Sounds like someone peaked up the tuner at the top end of the band only. It's a split the difference kinda deal going from low end of FM band to high, back and forth making adjustments. Shouldn't be all that difficult for a tech experienced with tuners to align it properly with a good signal generator and service manual.Just got my SX-1980 back from repair.It's pumping the woofers and sounding great.The only problem is the tuning isn't up to par as it should be.It doesn't pull in stations from 88 to 100 but does fair from 100 to 108.The tuning and signal meters are erratic on the left side....I realize that it's very time consuming and hard to adjust the tuner and capacitor just right.The APC could not be adjusted good enough to get the fine tune and quartz light to come on.
