Thanks, Nicola. I found the preferences setting and turned off the parameter display. It had been on and saved that way in my show file. The change has now been saved to my baseline show file so I won’t have the display annoyance any more.
You addressed my other question, in the last response to Mike. The jitter I saw was on the order of only +/- 0.2 dB. Much too small to be concerned about (??), but enough of a change to trigger the display. Is this level of jitter considered normal, or is it enough to justify contacting your local distributor?
