WD9EWK @ Tucson AZ hamfest...
by Patrick STODDARD (WD9EWK/VA7EWK) 04 Apr '09

Hello! I am at the hamfest in Tucson AZ, and realized I forgot to mention where I will be lurking on VO-52. Look for me on the downlink around 145.910-145.915 MHz USB. I like to be a little higher in the passband, as not to bother those who are closer to the center of it. I have a very shallow VO-52 pass at 1553-1601 UTC, with maximum elevation of 7 degrees. The following pass at 1727-1740 UTC is much better for me, with maximum elevation of 71 degrees. 73 from Tucson! Patrick WD9EWK/VA7EWK http://www.wd9ewk.net/

WD9EWK from DM52 and DM53 tomorrow afternoon/evening
by Patrick STODDARD (WD9EWK/VA7EWK) 04 Apr '09

04 Apr '09

Hello! I'm in Tucson AZ tonight, in advance of tomorrow morning's hamfest. I will not have to hurry back to Phoenix after the hamfest, so I'm going to make a nice drive home after the hamfest - 300 miles/500km! I am planning to head toward grid DM53 in eastern Arizona. I am confident I will be out in that area for two AO-51 passes tomorrow evening (0055-0109 and 0236-0247 UTC), possibly parking on the line between grids DM52 and DM53. Since it will probably be a 2-hour non-stop drive from Tucson to reach DM53, and at least an hour to get to a place in DM52 where I can stop and operate, it is possible that the first AO-27 pass I have at 2030 UTC will be from DM42 (the same grid as the hamfest). I am not sure I can make it to DM53 for any of the AO-27 or SO-50 passes during the afternoon, but should be in DM52 for some of those passes. Although I am traveling with my little laptop, I have already printed the pass predictions for the FM satellites and VO-52 for the day. I also have made notes to know where on my drive I will be in DM52 and then DM53, so I don't need to run a mapping program on the laptop or rely on a GPS map while driving. For all of my Saturday activity - at the hamfest in Tucson, and on the road in the afternoon/evening - I will be happy to QSL these contacts. Just e-mail me directly with the pertinent details for our QSO(s), and I'll get a card out to you. If I haven't sent out my cards from other demonstrations and activity in the last few weeks, I can add any cards from tomorrow to the envelope heading your way. 73!

Implementation of Slow Scan TV on a Weather Balloon.
by Nathaniel Bonton 03 Apr '09

03 Apr '09

Hello AMSAT Community, I am Nathaniel Bonton, the Sensor's subsystem leader for the Balloon III project. This is a project of the C.A.P.E (Cajun Advanced Picosatellite Experiment) organization located at the University of Louisiana at Lafayette. The Balloon III project is designing, programming and launching of a weather balloon to be released from the Lake Charles, La weather station. There are many different implementations such as: temperature sensors, slow scan TV, etc. This brings me to the purpose of this post. I would like to ask anyone if they know of any one that was able to implement a slow scan TV on a weather balloon and if it is even feasible. Thank you for your help and input.

Satellite frequency assignment
by Kelby Davis 03 Apr '09

03 Apr '09

How are frequencies chosen or assigned for new amateur satellites? Is there a coordinating committee or some guide line? I'm interested in the vhf uplink and uhf downlink.

off topic: space station of another kind
by Bill Booth 03 Apr '09

03 Apr '09

Sorry to be off topic a bit maybe (we are all space fans one way or another) but I am wanting to help a friend ..... The small town of Vulcan Alberta here in Canada is working to get the first screening of the new soon to be released Startrek movie in Vulcan. There is a lot of movie and professional people behind this cause, being led by Dana Dickens, the Vulcan Tourism Director. This group was created as part of a campaign to bring the World Premiere (or even a sneak peak) of the new Star Trek movie to Vulcan, Alberta (population 1,942) in May 2009. At least check out the web site below to see how dedicated this town is to Bulcan and the Star Trek concept. To play an active part in this process you can use facebook to check out the group and its process to date. The Facebook location is: "Star Trek XI - Help bring Spock home to Vulcan, Alberta" The Vulcan town site is: http://www.vulcantourism.com If you can help in anyway or would like to add your support, I am sure that Dana would appreciate the input. Again sorry for the off topic ..... but in our hearts we are all Trekies.....

Greetings. Has anyone used the AEA ST-1 with SatPc32 and if so which of the listed rotor drivers did you use, or is there a separated driver that has to be used. I am looking at upgrading my system from DOS to windows 98SE that I have on a spare lap top. Thanks for any help. Dave VA7DG
