[ICOM] 756Pro Alinement, Shade Tree Mechanics

Frank, is calibration of the ref oscillator possible at home without special
tools?  Does the one ref oscillator affect all bands the same?

Am I correct in "assuming" this is not the freq calibration shown on page 76
of the 756Pro operators manual?

Thanks for any info and help
