>>The $50sat team is celebrating 90 days in orbit by proposing a technical challenge to all interested amateurs. $50sat is capable of responding to uplink command packets:
>>There are 3 open packets: Test packet - $50SAT responds by sending the RSSI of the received packet in slow FM Morse. Request data packet - the normal data packet is sent. Request RTTY - The RTTY is sent. In addition all received packets result in
 two copies of the ack packet being sent, that contains the RSSI of the received packet.
>>All the required information to accomplish this is available on the drop box
 location available through the $50sat web page at www.50dollarsat.info .
>>Anyone that can demonstrate a successful command uplink by submitting a recording of the response packet along with the date, time and location of of the contact will receive aCertificate of Technical Accomplishment signed by all three builders of $50sat.  Submissions can be madeto the $50sat email address; 50dollarsat at yahoo.com.  This is a significant challenge because there is no magic black box that you can buy to do this. 
>>After 90 days of operation, the Kodak KLIC-7002 camera battery that powers the satellite has fallen off about 100mV, but operations still seem normal.
>>We have also programmed a special 5th morse beacon to thank our launch sponsor and mentor prof. Bob Twiggs. Please give a listen for  the message TNX KE6QMD on the FM Morse beacon.
>>QSL cards are still available to anyone that
 posts telemetry, either hand copied CW or RTTY captures,
 to the 50dollarsat yahoo group. 
>>73 and good luck to all from the $50sat team
