Re: K3s RX Ant port question

If you look at the diagram for the RX antenna (kxv3a/b) you will see that the RX antenna is switched out during transmit. if you have a Kadybook look at diagram figure 8-25. make sure you engage the rx antenna via the button next to the power button.

I would obtain  a DX Engineering Receiver Guard RF Limiter (DXE- RG5000HD.  Have used one for years in front of my receive antennas (Beverages,  HiZ 8, and SAL 30), and two of the three are close to my 160M phased verticals. 

And no, the RX port does not disconnect during transmit.

Does the rx ant port disconnect during transmit? Do I need to install a TR switch on the rx ant port to protect the K3? Running 1500w with tx & rx ant's in close proximity to each other. Don't want to smoke my K3S. 
I'm not finding a straight answer in the manual. I do have a automatic tuner installed. 
Thanks, Don KO7I

I  do have the sub receiver installed.
