Artist's impression of RS-39 |
RS-39 heard
On the AMSAT bulletin board Jakub Hruska reported receiving signals from RS-39 shortly after deployment.
Chibis was heard during short pass (6deg max EL) over central Europe.
Both frequencies (435.315 and 435.215 MHz) seems to be active, with lower one modulated with some data/voice and upper one first just CW
beacon, then switched to modulated as well.

Signals were really weak, but next pass should be better.
Times of signal AOS/LOS fit the PROGRESS-M 13M keps.
For the next pass he reported:
CW telemetry on 435.315MHz:
RS3? UB??16 IBS122 UIUN22 ISUN0 ITXA0 ITXB0 TTXA136 TTXB134 TNAP133
TAB137 MSEP0 MCON5 SMA100 SMB99 MRXA2 MRX?F
RS39 UBI1W4 IBS80 ASUEEW ISUD0 ITXA0 ITXB0 TTXA135 TTXB136 TNAP13X
?XB237 MSEP0 MCON5 SMAJ?3 SMB94 MRXA2 MRXB2
RS39 UBS132 IBS59 USUN?8
RS39 UM??W2 IBS59 USUN21
On 435.215MHz, some data (PM carrier with sidebands, my guess is 1200Bd manchester coded).
In India Nitin VU3TYG reported:
Heard the RS-39 CW telemetry during the 4:14 UTC pass over India.
Recording can be found at http://www.vu3tyg.addr.com/RS-39/ .
Thesignals were strong and I was following the keps of the Progress
M13 M cargo ship. The RS -39 CW signals were heard 2 minutes after Progress M13 in range.
