FUNcube-1 Dashboard software "Premier Edition" just released
by Graham Shirville 14 Nov '13

14 Nov '13

Hi All, In advance of the FUNcube-1 launch next week on November 21st at 07:10:11 UTC, this first release of the FUNcube Dashboard User Interface software is now available for download here: http://funcube.org.uk/working-documents/funcube-telemetry-dashboard This software, when used with a FUNcube Dongle or other SSB capable VHF receiver, will decode and display all the 58 telemetry channels, all the on-board status flags and also the Fitter messages from the spacecraft. The FUNcube Dashboard will also enable users to upload the telemetry they are receiving to a central Data Warehouse so that others around the world can see what is happening on board. A fully illustrated set of installation and operating guidance notes can also be downloaded from that page. Additionally we also have some IQ and audio files available here that can be used for testing. http://funcube.org.uk/working-documents/telemetry-examples/ Full details of the telemetry format, which has considerable heritage from AO-40, can be found here.http://funcubetest2.files.wordpress.com/2013/08/fun_downlink_data_draf… We are very grateful to our software development team for their efforts in developing the Dashboard and we look forward to your feedback. Please let us have questions and experiences at the FUNcube forum at http://forum.funcube.org.uk/viewforum.php?f=3 best 73 Graham G3VZV

I am tired of D-star thread/argument

I don't have it, don't want it, don't want to hear about it. Lets talk about the new satellites going up.

Call for Symposium Photos
by JoAnne Maenpaa 13 Nov '13

13 Nov '13

Hello Everyone, I would appreciate receiving selected photos, or a link to your on-line albums for photos from the 2013 AMSAT Symposium and Annual General Meeting. With the November/December Journal in-progress it is time to begin planning for full coverage of the Symposium, Banquet, and tour of the Johnson Space Center in the January/February 2014 AMSAT Journal. Please send you photos and/or link information to me by December 1. Thanks! -- 73 de JoAnne K9JKM k9jkm(a)amsat.org Editor, AMSAT Journal

G5500/LVB Tracker question
by Dave Webb KB1PVH 13 Nov '13

13 Nov '13

For the second time in three years, the my az rotor on my G5500 has stopped working. I bought it brand new and I'm using an Easy Rotor Controller for an interface. I noticed that when the rotor is swinging around after reaching its stop that every time SatPC32 sends an updated position to it, it will stop for about a second and then start moving again. I'm not sure if this repeated start-stop is causing the problem. Does the LVB Tracker do the same thing? Thanks Dave-KB1PVH Sent from my Verizon Wireless Droid RAZR

International Designators
by Graham Shirville 13 Nov '13

13 Nov '13

Hi All, At least one of the forthcoming launches is planning to having more than 26 objects being deployed. I think this is the first time that this has occurred. Our TLEs include these references. I understand that after Z is used, the sequence will be AA, AB, AC, AD, etc. Question - will this extra digit disrupt the existing systems we have for distribution of this data or when importing the files into the various prediction programmes that we all use? I may be worrying unnecessarily but ..........just in case! thanks Graham G3VZV

Re: H.E.O.?
by Daniel Schultz 12 Nov '13

12 Nov '13

Keith Crittenden asked: > > I'm interested to know if there are any plans to put a H.E.O. amateur > satellite into orbit in the near future, and if so does anyone have an idea > as to what mode it would be likely to work in? A small committee of AMSAT members was formed at the Houston Symposium to study the issues involved in launching a HEO Cubesat mission. The work is ongoing but conclusions so far are: 1. A HEO Cubesat mission *MIGHT* be feasible under certain circumstances. A lot depends on the launches that will be available in the coming years. 2. It will not be an "Easysat", users will need to invest in some ground station equipment. We can already hear the cries of "elitism" on amsat-bb. The transponder modes are dependent on what antennas can be fit inside and deployed from the Cubesat, and whatever choice we make is going to disappoint somebody somewhere. 3. The present state of AMSAT's financial and human resources will not allow such a launch for at least a couple more years. 4. AMSAT cannot do the mission by itself, there is a need to form strategic partnerships with other organizations to gain access to technology and resources that are needed. If you want to contribute to the committee work please get in touch with me. Dan Schultz N8FGV

Re: D STAR

Hi Jerry, > I use D-STAR Digital Data on 1.2 GHz for my Winlink RMS Packet CMS connection, 24/7. > The Pactor 3 mode that I use for Winlink HF forwarding is proprietary. But nobody else has come up with anything near as good (yet). So a lot of hams use it because it does the job well. I think that was Rob's point. There is no opportunity to learn from it let alone improve upon it because the protocol is at the very least a guarded trade secret if not patented (FWIW, the case of protocols used for HF email mostly outside ham bands I would think there would be very good business reasons for the manufacturer to keep it so). It closes off the doors of learning from it let alone finding ways to improve upon it, and relegates us to nothing more than a consumers of a product. One might argue that ingraining it in a permanent network, whether it be HF email or a shared satellite channel, does more of the same. Having a consumer base that is happy with what they have is pretty good discouragement for incremental innovation....after all, all these consumers have just spent all this money on their radios and modems, why would they want to change or even support it? In the end you may find that "just because it works" sounds specious to people who believe that Amateur Radio Service has had much more to offer than simply transferring information from point A to point B with "maximum efficiency" or whatever. There's a philosophical pragmatism behind this that some people see as having the potential to trump the balance of purposes that define the Amateur Radio Service. I think that's why Rob pointed to the enumerated purposes in CFR part 97.1. (For those outside the US you probably have a similar wording in your countries' laws since this all pretty much summarizes the ITU definition, so this isn't just a "US thing"). (As a side note for the spectators, if you have strong feelings about this you may want think about the long-term consequences the ARRL's upcoming NPRM as it relates to HF digital communication). Back to satellites. I have no idea if D star has a issue with Doppler shift on radios that tune in 5Khz increments of whatever, but it's been suggested that it could be handled with finer tuning, narrower channels, or some kind of AFC. So, you ask your box manufacturer to allow finer tuning (or the chip manufacturer to enable some kind of AFC). They do the market research and decide that you don't represent a big enough market to justify the redesign. If as one commenter has has is true, then you the consumer have no (legal) recourse. Even if you wanted to do improve it your hands are tied. The alternative of having the ability to change and adopt the code to suit various constraints could certainly be handled in an open and possibly very messy manner involving failed experiments but in which everyone has the ability to learn something according to his or her ability if he or she wishes to participate. It sounds like there are people doing just that. (It's the same reason I am on this reflector but don't talk much--I think there are many more, but the list admin would know for sure). Or you can just buy "what works" (works for what?) off the shelf, which is certainly the hope of the commercial interests. But something in my bones (and maybe yours, too) tells me that that kind of pragmatism might not be so good in the long run. It's our future, I guess, and I can't make that decision for anyone, but to dismiss these concerns out of hand in the name of "progress", as it often is, seems rather foolish to me. There's a big picture here that everyone owes it to themselves to take some time to ponder. I'm glad this is being discussed. Cheers, Andy K0SM/2
