Mike, First make sure you have the RF Gain set fully clockwise, and then adjust the AGC Threshold to 3.8 volts or a little lower (never higher). The adjust CAL S-LO with no antenna connected just to the point where there are no bars illuminated in any mode. Now, if you have a source of 50 uV RF (-73dBm) like the Elecraft XG1, XG2, or XG3, tune in that signal and adjust CAL S HI to indicate S-9. If you do not have such a signal generator, you can adjust it "like the book" and turn the RF Gain to minimum and adjust CAL S HI to illuminate all 10 bars (or the 10th bar if you have graph in dot mode) and let it go at that. Alternately, if you have a steady on-the-air signal that you believe should register S-9, adjust CAL S HI until that signal does read S-9.
The K2 (and K3) S-meter can be calibrated to the S-9 equals -73 dBm "standard", but for a long time, many receiver and transceiver manufacturers designed their S-meters to get a LOT of "needle swing", so if you are comparing with other transceivers that you are accustomed to, you will find the K2 s-meter "stingy". As I indicated, you can "perk it up" by setting CAL S HI to a lower number. 73, Don W3FPR On 7/30/2011 11:55 AM, vicki glover wrote: > GM OM, > I have gone through the S meter Zero and Sensitivity a couple of times and am > sure I'm doing it BTB, but indications of incoming signals seem low to me. > Signals that I think should be a least a 7 or even a 9 are indicated as a 2 > or 3?
