[Elecraft] How to get SWR

[w4sc]

Holger,

Glad you solved the problem.

For “TUNE” hold, I have my KX2 is set to a fixed level (3 Watts) by the TUN PWR menu entry.  So the power level issue was masked in my setup.  I don’t know what minimum power level is required for an accurate SWR reading, and ATU tuning.  The designers may want to comment.  For KX3 ref pg 14 in owners reference.

The KX3 may be “fast enough” to not need a delay in your code.  The KX2 appears to not be.
