[Elecraft] Is the antenna tuner needed on the KX2 to see SWR?

[Tyler Haske]

I'm building my first HF rig and I've opted to go without an antenna tuner
since I plan on using a magnetic loop.

I see in the loops instructions I need to know the SWR to tune the antenna.

I see in the KX2 instructions it has overload protection based on the SWR.

... does the KX2 know the SWR without the tuner?
