo the SD card to a fresh rebuild and try loading the software again. Why? There are errors that must have occured during the initial setup on the missing UDRC were not captured.
