[amsat-bb] Delfi-C3 over West Malaysia

Tue Apr 29 18:49:11 PDT 2008

Dear All,

Finally managed to copy Delfi-C3 during a 9 degree elevation pass this
morning, 0922 local or 0122 UTC over West Malaysia.  Unfortunately, I failed
to log into the Delfi server for some reasons - have to check my login
again.  Also briefly heard SEEDS again on this pass, while Cute-1.7 + APDII
was not heard.  Is Cute-1.7+APDII continuously transmitting CW telemetry on
437.275 MHz?

Captured telemetry are as below.  A screenshot of RASCAL is available at

Tuning the downlink for Doppler is indeed not a simple process but luckily
still manageable.  Have another pass at 1055 local or 0255 UTC where I will
attempt to copy again.  Both SEEDS and Delfi-C3 were copied using Object C
keps.  Equipment used, IC-910H, 2x10 Yagi for VHF, 2x15 Yagi for UHF,
SB-2000 VHF Preamp and SB-7000 UHF Preamp.  All horizontally polarized.  

WAV or MP3 recording of Delfi-C3 also available on request.
