[TheList] ISS Comms

A vertical antenna is not really the ideal configuration as it's radiation
pattern is mostly towards the horizon.

If someone was interested in making contact either through the on board
repeater or with the astronauts on the rare occasions they do speak to hams,
then a dipole or pair of crossed dipoles facing upwards would be more
suited.

'Urro,

I've managed to get a packet back off the APRS repeater onboard a couple of
times, and heard voice on 145.8 in June last year.  Someone in VK7
(Tasmania) working the ISS on a fairly low elevation pass for us.  I tried
both the VHF uplink frequencies and didn't get a reply though.

If you can decode the APRS you'll quite often see packets coming back from
ZL3REW down in Ashburton, he quite often works it, and I've heard him using
the VHF uplink frequencies as well but not heard him talking to anyone yet.

I'm just using a 3m dual-band colinear above roof height, and given it's
line of site just about any antenna/RX should do the job.  Some folks report
working the ISS with just a handheld and decent quality whip antenna.

I have a cunning plan to put up a steerable U/V pair of yagi's to give the
ISS and amsats a proper go but that requires quite a few more round-toit's
than I seem to be able to find right now...  Where did I put them I wonder?

Cheers, Chris H.
