These squares seem rare to me. I was wondering what the desire for them
would be. I would have to make a special effort to hit CO60 but I would do
it if there are a bunch of people that want it. Let me know. I would be
operating FM sats and APRS packet with my HT and Arrow from these areas.
73 de Pat --- KA9SCF.
Due to some money issues, I had to sell all my sat gear including my
beloved TS-2000X. I've been going through some of my old gear and
rustled up a Radio shack VHF/UHF scanner that covers ham frequencies. Do
you think it would be possible to hear the FM sats with it? I have a
homebrew 11 element linearly polarized yagi and I can still track the
sats via computer rotator control.
I can make it where I have a short run of cable to the antennas since I
don't have preamps anymore.
I'm also wondering about using some 75ohm RG6 quad shield satellite TV
cable for receiving. Would this be better or worse than 9913 with the
scanner? Kind of grabbing at straws here but I'm wondering if anyone
thinks it would work before I invest too much time into it.
Tnx and 73,
Again this year, AMSAT will have a booth at the Rochester (NY) Hamfest
on June 1st, 2nd, and 3rd. The following Satellite Demo(s) are

03Jun2007 Sun VO-52* 1630 1642
* For VO-52, I will be on (or about)
The callsign will be "N2SPI/Portable".
If you're on any of these satellites this weekend, listen for us, give
us "a shout", and say hello to crowd observing the demo. We typically
get a dozen, or more, interested observers.
If you're interested in the partially homemade portable station I'll be
using for the FM LEO(s), go to
"http://www.amsat.org/amsat-new/information/faqs/crow". The radios I
use are discussed at the end of the articles. For the Hamfest, the
Hamtronics LNK-450 Preamp and Alinco DJ-S40T UHF HT will be clipped to
my belt and pants pocket on my right side. The Yaesu FT-1802M (or ICOM
IC-2100) 2m "mobile" will be clipped to my belt on my left side. It
will be powered by a homemade NiMH battery pack of 11 "high-current"
sub-C cells in my left pants pocket which easily puts out 10 amps at
14V. For SSB on VO-52, I'll be using a Yaesu FT-290 and FT-790 both
clipped to my belt. This allows me to walk about looking for the best
location to access a given satellite.
I recorded some signals from RAFT yesterday night few hours before the end
I did not decoded it.

I too, would be very interested in those grids as
well, so count me in as another fellow requester for
those areas, along with any others that desire them.
In other words....PICK ME! PICK ME!

Looks like we get one more shot...
Lets everyone that is interested to park their ground station pointing at AOS for RAFT and recording packets. This is a great opportunity to see the heat up of an AMSAT as it re-enters.
Do NOT bother with automatic tracking, since arrival will be much earlier than any keps you can get..
If you can APRS-IGate the packets then that is even better, sinec we can all see the telemetry then in real time.
