[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.

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 wrote: > I would try taking the antenna off of the tripod for a little while.

[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.

[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. It's typically used by K5UTD club members and a few TI guys. http://i.imgur.com/imcazFj.jpg On Thu, Apr 17, 2014 at 8:39 PM, Glen Zook wrote: > I just hope their signals are clean! :>) Just joking! > > UTD, actually UTDIRICC (University of Texas, at Dallas, in Richardson, in > Collin County) is located about 1-mile, straight west, of my house. > > UTD is NOT located in Dallas!

[amsat-bb] Re: K5UTD Is On The Air
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 wrote: > Nice project! > > Just curious, what did you do for lightning protection? > > Greg KO6TH > > > Andrew Koenig wrote: > >> 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.

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 wrote: > Rats! It's been a struggle up to this point. Maybe I should wait for it to > hit the repository.
