ISS Crossband Repeater

Update on the ISS crossband repeater. It should become active shortly after 1245 UTC May 7 (5:45 AM PDT). The APRS system will be off while the crossband repeater is on. A best guess is that the repeater will be operational for around a month before switching back to APRS mode.

Just might be back on May 7, 2021!

And remember - it isn’t the TX power, it is timing (grin). Better results during off-peak hour passes!
