Nick, Yes, you set CAL S Lo with the antenna removed.
The order of adjustment is: 1) AGC Threshold, 2) CAL S-LO, 3) CAL S HI. You may have to cycle through 2 and 3 a couple times, there is a small amount of interaction. When setting CAL S HI, first set it for full scale deflection, and then check the S-9 level with the XG1 - if the meter reads a bit below S-9, you can increase it with CAL S HI, but if it is higher than S-9, go back and change the AGC Threshold by a small amount (I suggest 0.2 volts at a time) and re-do CAL S LO and CAL S HI again. Repeat the process until you have the S-meter deflection that you want. If you use CAL S HI alone to REDUCE the reading with a 50 uV input the result will be a lack of full S-meter deflection. I know that is a bit more involved than the instructions in the manual, but such are the problems involved in 'fine-tuning' several parameters - they interact. Once you have adjusted everything with no antenna and the XG1, if you see S-9 when you connect the antenna, then you may conclude that you have an S-9 noise level! 73, Don W3FPR > -----Original Message----- > > S-meter alignment...
