[amsat-bb] Frustrated--not hearing ARRISat

Ok, I'm getting very frustrated and I think I need some Elmering. I have
not heard ANYTHING from ARRISat-1, at least nothing intelligible. I'm a
pretty new ham, so I'm getting into it one piece of equipment at a time.
Figured I'd play a bit with a handheld, and then figure out what I needed
next step by step. It's been several steps so far with nothing to show for
it except some pretty hardware and a smaller bank account. I know a few
more things I can do, but I'd really like to know if I have some major
problem here. I'll tell you what I'm trying, and I'd like to know if anyone
has had success with anything similar.
First, I have an M2 2-meter eggbeater antenna. It is inside the house (my
shack is on the 2nd floor, sadly). It has an SSB 2-meter pre-amp, followed
immediately by a Diamond 2m/70cm duplexer into a 25-foot feed line. At that
point it is connected via an adapter to my Kenwood F6A handheld. I also
have an FCD, but with its poor 2-meter filtering, I wanted to eliminate one
A few minutes ago, there was a nice pass from ARRISat-1 here in FN42
(southern NH ); it was in sunlight and had been for some time, should have
been up over 50 degrees elevation. Turned everything on, (oh, yes including
a 13.8V power supply for the preamp, fed separately). My radio tunes in
.005MHz increments, so I started out at 145.955 and tweaked around up and
down, shifting to 145.950 and 145.945 as the sat reached and passed max
elevation. I *may* have heard vaguely down in the static a voice. I *may*
have heard vaguely down in the static some data that might have been SSTV.
I may have imagined it.
I *know* I would get better reception outside; I know I would be better off
with a directional antenna that had more gain. I can see improving things
that way, but is NOTHING a reasonable expectation with this setup? I can
receive the NOAA weather station on 162ish MHz (outside the pre-amp's curve
but I still get it); I have received the ISS without the preamp (I know
that is a lot more power than the sat). So I don't think something is
wildly broken. So my question to you is: Have any of you been able to read
the sat with anything similar? An eggbeater? I thought I remembered
someone receiving on a handheld with a rubber ducky? BTW, someone previous
mentioned that I should try listening to some of the other lower-power sats;
many of them are 70cm downlink and I have not gotten a 70cm antenna yet.
Thanks for any advice or comparisons.
