There isn’t a trick, it’s that I have admin rights and as Permissions Matrix describes I can schedule on Online and Testing stations.
I use these permissions in most cases for special events like ARISS Contacts or SSTV events, new deployments or critical situations like satellites that stopped or started transmitting. Hopefully soon the automated scheduling will take care all of these scheduling cases.
Indeed my stations are not currently online as they come up and down, used in network-dev.satnogs.org or locally for testing client and network updates and new features that either I’m working on or the rest of the developers develop. Also I’m one of the maintainers of the hackerspace.gr station but for typical reasons not the owner in network.
I hope this doesn’t seem an unfair use of the network and of the stations.
