[Elecraft] Trying RF Gain Calibration with XG3 but fails

[Randy Diddel]

Hi David,

I will try a different USB cable although I am using the brand new one that came from Elecraft with the XG3 which arrived a few days ago. I will check the k3 Utility version.

Thanks for the response!

If this doesn’t help, I would suspect that your usb/serial link between your Mac and the K3s may have become marginal resulting in lost data while sending those rather large dsp commands to the K3s. The solution may be as simple as trying a different usb cable.

I even tried reloading the firmware on the K3s just to see if that worked. Of course turning it off and back on again did nothing either.  I DO have the SUB RX on this rig as well, ideas?
