The FUNcube team has\nselected a few command stations to do so, but be advised the transponder\nmay be off.\n\nTLEs:\nAMSAT keps name: EO-79\nCelestrak keps Name: QB50P1\nCelestrak file: cubesat.txt\nNORAD # 40025\nCOSPAR designator 2014-033-R\n\nFrequencies:\n*Uplink:* 435.035-435.065 MHz LSB\n*Downlink:* 145.935-145.965 MHz USB\n\nEO-79 has been set to only beacon the normal AX.25 beacon every 30 seconds\ninstead of 10 seconds. The beacon frequency is 145.815MHz and consists of\nAX.25 frames on BPSK. more details about the downlink can be found on the\nISIS HAM page at http://isispace.nl/HAM/qb50p.html\n\nWe kindly request you to share your experiences with the BB so everyone can\nbenefit from operating tips and tricks, as well as being up-to-date on the\nstatus.\nWe would also welcome any observation related to the transponder behaviour\nwhen the AX.25 beacon comes on.\n\nJust like FUNcube-1, the crystal oscillator circuits exhibit drift with\ntemperature. This means manual tuning will probably work best.\n\nLastly, the commanding team will not be available over Christmas, so the\ncurrent activations are planned from today until Thursday 24th and from\nMonday 28th until Thursday 31st\n\n73 and have FUN\nHappy Holidays\n\nWouter Weggelaar, PA3WEG\nAMSAT-NL\nAMSAT-UK\n_______________________________________________\nSent via [email protected].
