[Elecraft] KX3 - SWR Display of "--"

[stan levandowski]

  I just got a KXPA100 yesterday.  It seems to work as specified except 
that above 10 watts of power, the KX3 display randomly {like in "not all 
the time"} shows two dashes instead of the SWR. 

I do not have the internal tuner option.  I am using my SGC237 
autocoupler into a center fed Zepp.  My W2 wattmeter shows the proper 
power output and the SWR  is usually 1:1 or very close.

This does not occur at power levels at or below 10 watts which means 
it's most likely not the KX3's problem but rather the amplifier's 
behavior.

Happens on different bands and frequencies.  If this is documented 
somewhere then I've missed it.
