Swan 350 can’t sync 80 meters frequencies and 20 meter frequencies per book and one L/C control VFO

Duh? And the problem was: I have used 700's and 500C and the 20m band is always on the GREEN band. ON this 350C the 20m band is jammed above the 80m band. I spent HOURS trying to figure out the mix with the IF frequencies. And I found due to the 5173 IF that the 20m band would start up the dial a bit.. And then I thought it would not match the green scale. And I looked at the dial again and DUH! There was the solution to the NON problem. ========== SWAN 350 has a COMMON oscillator for 80M and 20m in the VFO assy. For each band a rotary switch in the VFO selects the correct L/C coil. For 20 and 80m it is the SAME coil and variable capacitor. I got 80m adjusted perfectly. However. 20 meters is now about 175 Khz high. Not sure HOW this can happen. As there is only ONE adjustment for 20 and 80m If I make 20 meters work correctly then 80m is way off in calibration too.
