Hans,

I have been having a similar issues on 20m. (20M to 10M QMX). When first running calibration, I used "R" run mode to do everything via the console.? On both 20m and 11m the Phase Error vs DAC plots finished very quickly and looked strange.? SSB effectively did not work and was just distortion on Tx.?? I re-ran BOTH Phase and USB for 20m using "O" once mode and while the Phase plot still looks strange it did change. Tx improved and I have been making contacts.?? The Phase plot changed when I ran it in "O" mode.?

Adam,? I had a similar wierd short plot on 20m (see earlier post on earlier beta thread with audio clips) which resulted in distorted transmit audio on 20m only (the other bands were good).? I found that going into the band configuration and changing the 20m centre frequency small amounts drastically changed the plot.? I settled on a 20m centre frequency of 14300000 which produced a smooth descending plot although not with as many points as say, 17m.
