It's possible that we're dealing with a memory leak somewhere.
Could you watch the memory consumption of simple_ra over time?
Also, could you just run something like uhd_fft with the same
sample rate for long periods to see if it gets the same 'D'
treatment?

Ok, Marcus, will do. Overnight (NZ time) I got 1 D with the Atheros.
I should have said that the N200 was in the shack and the Ubuntu
system in the house. I have several runs of Ethernet out to the
shack so will do some experimentation on the different connections.
Then I will move the Ubuntu system to the shack and see if
colocation helps. These investigations will take some days but will
let you know.
