Thanks for the reply and all the links. I’ve been reading a lot and with the Doppler shift (I didn’t even think about that) and all I think I’m going to set up a station just to receive this year. The schedule shows the AO-51 will be set up for JOTA starting Monday so I’m planning to try it out and see how well I do. Hopefully I will be able to receive it OK. I’m also considering set up a PC with tracking software. I’ve been reading up on several of the PC tracking packages but I’m not sure which one to get. I would like to get one that is very graphical and I don’t mind spending some money to purchase. Any idea’s on which one to focus on? Looks link InstaTrack is real popular but I’ve also looked at the NOVA product. Looks like to NOVA is more graphical.
Thanks for the help,

Excellent tutorial at: http://www.amsat. org/amsat- new/echo/ EchoHT.php
... from a collection of papers for beginners http://www.amsat. org/amsat- new/information/ faqs/index. php
An easy place to get started on when the AO-51 is overhead, is http://www.heavens- above.com/
AMSAT sells some excellent software for predictions and there are some “freeware” programs available. See www.ac6v.com as a resource.
AO-51 Operating Schedule at http://www.amsat. org/amsat- new/echo/ ControlTeam. php
Typical pass time for overhead pass is in the order of 10 minutes.
Since the AO-51 will be switched on for QRP operation before JOTA, I recommend you practice working someone on the bird. The AO-51 will primarily be for demonstration purposes, not casual JOTA contacts with scouts ... I suppose that could happen, but, with limited visibility, contacts will be best made by skilled operators and not 3rd parties. Explain to scouts what’s happening, and let them listen in. If you’re using one of the AMSAT software packages, you can have a display of the satellite footprint on display to let them know when the satellite comes in range.
Do the best you can for this JOTA and, then, keep practicing for future demos. Pretty soon, you’ll feel very comfortable with the AO-51 and some of the other LEOs.

Thanks for passing along the info about AO-51. I’ve been a ham for a number of years and involved with Scouts for about 6 years. We had our first JOTA last year and it only involved HF (20M) radios. This year we are including some FM (2m & 70cm) with EchoLink and now I want to do something with AO-51 but I’ve never used any of the satellite communications. Can somebody help me understand what I need to do to add this to our JOTA event?
The way I understand it from reading the amsat.org site is that AO-51 is a satellite that will have 2 repeaters operational during the JOTA weekend. We will need to transmit on VHF with the designated frequency, tone, etc. and receive on the UHF designate frequency. Is it that simple? How do you know when it is within range to operate? How long will it stay in range? This is all really interesting and I’d like to set up a couple of radios on the designated frequencies and maybe printout something showing how we will be communicating through the use of a satellite.
Thanks for passing along this information and I look forward to your response(s),

satellites in the past, since it can be set up for many
different configurations. Sometimes, two different
configurations can be operated at the same time (i.e.,
2m/70cm FM repeater with 2m/70cm 9600bps digital, or
2m/70cm FM repeater with 23cm/70cm FM repeater). The AO-51
configuration for next week, with 2 FM repeaters, has been
used a few times in the recent past including for the ARRL
Field Day in late June.
I am a member of AMSAT's AO-51 Operations Group, which makes
the monthly schedules for this satellite:
http://www.amsat. org/amsat- new/echo/ ControlTeam. php
and we receive e-mails from radio amateurs around the world
at our ao51-modes @ amsat.org (remove spaces around the @
sign) e-mail address. Some request a configuration for an
event like JOTA, Field Day, or a local hamfest. Others want
to try something out at their station and would like one of
the less-common configurations turned on.
If you are set up to work these satellites, give it a try
and post your results. Also, if you could e-mail the
ao51-modes address with the same information, we would
appreciate it. We use these sorts of comments to know if a
particular configuration is popular, meriting its use in the
future. If you'd like to discuss details on setting up for
working this satellite (and others), please e-mail me directly
and we can take care of that. Many 2m/70cm handheld and mobile
radios are able to be used with the FM satellites.
Good luck, and 73!
