Diversity antenna selection oddity

[Brett Howard]

Am I imagining things or did selecting diversity previously
automatically put the to receivers on different antennas.

The other day I was trying to do some testing to measure filters in
each receiver so I was using Diversity to try and get things onto the
same frequency and so that I could do measurements on both RXs on the
same freq...

Anyway I was having a hard time seeing things on the second RX...
Until I realized I was doing diversity with both receivers on the same
antenna.  I could have swore that previously when both RXs were on the
same antenna that a long hold of SUB would put me in diversity with
two different antennas and then when I exited diversity that it would
go back to the way I had things...  Am I remembering wrong and mixing
dreams with reality or did something recently change?

Brett,

A long hold of SUB puts the second RX in diversity mode, but it does not
affect the antenna selection. Holding the RX ANT button toggles the
second RX between the transmit antenna (called MAIN) and the second
antenna (AUX).

I could have swore it changed it for you before...  Can anyone think of
a time that one would want the two receivers PLL locked and listening to
the same antenna?  

This makes me wonder if I've ever missed that and thought I was doing
diversity but instead I was using two receivers to listen to the same
antenna.

Perhaps this could be an enhancement to go in and out of this...  That
is of course unless there is a reason that I'm missing why one would
want to be in diversity mode yet still have both receivers on the same
antenna port.  Seems like if that was something one would want to do
they could use LINK and then hit A>B twice.  But in diversity it seems
like that should always be used on two antenna inputs.

Thoughts?
