[Ground-station] Upcoming channelizer test opportunity

[Michelle Thompson]

I have apparently rescheduled the entire contest calendar. Who knew I had
such power. Thanks for the correction!

I have a video I made one year and several photo sets of tuneups from San
Diego Microwave Group. I’ll try and post them in a bit. It’s quite the
sight to see all the rigs lined up.
