Thank you Kent and also thanks to Tom N5GE and Ken K3IU for their replies. Downloaded the latest utility but still got the error message on doing the RF gain calibration on the sub rx.

Good! I've been mostly up on the beta changes and done some alpha testing. But in there I've gotten out of sync or some silly thing four or five times and needed rescuing.

Re: [Elecraft] K3 RF Gain calibration
OK, here is the heads up. Mea Culpa (as usual :) ) What I had done before was to use CWT and spot to zero beat the signal from my XG1 and then switch off CWT. I now assumed the signal was centred. This does not appear to be the case. I tested this with all 3 versions of the Utility and got the same result. Then I did it manually, centering the signal by ear et voila! It now looks and feels right :) 73 Ian -- Ian J Maude, G0VGS SysOp GB7MBC HB9DRV-9 DX Clusters Member RSGB, GQRP 9838, FISTS 14077 | K3 #455 http://www.amateurradiotraining.org On 24 April 2010 15:38, Joe Planisky jp...@jeffnet.org wrote: Hi Ian, Some earlier versions of the K3 Utility for Mac and Linux would produce the symptoms you describe.

Re: [Elecraft] K3 RF Gain calibration
Run the calibration step again. I had to do it 3 times before it would behave itself. My symptoms were somewhat similar to yours. Be very careful to follow the instructions exactly and especially make sure you have the test signal centered in the very narrow passband specified. After the 3rd attempt my S-meter is perfect and whan backing off the RF gain it rises smoothly up to past the S9+60dB point. AB2TC - Knut Ian Maude wrote: Yes I did Ken.

Re: [Elecraft] [K3] RF gain calibration and S meter
I agree. Something is not right here. I just tried the RF gain calibration (3 times) with the Mac K3 Utility. I followed the instructions presented by the program to the letter. I then proceeded to do the S-meter calibration as specified in the manual. Immediately after RF gain and S-meter calibration, everything seemed fine. Sensitivity seemed normal, s-meter responded to signals as expected, turning RF gain full CCW resulted in an s- meter reading of S9+50. After turning the rig off and back on, however, things are about like W7TEA reports: sensitivity seems reduced, turning the RF gain fully CCW gives an S-meter reading of S3, and a 50uV signal now gives an S5 reading (with preamp on.) I borrowed a Windows computer and repeated the exercise. This time, all was well even after a power cycle. It seems like the problem is with the Mac version of the K3 Utility. 73 -- Joe KB8AP On Oct 31, 2009, at 9:48 AM, W7TEA wrote: Just ran the RF gain calibration with the new Mac K3 Utility and an XG2.

Re: [Elecraft] [K3] RF gain calibration and S meter
Hi, Go back and redo the calibration! Make sure to follow the instructions exactly and pay special attention to ensure you have test signal centered in the passband. This is critical since the instructions call for a 100Hz bandwidth. I had similar symptoms as you until I did this the 3rd time. 3 times makes perfect and my S-meter is not dead on at 1uV, S9 and S9+40, the three easy cal points I have. Backing off the RF gain, S-meter rises smoothly to S9+60 and the radio gets deadly quiet. AB2TC - Knut W7TEA wrote: Just ran the RF gain calibration with the new Mac K3 Utility and an XG2.
