AO-40 MB frequency



AO-40 (2401.323MHz) on 3 June 2002
UTC        IF         Observed    Shifted     Predicted   Differed
03:09:00   145.3635   2401.3635   2401.3645   2401.3577   +6.8
03:10:00   145.3637   2401.3637   2401.3647   2401.3579   +6.8
03:11:00   145.3639   2401.3639   2401.3649   2401.3581   +6.8
03:12:00   145.3641   2401.3641   2401.3651   2401.3582   +6.9
03:13:00   145.3643   2401.3643   2401.3653   2401.3584   +6.9

UO-11 (2401.500MHz) on 3 June 2002
UTC        IF         Observed    Shifted     Predicted   Differed
04:49:00   145.5507   2401.5507   2401.5517   2401.5500   +1.7
04:50:00   145.5479   2401.5479   2401.5489   2401.5472   +1.7
04:51:00   145.5432   2401.5432   2401.5442   2401.5425   +1.7
04:58:00   145.4549   2401.4549   2401.4559   2401.4532   +2.7
04:59:00   145.4519   2401.4519   2401.4529   2401.4502   +2.7
05:00:00   145.4502   2401.4502   2401.4512   2401.4485   +2.7

where,  Shifted  = Observed + Audio_frequency(ie, 1kHz USB)
        Differed = Shifted  - Predicted_frequency

and I calculated these predicted frequencies by using Calsat32
for JPN use.

Consequently It seems like the MB frequency from AO-40 is about
2401.327 MHz.
