Hi Trevor, M5AKA
Thank you for the information.I believe that without the contribution of the Amateur Radio Community all around the word in receiving and collecting TLM as well commanding the satellite the success of Edusat will be a operativeor failure.

The Gauss website at http://www.gaussteam.com/index.php?option=com_content&view=article&i... sat-program&catid=29:unisat&Itemid=195
says regarding frequencies:
"The communication system uses frequencies in the 145MHz band to communicate from ground to satellite (uplink) and frequencies in the 435MHz band for communications from the satellite to earth (downlink). It also provides the S-band."
As I see it there are two issues.
(1) The failure to apply for IARU frequencies. Gauss of course are not alone in this, for example none of the Russian Federation's satellites have gone through IARU coordination. Clearly it is desirable that all Amateur Radio satellite groups go through coordination to minimize interference and enable us to make maximum use of our limited allocations.
(2) The use of 145 MHz for command uplink and 435 MHz for downlinks by satellites that are nothing to do with Amateur Radio and are using the Amateur Satellite Service spectrum for their own private use.
An earlier posting on this list indicated that the 435.750 MHz downlink (and presumably the 145 MHz uplink ?) would only be used when the satellite was in range of Italy.
A subsequent posting indicated that EDUSAT would also be commanded from the United States. I do not have a detailed knowledge of USA Amateur license regulations so I do not know if US Amateurs are permitted to control private non-Amateur spacecraft using Amateur Satellite Service frequencies.

Edusat is a "Non amateur satellite" ? ......OK ,but it has received an experimental license on 435.750 MHz for communicating at no cost into the "Satellite Amateur Frequencies" without coordination from IARU..OK ?
It is very strange that Edusat has received an experimental licence for communications into the Satellite Amateur Band without a frequency coordination from IARU
It is also very strange that the GAUSS group do not officially published the operating frequencies of Edusat stating that those frequencies published via internet are wrong frequencies.
It seems that there is no coordination between our Communication Autority in Roma and IARU as well between the GAUSS group the IARU and the Radio Amateur community.
In conclusion dear Giulio Edusat is a satellite not of our interest and please forget the above box for shoe.

Hi to all the members, knowing that Edusat is not
pretty a cubesat.., I'm
looking for some informations or reports about
the bird, because ,
monitoring the spectrum of UHF and S-Band from
the launch to today , NO
Signals was received from ground stations
in US and EU (same thing for
Nigeriasat) is there a problem on the mission? Thanks for any reports 73 de Giulio AB2VY
