LVB Tracker USB serial port driver for Windows 7 x64?
by Bill Bordy, NJ1H 22 Dec '16

22 Dec '16

Has anyone located a driver for the LVB Tracker internal USB to serial port adapter on Windows 7 x64? If not, has anyone reverted to the serial port connection on LVB Tracker and used an external USB to serial port adapter successfully with SatPC32 on Windows 7 x64? I have an Edgeport multiple USB to serial port that has drivers for Windows 7 x64 that I will use if I have to. I would prefer using the LVB Tracker with its USB to serial adapter if someone has another solution. 73, Bill NJ1H

Re: EggBeater
by Bill Dzurilla 30 May '12

30 May '12

Steve, I have both a commercial and a homebrew Eggbeater and am disappointed with both, especially in light of its rather high price. Connected to my IC-7000 via an ARR mast-mounted preamp, performance is far less than with an HT and an Arrow. Guess an omni can't cut it, at least not from my QTH. Maybe if I could get it up higher, clear of all roofs, it would do better. I can make contacts at relatively high sat elevations, but can do just as well with a $10 dual band ground plane. My friend has an Eggbeater and the same preamp at a clearer QTH, and he hears substantially better, down to 10 degrees elevation in some directions. Good luck and 73, Bill NZ5N > > Hi Steve, > > > > It is surprising to read that you are not hearing > anything.

Dreaming about what *might* be in space is a fun exercise. Actually doing something about it requires sending things to LEO because reality has dictated that's as far as we can afford to go. How's about we use some of that frustrated *imagineering* to come up with interesting new concepts at LEO?

You want something at HEO or on the moon, cut a check for $15 million dollars and let's get on with it. Been waiting since 1996 for another AO-13 and I am getting too old to keep waiting. AMSAT is becoming completely irrelevant as it strives without success for the impossible mission and exhibits a shocking amount of leadership malfesance as it stubbornly refuses to recognize and adapt to realities in the launch business. I know, I know maybe NEXT year someone rich will die and leave us a boatload of cash. Or the bankrupt US government will suddenly cough up a billion dollars for some orbiting emergency communication system.

Nanosatellite Launch Service 6 on PSLV-C15
by Daniel Kekez 12 Jul '10

12 Jul '10

Hi All, The Space Flight Laboratory (SFL) at the University of Toronto Institute for Aerospace Studies (UTIAS) would like to announce the delivery of Nanosatellite Launch Service 6 (NLS-6) cluster payload to Satish Dhawan Space Centre in Sriharikota (SDSC-SHAR), Andhra Pradesh, India, for launch on board PSLV-C15. PSLV-C15 will be launching from the First Launch Pad at SDSC-SHAR into 637 km sun-synchronous orbit with 10:30 Local-Time of Descending Node. NLS-6 shares this launch with Cartosat-2B primary, Alsat-2A co-primary, and STUDSAT auxiliary payload. NLS-6 is the 6th launch by SFL. The NLS-6 cluster comprises of two nanosatellite: AISSat-1 and TIsat-1. NLS-6 launch updates are being posted to http://www.utias-sfl.net/NLS-6/ About AISSat-1 ------------------------------ AISSat-1 is built by SFL for the Norwegian Defence Research Establishment (FFI). It is intended to demonstrate a new maritime AIS receiver that has been developed by FFI. The AIS receiver will be used to monitor ship traffic in Norwegian waters. The design of AISSat-1 is based on SFL Generic Nanosatellite Bus (GNB). The spacecraft has a main structure measuring 20 cm by 20 cm by 20 cm and it is stabilized in three-axes using reaction wheels. It has a fixed 46 cm long VHF payload monopole antenna for the AIS receiver and four UHF uplink monopole antennas for the command receiver. The downlink in the S-Band. AISSat-1 has an overall dimension of 80 cm by 45 cm by 37 cm and an overall mass of 6.5 kg. AISSat-1 will be secured to the launch vehicle using the XPOD GNB separation system. AISSat-1 is not an amateur satellite and, as such, has coordinated appropriate frequencies. Its ground segment is located at Svalbard and its control centre is at FFI, near Oslo, Norway. More information on the spacecraft can be found at http://www.utias-sfl.net/nanosatellites/AISSat-1/ and http://www.spacecentre.no/?module=Articles;action=Article.publicShow;ID=513… About TIsat-1 ------------------------------ TIsat-1 is a 1 kg CubeSat of 10 cm by 10 cm by 10 cm and is built by students and staff at University of Applied Sciences of Southern Switzerland (SUPSI). The primary mission objective is to involve students in systems engineering, development and test with a very challenging project and to provide students and staff at SUPSI with space mission knowledge. TIsat-1 will monitor the durability of material probes exposed to space environment, will test a micro electromechanical device and will validate the redundant, fault tolerant hardware and firmware design of the bus. Two monopole antennas (VHF and UHF) will be deployed after separation. Housekeeping and payload data will be communicated to the ground as orbital data profiles. TIsat-1 will be secured to the launch vehicle using the XPOD Single separation system. TIsat-1 communicates over amateur radio frequencies, as coordinated through the IARU, and they have been working with radio amateurs in Switzerland during the spacecraft's development. They have a Morse Code and data beacons. More information can be found at http://www.spacelab.dti.supsi.ch/tiSat1.html Future Launches by SFL ------------------------------ SFL has signed its 7th launch contract with ANTRIX for NLS-7 in late 2010/early 2011. NLS-7 will launch the twin-satellite CanX-4 and CanX-5 formation flying mission. SFL will be signing its 8th launch contract for NLS-8 momentarily, for the launch of two astronomy nanosatellites: BRITE-Austria (CanX-3A) and UniBRITE (CanX-3B). NLS-8 will also launch one partner spacecraft. In addition, SFL is under discussion for NLS-9, NLS-10, and NLS-11 launches in 2011/2012 time frame, and would like to extend an invitation to spacecraft developers world-wide to join our launches.

AO-7 is not OK
by ps8rf Piraja 28 May '10

28 May '10

Some days we are seeing very strange behavior in the AO-7. In some orbits can only hear the feedback on the downlink when the satellite is approaching my station at about 30 degrees elevation, before is impossible to hear any signal via AO-7. Using two pre-amplifier, one in the TS 2000x and the other with 0.6 noise with 20 dB gain. During the orbits we transmiting power with of 30 watts. The satellite does not respond. Tried with 15 watts It was then that we hear at certain points on the downlink audio too low. Its best performance is when the satellite is almost 90 degrees from my station. Yet it seems that the satellite is asking for help. This seems the batteries are not getting enough loads. Or maybe it's excessive use of power by the users of the satellite. Maybe it's time for the users of AO-7 rethink the best ways to keep QSO through it, such as the use of LOW POWER so that over time the satellite is stabilized. "Long live the AO-7" 73' Piraja, PS8RF The Amateur Radio is supportive and helpful in any circumstance. _________________________________________________________________ Você sabia que seu navegador te ajuda a ficar longe de vírus?

Hitting a southbound Moon
by Greg D. 13 May '10

13 May '10

Hi folks, Now that the Arecibo event is behind us, there is still one puzzle that I'd like someone to explain to me. How do I aim at the Moon? I'm on the US West Coast. Early in the pass on Saturday, both Predict and Orbitron told me that the Moon's azimuth from here should be slightly north of east. It was in the 80-ish degree range, with east, of course, being 90. But looking at Orbitron's map display, the Moon was clearly south of my latitude. As the pass progressed, the Moon moved westward on the map, making a sharper angle to the south of east from here. Both Predict and Orbitron's Az calculation increased too (eventually crossing 90 degrees), but always seemed to be north of where the Moon was. Why would I aim north to hit a southbound Moon?

3 passes from DM52/DM53 this afternoon...
by Patrick STODDARD 30 Apr '10

30 Apr '10

Hi! I am at DM52/DM53, waiting for AO27 in a few minutes. It looks like I may have a couple of minutes on the AO51 pass at 2214 UTC that I can work. Around 2217 to 2220 should be the highest part of the pass from here, and I will stick around here for that pass - after the next two AO27 passes. For the east, the 2003 UTC AO27 pass will be the better option, if you have a choice between that and the AO51 pass. 73! Patrick WD9EWK/VA7EWK - near Fort Thomas AZ http://www.wd9ewk.net/

Re: usb to serial adapter woes
by Larry Gerhardstein 30 Apr '10

30 Apr '10

Jim, et. al., Thanks for the advice. However, after installing the USA-49WG and driver install for Windows 7 with help from Tripp Lite technical support, my system still does the same thing. I plug the serial cables to both rotor and transceiver digital interfaces and then to the 49WG and the same thing happens. Azimuth meter drops to zero and there is no control. Further it is now working worse than before, as I have neither control of rotor or transceiver. If measure the voltage between metal shields of the two cables, there is about 2 volts there. It sure looks like a ground loop, but where and how. I have no idea at this point. In 56 years a ham operator, I've never run into anything like this. Maybe RS232 isolators would fix this??? Seems like overkill.

KPC-9612+ with TS-2000
by Nathaniel S. Parsons 30 Apr '10

30 Apr '10

Hi everyone, Thanks for the help with our 4800 bps issue. We haven't found a solution yet, but we're working on it, and I'll let you know when we have something figured out. Just now, I found a Kantronics KPC-9612+ lying around the lab, and would like to fire it up with our TS-2000 to see if it's still in working order. Can someone check to see if I've figured out the pinout correctly? I'll put the KPC pins on the left, and the TS-2000 pins on the right. 1 (Audio out) - 11 (Mic in) 2 (Carrier detect) - 5,7 (Main/sub squelch) 3 (PTT) - 9 (PTT) 4 (CTRLB) - Not connected 5 (RXA) - 1,3 (Main/sub out) 6 (GND) - Any of 4,8,12 (GND) 7 (Ext-In) - Not connected 8 (CTRLA) - Not connected 9 (GND) - Any of 4,8,12 (GND) TS-2000 pins not connected: 2,6,10,13 Thanks, Nate KC2SVI

Re: Space Debris:
by Stephen Melachrinos 30 Apr '10

30 Apr '10

Greg - I didn't see anyone else reply, so I'll try. No, it's not coincidence. After the Iridium collision last year, the US Air Force decided it was in everyone's best interest for them to run conjunction analyses against many more space objects than they had previously analyzed, and report their predictions to system owners. Previously, their concern was primarily the US government's spacecraft, so we (in the amateur community) and many commercial operators never knew what was happening to our birds unless we did (or paid for) the work ourselves. But the collision (as well as the Chinese ASAT demonstration) showed that the resulting debris fields were a major hazard to everyone, themselves included. So they must have allocated more resources to the problem, as this is a massive undertaking. (Note that some reports say that the US has about 20,000 objects that are tracked and cataloged. In theory, this means propagating the ephemeris of all of these for some number of days and comparing all possible combinations across the time period of the analysis.) Unfortunately, many (if not most) of the objects no longer have maneuvering capability. If a vehicle can maneuver, these warnings give them time to try and increase the separation prior to the predicted close approach. (You might have heard of some times when a space shuttle does one of these maneuvers.) But if you can't maneuver (as is the case with AO-51), all we can do is watch and wait.

We built asw weapons (i.e. sonobuoys) in an old brick three story factory with a flat roof. They test dropped the buoys over the side of the building 30-feet into a large vat of water, but the roof was the antenna test range. There I ran tests on VHF antennas. Not a very sophisticated range but definitely "hands on", real RF, real measurements. An engineers calculator was a slide rule, no computers then; fancy computer simulation was unknown. Mostly, I did troubleshooting of the engineering prototypes and finding fixes. Those went back to the engineers to fine tune their design. I quit that and returned to college in summer 1968 and landed a job with Hughes Aircraft in CA. 1971 found me working at Goldstone at the Microwave Test Facility also known as the "antenna range".

Rooftop Antenna Labs?
by Robert Bruninga 29 Apr '10

29 Apr '10

Anyone at a University with an excellent Antenna Lab? When I went through PG school 39 years ago, I was IMPRESSED with the Antenna lab on the roof of Spanagel Hall at NPS in Monterey California and have envied it ever since. I may have an opportunity to begin planning for a major building upgrade at my school and want to propose a modern root-top antenna lab. But my experience is 39 years old, and even then there was a hint (in 1971) that the end of HF was around the corner and so that antenna lab was already in decline... Maybe all antennas labs have atrophed to the internet and have completely abandoned real-live-RF antennas, and so using them as an examples might be a negative example instead of a positive one. But in either case, I need to get some infor for planning a dream antenna lab... Even though Ill probably be 6' under by the time it comes to pass. Hummh... A ham license lasts 10 years... I wonder if one could design a a 10 year micro-beacon for one's headstone that would last exactly 10 years from the time of one's last renewal... Keep the range to 100 feet within the cemetery and not many bodies around you would complain.. Though I guess if there is another ham planted nearby, he would find something to complain about the issue of timely control..Probably best to use a key chain license free XMTR I guess...

Very good to hear Unitec -1 is on schedule. I have built a downconverter for 5840 MHz to 1284 or 145MHz and would like to track the satellite on the early part of it voyage to Venus. - Probably only the very early part of the trip with a 1m dish. However, having read the available information there are still a list of problems that need to be resolved. I wonder if the Unitec team, or the group may have an opinion on the following. 1) What polarisation is transmitted from the patches. Linear? Circular? etc. I need to select a dish feed. 2) How long will Unitec -1 spend commissioning in LEO ? 3) Is there a tracking utility that can show doppler or even direction for a specific geographic location. Doppler is 'interesting' given that you have the probe travelling away from Earth, the Earth orbiting the sun and you also have the movement due to the rotation of the Earth? 4) Given the transmissions on 5840 are 30 mins in a 2 hour period, will there be an on-line counter predicting when the spacecraft should be in transmission mode. (Or a reference time so we can count ourselves?) 5) At what point in the mission will the transmitter be changed from 145 to 5840MHz. 6) Is there a method of sending telemetry to the team at Tokyo? I like a challenge..... Many thanks David G0MRF

Galaxis Space Scanner ACU
by Joe Leikhim 28 Apr '10

28 Apr '10

I have found a number of the model Galaxis Space Scanner ACU Labeled as being made by FutureTrak Intl, and having Lockheed-Martin manufacturer labels. These were apparently made for tracking DBS satellites from yachts and RV's. I saw a post a while back about a website on using these for Ham Sats. Does such information still exist? -- Joe Leikhim Leikhim and Associates Communications Consultants Oviedo, Florida www.Leikhim.com JLeikhim(a)Leikhim.com 407-982-0446

AO-51 mode L/U
by Luc Leblanc 28 Apr '10

Since the new L/U schedule very few operators has been heard on this mode. The first day N8MH give his call sign and about 4 or 5 users are operating when i have the sat in view. It seems the uplink is much more critical than the past L band uplink sessions. it look like the receiver bandwidth was reduce making frequency adjustment more critical. I know the audio level is reduce to save energy but it could explain why many seems to find it is harder to get on the right uplink frequency?
