I tweaked L34 (which was set properly) and tried peaking L1 and L2, which were also set properly. I'm wondering if I'm missing something simple before I begin to check some other items. The receiver appears to work properly in all other respects and to be truthful, I hadn't noticed it being a bit weak, but upon comparing it with an A/B switch, it lacks some sensitivity. Thanks in advance for any pointers. ----------------------------------------- You can't get an idea of the absolute sensitivity of your K2 looking at the S-meter, Mike. You can adjust the S-meter to indicate anything you want from any signal you want. A blockbuster signal can be S1, our you can adjust it to make a signal down in the noise S9! Look up "Receiver Sensitivity Testing" (Page 4 of the XG1 manual) and "Signal-to-Noise and MDS Calculations (page 5) for instructions on how to use the XG1 to measure receiver sensitivity. If you don't have the manual, you can download it from www.elecraft.com That procedure will allow you to determine the signal-to-noise ratio and the minimum discernable signal (MDS) of your K2. You can use the same procedure to evaluate other receivers for comparison.
