Bill, oh now I see what you mean. I am such a dope.  I thought just checking Rx only was enough...of course I have to tell it WHEN to Rx only.  Clearly I need more coffee. hahah.
 
I added night for 160, and day for 30/12 all with RX only.

Thanks much for helping me figure this out. 

And thanks for the note that spending more time on 80/40/20 and less on the high bands might not be a good tradeoff. But I should test that at some point....hum....thanks again.
