Andrew Back andrew at carrierdetect.comHello, 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: http://people.osmocom.org/ipse/umtrx-v2/current/ But this doesn't seem to have made any difference. Is there anything else I can try? Cheers, Andrew -- Andrew Back http://carrierdetect.com
