[Elecraft] K3: RF gain settings forgotten in utility cal routine when using XG-2

[N. Munro]

I'm also having problems doing an RF Gain Cal using the latest K3 
Utility (and a few other recent versions).
Various error codes are displayed and the Rx sensitivity is well down 
after I cycle the Power switch off and back on again. The S meter only 
reads about S5 and the MDS drops from -136 dBm to about -120 dBm. Like 
you, restoring the Factory Default settings gets me back to normal.

I have gone back to K3 Utility Ver 1.2.8.10 and everything works as it 
should. The matter has been referred to Gary Surrency at Elecraft 
support and I would expect a reply tomorrow. For info, I have completely 
disconnected the P3 and the RS232 cable from the PC is run straight into 
the K3.

-----------------------------------

/All of a sudden, I'm having trouble with the K3's receiver following RF gain
calibration and S meter setting.  The RF gain calibration using the utility
leaves the receiver with S9 at -73dBm (using ZG-2) but when I turn off and
then on the K3 the S meter drops to S7 and the RF gain control, although
reducing the perceived signal strength, does not cause the S meter to rise.

The agc has completely default settings throughout.  For the purposes of the
calibration, the K3 is directly connected to the PC, not through the P3.
I'm running the latest firmware and K3 utility.

Having taken a break from typing this, I have only now just found that if I
choose to 'Use factory default RF Gain calibration data' then all is well,
so is this a bug within the latest utility I wonder?

Thanks
