The modulation that the FUNcube satellites use is DBPSK at 1200baud. The coding is based on a CCSDS concatenated code with a convolutional code and Reed-Solomon, but it makes extensive use of interleaving to combat the fading caused by the spin of the spacecraft.

    Hams will be able to earn a Ham Nation 300 certificate by working six of the nine Special Event callsigns. They may also qualify by working five of the nine 1×1 calls and one show host.
    Hams can earn a Clean Sweep certificate by working all nine 1×1 callsigns. Commemorative QSL cards are also available. Hams must send their QSL Card and an SASE to each station.
    A new digital certificate is available for hams with a Technician license. They earn it by working two digital stations in any of the four digital modes.
    Contact the stations on any band. You may look up the details and rules for the on-air event at the QRZ page of the nine 1×1 callsigns above. Check the QRZ.com pages  often as we update them often.

    The Ham Nation Challenge ends August 31, 2017. Hams may earn one of three certificates. Scoring 300 to 499 points will earn you a bronze challenge certificate. If you score 500 to 599 points you will receive a silver certificate. A score of 600 or more of the possible 750 points in the challenge will get you a Gold certificate. Hams receiving the top three scores appear on Ham Nation in September.
    Hams earn challenge points by completing simple tasks like … submitting a chat room question; submitting a video or shack photo for broadcast or scoring a “selfie” with a host or net control operator. 
    By completing the more challenging tasks hams earn more points. More difficult tasks include … becoming a Volunteer Examiner; upgrading their amateur license or earning a WAS or DXCC. We will post a complete list of the challenge tasks and points awarded on each of the 1×1 callsign QRZ pages.

    If you are talking about this event on social media we encourage you to use the hashtag “#HamNation300”.
