Re: What happened to Greencube IO-117?
Thank you Doug for making me aware for the possible scenario which may happen at my end. I will try with not so busy pass in beginning as you suggested. Btw my setup is 100% portable, I shall be operating from my rooftop or field, so need some time to be comfortable with it. Also I will schedule my activity, not all passes will be possible for me to work! Re. chasing your grid EN62VT with IO-117 we do get small window with pass of approx 5° or so. Will try our luck very soon. Thank you 73 Rajesh Vagadia VU2EXP Rajkot Gujarat India ML52JH

Hello Rajesh,
It was good to see your message about being QRV Greencube on the AMSAT-bb. To date, only VU stations from the south have been active on IO-117, because of this only a very limited number of NA stations have been able to complete a QSO with VU! I am located in Michigan EN62VT; I believe we will have a short window of opportunity to complete a QSO and I certainly look forward to that opportunity!
Greencube has been offline for some time, but has now been active since the 08Z pass between JA and NA this morning. It is hard to say if it will remain operational or if it will go offline again, so keep an eye on the AMSAT OSCAR status page...
You should be able to get in with 10W and 14 elements, however once you get one packet through you might not be able to break the pileup that will result. Keep in mind that this is a single channel simplex bird, so not every packet you send will be digipeated due to collisions. Timing your transmissions will improve success! Try experimenting when the footprint does not include EU or NA; this should give you a little breathing space to get everything sorted out.
I hope to hear you on IO-117 soon!

Thank you Bill for pointing out on Greencube current status! Yeah now amsat status page also reflects the QRV reports from users. I am getting prepared to work this beautiful bird with my 14ele yagi & IC-705 in portable fashion. I still want to know how many members are successfully working IO-117 with Icom IC-705 (10W)? Thank you 73 Rajesh Vagadia VU2EXP Rajkot Gujarat India ML52JH

Rajesh,
IO-117 has been not working for several days. It was back on this morning.

Dear all, Few months back I was trying to work Greencube Satellite with my limited setup, I was able to receive signal packets & telemetry with my 7 ele uhf Arrow antenna, though I could never Transmit & successfully trigger this Bird, perhaps my IC-705 limited 10W power was the issue. Now I am equipped with a new High gain cross yagi (14ele) to test & try Greencube! I observed since more than a week Greencube is not QRV! Can anyone give idea what happened to this beautiful bird? I am quite eager to work via this satellite from my grid ML52JH. I would also like to get response/guidance from user with Icom IC-705 who worked this bird successfully.
