LVB Tracker MacDoppler
by Roger Swickis 08 Jun '08

08 Jun '08

I have just received my assembled LVB Tracker box from AMSAT. I would like to control it using my iMac and MacDoppler. I have downloaded the instructions from LVBTracker.com When I turn on the LVBTracker the indicator says I have v0.7, then it says "Warning bad EEPROM data." prior to displaying the az/el data. Should I worry about this or should I simply ignore it? Do I need to install different firmware? I have attempted to calibrate the Trackerbox and have managed it a couple of times, however it doesn't seem to want to retain the azimuth information once I have turned it off and back on again. Any suggestions? (The LVBTracker has both a USB and a DB-9 socket on the back, do I need to open things up and select one or another? ) I have downloaded the FTDIUSBSerialDriver file. It will only install on the main "Macintosh HD" level, and does not allow me to select another location during the installation. I am not familiar with the Mac OS, do the drivers need to be moved to a particular file? The instructions suggest that I "... talk to the LVBTracker using a terminal program ..." Suggesting that I "Setup (via the terminal program) the COM port selected for the FTDI USB device, 9600, N, 8, 1" How do I perform this "setup"? How do I select a COM port via the terminal program on a Mac? (I have done this on a PC for a COM port, but I have no idea how to do it via a USB port on the Mac.) Any suggestions? The instructions say that "All the tracking programs ... have good instructions for setting up a rotor controller." I do not find this to be true for Macdoppler, which has a minimum of instructions. (The LVBTracker instructions mentions "Macdoppler Pro", I only have something called "Macdoppler" do I need to upgrade to Macdoppler Pro?) Under Macdoppler "Preferences", "Rotator", I can select my rotator, and baud rate, but I don't know what serial port I should select. I presume its "usbserial", but it could also be "SerialPort-1", which is also an option. Is "usbserial" the correct serial port to select? (I am controlling my IC-821 somewhat successfully via Macdoppler using "usbserial" and one of the iMac's USB sockets using a CI-V interface cable. I would like to use another USB cable for the rotor control. Do I select "usbserial" for both? (Of course this leaves me a little short of USB sockets, has anyone daisy- chained the radio and rotor control via a single iMac usb jack and one of those multi-usb boxes?) Sorry for all the questions, but I am just about at the stage where I go back to using my old PC and try to get things running using SATPC32 through COM ports, but I would like to control things via the Mac if that is possible. Is there anyone out there who has succeeded in getting the LVBTracker to work via Macdoppler and can help? Thanks, Roger VA7MG

Of the satellites listed (according to the list posted at http://www.amsat.org.uk/iaru/finished.asp), the following satellites have been coordinated with IARU for use of the amateur satellite spectrum: * Swisscube: Space Center, Ecole Polytechnique Fédérale de Laus * Goliat: University of Bucharest * UWE-2 (but not yet UWE-3): University of Wuerzburg Unisat3 from Rome was launched with AO-51, however the UniCubesat is not listed with the IARU. It appears that the IARU Coordination group knows nothing about the other satellites listed in the press release. But then, it also appears that the recent Russian RS-30 "Jubilee" was apparently unknown/uncoordinated. If any of you are in contact with any of these groups, please stress to them the need for coordination with the rest of the amateur radio/amateur satellite community. Information of the coordination process, along with some recommendations (including a very useful link budget spreadsheet from Jan King W3GEY/VK4GEY) can be found at http://www.iaru.org/satellite/. 73, Tom

Hi Domenico , you are absolutely right! the main problem is that young people involved in projects not even know what is an "hamradio" and what is an "ham spirit" (in Italy this is the situation), so whithout these conditions you can't produce something right for our community think only this: the only satellites "ham-useful" have been produced outside university programs I write this because I personally experienced what it means Only AMSAT have the right spirit ( and experience..) to produce useful object when a university has to create a satellite? turns to us... For Italian University satellities is so 73 de Giulio AB2VY Hi David, G0MRF It seem to me that while the Universities are becaming tennis players we collect telemetry without to be involved in their experiments and this is like to only pick up their balls and run with it. The only difference is that each University receive governement contributions to build the satellite while we radioamateurs invest a lot of personal money to build our own satellite stations. Since the Radioamateur Community make a worldwide service to the Universities my idea is to collect their TLM upon official donations to be used to build our Orbiting Satellites Carrying Amateur Radio i.e. satellites with linear transponders to talk each other. Is the Amateur Satellite Service becaming an endangered species ? It will became an endangered species if P3-E and EAGLE will be not placed in orbit as soon as possible but this requires our contributions ............or not ? Do you like my TLM ?............Please donate ! 73" de i8CVS Domenico ----- Original Message ----- From: <G0MRF(a)aol.com> To: <amsat-bb(a)amsat.org> Sent: Saturday, June 07, 2008 4:29 PM Subject: [amsat-bb] 9 Cubesats selected for free ESA ride to space > Cubesats built by students from universities in Poland Spain Italy > Switzerland Romania France and Belgium have been selected for a free ride to low earth > orbit.

Idea
by D. Mynatt 07 Jun '08

07 Jun '08

In the last AMSAT Journal, Dr Shuch addressed the issue of education from the perspective of students and teachers. I would like to add one other idea to an otherwise excellent piece, and that is 'what are the experts doing'? I would like to propose that AMSAT or the education side of the organization, establish teaching centers where students can go for more than just Field Days. I promote an idea of a center where large antenna arrays are installed, accessible via the internet, controllable by schedules appointments, overseen by the AMSAT experts, and acting as established communications centers or ground stations to as many different flights as possible. I'm talking with M2 and ISIS about antennas and such, but wonder what comments and ideas the group would have about the idea. Any other ideas to address the need for new members, new interest, and involved kids?

70cm antenna SWR problem solved?
by Michael Tondee 06 Jun '08

06 Jun '08

After several unsuccessful attempts at solving my 70cm antenna problem while it was still on the mast, I resolved today to just go ahead and get it down off there. Not that big a deal to do really and besides I've been thinking of rebuilding the whole shootin match anyway. I was able to use my 2 meter SWR meter after a fashion once I got the antenna inside. I could see fluctuations in the amount of power the antenna was taking as I tried various things. The problem lies in the area of the matching and feedpoint of the driven element. Again those of you familiar with the WA5VJB " cheap yagi" concept will know that the driven element is bent back upon itself forming a U shaped section on one side. Those less familiar with the design might not understand this but there's something going on right there. Either with the spacing between the legs of the U or the braid and center conductor being too close together at that point where they are soldered. Changing the spacing of the U legs didn't seem to help but spreading the center conductor and shield out from each other right where they are connected to the DE made a marked difference. I suspect it's because at this point they are very close to the "matching area" of the antenna. Hope that makes sense. At any rate I have decided to rebuild both my 70cm and 2 meter antenna. I will keep 11 elements on 70cm but I'm going from 4 to 6 elements on 2 meters. The other change will be to replace the boom material. I used PVC pipe before and the antennas have developed a bit of a sag along their booms. I will be using wooden booms coated with spar varnish this go around and possibly add reinforcement if any sag appears evident. BTW, both of these are linearly polarized as I don't have an SWR analyzer to figure out velocity factor on cable while making phasing harnesses. Maybe someday! Thanks much for everyones help and 73, Michael W4HIJ
