Re: [amsat-bb] Question for Gpredict Users
It's not that difficult. I'm going to CC the 'bb on this so anybody else facing the same problem can use this. Also, they should be almost drop-in compatible, but I ran all of this on a Linux Mint install, not Ubuntu. Mint (IMHO) is a little more friendlier than Ubuntu, but is a direct fork of Ubuntu so you shouldn't have any compatibility issues. First, install git and some dependencies. This assumes GPredict is already installed. *sudo apt-get install git libglib2.0-dev libtool intltool libcurl4-gnutls-dev libgoocanvas-dev* Then you'll want to grab the code. *git clone git://git.code.sf.net/p/gpredict/code http://git.code.sf.net/p/gpredict/code gpredict-code* This will create a new directory (probably gpredict-code); you'll want to move into that directory. *cd gpredict-code * Next, run the autogen script. This prepares the code for installation. *./autogen.sh* Assuming that runs all the way through without exiting for errors, run *./configure* then *make* and finally *sudo make install* Assuming everything goes according to plan, you should be able to launch the program by running */usr/local/bin/gpredict* Make sure it's the correct version by going to Help About GPredict. GPREDICT 1.3.242-b445 is the text you're looking for. Finally, let's replace the out-of-date binary with this one. This probably isn't the best way to do it, but it works. *sudo mv /usr/local/bin/gpredict /usr/bin/* That should do it for updating it to the latest version. Other changes that were helpful: Duplex TRX Sub Up / Main Down in the interfaces prompt Modules Layout Select Layout All Views (Wide) (Requires restart of program) Anyway, good luck. Let me know how it turns out. 73 de KE5GDB On Sat, Jun 21, 2014 at 12:53 PM, Richard Lawn rjl...@gmail.com wrote: Rats! It's been a struggle up to this point.

Rigctld is part of hamlib. I think the command to list all of the different radios supported is rigctl --list. Under the Interface configuration, you must specify your rig capabilities. All this does is tell GPredict what to expect from hamlib/rigctld. rotctld is the one for your rotor. It works in the same manor as rigctld. Let me know if you've got any more questions or need further explanations.

[amsat-bb] K5UTD Is On The Air
Hello Group! After about 6 months of work, I'm proud to say that the K5UTD Amateur Radio Club (University of Texas at Dallas) has finished setting up our satellite station. Typically it should take a weekend and a case of beer to get the job done, but this required a little more planning and involvement as we had to collect the parts from various people and build several components on our own; not to mention the fact that we get side-tracked like no other club. For example, an effort to get the rotor controller resulted in moving about four truckloads worth of gear. We're using an FT-847 for our primary radio, and a Kenpro G-5400 for our rotor system. We've interfaced the G-5400 to the computer using an Arduino. It works rather well with GPredict. The final bug in the system has to do with GPredict talking to the '847, but that should be easily fixed with an update. The antennas are on the roof of our Engineering and Computer Science building, about 20 feet off the roof, 70 feet above ground. Out of luck, we had a GlenMartin RT-936 and the associated non-penetrating mount just hanging out in our closet. Carrying the 50 cinder blocks up to the roof for that mount was not fun though. Coax wise, we have about 20 feet of Davis Bury-flex for our initial run, which then feeds some very nice ARR preamps. The final 200 foot run of coax to the shack is 1/2 Heliax. There are a few jumpers here in the shack too. I was able to make a few contacts through SO-50 today, and plan to be more active. With the help of DK3WN's SatBlog, I've had no trouble picking out some cubesats and listening to the beacons and telemetry. Telemetry collection is one of the primary goals for this station. Our other goals for this station, aside from having fun on the air, are to get club recognition on campus and to work with the William B. Hanson Center for Space Sciences on upper atmospheric projects. Station photos: http://imgur.com/a/6TGOJ Also, if you know a member of the former TI club, give them a hug (or handshake) on our behalf. None of the current K5UTD projects could have been possible without them. 73!

[amsat-bb] Re: K5UTD Is On The Air
Glen, While technically not in Dallas, I will argue that it is partially in Dallas County. See the image linked below. Our antennas are 100 feet from Dallas County, according to Google Earth. The only thing left of TAGER is the TAGER tower, and from what I hear, they want to take it down. It's sad, as the tower is hosting 1 repeater, and might be hosting a second in the near future. Feel free to drop by on our repeater 145.43- 110.9.

Greg, At this point in time, we're entirely grounded to the building's Franklin loop. Although this is probably adequate, it's not quite up to our standards. We don't have any lightning arrestors on our coax (yet), but it's on the shopping list for Ham-Com and Dayton. They're not high, but also not low priority. When we do get some, they'll likely be mounted near our preamp box. 73's de KE5GDB On Thu, Apr 17, 2014 at 9:28 PM, Greg D ko6th.g...@gmail.com wrote: Nice project!

[amsat-bb] Re: satellite durability fm vs. linears
The thing I've been wondering (and this is in no way accusatory, just a question out of curiosity) is why we didn't build the IHU's with NVRAM and a circuit to cut the batteries completely out of the loop. Since the cell failure seems inevitable, it would only make sense to design the satellites in a way that they can work without the batteries when the batteries do fail. In my humble opinion, I think DO-64 was genius. It happened to fail for another reason, but it was an interesting concept. Their telemetry program was pretty neat too.

As far as getting the information updated on these sites with the new satellite, you must remember that they are both volunteer run, and the updates have to fit in the schedule of the volunteers who run the sites. 73 de KE5GDB On Sat, Sep 19, 2009 at 8:42 AM, Ben Jackson b...@innismir.net wrote: http://oscar.dcarr.org? -- Ben Jackson - b...@innismir.net - www.innismir.net Sent from my Mobile Device Andrew Rich wrote: Can we get a web page that shows Sat name Lauch date Active in last 24 hours Frequency / mode.

[amsat-bb] Re: PE1RAH pictures from Ham Fair Tokyo
Do you happen to have any pictures of the Yaesu FTM-350?

I have also seen the new ICOM 9100 at the ICOM booth on the Ham Fair here in Tokyo. The rig looks very nice, but when I asked some technical details they said that they still working on it and that it is not finished yet. The IC9100 on the booth was not RF operational (maybe reason why no mic was connected on it). It still has a nice look, and it would be a great rig to have in the future shack.

[amsat-bb] Re: NASA Kills Ulysses
This whole discussion relates back to Bob's proposed idea of having several Cubesats on standby in the event that we're given a last minute opportunity to launch. I think that'd be the place to start. 73 de KE5GDB On Wed, Jul 1, 2009 at 2:12 PM, Luc Leblanc luclebla...@videotron.cawrote: Hello planners!

OK, so you might win some, might lose some and I know it would be expensive but it seems better than the situation we have now, plus we could be potentially building in some long term birds that would replace the current ageing fleet. It would be a long term view, but it would be something!

[amsat-bb] Full Duplex Radios - A Complete List
After a couple of hours of surfing around on Universal Radio and other radios sites that keep a good archive, I've completed the list of full duplex radios. Use it however you want; print it out before a hamfest, post it in your shack. All that I ask is that you let me know if there are any errors on the list. Full URL: http://thathamkid.com/website/ham-radio/full-duplex-radios Shortend URL: http://bit.ly/JclIa Also, up in the top right-hand corner of the article is a little icon of a printer.

[amsat-bb] Re: SO50 problems and questions
I also forgot to mention that a PreAmp makes all of the difference. I worked a few passes with N5AFV this past weekend for Museum Ship weekend, and he let me borrow his preamp. On AO-27, it went from an S-1 to an S6, and with SO-50 it went from an S-0 (still audible though) to an S-4. I'll also embarrassingly admit that I had my arrow pointed in the wrong direction (for part of the pass), and AO-27 was still audible with an S3, but only with the preamp. I believe we used an AAR SP450VDA. On Tue, Jun 9, 2009 at 11:22 PM, Andrew Koenig ke5...@gmail.com wrote: I would try taking the antenna off of the tripod for a little while. The polarization of the satellites changes constantly, and with the antenna on the tripod, it's difficult to compensate for those changes. Also, AO-51 is a much stronger bird than SO-50, but AO-27 is the strongest at the moment. AO-27 has the same frequencies as SO-50, but there is no tone, and it's got a timer on it that turns it on when it reaches (about) the Gulf Coast line (for the purposes of maintaining battery power). You'll have time to get your antenna in the right place with the 20 seconds of telemetry it starts with (see http://www.ao27.org/AO27/index.shtml for a schedule). For your situation, I would recommend trying AO-27 until you are familiar with the satellites. AO-27 isn't as crowded as AO-51, but it's also not as quiet (both in traffic and output) as SO-50. Don't quote me on it, but I think AO-51 has less than 500mW output right now, AO-27 is 500mW and SO-50 is 250mW. Good luck! Once you get the hang of it, it's easy enoguh that a teenager can do it (I'd know..) 73 de KE5GDB On Tue, Jun 9, 2009 at 9:18 PM, LeRoy Miller kd8...@sprint.blackberry.net wrote: Hello I am relatively new (- I have been tring on my own to get the hang of working the satellites) with little or no luck. I have been posting my failed results to twitter and getting over frustrated in my attempts - luckly there have been a few who have given me pointers. And one very nice person kl7cn let me call him and he talked me though a few things during the call he said maybe I should try the SO50. So today I did try it And much to my surprise and happiness it was easy enough to pickup and find and things seemed to working for me (He told me that is was a quite machine and that I might have to look for it a bit) The pass I tried was at 1710 UTC (110 pm local est) and the sat was moving from the southwest to the northeast from my previous trys on the AO51 I knew that I would probably not get it while it was still low (less then about 20 degrees - also because of where I was pointing the antenna that low I was pointing right at a building) I reasoned that if I started looking at about 24 degrees I would being doing much better (so that is what I did) at about 1714 or 1715 UTC I had heard the SO51 for the first time, still a bit rough and probably still a little low by the time it was up around the 40 degree mark I thought What the heck I am here, people are talking why not try to make a contact - so that is what I did I think I waited just a little longer got a nice strong signal and put my call out KD8BXP em79 -- What I heard on the downlink really surprised me - it was this horrable noise (it almost sounded like when 2 people double) I don't know what I did but thought ok maybe feedback from the microphone so I unpluged the external and tried again I got the same horrable sound Now I am sorry up front for this noise I am sure people heard it - so if you were on around 1717 - 1720 I am so sorry upfront But that leads me to my question - what did I do wrong? And how can I correct the problem and try again I have been really frustrated with the AO51 so much so that I almost put my rig antenna and what not on ebay 3 days ago - I cooled off but I really want to work this bird It seemed (at least to a newbie) an easy one to find and maybe make contacts on. You will need to know the setup: TH-D7 A (not the G model I have a G but didn't use it this time) Arrow (2 meter/440) mounted to a telescope tripod Eeepc running ubuntu linux a gpredict External mic for the radio I was on 145.850 pl 67hz for the uplink And 436.800 for the downlink Radio was in duplex mode and sql was turned off (or open if you prefer) And the balance on the speaker was set for only the 440 side I was at 40 - 50 degrees when I first keyed up and the second time would have been when it was at its highest point of between 64 and 74 degrees I was on the high power setting I have used this radio for both local repeater work and aprs and no one has ever told me that it was making horrable noises And I think if it was making horrable noises while transmitting aprs the data would be corrpted I hope I have given enough information. I hope someone can help I don't want to make horrable noises again One other thing but I am sure it is my problem not one
