In front of scores of audiences over the years, I have never disappointed
audiences and failed to hear SO-50 -  without ever using a pre-amp with
either my tape measure beam or Arrow Satellite antennas ...

Such handheld ops, as low as 10-15 degrees of elevation, can be worked
without a pre-amp.

I'd hate to see you invest in a 440 pre-amp, when the next "big" easily
worked project will have a 2M downlink ... (grin)

Thanks for all the responses on SO-50 preamps and portable setups. I'm
still digesting the info.

TL;DR: I heard automated packet transmissions on the ISS packet
frequency when the ISS wasn't in sight and recorded them to try and
figure out who/what they are, but my software isn't decoding anything.
Can you help me understand what they were, or even better, decode them
yourself?

Here's another question that has me excited:

Yesterday after having visited with family in Maplewood, New Jersey
for several days, I drove home to North Carolina. I knew there was an
ISS pass at 10:26 AM/1426 UTC, right when I started my trip, so I
tuned to 145.825 MHz and heard its digipeater easily.

Then I left the radio on.

I'm not sure where I was in NJ, but about one hour later, around 11:33
AM local/1533 UTC, I heard packet on the frequency again but I was
confused because there weren't supposed to be any more passes for a
while. I confirmed on my phone that the ISS was over some far away
ocean at the time I was hearing these new transmissions, so I knew
they must be terrestrial. Still, it seemed odd that someone or
something was transmitting when the ISS wasn't in sight...

Maybe it's an internet gateway I thought. Or do people leave their
stations on the ISS frequency 24/7 so they can "work" any pass that
happens?

I tried recording videos of the transmissions for later decoding to
figure out who or what it was. Eventually I realized it was
transmitting every 2 minutes. It was almost certainly an automated
setup, adding credence to the idea that this was an internet gateway.
Unfortunately, before I realized that, and after recording one video
of it, the best reception I received during my drive by "pass," I
wasn't recording. As I drove further away it only got weaker and
weaker. I did manage to get two half way decent recordings of it, but
I have tried decoding them with Soundmodem on Windows and it's not
printing out anything like it normally does. I am very new to packet,
only becoming interested in it because the ISS uses it, so I thought
maybe someone else might be more equipped to decode it. Or certainly
someone could shed some light on what I heard, maybe the operator in
NJ is on this list.

I used Audacity to record the audio off the videos I made as well trim
and amplify the audio, but I haven't done anything else, though if
someone wants the unedited videos I can put them up too.

For the packet data take a look at UISS software... also for those SSTV
transmissions from the ISS look at RX-SSTV..

You will also need a packet engine...

Here is what I use

I could be wrong, but it's possible you may have heard a different
satellite transmitting.   It's also possible and more likely, you heard
someone with their APRS or Packet station on the wrong frequency.   This
occurs occasionally with certain dual band radios with built in packet
modems like the D700/D710 or the Alinco 635 in that they are in a packet or
APRS mode and for whatever reason, the operator changes to a different
frequency on that side of the radio w/o shutting off the data
capability.    It can happen on single band radios as well but not as
often, it's easy to do it with the dual band radios.  This occurs all to
often all over the country.  I hear it once or twice a month on repeater
and simplex frequencies in my area so I know it's a widespread occurrence.

John,
Almost forgot... those are basically APRS packets you are hearing..
so to test your setup prior to waiting for the ISS to fly over tune your
radio to 144.39 to listen a test the software...

Then when it's working to your satisfaction tune back over to the ISS data
and listen away...

Thanks

David

Basically they are AX.25 packets NOT APRS packets.  I know that on my radio
(D710), the setup to work the ISS via packet is different from the normal
APRS setup.  It's been a while since I've done either on that radio, but I
do know that the setups are mutually exclusive.

They are probably from PCSAT (NO44) which also acts like a digipeater on
145.825 when sun angles are good.  But PCSAT is *barely alive*.  It can
barely do one or two packet users per pass before the batteries die again
(every orbit).

You can hear PCSAT more than you can decode it, since the batteries are so
weak, they usually cannot even finish a single packet before the TX power
drops off to nothing.  So you never decode bcause  you don't get the valid
checksum at the end.  You might tyry having PASSALL ON...

I'm not sure if we will have a booth there, but the Elk And Arrows are
Dayton only. Sorry.
