LVB Tracker USB serial port driver for Windows 7 x64?

by Bill Bordy, NJ1H

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

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.

FW: Re: The Moon is our Future

by Dave

We have met the enemy and they are us. WE need to do something. Yes, $15m is outta reach, but isn't there a cash prize for the first on-commercial moon landing?

I couldn't agree more - we don't need more of the same. If I want to sit back and have a two hour rag-chew with someone on the other side of the planet I will use Skype or my cell phone! 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? We don't need any more FM repeaters buzzing overhead, but what about more cameras downloading HD images, scientific payloads that monitor the ongoing climate change, payloads to study the Earth's magnetic field, etc. etc. Our own 'Twitter' messaging network from space...? The Apollo 13 creed of "failure is not an option" has completely infected the brains at AMSAT and this list. 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. In the meantime we have to stifle the truth because it might blow yet another *secret* deal that's in the works and *almost* a done deal, so let's not complain publicly and ruin it. Heard the stories, heard the lies, got all the t-shirts and ball caps. Whatever. -- Jeff, KE9V AMSAT-NA member since 1994, Skeptic that we will ever go back to HEO since 2002 _______________________________________________ Sent via AMSAT-BB(a)amsat.org.

AO-7 New distance

by ps8rf Piraja

Hello friends, The new record via AO-7 was established today between Luciano, PY5LF and Joe , K3SZh via AO-7. The distance the new record is 7839 KM. I have a audio record with a portion of the QSO. The log of QSO can be seen on web site http://www.planetemily.com/ao7/ao7log.php . Congratulations to both. 73, Pirajá, PS8RF _________________________________________________________________ ACESSE SEUS EMAILS DE QUALQUER LUGAR PELO SEU CELULAR.

thanks for QSOs during AO27 demo

by Patrick STODDARD

Hi! Thanks for the QSOs during the last AO27 pass. It was nice to hear much of North America on the pass. Even Larry XE2/KI6YAA from another part of this city. I do not know if I will work any of the upcoming AO51 passes, since I need to make my drive home sometime this afternoon or evening. Apparently there has been a lot of rain in my home city Phoenix. Thanks to everyone who made QSOs with XE2/WD9EWK over the past couple of days. 73! Patrick XE2/WD9EWK - Mexicali, Baja California http://www.wd9ewk.net/

AO-51 Status and Mode

by Patrick Farcon

Hello all! I have not been able to work many passes lately due to schedule at work but the last two early morning passes that were very good I have not been able to pick up the satellite at all. Is the satellite not in V/U mode? I was just wondering if others are seeing the same thing. Thanks to all the ground operations team members that keep the satellite in check and to all that I have met on the satellites! It has been a great new facet to the hobby for me! Pat N2VYT FN20un

AO-51 back on

by Andrew Glasbrenner

We are completely reloaded and operational, in about 24 hours. 145.92/435.3 repeater is running with 67 Hz tone required to activate, and will stay on for 2 minutes at a time. Output is 740 mw and subject to change. We may have to adjust some other settings over the next day or two. Please use the webpage at http://oscar.dcarr.org/ to post reports. For some reason very few US stations use this. Please do as it is impossible for us to listen to every pass. 73, Drew KO4MA AMSAT-NA VP Ops

Re: AO27/TS2000

by Edward R. Cole

That may be because the source of the birdie is near the radio and not necessarily coming from the radio (e.g. nearby computers). The FT-847 is famous for its internal birdies, but they are either gone or diminished when I connect my eme antenna with tower-top preamp. Some do not disappear so are probably being radiated from the neighborhood. A good test is to terminate the radio with a dummy load and see what birdies remain (most likely are internally produced in the radio). Then connect the antenna with preamp and see how many go away or are greatly reduced. And see how many new ones show up! a preamp can generate birdies from intermodulation products or self-oscillation. So saying, RF is a messy business. ;-) When I point the 2m eme array at 70-mi distant Anchorage the noise floor rises (slightly). It drops if I swing in azimuth or raise above 10-degrees elevation. In character the noise is not exactly white noise but has a faint line-noise sound. Cities have a lot of lines. ;-) 73, Ed PS: I am going to be interested to observe how many birdies my Elecraft K3+DEMI 144/28 xvtr combo produce compared with the FT-847 on 144 (144-144.030 is unusable due to birdies) At 12:11 PM 7/31/2010, Bruce Robertson wrote: >To improve the birdie issue on the TS-2000, be sure to keep your >antennas well away from the radio.
