UHF weekend on the ISS

This weekend – 14. and on January 15, a direct connection with Bill McArthur on board the ISS will be possible exclusively on the UHF band. It plans to enable QSOs from stations on all continents.

There will be a frequency worker 437,55 MHz. Due to the Doppler effect, at least one station must co-frequency shift during the flyby. For owners of stations with 5kHz rasterization, it is recommended to pre-program the frequencies into the memories as follows:
Mem. TX – RX
Ch A – 437.540 – 437.560 Acquisition of signal (TO THE)
DISCLAIMER – 437.545 – 437.555
Old age – 437.550 – 437.550 Time of closest approach (TCA)
Ch D – 437.555 – 437.545
Ch E -437.560 – 437.540 Loss of signal (THE)
