Re: [Elecraft] K2 S-meter adjustment
Chris, The CAL S LO and CAL S HI values are as you observed. Turn the RF Gain to full clockwise, and remove the antenna. Turn the preamp on. Adjust CAL S LO first so there are no bargraph LEDs illuminated. Then tune in an S-9 signal (preamp on or off, your choice), and adjust cal S HI for an S-9 indication in the bargraph. Usually that value will be between 23 and 19. 73, Don W3FPR On 8/27/2018 2:13 PM, Chris Kimball wrote: Thanks to Martin and Don. Yep, the age setting had mysteriously advanced while in storage.

Thanks to Martin and Don. Yep, the age setting had mysteriously advanced while in storage. I had forgotten about the CAL submenu. Messing with the settings got me some more reasonable S-meter action. Apparently the S LO should be greater than S HI in normal operation.

Re: [Elecraft] K2 S-meter adjustment
Chris, On older K2s, there is no adjustment for AGC Threshold kike is found with the newer ones which have a pot to set the AGC Threshold. R1 on the control board - which is normally adjusted to produce 3.8 volts at CB U2 pin 5. You can always set the CAL S LO menu parameter and CAL S HI to produce no bars with no signal and an S-9 indication with an S9 signal. The latter is normally set with the preamp turned on, but preamp off can also be used. We are in a sunspot low, so signals may not be as strong right now, particularly on the bands above 30 meters. 73, Don W3FPR On 8/27/2018 12:38 PM, Chris Kimball wrote: Just took out the old K2 from storage and it works great, perhaps better than my memory of how to us it! Seems like the S-meter is insensitive. With the Preamp on the meter works as expected, but otherwise no indication at all, even for signals with very good S/N. Is there an adjustment or parameter change to make the S-meter more sensitive?

Re: [Elecraft] K2 S-meter adjustment
Did you check the S meter calibration in the menu? It could also be the age setting has moved a bit, I find mine is quite sensitive to that.
