[Elecraft] Tune Button with ATU off

[Walter Underwood]

Yes, that is the purpose of the TUNE button.

"One measure of how close an antenna is to resonance is its SWR (standing wave ratio). The KX3 displays SWR in TUNE mode (pg. 14). “    KX3 manual, page 6

"TUNE is used to put out a CW signal at the power level selected by the PWR control. This is useful with external wattmeters and antenna tuners. If the TUN PWR menu entry is set to a numeric value, rather than NOR, then this value—if lower—overrides the power control setting.”  KX3 manual, page 14
