AO-40 K passband is Strange modulation.

orbit #1012 (01/13/03) and #1016(01/16/03)

AO-40 K band passband downlink signal was strange modulation.
I and JI5MFZ , JH1PEF experienced the AO-40 K passband downlink signal
expect late MA=131.
I uplinked USB both 70cm and 23cm then I received normal USB downlink on S2.
But K band downlink signal was undemodulate voice, not a USB or LSB.
Late MA 131 was normal when LSB uplink then USB clear K band downlink.

JA Ready for K band now
