[amsat-bb] Cub Scout Space Camp Theme
Rich, Good question with a bazillion answers. It all depends on what the venue will be. Small groups, large groups, are they looking for introductory material or something in depth, will the timing be during a pass, what do you want to accomplish.lots of things impact what will be presented. I'd suggest you look into presenting something that matches a requirement to satisfy an award the scouts can walk away with. Perhaps a requirement for a Bear Arrow Point Award. I saw major categories for: Space Weather Radio Electricity Maps Each category has some requirements that could be addressed during your presentation. In my mind, setting up to take a NOAA satellite pass might fit into a number of these categories (of course it all depends on when the scouts will be in the area). This would give you connections to all the categories listed above. You might have the scouts make a model of a CubeSat and then witness a FunCube pass so they can see the data (graphs) that are the outcome of the telemetry (interpreting the graphs would be pretty heady stuff of a scout camp venue). In any event, you're going to have your hands full between the venue, age, time limitation and the bell schedule of the event. If all the stars align and there is an appropriate pass, all it will take is for the previous presentation to run over, and all your careful planning is out the window. So a backup plan is in order. BE PREPARED I guess is the word of the day. Hope you have a busy time. Mark The K4AMG Club has been approached by a CUB SCOUT summer camp coordinator. The camp will be held in Norfolk, VA at an Elk's Lodge on Friday June 27th. Age range of kids are 6 -10 years old. Looking for suggestions of what to do. They are willing to give us 1 - 2 Hours. Example: Toss the satellite where kids stand in a circle and spin a 4 square box around to show orbit and spin. So now it is time for your ideas. Would like to have your responses in the next 5 days ... what should these kids now ... what can they learn!

[amsat-bb] Re: Antenna Question
Hi Doug, I doubt that I have greater understanding of antennas than you do, but I'll give your question a shot. Actually, I have been working on circularly polarizing the ARROWS with the WRAPS lately, a work still in progress but almost complete. So I am throwing out the draft information I have been working on to date. You can circularly polarize a pair of ARROWs and they actually work well together from my experience (one of the reasons I suspect is that the feed system of the individual antennas is very well matched). If you are mounting the two antennas virtually on the same boom (sticking them right next to each other) it might get pretty crowded and interactions complicated. I have mounted two ARROWs separated horizontally about 3 feet apart with pretty good success. I have done this with stock ARROWs, and also with one side with the two meter elements, and the other side with the 70 CM elements (had to drill extra holes for the 70 CM mod), both ways worked about the same. The tricky part is coming up with the right feed lines (the transformer lines and the phasing line). I have a first draft of an article I am working on that describes my latest effort to come up with a polarity switching arrangement for ARROWs with the WRAPS, it can be downloaded here (if you have download issues, let me know and I'll try and get it to you another way). Click here to view Circling the WRAPS https://www.dropbox.com/l/xvKKUtfwUN5gFhGyCiXjua? I will be adding to the conclusion of the piece some suggestions on where to include an external diplexer in the line to handle the single feed line issue that you mention in your post. Anyway, I hope this will stimulate some ideas. Mark Mark Spencer, WA8SME 860-381-5335 mspen...@arrl.org ___ Sent via AMSAT-BB@amsat.org. Opinions expressed are those of the author.

[amsat-bb] FUNcube telemetry performance?
Phil, I have been monitoring the FC telemetry pretty closely and have some observations for what it is worth: 1.The last update to the Dashboard produced marked improvement in decoding the telemetry. 2.Using an IC910, M^2 14-element RHCP yagi with antenna mounted preamp, I typically decode around 120 frames and lose around 10 frames. 3.Using the FCD with a simple turn-style RHCP with antenna mounted preamp, I will get approximately one third the performance of the main station setup. Using a simple antenna with no preamp I get dismal performance with the FCD. 4.Of course I have more success decoding the telemetry when the bird is in the daylight mode than when operating in the night/transponder mode. 5.I have not noticed any significant fading of the signal with the M^2 setup except some minor fading at AOS/LOS. I will get fading using the turn-style however the fades appear to be due to the nulls in that antenna pattern more than due to fades from the satellite. However, the reduced signal strength helps to emphasize the fades with the turn-style. 6.I estimate that it takes a minimum of 50 decoded frames to capture a full set of whole orbit data. It requires a significant number of additional frames to capture usable high resolution data during a pass (I define a usable data set as being able to determine the rotation rate of the satellite from the high resolution data). 7.There is significant frequency drift in the downlink frequency that tracks the temperature of the satellite internals. I also notice significant FMing of the downlink frequency when the transponder is being used (appears to track with the power used by the transponder). The Dashboard does a pretty good job of compensating for these frequency deviations, I haven't noticed any significant loss of data due to this FMing. The frequency drifting needs some attention when using a traditional rig under computer control (the drift is beyond Doppler). When using the FCD, the Dashboard takes care of the temperature drift issue. One of the many interesting things that I am monitoring on this bird is the rotation rate. The bird started out with a rotation rate of .4 RPM, then something happened on or about December 28th and the rotation abruptly started to slow down to a minimum rate of .12 RPM (or 8.5 minutes per revolution) around the end of January, then it started to spool up again to a maximum rate of 1.16 RPM around the end of March, and then it started slowing down again.today at .65 RPM (1.54 minutes per revolution) with the curve trending down. I have taken many mind trips trying to rationalize what I am observing.but all those roads are leading somewhere near Albuquerque and I have no reason to go there (nice place though hihi). Let me know off line if you would like the graphics of my rotation study. Mark Spencer, WA8SME mspen...@arrl.org ___ Sent via AMSAT-BB@amsat.org. Opinions expressed are those of the author.

Scott, I too have just started playing with the NooElec SDR. One thing that hit me between the eyes is that the SDR is not very sensitive. I have had moderate success copying local two meter traffic and APRS signals on 144.390 by using a broad band preamp at the radio and also one at the antenna, with that arrangement the SDR hears much better. 73, Mark Mark Spencer, WA8SME Education and Technology Program Director ARRL, the national association for Amateur RadioTM 43 Pinelock Dr. Gales Ferry, CT 06335 860-381-5335 860-460-1139 (cell) mspen...@arrl.org ___ Sent via AMSAT-BB@amsat.org.

[amsat-bb] FT-817 Sat-CAT Interface Boards and Kits
Hi All, A while back, an article about a FT-817 Satellite Control Interface was published in QST. There were numerous requests for boards and kits on the project. There is a small quantity of the boards and kits available but the procurement information didn't make it in the original article. The raw boards are available for $20, and a kit with the board, parts and programmed PIC is available for $35. You can send an email to Debra Johnson at ARRL HQ and order them from her (djohn...@arrl.org). The proceeds from this effort is going back to AMSAT and the Fox birds, so anything above and beyond these amounts (which are basically at cost) will go into space as part of Fox. Questions?

[amsat-bb] MAREA a School Activity You Can Do
Dinner conversation the other evening. Dad: Suzie, what did you do in school today? Science class was pretty cool today. We have been teaching our robot, Robbie, to move through a maze.last week my group was the first to make it through the maze without hitting the sides. So today, Ms. Smith allowed us to send the commands we made up to move Robbie through the maze up to the International Space Station and back down to Robbie. We used ham radio to do it. I got to push the computer key that actually send the commands! There was some raspy sounds from the radio speaker, a delay, like a hundred hours.well it seemed like a long time. and then Robbie started to go through the maze! Wow, that's pretty amazing. Yes it is. We listen for radio signals from the ISS all the time, but this is the first time that we ever sent our own radio signal to the ISS from the radio in our classroom. And I know that our radio waves were heard in space because the signals came right back down to Robbie and we watched him move through the maze.just like Mission Control does to make Curiosity move on Mars. Dad: Well I didn't know you were an astronaut. Ah Dad, not yet, but I will be some day. .I'm sure you will Suzie. Interested how you can help your school do this? Ask me, mspen...@arrl.org.

Since this discussion started around the topic of the 700 ballots AMSAT-NA received for the Board election, let me add one point to that thought. Thanks to those who voted in the election, whether or not you voted for me. Thanks for taking the time to consider each person who was on the ballot, and for selecting the person or persons you voted for. Amsat is living in a brave new world where launches are fully commercialized and nobody gets a free ride anymore. We will either adapt to that paradigm shift or we will cease to exist. This is the point some want to overlook. It is unfortunate that we are not able to get the free or extremely cheap launches that we had in the past. When there are more satellites to be launched than launches, the launch providers set the prices. Other than some opportunities like AMSAT has for Fox-1 from NASA, the days of free launches are pretty much a thing of the past. So we adapt to the new reality. ___ Sent via AMSAT-BB@amsat.org.

So these bands will be sacrificed to pay for the reallocation of the spectrum that was previously cleared by TV Broadcasters for acution in the name of Homeland Security. The 450 band contains Broadcasting Remote Pickup and Studio to Transmitter links along with other coordinated use. 420 to 450 is our 70cm amateur band. -- *Spectrum Management Bill Threatens Amateur Frequencies* *On February 10, Representative Peter King (R-NY-3), Chairman of the House Homeland Security Committee, introduced HR 607, the **Broadband for First Responders Act of 2011**. The bill been referred to the House Energy and Commerce Committee, which handles telecommunications legislation. * *HR 607 addresses certain spectrum management issues, including the creation and maintenance of a nationwide Public Safety broadband network. As part of that network, the bill provides for the allocation of the so-called D-Block of spectrum in the 700 MHz range for Public Safety use.* *The D-Block consists of two, 5 megahertz-wide segments of **spectrum (758-763 and 788-793 MHz) that became available when the FCC ended analog television broadcasts in June 2009 and reallocated the 698-806 MHz band for Public Safety and commercial broadband.

In my oppinion, I don't see much difference between the military broadcasting on this satellite to hams and cross band HF contacts with military stations where the military transmits on their own frequencies knowing that hams are listening. Granted in some places it may not be legal to listen to 149.985 or for hams to listen to non amateur broacasts but that is another issue. If only the military can uplink to this satellite then I would expect that they are accountable for what gets broadcast. - Original Message From: George Henry ka3...@att.net To: amsat bb amsat-bb@amsat.org Sent: Fri, August 27, 2010 4:28:02 PM Subject: [amsat-bb] Re: New Satellite Downlink? Question: since there is no amateur radio allocation at 149.985, we (hams) would be asking the Navy, to whom the downlink frequency is allocated, to transmit one-way amateur communications thru this satellite, correct? Doesn't anyone else see potential legal problems involved here?

Possible new AMSAT Application? We may have access to two old TRANSIT navigation satellites with a 50 baud downlink at 149.985 (and 400 MHz). (presently coming over in the mid afternoon). My problem is, coming up with any meaningful application to use them for communications that would capture the interest of students, hams or volunteers in support of education, public service or emergency comms or just plain fun... The downlink can be heard on an OMNI antenna (though I would suggest a 3/4 wave (55) vertical) and could be decoded by a simple software only application with a sound card. (someone has to write it)... The total useful message capability is about 500 bytes transmitted every 2 minutes (at 50 baud). The uplink is very specialized and can ONLY BE DONE from one (or two) very special commmand stations. These satellites of course were the original Navy Navigation satellite system (also called OSCARS) and so the message would be in-place of the normal navigation data. SO in a sense, this is a downlink BROADCAST application. Since ham radio is two way, I'm stumped for applications. The total message capability of 500 Bytes can contain one long ARRL bulletin, or 20 APRS position/status reports, or say 20 or so APRS text messages, or say 50 callsign exchanges or maybe even 1 thumbnail image... but what's the application? Even if we allow say, INTERNET link to the command station for anyone to contribute to the twice per-day upload, then everyone's receiver application can receive them... For what? So Im looking for ideas. All I can come up with so far is: 1) ARRL Bulletins? (I don't even know how often ARRL sends bulletins...) 2) Navy/Army/AF MARS broadcast bulletins... 3) Internet message in-to-command-upload-to message RF downlink. Two stations do this to each other and it counts as a two-way QSO? 4) ... Every scenario of interest usually begins with the much higher value of UPLINK from the individual field station, not downlink.. Hence I am stumped. HUMMH... Maybe purely educational? If the software can run on any PC with a sound card connected to any scanner... Then every school can use it as a satellite downlink signal of interest.. What kind of thumbnail image can fit in 500 bytes? Send in your picture and get it downlinked on a given day? Etc.. Will need a DSP volunteer to write the sound card decoder.

[amsat-bb] Thanks for the TI Support
I want to offer my sincerest thanks to the satellite community, Drew, and AMSAT for the support that you gave us during the TI-2 Space this year. We are in day 4 of the teachers institute and will be wrapping up the day with some last minute satellite contact opportunities. But over the last three days, your support in making contacts with the teachers, and in particular, the dedicated SSTV activity on AO51 last night, has made the TI-2 Space a huge success this year. I wish each of you could have seen the glowing light bulbs in the teachers' heads at each successful satellite contact. I am confident that they will be taking what they learned this week back into their classrooms to make space alive for their students. Thanks for the patience you showed as these novice satellite operators learned the tricks of the trade. I can tell you that I am warn out (in a good way) facilitating their learning experience. (It is also a hoot to see 8 satellite ground stations, and antennas operating at one time.) I think we may have a record of work around the table via satellite awards. Thanks again for your support, and I'll be seeing you on the birds when I recover and am back at the home QTH next week.

[amsat-bb] TI-2 Space Operations
Hi All, The Dayton Amateur Radio Association sponsored ARRL TI-2 Space will be conducted next week in Dayton from July 12 through 15. The purpose of this teachers institute is to instruct teachers on how to access satellites for use in their classrooms. The four day institute will involve a lot of on-the-air activity on the birds. I hope that you will listen up for the teachers who will be working the birds for the first time and help participate in the TI by making contacts with them. They will be novice satellite operators so I hope you will forgive mistakes as they learn the ropes. It will be interesting to see how 8 ground stations operate from one location! (The stations consist of FT817s, ARROWS and computer controlled G5500 rotors.) If anyone needs a contact with W1AW/8, I will be using that call sign periodically while doing some demonstrations during the TI. If you have a specific request, let me know via e-mail and I'll listen for your call specifically. CU on the birds and I appreciate your patience during this TI.

[amsat-bb] Re: New Lindy's QRV
I can consistently copy the beacons on FO 29 and HO 68 down to the horizion using a larsen 2/70 mobile antenna with the larsen radial kit. The feed line is approx 60 feet of Belden 9913F. I typically connect the antenna to a comet duplexer to my mirage UHF amplifer which has a gasfet preamp and use my FT736 as a receiver, but the 736 can copy the beacons with the preamp switched off. I have an ARR gasfet preamp that works a bit better but is not TR switched and I usually don't bother with it. VO52 is also typically copyable down to the horizon with this setup. I haven't been on the FM sats in a while but don't recall any issues copying them either. I have been told by several people that my ears seem to do a better job than others at copying weak signals though (: - Original Message From: Bill Dzurilla billdz@yahoo.com To: amsat-bb@amsat.org Sent: Tue, February 9, 2010 6:23:18 AM Subject: [amsat-bb] Re: New Lindy's QRV Dave, I would be suspicious of the construction. I can get a few minutes of good copy from AO-51 on a high pass with just a rubber duck on an HT. If you do get a preamp, the run between the antenna and the preamp is critical, so if possible keep it short and use good coax. Ed seems to be having success with 4' of RG-58U, but generally the use of any RG-58U at 70cm is not a good idea. Here's a quick summary of my results with various antennas: * HT and rubber duck or other antenna mounted directly on the HT - success only at high elevations * HT and Arrow or Elk antenna, no preamp - success from horizon to horizon, if no trees or other obstructions * base rig and dual band omnidirectional ground plane, no preamp, 40' of RG-213U - success on most birds only when elevation is above 25-35 degrees * base rig and dual band omnidirectional ground plane, ARR preamp, 40' of RG-213U - success on most birds when elevation is above 15 degrees * base rig and Elk antenna on 12' pole at 15 degrees fixed elevation, azimuth rotation with old TV antenna rotor, ARR preamp, 70' coax run (my current setup) - full success from horizon to horizon on all birds, except in directions where blocked by trees or roof. The Elk is $135 shipped and the used rotor was $25, and this combo is by far the most effective I have used. My community has antenna restrictions, but so far no one has complained about the little 2' long Elk. The Elk could be replaced with a homebrew Cheap Yagi or tape measure yagi, which can be built for $10. I am not aware of anyone who is able to work the sats at low elevations with any type of omnidirectional antenna, even with the best preamp. You can have plenty of fun working the birds at higher elevations, but you will be able to work more passes and better DX (e.g., Europe on AO-7) if you can catch them at lower elevations. 73, Bill NZ5N __ Looking for the perfect gift?

However, many of the example projects appear unrelated to radio or may be commercial in nature, so they may not qualify for the amateur-satellite service. Wi-Fi equipment operates at very low power and relies upon provisions in the radio regulations allowing administrations to use frequencies for any purpose, provided they don't cause interference to stations operating in accordance with the Table of Frequency Allocations. Low power in this band fits the bill very nicely for short range use; not for space operations. Timing issues may also apply. Some good frequency planning is in order. 73, art.

Here's an interesting article from The Register: http://www.theregister.co.uk/2009/08/04/tube_sat/ Launch your own satellite for only eight grand Prospective world domination candidates apply here By Bill Ray • Get more from this author Posted in Telecoms, 4th August 2009 14:59 GMT Interorbital Systems is offering your own orbiting satellite for only $8,000, including launch, though evil geniuses might balk at the expected 2-week lifespan before a fiery re-entry. The plan is to launch 32 of the diminutive TubeSats into low earth orbit, around 310Km up, using a single Neptune 30 launcher (under development by=2 0Interorbital). The Neptune 30 will time release the TubeSats into orbits that decay within a few weeks, after which they'll burn up re-entering the Earth's atmosphere. The cost of each one is $8,000, though you'll have to pay up front to guarantee a launch slot, and put the satellite together yourself from the supplied kit. Stil, at least Interorbital Systems accepts PayPal. Fitting a doomsday machine into the 13.5cm long TubeSat, which is only 8.7cm wide, will challenge plans for world domination, but that will be where the genius comes into play. The company suggests you might use your TubeSat for everything from Earth-from-space video imaging to private e-mail or On-orbit advertising, though we're not sure what the audience figures would be for the latter. More realistically, buyers might like to bounce amateur radio signals off their own bird, or try experiments within orbital conditions. The radio aboard the TubeSat will operate at 902-928MHz or 2.4-2.4835GHz, the latter being ideal for Wi-Fi, as well as covering the bands allocated for amateur satellite operations - allowing Hams to fly even if pigs can't. Full specifications are available from Interorbital (pdf). Not that professionals will be allowed to buy TubeSats: The listed price is not valid for military, governmental, or large corporate entities. Members of these organizations should contact Interorbital Systems if interested in purchasing a TubeSat. Interorbital Systems has some form in space operations. It was a competitor in the X-Prize, and has entered Google's Lunar X-Prize to retrieve a bit of the moon. More practically, the company has been testing engines in the Mojave desert, but the TubeSat launches planned for next year will be the first time the company has flown a bird, even a small one. ® ___ Sent via amsat...@amsat.org.

[amsat-bb] W1AW Jul 28 AO-27
I will be putting W1AW on AO27 for a demonstration (HT and ARROW) during the teachers institute on July 28 (Tuesday) probably during the 1216(L) pass. Your assistance with the demonstration would be appreciated. If you would like a QSL of the contact, please send yours to WA8SME, and I'll take care of it. No SASEs required. 73, Mark Mark Spencer, WA8SME ARRL-The national association for Amateur Radio Education and Technology Program Coordinator mspen...@arrl.org http://www.arrl.org/FandES/tbp/ 530-495-9150 ___ Sent via amsat...@amsat.org.

[amsat-bb] G5500 Rotor Drift Issue
There have been a couple of recent posts about a G5500 voltage drift issue and some solutions. I'd like to thank those gentlemen for the posts and the solutions. I am in a unique position to be able to work with nine G5500 rotors side-by-side in preparation for the Teachers Institute II that I will hold at the end of the week. I noticed the same warm-up/calibration issue mentioned in the posts. I discovered that it took on average 10 minutes of warm up time for the voltage to stabilize, and this voltage is the reference on which the antenna position indications are based. The difference between the cold start and warm up position was around 10 degrees for AZ and 4 degrees for EL. Minor but irritating. I thought I'd try the easiest solution suggested first (changing the output cap on the regulator to .1uF) before I tried the more dramatic solution of changing out the voltage regulator. I simply tack soldered the .1uF cap on the exposed leads of the existing .01uF cap, and it worked like a charm. All nine rotor controllers fire up at 6.12 volts and hold that voltage throughout the operation of the rotor. This sure will make instruction of rotor setup and calibration a heck of a lot easier. Thanks for the suggests.

[amsat-bb] W1AW/8
Thanks to all who helped out with the satellite demonstration during the ARRL teachers institute held in Dayton OH today. The contacts were on AO27 during the 1515 EST pass. For those that contacted me (I was using W1AW/8) that would like a QSL, just send me a card at my call book address and I will return the favor (no SASE required). 73 and CU again from HQ (Newington) July 28th on AO27 and the afternoon pass (EST), there I will of course use W1AW.

[amsat-bb] Re: Way-OT: Re: Full Duplex HT's
I seem to have learnt something new today. I didn't think that front pannel programmable radios that were frequency agile could get an FCC approval (for Part 90 or other non ham use) these days. I also looked up the FCC ID on the FCC web site and found a copy of the manual that seems to confirm front pannel programability. - Original Message From: Kauto Huopio OH2LFM oh2...@sral.fi To: amsat-bb@amsat.org Sent: Thursday, June 11, 2009 4:37:56 AM Subject: [amsat-bb] Re: Way-OT: Re: Full Duplex HT's Its interesting that nobody seemed to look at their main page, where I found this statement: **WOUXUN Two-way radios are CE FCC and RoHS approved.** And further down the page: _WOUXUN Two-way radios are FCC approved.FCC ID:WVTWOUXUN03 Feeding this ID to Google I find this: http://www.chinatwowayradio.com/showroom/wouxun/certificate/index.htm --Kauto OH2LFM ___ Sent via amsat...@amsat.org.

[amsat-bb] Re: Way-OT: Re: Full Duplex HT's
Thanks. And of course aviation and some marine radios have various degrees of frequency agility, still I was under the apparently mistaken impression that user accessible front pannel programabiltiy was frowned upon in the land mobile bands in the USA. I'll have to see if they have also gotten a Canadian certification as I have a liscence for a comercial VHF frequency in Canada (: Regards Mark Spencer VE7AFZ - Original Message From: Ben Jackson b...@innismir.net To: Mark Spencer mspencer12...@yahoo.ca Cc: Kauto Huopio OH2LFM oh2...@sral.fi; amsat-bb@amsat.org Sent: Thursday, June 11, 2009 8:32:06 AM Subject: Re: [amsat-bb] Re: Way-OT: Re: Full Duplex HT's -BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Mark Spencer wrote: I seem to have learnt something new today.
