Hello,
I'm attempting to perform TCXO DAC calibration. However, whenever I run umtrx_vcxo.py it reports the current DAC value to be 2048, regardless of whether the GPS antenna is unplugged, or it is plugged in and GPS has a lock.
I've updated the FPGA and ZPU firmware with those found at:

But this doesn't seem to have made any difference.
Is there anything else I can try?
Cheers,
Andrew
