With all cubesat launches using the Minotaur 1 and the DNEPR rockets one could almost forget the last Cubesat that is launched from the ISS Kibo module. Here a beautiful image from that launch.
As far as I know there is no data received from this satellite. More information can be found at the TechEdSat website.
The launch as you can see in this Youtube movie below was a success, the launch took place at 07:10 UTC from the Dombarovskiy facility.
Just a couple of minutes after the launch signals where received from FUNcube-1, these came from Amateur Radio Stations in South Africa and they filled the FUNcube-1 data warehouse for the first time.
My first pass was at 08:46 UTC and I had to make up my mind on with cubesats to track. I finally choose for monitor and record a frequency span between 437.350 – 437.540. In the middle of this span would CubeBUG-2 transmit its data. In meantime listen to Delfi-n3Xt at 145.870. When the pass started it was a overwhelming. Delfi-n3Xt pass coming via the VHF Icom 910H and the 192khz span of the FUNcube Dongle Pro+ showed a lot of signals being received. I wasn’t able to decode any 2400 baud BPSK signal from Delfi-n3Xt but after the pass when I analysed the IQ file that was recorded with SDR# I could decode signals from ZAcube-1, UWE-3 and CubeBUG-2.
The following frames are decoded from a recorded SDR IQ file, therefor the timestamps are of.

So far so good, I have 2Gb of IQ data that can be analyzed. This is what I can tell so far, the launch is a success and there are some teams that are still searching for there satellites. Good luck all, I’ll point my antenna’s to the sky when I am able to.
After analyzing the IQ files I also saw the data from Humsat-D, very strong 1200 baud GMSK data and Morse code, modulation type FM. Very difficult to decode the CW data. It is time I learned CW because the Computer isn’t able to decode the data.
Below an image with from left to right: HumSat-D CW, ZAcube 1k2 AFSK and UWE-3 9k6 FSK.
The first three are launched from the Kibo module.
The cubesats: Pico Dragon, Ardusat-1 and Ardusat-X are successfully launch from the Japanese Kibo module. TechEdsat will be launched tomorrow from the same module.
JE9PEL, Mineo Wakita heard and recorded the CW signals from PicoDragon. The satellite transmits on 437.250MHz with CW modulation. Here a link to the recording from JE9PEL listen to Pico Dragon.
The decoded CW: “PICODRAGON VIETNAM 5”
Video is no longer available
The latest update 19-11 20:00 UTC: Pico Dragon frequency offset was around +3.0 to +3.5 kHz. A powerful & clear signal. Decoding CW was even possible in low EL(6deg).
[PE0SAT Thanks JE9PEL, Mineo Wakita for the above information]
Unfortunately we have discovered a major problem with our telemetry client DUDe which makes abusive connections to our telemetry server (even without frames being received) which leads to a collapse of our server eventually. We have tested our system, but not apparently not extensively enough to discover this before we made the system publically available. I would kindly like to ask you to close the DUDe client directly if you currently have this running. We will try to fix this problem as soon as we can and release a new version of the client before the launch.

Delfi-n3Xt sends it data in BPSK modulation on the VHF band. For demodulation using a PC and sound card, you need to tune about 1600 Hz below the VHF downlink frequency of 145.870 MHz (upper sideband) and correct for the Doppler effect. The Doppler frequency can by identified by tracking software. For some combinations of tracking software and receivers, you can automate the Doppler corrections.
To participate in the gathering of data you need a Delfi-n3Xt radio amateur account. Once you have an account you can log in to the server with DUDe to automatically submit demodulated frames and on the radio amateur website to view your submitted data or change your profile. You can register and log in via the following url: DUDe Telemetry Client.
(Please note that your Delfi-C³ account is not valid for Delfi-n3Xt.)
The FUNcube dashboard software is available at the following location: download. Together with the software, there are also guidance Notes that can be downloaded from here: download – please read them before loading and running the software!
Make sure that the pre-requisites apply before installing and running this software. Prior to updating your station with the capability to receive the FUNcube telemetry, please take a moment to ensure that you register at the FUNcube Data Warehouse at http://warehouse.funcube.org.uk/
