Lack of Diversity setting persistence on 40m

Thank you for your response. I re-read the manual sections on profiles. I am using the SO2RDefault Global Profile and three TX Profiles: 80M CW, 20M - 40M CW and 10M - 17M CW which are basically the same, but 10M - 17M CW has 8db gain added. All are set for CW 400 NB NR APF QSK AGC-M DIV. The MIC profile associated w SO2RDefault is Default.

This is my default operating configuration, one Panafall, one Slice. Sometimes I'll turn on SL B to work a DX station split, but then I'll put it back to default.

The Maestro manual section 14.7 implies that Persistence and Profiles are independent, although I can imagine that there might be some undocumented Persistence dependence upon the state or configuration of one's profiles, so I double-checked mine.

I move back and forth between 80, 40, 30 & 20 and have the SO2RDefault : 20M-40M CW : Default Mic profiles engaged. Here's is what I observe happens WRT persistence in order of frequency:

1) DIV is turned off after moving to a new band
2) If DIV is not turned off, often Tab A is panned R (so both Tab A and Tab A Div on on the R ear)
3) DIV off as well as NB, NR, APF all off, but the sliders for NB, NR & APF are remembered
4) SL B is activated and comes up on 14.150 USB 2.7k, this happens on any SL A band
5) SL B appears 14.150 USB 2.7k in a second Panafall

I've also noted that my RX equalizations have been zeroed, although I don't know when.
All the dial-associated settings seem to persist (e.g. AGC-T, filter mode & settings, everything on the TX menu.)

BTW, I had a separate thread on the ATU / QSK conflict and I am favoring using the ATU in preference to QSK. However I am note that the QSK does not always vanish, sometimes I can have both.

This is just an annoyance for me, half a dozen button pushes after band switching and I'm back in business. I'm not a contester. More importantly, I'd like to know if others observe this same behavior or whether there is something wrong with my brand new Maestro / 6600 or my configuration of them?

On this last point, I have also heard Radio-originated popping in the headphones periodically and have assumed that was a software implementation artifact to be ignored. Do others hear these?

Configuration-wise my 6600, Maestro & Macbook Pro all have short EN cables to a gigabit switch which has a 30' EN cable to the router. I am on the second floor. A 1ft #10 copper ground wire connects the power supply to the 6600 and a 15ft #10 copper ground wire to the mast of my vertical which has a 12ft ¾" strap to earth ground. Not ideal. I will be installing  common mode chokes on all lines this weekend. Currently only ANT1, the HWEF-8010, has a CM choke which dropped the noise floor 4db.

Thanks in advance for insights,
