Its hard to try to match up the number of segments lighted with any of the S unit marks. Thats the price we pay for not having a "real" analog S meter. I am thinking of calibrating the meter so S9 is nine segments lighted (50 uv) . One segment for each S unit. I would have to count segments instead of using the scale. I am not sure that the high end of the scale is important, anyhow. My Sierra dosen't waste segments on 40db over S9. I think that with a 40db over signal, the attenuator would be on or the RF gain reduced, either of which would change the meter reading. The bar graph has 10 segments so I could read to S10 (5db over S9 ?). I am not sure if the meter would be any less linear. 73 - Rick - K7MW From: "Stan Rife" <[EMAIL PROTECTED]> To: <elecraft@mailman.qth.net> Sent: Monday, February 21, 2005 5:10 PM Subject: [Elecraft] S-9 calibration with XG1
I just put the XG1 together and had a question about the setup on the K2 for setting the S-meter to S-9. In the K2 manual, the only mention of the XG1 is on page 48. This is the step right after the Cal SLo and Cal SHi functions. It does not indicate whether to have the preamp on or not. The instructions that come with the XG1 say to have the preamp on. Which is correct? I am assuming that it would be with the preamp on, since I get around S-5 with the preamp off, and close to S-9 with the preamp on. This is after doing the SLo and SHi calibrations. Also, what is considered S9 on the K2 meter? Just before the 9, or right under the 9 ? I am not trying to be too picky, just wondering what point everyone else is using, if there is a standard. Right under the 9 goes slightly past it and kind of looks like a better indication for a 5 over condition. Right now, the XG1 set for 50 microvolts lights the bar under the 9 on my S-meter.
