Re: QCX-SSB: SSB with your QCX transceiver

Hi,

Yes, the lost receiver phase relationship for 80 and 60m is a known issue in R1.01d.
It has been fixed in a experimental version R1.01r here (yes, with plenty of new features): https://github.com/threeme3/QCX-SSB/blob/experimental/QCX-SSB.ino
You can use this version, or copy the si5351_freq() function into the old sketch.

The issue was caused by a pll frequency of 900Mhz, which is too high to reach a 90 degree phase difference for the lower bands.In the fixed version, the pll frequency has been lowered.
73, Guido
