[Elecraft] Possible firmware bug - Diversity receive

[Adi Andrei]

Hi,

I think there might be a minor bug in the K3 firmware when switching antennas in Diversity mode.

Context:

Have 2 antennas, connected to Main and Aux, that even on the same frequency give you signals which are different enough that you can tell the difference.
In normal (non-diversity mode) make sure you have both receiver and sub-receiver antennas set to Main.
Switch to diversity mode.
Click B-Select
Set sub-receiver antenna to Aux.
Click B-Select

..so far so good, we are in diversity mode, subreceiver set to go with Aux antenna.

Now, suppose I want to change the NR settings on Subreceiver.

Click B-Select

ooops, I can't hear what I used to hear through the Aux antenna, for some reason the sub-receiver is now connected to the Main antenna (the non-diversity setting for the antenna).

Click B-Select

the Sub is again on Aux antenna, and everything is normal

Click B-Select

the sub is again on Main antenna

This behavior will not happen if the Sub was set to Aux antenna BEFORE going into Diversity mode.
So is this normal ? Or it is a bug that was not spotted before because usually the signals between the two antennas do not vary strongly enough to be noticed, and/or people set their Sub antenna before going into diversity mode.

I think intuitive operation mode would be to either have just one antenna setting for subreceiver regardless of being in diversity mode,
or, have the different settings, but then when in diversity mode, make sure the sub stays connected to the Diversity setting.

Thank you,

Adi
