Vega-C: Inaugural launch Flight VV21(MEO orbit) - 2022-07-13 13:13 UTC

Did anyone else get an error in the flow graph files when loaded into Gnu_radio (windows versio, d/l from the S5lab website)? I had to add “int(…)” around the value for tx_sps in the Repeat Interpolation block (thank you to K4KDR for this info!).

I have not had any successful decodes or (as far as I can tell) digipeats this weekend. Is anyone using the gnuradio-rigctrl-software tnc-gui S5labs describes in their digipeater page? Are you using USB or FM downlink, and any frequency offset? My stock IC9700 + SatPC32 suggests 435310.555 (or close) as center freq, have tried on-center and offset 1600Hz. TIA, 73 de KS1G

Congratulations to K8DP for getting the first digipeat via GreenCube (1200 baud mode)!

And now we have the first complete contact via GreenCube - thanks to K8DP for being at the other end!

FYI, was surprised how easily I was heard by the satellite at that altitude using only 20w to a Wimo X-Quad (RHCP).

Here is the latest TLE set for GREENCUBE calculated by @PE0SAT:

GREENCUBE
1 53106U          23032.60000000  .00000000  00000-0  00000-0 0    04

EDIT: Due to a typo I did, the initial TLE set was calculated for the wrong epoch. I’ve updated the above TLE set with the right epoch.
