I've been through the S meter calibration often enough that I can help question 1.
Turn the RF Gain to maximum. Turn AGC on Adjust R1 on the control board for a reading on U2 pin 5 of 3.8vdc. (It can actually be 3.6 to 3.8) Turn the AF Gain to any comfortable level. Turn on the XG1 and set to 50uv. Select CAL S HI from the menu. Adjust the VFO until the S meter indicates S-9 Turn off the XG1 and the S meter should drop to zero. Select CAL S LO from the menu. Adjust the VFO until the first bar on the S meter flickers, then back it off until the first bar is off. Turn the XG1 on and the meter should read S-9, turn it off and the S meter should drop to zero. Repeat the CAL adjustments as needed. I've discovered that if either CAL S HI or CAL S LO is severely out of range, that the calibration is difficult to achieve due to flickering. For this reason, it is important to adjust CAL S LO the first time even if the S meter indicated zero (it may be too far past zero) On Sun, 11 Sep 2005 20:44:04 -0000, <[EMAIL PROTECTED]> wrote: >Hi everyone, > >I've got a bunch of dumb questions so please have patients with me! > >1.
