Is it normal for the scale to vary a couple Kc's band to band? For example, If the Calibrator is dead on 7.500 on the 7 Mcs band, is it normal for it to be maybe on 8.502 on the 8 Mhz band and maybe 9.497 on the 9 Mhz Band? I do not see any trimmers to bring each crystal dead on. Am I missing something? Thanks, Gordon N6WK
