[GCARC] Cross-band repeater now operational on the ISS!

[djgrath1]

I heard it! An HT tuned to 437.800 MHz. For about 4-5 minutes in my
backyard, I heard callsigns. And for about a minute, they came in very
clear, but disappeared very quickly. At 14,00 miles per hours, there is not
much of a window. But I was happy I could hear the ISS.

Thank Jon.

It appears that the new ARISS (Amateur Radio aboard the International Space
Station) repeater is now operational! It's an FM repeater with uplink on 2
meters and downlink on 70 cm. The radio itself is a Kenwood D710GA that was
highly modified to be certified for space flight along with a custom-built
power supply. K2QA, K2ZA and I got to see this setup at the AMSAT convention
last year and hear about the modifications that were necessary for space
certification - lots of criteria that don't matter to ground-based users.
The attached article describes a QSO running only a few watts on a low pass,
so apparently it's pretty easy to work. We're going to give it a first try
from the clubhouse tomorrow AM and will report back on our progress.

For those interested in trying it there's a high pass at 8:57 tomorrow AM.
For additional passes use heavens-above.com, set your QTH in the user window
on the upper-right (easiest to simply let the website grab your browser
location) and then click on ISS. Be sure to click on ALL passes - otherwise
you'll only see the ones that are visible to the eye.
