On April 4, AMSAT-DL announced the opening of the QO-100 NB satellite transponder to general contest
operation in the upper mixed-mode range. This weekend (April 10-11) will see the Yuri Gagarin contest.
The contest area on the QO-100 geostationary satellite NB transponder for both CW and SSB is:
Uplink area 2400.370 – 2400.490 MHz
Downlink area 10489.870 – 10489.990 MHz
Of course, the usual QO-100 NB transponder guidelines also apply here. Therefore, the bandwidth should still be limited to 2.7 kHz and the transmitting power should be reduced to the necessary level, i.e. only as much power as necessary should be used.
