Don't be - you're right on both counts. If the astronauts are busy,
they will at times turn on the packet system on the Kenwood (or use the
old TNC that's been up there for awhile). They use the same freq -
145.80 - whether working voice or the packet mailbox. The uplink freqs
are what is different.

If you are interested in hearing amateur radio operators work through
the onboard amateur repeater on the International Space Station there
will be a pass over the southeastern United States today, September 30,
from 1636-1646Z (1236-1246 EDT). The downlink frequency is 145.800 mhz
FM and if you want to listen for a nearby ham op the uplink is 437.800
mhz. FM. The ISS is at an altitude of 240 miles and easily heard. Take
into consideration the Doppler effect and at the start of the pass start
listening down in frequency 145.790 and move up in frequency as the bird
passes overhead to up in frequency to 145.810 mhz. Would be interesting
to see who hears it and your location. And if you want more data posted
about other satellites and when and where to listen just let me know.
Good luck. Pat K4AVO
