Flex 6300-wsjt-x ant 1 ant 2 problem

@raul3095 How or when it the antenna switching? Are you saying with no other programs in use, it will switch on its own? Are you changing bands?

I need some more info to understand your situation. Maybe a video?

ah, yes

So, if I remember correctly, that is working as designed but I can't remember the exact explanation. This also includes TX and RX antenna.

It comes down to how you change bands. When you change bands via the radio, the radio remembers the antenna from the last band (persistence). It is explained on page 68 of the SmartSDR manual.

Persistence, always enabled on your Signature Series radio, remembers settings from band to band without your direct action so that when you return to a band, your settings are restored. For example, if you are operating on 20m and set the Slice frequency to 14.185, then go to 10m and set the Slice frequency to 28.1 MHz and then go back to 20m, persistence will return your Slice to 14.185 MHz. Resetting the radio to the factory settings (see section 41) will clear the persistence settings.

So, the question is why. When you are doing computer generated band changes you don't want to yank antennas away from some other user/client and this is even more of a concern with Multi-Flex on SO2R operation.

What you see is the radio working as designed. It is a good question you had. I had to go ask a few people why it was done that way.
