[Elecraft] Sub RX audio in diversity changes when BSET is active

[K2MK]

I'll throw this out for comment. I don't want to say it is an error since it 
may be per design.

We know that in diversity the sub RX is tuned to the VFO A freq and VFO B 
can be set to another frequency. When I press the BSET button, the audio 
from the sub receiver changes from VFO A to VFO B.  It's very evident with 
headphones. Audio from VFO A is still present in the left ear and the right 
ear now has audio from VFO B. (VFO B can also be retuned at this time). When 
I turn BSET off the right ear audio goes back to the VFO A diversity 
reception.

I found this useful when using diversity and split at the same time. I had 
tried diversity and split before using the REV button but was not able to 
tune VFO B using that method. So maybe this is an undocumented feature.
