umtrx_vcxo.py always reporting 2048.

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
