- Forwarded Message - From: "thomas m" To: "thomas m" Sent: Tuesday, May 15, 2012 9:50:59 AM Subject: live ham radio webcast We are 24 hours away from our live dayton hamvention broadcast. Help us spread the word to anyone interested.? This will be our 10 th year to broadcast Dayton Hamvention . Our viewers have grown to about 50,000 in over 150 countries during the last Hamvention broadcast. Hamvention is May 20-22 but we actually go live TOMORROW at 1300 UTC Wed May 16th as we pull out of our driveway and broadcast the 550 mile drive live. The video site is http://w5kub.com and we are on 365 days a year when not broadcasting a live ham event. Over the years we have had special guests on the broadcasts. We have over $8000 in prizes to give out again this year to lucky viewers. Some of our prizes are weather stations, Heil headsets, Comet CAA-500 antenna analyzers, AlphaAmp watt meters, D-star radios, yasue HTs, TenTec desk mics, G5RV antennas, and much more. After hamvention, we will be broadcasting our 550 mile trip back to Memphis on Sunday afternoon. We have installed a new Ka Band internet satellite uplink this year in our fleamarket space so we will be broadcasting High Def video this year. This is a first for us. Log into the chat room and talk directly to us, ask questions to those we are interviewing or just chat with each other. Dayton Hamvention is Fri, Sat, Sun May 18,18,20 we also will broadcast the 550 mile drive (10 Hours) from Memphis, Tn to Dayton Ohio Wednesday may 16 We will be setting up our fleamarket space and the satellite uplink on Thursday May 17 and will broadcast that. We will start giving out prizes on Wed morning. go to http://w5kub.com for all the fun also join us on our facebook broadcast page at https://www.facebook.com/groups/279273778772594/ Thanks, Tom W5KUB ___ Sent via AMSAT-BB@amsat.org.

[amsat-bb] Learning about AMSAT in Dayton
I have been interested in AMSAT operation for awhile but have not even began to put together a station for satellite work. I will be attending the Dayton Hamvention this weekend, and in doing so I am hoping to learn enough about satellite work to get on the air over the next few weeks. With the large collection of AMSAT experts in Dayton, my question is what the group would recommend to a newcomer to try to get out of Dayton in learning some satellite basics. Should I make sure to go to the forum? Are there going to be demonstrations on software and station setup? Should I mainly try to make in-person resource contacts? Mainly, where should I focus my efforts this weekend? I am hoping to learn as much as possible and hope to finally get involved in satellite operations in the next few months.

[amsat-bb] Re: Learning about AMSAT in Dayton
Steve, My recommendation is that you attend at least one of the satellite demos for an FM satellite (AO-27 or SO-50) *and* an analog satellite (AO-7, FO-29, or VO-52). The techniques and contacts are different for FM and SSB; you will learn from both types of contacts. Note that the ISS and HO-68 passes will be listening only, and won't involve 2-way QSOs. Take the time to talk with Keith, Roger and Mark who will be running the demonstrations just outside of the entrance to the Ball Arena. I would also encourage you to attend the AMSAT Forum, but if your primary goal is to learn about assembling a station and operating the sats, the demonstrations are your best starting point. I'd also suggest you buy a copy of Gould's revised Getting Started with Amateur Satellites book. It will be for sale at the AMSAT booth and is a great source of information for those questions you forget to ask at the demos. There will also be demonstrations of SatPC32 and MacDoppler at the AMSAT booth, so you can see how the tracking software works.

[amsat-bb] L band uplink frequencies
Hi all. I am trying to determine an FM uplink frequency in L band which is suitable for most countries. As I understand it, 1269 is the traditional frequency of choice, but with Galileo now being deployed and some local EIRP restrictions here in Europe, that may no longer be the best choice. In searching the AMSAT archive I saw several messages about the P3E 'galileo alternative' at 1260 and a message saying that there is an EIRP limit in Germany below 1263MHz. - Is that still accurate? The final suggestion from those posts was 1263.520 Ultimately some frequency agility to avoid radars etc may be needed, but as with all projects, a starting point is needed. Any thoughts?

[amsat-bb] Re: Learning about AMSAT in Dayton
Amen to this, Steve (both Steves actually ;) ) This year, we have a clear focus on trying to get youth and first time operators ON THE AIR. We want you to come to the microphone and make a contact!!Between passes, there is plenty of time for equipment review, discussions, inspections, etc.The SSB and FM birds are quite different, but once you have the gear up and running, the transition is pretty straight forward. Thanks to Keith and Roger, I understand we'll have differing levels of equipment again (from very portable/simple, to stuff more complex resembling a fixed station with computer control of radio, etc.) So check it out! Come out and get your feet wet (well, figuratively. We are hoping for no rain :0 ) Bring the kids...or grab some on the way...hi hi. See you later this week! 73, Mark N8MH AMSAT VP Educational Relations On Tue, May 15, 2012 at 12:23 PM, Stephen E.

[amsat-bb] Re: Learning about AMSAT in Dayton
Steve, The answer to your questions is YES. For starting out, as Drew suggested, see as many passes worked in the demo area as you can. Likewise, at the AMSAT booth you can pick up some good intro books, and talk about software, hardware, etc with experienced operators. If everybody seems too busy to talk, swing back around in a few minutes. The Forum is oriented toward "big picture" issues rather than operational nuts and volts. You can get an idea how things are now, and how they will be different in a few years. 73s, Alan WA4SCA -Original Message- From: amsat-bb-boun...@amsat.org [mailto:amsat-bb-boun...@amsat.org] On Behalf Of Steve May Sent: Tuesday, May 15, 2012 9:30 AM To: AMSAT-BB@amsat.org Subject: [amsat-bb] Learning about AMSAT in Dayton I have been interested in AMSAT operation for awhile but have not even began to put together a station for satellite work.

[amsat-bb] Harbor Freight Items
Two items on the Harbor freight weekly newspaper ad jumped out at me today ... The first is one of those "jump starter" batteries in a plastic case with handle, jumper cables, meter, et al. This one is probably a 10-12AH sealed lead acid one. Its case is not "sonic welded" - so we can get inside and "improve" the panel with whatever jacks we want (grin). Here's the instruction manual for more description - $33.99 this week ... http://manuals.harborfreight.com/manuals/38000-38999/38391.pdf The second item is a "mechanic's roller seat." I can see my 12V marine battery on its bottom platform ... a mounted radio or two on the top (might replace that "padded seat" with a simple piece of shelving), and have a "rolling" cart for a portable setup. On sale for $17.99 this week. http://www.harborfreight.com/mechanics-roller-seat-3338.html Clint K6LCS -- Clint Bradford, K6LCS http://www.clintbradford.com ___ Sent via AMSAT-BB@amsat.org.

[amsat-bb] Satellite Solar Power (indoors)
You would be amazed at how little power a solar panel gets in the classroom or the lab. I measure it. It is one half of one percent of full sun (0.5%). Practically nothing. Here are two examples: 1) We have a flight unit of the original TRANSIT satellite in our sun lit wall-of-glass lobby. It has about 8000 1 inch square solar cells. We built a small "packet" link and a small SSTV camera so we could command it and watch when refreshments were being served in the lobby. Even with all those solar cells, and full indoor lighting and indirect window lighting, the power available is only about 0.1 watt. We had to back off and only have it come on when there was full sun on the arrays in the late afternoon, all the other time there was no power to run it. Even with the eight 1'x6'solar panels. 2) Laugh at this one and BUYER BEWARE! check out www.solaroadtechnologies.com. They claim "Their products are undoubtedly the best solar/storage products available." They are located in Towson, Maryland. And complete hogwash. They sell you solar panels for your desk and your cubical to collect free energy from the office lighting. Yes, not even enough to light a single LED. 0.5% of outdoor sun is nothing. Modern day adage: Just because there is light, and just because it spins, does not mean there is any useful power! Bob, WB4APR ___ Sent via AMSAT-BB@amsat.org.

[amsat-bb] CubeSats defend Planes
Amazing how the press present things.

[amsat-bb] Re: Satellite Solar Power (indoors)
This is precisely why the WA8SME CubeSat simulators run off alkaline batteries! Not enough light in a room to keep the batteries charged all day...

[amsat-bb] SatPC32 Add-On
Here is a video demonstrating a feature I hoped to turn into a SatPC32 Add-On. It is actually quite interesting and I think it would be quite useful when giving demos. The video is HD and looks best viewed full screen in 720p. http://www.youtube.com/watch?v=g1K1sIw_F8Y 73 W9KE tom ... ___ Sent via AMSAT-BB@amsat.org. Opinions expressed are those of the author.

[amsat-bb] Kindle pass predictions
Hi Gang, Has anyone been successful getting the AMSAT predictions on their Kindle? Mine may be one of the first and as such the inner workings may be too "experimental" but i do get some really funky results- the pass page comes up, looks genuine, but a lot of the data is really off the wall- like the times are from some grid on Mars or ?? W2RS was apparently successful but don't know if his is a later version of the Kindle Any help anyone Thanks in advance Dave WA6EKR E-mail JHBRTOO @AOL.COM ___ Sent via AMSAT-BB@amsat.org.
