FO-98 OrigamiSat-1 5.84 GHz downlink
I apologize for the short notice.....
The OrigamiSat-1 Team will remotely activate the 5.84 GHz downlink on FO-98 for four upcoming passes over the Northeastern US. The times listed are based on my QTH here in Vermont at FN34jm.

I manually updated my nasa.all file in SatPC32 to use these.

If you have 5.8 GHz receive capability and are in the Eastern US, please consider trying to detect the downlink.
The equipment I am using is the same that I used to successfully detect NIWAKA in 2012 on 5.84 GHz.
DEMI 5.760 GHz transverter with a 2' dish and Directive Systems linear feed (Horizontal). I also have a DEMI preamp inline. The IF I'll be using is a Funcube Dongle Pro+ set for 224 MHz. This equipment is my terrestrial 5.760 GHz system which works quite well out of band at 5.84 GHz.
Please report any success here and you can also use the reception report on their website. The OrigamiSat-1 team is also on Twitter. @OrigamiSat1
Dear Mike,
We, OrigamiSat-1/FO-98 team, are very sorry to inform you that we have just failed to uplink the command to the satellite for the 1st trial:
31.05.2019 FO-98 01:29 01:39 10 59 157 - 351
because of the server error in our ground station.
We will try again for the next window, a half day later.
31.05.2019 FO-98 14:30 14:40 10 59 015 - 188
We deeply appreciate your cooperation. Sincerely, Hiraku Sakamoto, Tokyo Tech, JQ1YCZ

Dear all,
As we have twitted from our Twitter account: https://twitter.com/OrigamiSat1/status/1134025376936579079
We have send the command for the FO-98 (OrigamiSat-1) to activate 5.84GHz transmission for 10 minutes during the following window.
31.05.2019 14:30-14:40 (UTC)
But please note that, since our satellite is losing UHF downlink capability, we do not know if the satellite really received the command or not.
We will try to send the command for the following windows, too.
01.06.2019 01:10-01:19 (UTC) 01.06.2019 14:11-14:20 (UTC)
We will update the command sending status via Twitter, so please follow our account.
If you received anything, please send us the reception report asap via either of the following methods: Report form: http://www.origami.titech.ac.jp/archives/722 Email: report@origami.titech.ac.jp or Twitter. Thank you very much again for your amazing cooperation. Sincerely, Hiraku Sakamoto, Tokyo Tech, JQ1YCZ
