Since the amateur radio F-1 CubeSat was deployed from the International Space Station (ISS) on October 4 there have been no confirmed reception reports.
The attempts to recover the CubeSat are now focusing on reception of the backup UHF FM channel 437.485 MHz (+/-10 kHz Doppler shift). This FM beacon should transmit Morse Code for 20 seconds every 80 seconds during daylight.
The team would appreciate any reports of the beacon which can be sent to Thu Trong Vu XV9AA at email@example.com
The FPT University FSpace team have issued a statement:
Thu Trong Vu XV9AA has provided this update on F-1:
Despite many efforts from the amateur radio community and the team ourselves in tracking F-1, we still haven’t heard from F-1 other than a few uncertain reports during the first few days. The team has been collecting information, analyzing different scenarios and experimenting with F-1′s backup unit in the laboratory. However communication with our American partner to trace back information about F-1 when it was in the States is limited due to ITAR. We hope to come up with an official report about the satellite status by November 4th, and this is not the final conclusion. Thank you for all your support and please continue to help us tracking F-1 if possible!
Nguyễn Trần Hoàng has plotted the descent of the F-1 CubeSat in the 3 weeks since its deployment from the International Space Station (ISS). He comments that the altitude of F-1 appears to be falling faster than the ISS.

The F-1 CubeSat, callsign XV1VN, developed by the FSpace team of young engineers and students at the FPT University, deployed from the International Space Station (ISS) on Thursday, October 4 at 15:44 UT. A Google English newspaper report with pictures of the F-1 team’s attempts to receive the satellite after deployment can be seen at

So far the team has received several mixed reports about F-1 status, there is no definite conclusion yet. We will continue to collect information and analyze the situation, this afternoon we will hold a team meeting to discuss different situations that may happen with the little satellite up there. Please continue to help us listening for F-1 on 437.485 in daylight and 145.980 in the dark, thank you!
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
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).
On October 4, 2012 five CubeSats were successfully deployed from the International Space Station (ISS). The first pod containing RAIKO and WE-WISH was deployed at 1437 UT while the second pod containing FITSAT-1, F-1 and TechEdSat deployed at 1544 UT. Pictures can be seen at
Four of the CubeSats carry Amateur Radio payloads, they are TechEdSat, F-1, FITSAT-1, and WE-WISH. As of Oct 5, 1015 UT signals had been reported from WE-WISH and FITSAT-1 as well as weak signal reports for TechEdSat.
