Yes, I'm probably getting confused. So, to reiterate: 1) Go to USB. Turn on 100hz calibrator. 2) Rotate dial so the tune is at 1000hz. 3) Adjust preselector for S9+25dB. 4) Rotate tuning dial to lower the tune and STOP at S9. 5) Adjust USB variable cap to shift the tune lower to 200hz. I know the calibrator is spot on. I was able to align it perfectly last night to WWV and it actually only needed a very slight nudge. It was off by maybe like 3hz.
