Re: [amsat-bb] Who is Midori ?
I can offer a better explanation ;)
It's the daughter of Steve Greenland, the UKube-1 systems engineer. He got
to pick the default CW beacon and the AX.25 TO Address when ordering the
radio, and picked his daughters name.
Midori means green in Japanese If I understand it correctly, which makes it
a nice name in combination with her last name Greenland.

Hi Peter, At the moment there is no schedule as the UKube-1 team continues their work to commission the satellite. When the FUNcube team has a schedule available, we will make this know on our website and by E-mail to this BB.

[amsat-bb] QB50 precursor satellites receive OSCAR numbers
Hi All, The QB50 precursor satellites, launched on 19th of June 2014, are in good health and still being commissioned.These satellites are part of a risk-reduction program for the QB50 main mission. Read all about QB50 on the project website at https://qb50.eu/ These satellites are also carrying amateur radio transponders: - QB50p1 carries the FUNcube-3 transponder system by AMSAT-UK and AMSAT-NL - QB50p2 carries an FM transponder by AMSAT-Francophone I am grateful to be able to announce that these two CubeSat Satellites have been awarded OSCAR numbers by AMSAT-NA: QB50p1 shall be known as European OSCAR 79 or EO-79, and QB50p2 shall be known as European OSCAR 80 or EO-80. Thank you AMSAT-NA! The transponders are expected to be switched on after the main mission, which lasts about 6 months depending on progress made. Details about sending in reports and decoding the beacons can be found on the ISIS Ham page at http://isispace.nl/HAM/qb50p.html Mike DK3WN has kindly made and published a decoder at his website: http://www.dk3wn.info/software.shtml based on the published formats.

The spacecraft is still operational, telemetry only, on 145.870 USB Delfi-C3 has exceeded its mission lifetime by six times now, and on-board telemetry still does not indicate degradation in performance. So far, our distributed ground station network (DGSN) has collected 2037513 frames as of today, received by 376 registered radio amateurs and many more on the guest account, using the free RASCAL software. This would not have been possible without your continued support. Thank you!

[amsat-bb] Re: N American Satellite Activity UP
A small correction to JoAnnes Email: FUNcube boards are also able to run both TLM and voice. Thats actually what it is always doing in transponder mode. only the TLM is brought down 9dBs to allow for the transponder power. This 9dB number is also settable in the on board software, so it need not be 9dB. However, this seems to be a reasonable number, as well equipped stations can still copy the TLM easily, and on quiet RF environments, so does an arrow + FT817 or FUNcube dongle. FUNcube boards are now in three more missions, of which two are scheduled for launch this year. Thanks JoAnne for pointing out the existence of these boards, and lets hope some more CubeSat teams decide to use FOX or FUNcube boards. This seems to be the best way for the community to make the best use out of CubeSats for amateur radio. Regarding the world wide collection of telemetry: point at http://warehouse.funcube.org.uk and have them play ;) Or have the students download and analyze ARISSat-1 telemetry at http://www.arissattlm.org/ Another statistic: The Delfi-C3 telemetry collection database now contains 2016683 frames and has 375 signed up radio amateurs submitting data, and many more on the guest account.

[amsat-bb] Re: Two hundred 437 MHz satallites launch March 16 + WebSDR
Howie, CDMA is actually actively promoted by the ITU. Indeed all the details have to be published before launch, so everyone can demodulate it. Citing from the ITU satellite-amateur handbook: *"Amateur and amateur-satellite systems should have technical characteristics that provide worldwide interoperability, and allow origination, relay and termination of communications independent of other radio services. Design emphasis should be placed on reliability, robustness and flexibility of reconfiguration for efficient emergency communications. Multiple access techniques (FDMA, TDMA and CDMA) should be selected for optimum spectrum efficiency and frequency reuse. The selection of modulation techniques should take into account resistance to interference and immunity to adverse propagation conditions."* I have been researching this for the QB50 mission, but strong pressures (mainly from the US) within the project killed the idea early on. The US is now actively putting satellites in 70cm with experimental licenses, which unfortunately means they could use CDMA without providing the spreading codes. The (majority of the) rest of the world is still using the amateur satellite service. Using CDMA would be beneficial for sharing the spectrum, but required coordination as well. I was trying to standardize the parameters (for QB50), so the IARU could be handing out orthogonal codes to satellite teams, so avoid clashes. But welcome to politics.

Hi Robert, You can use the FUNcube dashboard, located at http://funcube.org.uk/working-documents/funcube-telemetry-dashboard/together with your favorite satellite tracking application for controlling rotators (if any). You do not need any other application to control the dongle but the dashboard, but may find it useful to see a waterfall plot with for instance SDR# (http://sdrsharp.com/) The dashboard does not take exclusive control over the dongle, so you may use other applications to tune it. This is not necessary however. 73 Wouter PA3WEG FUNcube team On Sat, Feb 15, 2014 at 11:45 AM, Robert Turlington wrote: > Can anyone recommend suitable software for the Funcube dongle please? > > Regards Robert G8ATE > ___ > Sent via AMSAT-BB@amsat.org.

[amsat-bb] Re: Funcube-1 is +10 kHz on the uplink?
Hi Henk, What you are seeing is the combined effect of various oscillators drifting over temperature and some static offsets present. It is not so easy to have these offsets quantified as static numbers. The oscillators were designed to be extremely low power, and temperature compensation is therefore limited. we do not have the power on board for PLL based frequency generation. With the current state of the art, this is possible, but not when the circuit was designed. The power budget of a one Unit CubeSat is challenging, and FUNcube is the first 1U CubeSat to include a linear transponder. At the moment we are nice and power positive, but the system was designed with the degradation of the battery and solar arrays in mind. So in the end, I am afraid you will have to guesstimate based on temperature.

[amsat-bb] Re: AO-73 QSOs on the beacon?
Hi All, >From a design perspective, the transponder would require about 30 to 40dB more uplink power to produce a signal overlapping the telemetry. That signal would then be a maximum of 9dB above telemetry, compared to the rest of the transponder. Since the transponder is used, the power spreads between users, further reducing the effect. The telemetry signal and transponder are combined, with the telemetry stepped down 9dB, and the filter rejection for the transponder at the telemetry frequency is better than 30dB (40dB with some ripple, I measured 35dB rejection on the engineering model) The AGC acts on the composite output, so if no-one is on the main passband, the transponder will start running full gain (43dB extra). This will possibly reduce the required uplink power to actually overlap the telemetry. But this only happens on high power uplinks combined with no-one running in the main passband. As soon as someone triggers the AGC with a signal in the main passband, the AGC will kill the overlap. There also is FM-ing of the telemetry beacon, but this effect is small (~100Hz), and the BPSK decoder can cope with it. I think it is more likely that AO-7 was up, or some local intermod is producing this effect, but this effect being on the satellite can not be completely excluded. Thanks for sharing this information!

Folks, We have reason to believe that FUNcube-1 / AO-73 is object 2013-066B We would at this point be very interested in comparisons between reception using the older KEPS and the just released KEPS. These are in tle-new.txt on celestrak, and probably on other servers as well. Please keep in mind that due to the initial inaccuracy and the small size of objects, the object designators can change during this phase.

Yes, FUNcube-1, FUNcube-2 on UKube-1, Delfi-n3Xt, FOX-1 and 2 and KletsKous will all have transponders and Delfi-C3 had one. Turksat-3usat also contains a transponder that only worked very briefly. And please amend if I forgot one. Regarding the Space News article: not only the role of ITU is not completely accurate, there is more shortcuts taken. The important thing is to at least make the CubeSat builders aware.

Hi Alan and BB, I also noticed this in GMAIL. It is important that people press the "not spam" button in GMAIL, so that the smart filters do not detect it as spam anymore. I believe Google aggregates these button presses and adjusts the filters. So if enough people detect it as not being spam, it will get off the list. Spam filtering is always a delicate task...especially in radio amateur E-mails, where all the Q-codes and acronyms do not produce valid, grammatically correct sentences ;) Wouter PA3WEG On Wed, Aug 28, 2013 at 9:10 PM, Alan wrote: > Hi, > > Several people have reported that they did not receive their ANS mailings > recently.

I have heard the Phonesats already quite often, and for instance Mike DK3WN does not post every success, but checking his website reveals he receives it almost every orbit when possible. I'm sure there is plenty of people listening. links: http://oscar.dcarr.org/ http://www.dk3wn.info/p/ http://www.pa3weg.nl/?id=news Also note that I'm uploading my packets to the PhoneSat website, but the parser does not eat up my AX.25 output nor KISS.

[amsat-bb] Re: Digital Slow Scan in space
Hi All, SSDV indeed shows you the images "as they come in" Most High Altitude Balloons use RTTY with relatively slow baudrates. The balloons are limited to using FSK modems in the ISM bands, because of legal issues. Therefore, RTTY is the most feasable mode. Tim Zaman here in the Netherlands has run 1200bd RTTY before on a balloon. see http://www.timzaman.com/?page_id=1106&lang=en He used the faster baudrate to send bigger pictures in the same time and was running two baudrates alternating. For satellites, you could run a more complex downlink off course, with less transmission time and FEC. 64QAM might work on bigger sats, but I think it is not feasible for a one or 2u satellite at the moment. I would place my bet on flying BPSK/QPSK for now, and more complex things later. Needless to say that I agree with David about the handshaking and ACKs, but the balloons don't do that either. I do not know anything on HF SSTV, but I have seen SSDV working just fine.

[amsat-bb] Re: Satellite Usage - 2012
Hi List, If I may add to the conversation about linear birds, that Delfi-C3 (an CubeSat!) has had a linear transponder which was used quite a lot. Unfortunately, it was a short lived service, but it proves the point. I'm not sure why people also keep saying that CubeSats are no good, since linear transponders are perfectly possible and 6U and 12U platforms are seen as the way forward there. If we can not launch a fully fledged MicroSat or bigger, why not launch some useful cubes in the mean time? Typing this while working on FUNcube...

[amsat-bb] Delfi-C3 1000 days in orbit
Hi All, Today is the 1000th day in orbit for Delfi-C3. The downlink is still ok and telemetry shows no big degradations. This means Delfi-C3 is still in good health. Apart from the problems with the transponder and some occasional resets and lockups, scientific data is still being received. Also, this data is still forwarded by radio amateurs to our server. Once again our big thanks for receiving Delfi-C3 and your continued support of the project. 73 On behalf of the Delfi-C3 team Wouter Weggelaar PA3WEG ___ Sent via AMSAT-BB@amsat.org.

Hi All, Indeed, Delfi-C3 has quite high temperature extremes on the Cells. This data can also be viewed in the IV-curve display of RASCAL (it displays current temperature of the cell) The temperature is measured with thermistor strips.

Hi All, While Delfi-C3 is rapidly approaching her second birthday on 28th of April, the team got a warning from The United States Joint Space Operations Center about a close approach of COSMOS debris and Delfi-C3. Today at 14:49 UTC the two objects will approach each other almost heads on with a difference velocity of 15km/s (yes, kilometers a second!). Fortunately, the predicted distance between the objects will be 492m, so they will miss each other. Although these close approach warnings were given to other satellites as well, and the chance that something really happens is very small, we would like to encourage people to listen for Delfi-C3 and send in telemetry. Please have a look at the mission operations page at http://www.delfic3.nl/index.php?option=com_content&task=view&id=93&Itemid=122 for frequency info and the latest RASCAL downoad. **PLEASE NOTE** Due to Delfi-C3s habit of sometimes switching off from science mode, you might hear nothing while Delfi-C3 is fine.

[amsat-bb] Delfi-C3 update January 10 2010
Hi all, Recently, we have released an updated version of the RASCAL software for the reception of Delfi-C3 (DO-64) telemetry. You can grab a copy at http://www.delfic3.nl/rascal If you already have RASCAL installed, you can use the upgrade package. The upgrade package leaves all your settings intact. Improvements: - Current & voltage of reference diodes added. This is a measure for the solar intensity received on the solar panels. These diode outputs correlate with the output of the TFSC measurements, and can be found in the IV-curves window (Options -> Show IV Curves) - AWSS data presence indicators added. These indicators light up green if data from the sun sensors (AWSS) is received, and in which quadrant there is data. The AWSS data presence indicators can be found in the lower right corner of the RASCAL main screen. In the mean time, Delfi-C3 is still in good health and performing fine in science mode. The total number of frames as of today is 849670 (approx. 121.5 MB) and the number of registered users is now at 335. Many people are submitting data on the guest account (RASCAL default). Delfi-C3 has been on orbit for 622 days and her second birthday is coming up on April 28th. There are no signs of considerable degradation in science mode, so everything is still healthy. Thank you for your continued support and efforts to receive and send in telemetry data. 73 and Happy new year on behalf of the Delfi-C3 / DO-64 team, Wouter Weggelaar PA3WEG ___ Sent via amsat...@amsat.org.
