_mo_, May 17, 2004 in Ham Radio
Ummm.... I use satellites all the time... for my GPS!
I've never tried one for HAMing, but I wouldn't mind learning about it.
Gloom, aka W7MVG
I do sats, right up to AO-40 before it died.
What questions did you have?
I don't know what questions I have... I'm just starting to get reading on this.
had my ticket for a little more than a year and have 2 rigs.
older Icom mobile 2m FM job and a Yaesu VX5R.
Looks like with the FM limitation of mine, I'll have to stick to UO-14, AO-27 and daylight passes of SO-41 (from the 2004 ARRL handbook).
I'm going to try listening in on passes the next few days and maybe give transmitting a shot after I get the jist of what goes on. Also thinking about picking up the Arrow antenna that I've read about on just about every webpage that talks about using an HT for the birds.
edit: have to scratch UO-14 from the above list as it's dead.
I have done some sat work. I used to like the RS-13 on CW because there was lots of room for multiple QSOs. It was 2M up and 10M down(receive). The FM sats are fun, but there is room for only one QSO at a time and the most powerful signal gets through...and there are those that like to monopolize the channel.
The arrow antenna works well and I have a friend who owns one and used it with him. I made some contacts with my 50R dual band wtih a long whip once while in the Sierra mountains.
There are some good programs to use to predict the passes. On a Palm PDA, I have used PocketSat.
There are some good programs to use to predict the passes. On a Palm PDA, I have used PocketSat.
I've got PocketSat loaded up but haven't messed with it too much. I've been playing with SatScape for the PC and think I've got it pretty much figured out.
Lots of pretty graphic choices. But the list of predicted passes is what seems the most useful.
Here is some info for you. This will show you the sats available right now. You are right, you are limited to FM. But look carefully, I think some of your data is old. I know for sure that UO-14 is dead!
Here you go.
This report is organized into 3 parts.
Part 1 - operational analog amateur satellites.

Masa, JN1GKZ, reports:
JARL FO-29 command team wants FO-29 reception report.
The recent FO-29 shout down problem is not due to Under Voltage
Controller(UVC). The cause is unkonw. To analyze the problem, command
team wants following info.
1. night pass CW telemetry data
2. analog transponder status (status and the time)
3. the time analog transponder stopped
4. other reference info
Please send the report to email@example.com . Put the subject 'FO-29
reception report' .
This info is from JARL web site. It's only in Japanse...

Reinhard, DJ1KM, reports:
SO-50 is in good health and it is easy to access the satellite. However,
needs to be opened by a controlstation before you can operate theSat. There
are (I believe) 3 controlstations in UK and 2 in DL. I am one ofthese.
satellite comes from a direction where no control station is it is most
probably not switched on.
SO-50 carries several experiments, including a mode
J FM amateur repeater experiment operating on 145.850 MHz uplink and 436.795
MHz downlink.The repeater is available to amateurs worldwide as power
using a67.0 Hertz tone on the uplink, for on-demand activation.

Tonight's passes of RS-15 started out with a strong beacon transmitting

to a continuous carrier lasting upwards to 30 seconds. The frequency
up and down quite a bit as you listen to it. On the 0605 pass once
into eclipse the beacon died altogether. It's hard listening this bird die.

AO-49 (SAFIR-M) is a German amateur radio payload onboard the small German
scientific satellite "RUBIN-2".
AO-49 was built by the German amateur radio association "AATiS e.V." (German
acronym for "Arbeitskreis Amateurfunk und Telekommunikation in der Schule",
which means: 'working group for amateur radio anand telecommunications in
schools'). AO-49 is designed as a "store and broadcast" system for APRS
based messages, dedicated for the use of schools in combination with the
existing WX-Net and planned buoy experiments in Germany.
No transmissions detected since the 1st of February 2003! It appears
AO-49 is not properly aligned to illuminate the solar panels. This
should end soon. Due to its orbit, AO-49 will be in a phase without
eclipses until 13Feb03.
Martin DG8UAU has written a small software program "SAFIR-M Decoder" to
allow decoding of the received DATA0 frames. It is available at:
http://amend.gmxhome.de in the section Aktuelles.
Details on AO-49 (SAFIR-M) can be found at:
