[Elecraft] Problem on the first weekend...

[Bill Blomgren (kk4qdz)]

I'm not sure which part of what I did managed to make the machine confused enough to lose the bias setting...
 
Had I known ahead of time that the error indicated that I would have just run that calibration .. but did whatever caused that problem step on other calibration  data?

KK4QDZ - Now with Extra Class Priv's, and a tiny KX3 to enjoy them!

Also the KX3 has to be powered by a power supply and not the internal batteries for the TX Gain to calibrate.

Glad you're making headway.

I had no problems with kit number 21.

The book said set it to 4 watts (exactly) - so I did that.
