So looking at the debug below.  Every time Radio 1 and 0 show, "send OFFCHAN req" they are going off channel per this bug?

Right, radio is going off-channel when message "send OFFCHAN req" appears.

 

I've seen this behavor on version 8.2, too. (FRA has been implementeted in 8.5)

 

When XOR radio is configured to serve 2,4 GHz only (manually), it goes off-channel to scan "country channels / dca channels / ..." for both bands.

So 5 GHz channels are scanned twice (radio 0 & 1).
