My first APRS Packet on ISS

Today I've sent and repeated my first APRS Packet through the International Space Station ISS.

The aprs path was ARISS.
Equipment:

TH-D7  many years old
Wimo sota Log Periodic Antenna
Power about 3 watt


During the pass I've "READ" a lot of other stations from all over Europe.
Being from Suedtirol, Dolomity Mountains, my message was Italy Dolomiti.

So the belove screenshot is like a qsl for me.
You can seen on the balloon that i was repeated by RS0ISS :

A tribute to UO-11

In just six months time engineers at the University of Surrey developed, built and launched on 01-03-1984 UoSAT-2 as a piggyback payload aboard a U.S. Thor-Delta rocket carrying the LANDSAT-D earth observation satellite from Vandenberg Air Force base in the orbit.

With 70 kg was UoSAT-2, the first satellite with advanced digital “store-and-forward (email)”


UO-11 is not operative but sometimes, when it's on sunlight it begin to transmit the telemetry on 145.826 Mhz.


Here it's possible to see the update status of this satellite along many others:


Oscar satellite status


This is a audio recording that I've personally made of the UO-11 telemetry sound:

QIKcom-1 APRS Satellite

 A fresh info from Bob, WB4aPR




APRS Satellite operators:

http://aprs.org/qikcom-1.html


We are delivering our next APRS satellite (QIKcom-1) next week and it will
have a mission life of maybe 6 months.



It is a very quick reaction short fuse opportunity so we are simply going
to fly an APRS digipeater (TinyTrack4) supporting the three digipeater
aliases of ARISS, APRSAT and WIDEn-N but it will operate at 4 Watts RF
power and be easily heard on any HT..



It has no other CPU on board and so it flies with only the fixed settings
set before launch.



But we do have an A/B switch which can be used to switch between two bank
settings.

I just cannot think of any neat must-do ideas for how to use the other bank
settings.



The host spacecraft has plenty of power, so there is no need for low power
options… (they can simply turn us off if needed).  Telemetry is a boring
Volts, current, and two internal temps.  The settings in bank 0 are now:



DIGIPEATER:  ON

ALIASES:          ARISS, APRSAT, WIDEn-N

BTEXT:              USNA-W3ADO APRS Satellite every 2 minutes

TELEMETRY:   every 1 minute.



I just cannot think of any use for a separate bank settings?



If you have ideas of how to use the A/B settings let me know.

First sat qso's

My portable and qrp sat station, 31 August 2013 first qso with so-50.

Work condition:

• FT817
• Icom 706 first version
• VPA system antenna http://www.vpa-systems.pl/crossband-yagis-144430-c-23.html
• Home made high pass filter
• CAT control
• SAT PC 32 in demo mode
• Netbook
• Car Battery

Until now I was able to work so-50 and fo-29, but the power on uhf is to low for AO-7 and Vo-52
