Excellent AO-92 decoding, 10 degree pass. Switching LHCP/RHCP in middle did help a lot.

19 nya medlemmar under 2019
During 2019 AMSAT-SM has a number of 19 new registred users/members. The total number of members are now 267.
AMSAT-SM kan glädjas åt att fått 19 nya medlemmar under året. Jag blev faktiskt lite överraskad när jag räknade ihop det…
Vi har just nu 267 registrerade medlemmar, med vetskapen om att en stor del av dessa är passiva och kanske inte ens vet om att de är medlemmar, då en del blev överförda från det gamla medlemsregistret.

XW-2F Activity 2019-12-21
Try to listen to one specific satellite per day during X-mas. Today XW-2F.
CAS-6 – en lite större satellit på 60 kg som har amatörradio ombord. Vi hoppas den blir en fin satellit med många FM-kontakter. Från AMSAT-UK:
CAMST’s amateur radio payload CAS-6 piggybacked on a technology test satellite TIANQIN-1 launched at 03:21 UTC on December 20, 2019 at the Taiyuan Satellite Launch Center of China using a CZ-4B launch vehicle.
Update December 20: Alan BA1DU reported:
“Today CAS-6 has been successfully launched, the satellite is currently in orbit testing, the amateur radio payload is expected to be operational in about three days. Thank you for your interest.”
The primary payload of this launch is China-Brazil Earth Resources Satellite CBERS-4A.
