On Sunday, June 21, there was an anomaly on FUNcube-1 that required the reboot of the satellite’s MCU (Microcontroller).

After a bus freeze, the databus watchdog did kick in as expected and rebooted the satellite. However, we did need to command the satellite back on to automatic mode.

When we did so on the 20:00 UTC pass, it came back up in the correct mode.

We envisage to switch back to autonomous mode either tonight or tomorrow morning local time.

FUNcube is still happy and healthy. This is the 4th reboot since launch, of which one was intentional. Thanks for your reports and concerns.

On behalf of the whole team best 73s,

KLETSkous Project Update

KLETSkous LogoThe South African Radio League (SARL) report at the pre-conference Engineering meeting held on Friday [June 19] members of the SA AMSAT CubeSat team made some tough decisions.

During the past few years, various options and subsystems have been experimented with.

The team has now set the launch date of KLETSkous at July 2017 with the first flight model to be ready by February 2016 for testing after which final integration will start. This requires that various module designs are locked down and built by October 2015.

It is planned to have all the modules wired together in a breadboard configuration for testing the interoperation of the various sub-units by December 2015. Some modules are at a more advanced stage than others, but in the next few months, the team expect to catch up and meet the deadline for the first breadboard test.

Frik Wolff, ZS6FZ, the League’s technical manager, has joined the team and is working on solar panels and stabilisation issues. Francois Oberholzer, an honours student at Stellenbosch University, is working on improving the weight/strength relationship of the space frame, a project that is part of his thesis. Nico van Rensburg, ZS6QL, as programme manager and the person responsible for documentation, will support the project manager, Hannes Coetzee, ZS6BZP.

There are many opportunities for radio amateurs to join the engineering team. If you have a particular expertise or passion to add value to the  KLETSKOUS project, please discuss your participation with Hannes Coetzee or any of the team members and send your details to

QB50p1 and QB50p2 – Image Credit ISIS

AMSAT-Francophone report that the FM transponder on QB50p2 (EO-80) has been tested. A Google English translation of the post on their website reads:

On June 19, 2014, two 2U CubeSats QB50p1 and QB50p2 were launched as part of the QB50 precursor program into a polar orbit at an altitude of 680 km.

The satellite QB50p2 (object 40032) is equipped with a secondary FM transponder payload developed by AMSAT-F.

On Tuesday, June 16, 2015 almost 1 year after launch the AMSAT-F FM transponder on QB50p2 was activated by the main control station in The Netherlands for the duration of an orbit. At the Polytechnique in Palaiseau, we were able to receive telemetry in CW and put into action the FM transponder with an output of 1.5W.

A very strong signal was received at Palaiseau and by F6HCC in Brittany. The transponder was turned off at the end of the orbit.

In a few weeks, the transponder should be activated permanently. The signal is very strong, we will probably use a lower power level of 500 mW or 1 watt. We will inform you later.

QB50p1 (EO-79 / FUNcube-3) is equipped with a linear transponder for SSB and CW. The first tests were successfully completed in April and its transponder should also be enabled full-time in a few weeks.

QB50 Amateur Radio Information


The IARU Satellite Frequency Coordination Panel Status pages list these frequencies for the two satellites:

QB50p1 (FUNcube-3) has a VHF 9600 bps BPSK telemetry downlink plus a linear U/V transponder for SSB/CW communications similar to that already flying on FUNcube-1 with an output of 400 mW.
• 145.815 MHz 9600 bps BPSK telemetry beacon
• Inverting SSB/CW linear transponder 400 mW PEP
– 435.035 – 435.065 MHz Uplink LSB
– 145.965 – 145.935 MHz Downlink USB

QB50p2 has  a VHF 9600 bps BPSK telemetry downlink plus a separate RF payload from AMSAT-Francophone which will comprise of a FM voice transponder with UHF uplink and VHF downlink. It can also transmit FX25 telemetry at 9600 bps.
• 145.880 MHz 9600 bps BPSK telemetry beacon
• 145.840 MHz 9600 bps FSK FX25

To use the FM voice transponder Paul Stoetzer N8HM suggests programming these frequencies into your rig’s memories:

EO-80 AOS - TX 435.070 MHz 210.7 Hz CTCSS, RX 145.840 MHz
EO-80 2   - TX 435.075 MHz 210.7 Hz CTCSS, RX 145.840 MHz
EO-80 TCA - TX 435.080 MHz 210.7 Hz CTCSS, RX 145.840 MHz
EO-80 4   - TX 435.085 MHz 210.7 Hz CTCSS, RX 145.840 MHz
EO-80 LOS - TX 435.090 MHz 210.7 Hz CTCSS, RX 145.840 MHz

AOS = Aquisition Of Signal. TCA = Time of Closest Approach. LOS = Loss Of Signal

Help needed to receive NanosatC-BR1

NanosatC-BR1 Engineering Model – Image CRS/CCR/INPE-MCT, UFSM

NanosatC-BR1 Engineering Model – Image CRS/CCR/INPE-MCT, UFSM

The first Brazilian CubeSat, NanosatC-BR1, is experiencing battery issues for the last several months and it now seldom emits a beacon in CW on 145.865 MHz.

For some time, Paulo PV8DX, was able to detect a beacon signal when the satellite was over the Caribbean sea during daylight. But now, no more signals have been detected.

We would like to request assistance from hams in the northern hemisphere to see if NanosatC-BR1 is still transmitting any signals.

Any help will be much appreciated.

On Thursday, June 11, BBC TV News featured radio amateur Dr Chris Bridges 2E0OBC who was explaining about the FUNcube-1 CubeSat and FUNcube Dongle SDR at the Goonhilly Space Operations training event.

Twenty-four delegates from across Europe and the United States are at Goonhilly Earth Station in Cornwall to learn about satellite communications, and how to control orbiting spacecraft.

The four-day course, which runs until Friday, June 12, is aimed at giving science graduates with an interest in working in the space industry a first-hand idea of operating satellites. Staff said they believed it was the only course of its type in Europe teaching how to operate such equipment.

Chris 2E0OBC appears at 0:33 into the BBC TV report. Watch the video at

Bill Nye “The Science Guy” @BillNye tweeted – This just in: a complete image of ‪#‎LightSail‬ in space! The future of space travel…

The sail started deploying at 1947 UT on June 7, 2015. It is expected that LightSail’s orbit will now decay rapidly resulting in the satellite burning up in the atmosphere in a matter of days.

OSCAR Numbers Assigned for BRICsat (NO-83) and PSAT (NO-84)

PSAT PSK31 Transponder received by Peter Goodhall 2E0SQL May 26, 2015

PSAT PSK31 Transponder received by Peter Goodhall 2E0SQL May 26, 2015

The following message has been sent by the OSCAR Number Administrator Bill Tynan W3XO to Bob Bruninga WB4APR and the team at the US Naval Academy.

You have requested OSCAR numbers for BRICsat and PSAT built by you and your associates at the U.S. Naval Academy.

From everything I can determine, these satellites meet all of the requirements for OSCAR designations.

Therefore, by the authority vested in me by the AMSAT-NA President, I hereby confer the designation, Naval Academy OSCAR 83 on BRICsat and Naval Academy OSCAR 84 on PSAT These designations can, of course, for convenience, be shortened to NO-83 and NO-84.

I, and the entire amateur satellite community, hope for successful missions for both NO-83 and NO-84 and congratulate you and the rest of the Naval Academy team who designed, built and tested these two OSCAR spacecraft.

William A. (Bill) Tynan, W3XO
OSCAR Number Administrator

NO-84 PSAT, a student satellite project named in honor of USNA alum Bradford Parkinson, of GPS fame, contains an APRS transponder for relaying remote telemetry, sensor, and user data from remote users and Amateur Radio environmental experiments or other data sources back to Amateur Radio experimenters via a global network of Internet-linked ground stations.

PSAT is another APRS satelliite that can digipeat user packets just like the original PCSAT (NO44) and the packet system on the ISS. PSAT also supports the same digipeating alias of ARISS so that users do not have to change any parameters when using any of these three APRS transponders.


NO-83 BRICsat-P (Ballistic Reinforced Communication Satellite) is a low cost 1.5U CubeSat built by the US Naval Academy Satellite Lab in  collaboration with George Washington University, that will demonstrate on-orbit operation of a Micro-Cathode Arc Thruster (µCAT) electric propulsion system and carries an Amateur communication payload.


PSAT: 145.825 – 1200 baud AX.25 telemetry – digi off
PSAT PSK31-5: 435.350 FM down, 28.120 SSB PK31 uplink – Brno University

BRICsat: 437.975 – 9600 baud telemetry evry 20s
BRICsat PSK31-6 – same as PSAT but PSK TLM on 375 Hz (PSAT on 315 Hz)

Jason Davis @jasonrdavis reports that LightSail, call sign KK6HIT, is operational again. Nine beacon packets on 437.435 MHz (AX.25, 9600 bps FSK) were received during 2:14 pm EDT pass on June 6, 2015.

Update: The sail started deploying at 1947 UT on June 7, 2015. A fully deployed sail would result in LightSail’s orbit decaying rapidly and burning up in the atmosphere potentially within a matter of days. Amateur radio operators around the world are encouraged to listen for LightSail and submit data. Details can be found at

Martlesham FUNcube Development Workshop Report

Martlesham FUNcube Development Workshop May 30-31, 2015

Martlesham FUNcube Development Workshop May 30-31, 2015

Having two live projects underway is proving an enjoyable challenge for the AMSAT-UK teams involved. Both the Nayif-1 CubeSat and our payload on ESEO will provide similar 1k2 BPSK FUNcube compatible downlinks so the teams have quite a lot in common.

Martlesham FUNcube Workshop 2 - May 30-31 2015The two teams got together for two days at BT’s Adastral Research facilities at Martlesham over the weekend of May 30-31.

As will be more fully reported in the next edition of the “OSCAR News”, the work concentrated on updating the suite of existing FUNcube software for the forthcoming Nayif-1 spacecraft and also the first power on for the combined CCT/EPS (computer and power) board for ESEO with its ATMEL AT32 microprocessor.
