The 5840.0 MHz downlink of FITSAT-1 was received in Vermont on both Saturday and Sunday by Mike Seguin N1JEZ.
This video by radio amateur Tetsurou Satou JA0CAW shows reception in Japan of the 5840.0 MHz downlink from the FITSAT-1 (aka NIWAKA) CubeSat that was deployed from the ISS on October 4.
The amateur radio CubeSat FITSAT-1 (aka NIWAKA) carries an Optical Communications experiment that aims to write Morse Code across the night sky. The satellite is fitted with a bank of high power LEDs that will be driven with 200W pulses to produce extremely bright flashes that may be visible to the unaided eye.
On Sunday, October 7 Takushi Tanaka JA6AVG provided this update:
We have received a lot of signal and telemetry reports from amsat members. All reports show FITSAT-1 starts working and sound. Thank you very much for your help.
We will examine movements, temperatures, and battery states of FITSAT-1 during these 10 days, and start experiments of 5.8GHz transmission and flashing LEDs.
I will announce the experiments on my web-page http://www.fit.ac.jp/~tanaka/fitsat.shtml
As well as 437.250 MHz and 437.445 MHz (both +/- 10 kHz Doppler) this innovative satellite can also transmit on 5840.0 MHz (+/- 134 kHz Doppler).
Howard Long G6LVB has released a video showing reception of the FITSAT-1 CubeSat 437.250 MHz CW beacon using just a 1/4 wave antenna on a baking tray sat on his balcony in London. The receiver was a FUNcube Dongle Pro+ LF/MF/HF/VHF/UHF Software Defined Radio (SDR). No preamp or external filtering were used.
