Hello all
this cam in today on the SAREX mailing list, should be worth the effort to try and listen in.

This weekend (Jan 14-15 UTC) Bill McArthur plans to operate on the UHF band
exclusively. It is his desire to work all continents on the UHF band from
the International Space Station.
The frequency he will be using will be 437.55 simplex. Due to the high
Doppler effect on this band, one will need to operate split frequencies for
most of the pass. A very simplified chart showing memory assignment for
transmit and receive with 5 KHz spacing is below as an example .
Mem. TX - RX
Ch A - 437.540 - 437.560 Acquisition of signal (AOS)
Ch B - 437.545 - 437.555
Ch C - 437.550 - 437.550 Time of closest approach (TCA)
Ch D - 437.555 - 437.545
Ch E -437.560 - 437.540 Loss of signal (LOS)
Good Luck and 73,
