So with all the space on 70cm.....
The voice beacon is on the same frequency as AO-51. Is that right ?

David,
And the uplink is on the "QRP" transponder uplink. Joy.

All,
A few months ago I corresponded with the AMSAT-SA webmaster about that. I think it is a typo and the correct frequency is 435.350. As far as the 145.880 frequency being the same as the QRP uplink on AO-51, they are correct in using it. AO-51 is not coordinated on 145.880, and they are. If it causes problems, we'll just have to use a different uplink for the QRP repeater. The 2m satellite subband is very crowded, and there are frequencies in use for cubesats and such that most amateurs are not even aware of.

Drew,
Interesting, and good to know. The flexibility of AO-51 gives us lots of options if needed.

Hi, Drew!!
Lots of amateur satellite frequency information is available to everyone. Suggest seeing:
http://www.amsat.org/amsat-new/satellites/
We have the IARU coordination process to try to work out frequency planning issues, most times before launch!!
I hope this helps.

What we can do is to live out our lives as best we can with purpose, and with love, and with joy. We can use each day to show those who are closest to us how much we care about them, and treat others with the kindness and respect that we wish for ourselves. We can learn from our mistakes and grow from our failures. And we can strive at all costs to make a better world, so that someday, if we are blessed with the chance to look back on our time here, we know that we spent it well; that we made a difference; that our fleeting presence had a lasting impact on the lives of others. - Barak Obama, 29 Aug 2009
Does anyone have any information on the Very Low Frequency (VLF) radio experiment from the University of KwaZulu-Natal that's on the satellite ?

Hi all,
I have just spotted this link for tomorrow's Sumbandilasat Launch - not sure how well it will work tho!

Live coverage of this launch will be on September 15th at http://www.tv-tsenki.com/livechoose.php
Beginning of this coverage - 14:00 UTC, ending - 17:00 UTC. Launch time - 15:55:07.4 UTC.
Dutch authorities propose rebanding D-STAR into 70cm satellite band
Information received from the Netherlands this week indicated a growing threat to frequencies allocated and used by the Amateur Satellite Service.
Worldwide, including the Netherlands, amateur use of frequencies in many portions of the 70cm band are allocated as secondary users.
The threat arises from proposals to move the output frequency band of terrestrial D-STAR repeaters from the 439-440 MHz range down to 437-438 MHz.
Dutch regulators have halted amateur D-STAR repeater licensing in that country because they plan to reallocate 439.500 MHz and upward to the Differential GPS (DGPS) service.
Despite protest from Dutch amateur radio operators, amateur clubs in the surrounding countries, and regulators in nearby countries, it seems as if the Dutch authorities are still planning on this frequency re-allocation to favor DGPS operation in violation of ITU allocations.
If completed this reallocation of the terrestrial D-STAR repeater outputs would place them right in the downlink band of the Amateur Satellite Service. This would have immediate operational impact on European amateur satellite stations. Longer term it may open the door for future infringement on satellite operations in other countries.
Hello,
Yes the SumbandilaSta frequencies are correct. To confirm from the website: http://www.amsatsa.org.za/SumbandilaSat.htm
