You might want to hold onto the TH-F6A, even if you get a TH-D72A. The TH-F6A has an all-mode receiver, which could be paired up with something like an FT-817 to make a small station capable of all-mode, full-duplex satellite operation. The TH-F6A's non-FM receiver is not as sensitive nor as selective as other radios like an FT-817, but the FT-817/TH-F6A combination makes for a nice station to show off at demonstrations. 73!

Hi, I hope I have not been missing something major on my Kenwood TH-F6 HT, but I don't think it does full duplex. You can receive two channels simultaneously, yes. But I don't believe you can transmit on one while simultaneously listening on the other. That's the capability that you need to confirm you can "hear yourself" and confirm that you are reaching the satellite and the sat is sending your voice back to you. If I'm wrong about the TH-F6a that would be a bummer! I'm looking for an excuse to replace it with a TH-D72a 73, Burns W2BFJ > Message: 7 > Date: Mon, 15 Apr 2013 09:52:59 -0500 > From: "ac4ny_1" <ac4ny_1(a)juno.com> > To: <amsat-bb(a)amsat.org> > Subject: [amsat-bb] Re: The Ham Radio Bucket List > Message-ID: <001101ce39e8$eedf2380$ > e301a8c0@joe8b7a02056b7> > Content-Type: text/plain; format=flowed; charset="iso-8859-1"; > reply-type=original > > Hi Bob: > > I use a Yaesu FT-60r with a homebrew handheld 3 element loop yagi.

The Ham Radio Bucket List
by Les Rayburn 15 Apr '13

15 Apr '13

I've been a ham well over 40 years, since my childhood. Back then, I could barely afford the Heathkit transmitter, Halicrafters receiver, knife switch, and longwire antenna that made up my shack. My elmer used to let me borrow his copy of QST and I'd dream about all the great adventures that I'd have "someday" in ham radio. Being a child of the Space Age, key among them were anything related to the New Frontier. EME (Moonbounce), Meteor Scatter, and satellites all seemed like the stuff of science fiction---and I longed to experience them all. But they were exotic, and required equipment far beyond my reach. I resolved to accomplish them all someday and added them to a sort of ham radio "bucket list" that I hoped to accomplish before my ham career was over. Five years ago, shortly after getting started in weak signal VHF work, I checked off the first item on that list. Working meteor scatter contacts with the aid of WSJT software, and during a Perseid shower, even using SSB. What a thrill to make contacts off the ionized gasses of those tiny rocks. Thanks Joe Taylor! Tonight, I managed to check off a second. I worked Art, K4YYL on FO-29, a Japanese amateur satellite! My journey to the "birds" started about a month ago when I joined AMSAT, determined that 2013 was going to be "the year" when I finally got active on satellites. I purchased a copy of SATPC32 software, because I knew that it could control my IC-910H--hopefully making it easier to get active. After listening to a few passes on both the FM and the SSB/CW birds, I decided to try my luck on the less-crowded FO-29. A brief CQ was quickly answered by Art. I adjusted the tuning knob just a bit to correct for the Doppler effect, and voila! there he was clear as a bell. We had a brief QSO of perhaps ten minutes or so, and then we signed. I was quickly called by K4FEG near Memphis in EM55---who just wanted to welcome me to the birds! Man, what a thrill! And it wasn't tough at all. I'm using a 7 element 432 antenna tilted up to 15 degrees (fixed) and a 6 element 2 Meter beam tilted up to about 10 degrees (fixed) both inside my crowded attic. The SSB Electronics pre-amp helps a ton on 432, and the 1/2" hardline makes sure that I don't lose too much signal. So far, I've been able to copy the birds down to about 2 degrees above the horizon using this setup. Now to attempt that EME contact! I've got a 12 element Yagi just waiting to deploy in the driveway once the weather warms a bit. Hoping to use WSJT to work one of the monster stations on EME. All this in a deed-restricted HOA neighborhood. I wasted 35+ years on HF----man, all the fun really is in the World Above 50 MHz! Thanks for helping to make a boys dreams come true at age 51! -- 73, Les Rayburn, N1LF 121 Mayfair Park Maylene, AL 35114 EM63nf 6M VUCC #1712 AMSAT #38965 Grid Bandits #222 Southeastern VHF Society Central States VHF Society Life Member Six Club #2484 Active on 6 Meters thru 1296, 10GHz & Light

Hi Bob: I use a Yaesu FT-60r with a homebrew handheld 3 element loop yagi. I only work half duplex. For full duplex I use a Baofeng UV3R (cheap but does work). The Kenwood TH-F6A is great. Make sure the HT will do cross band. Also use a good duplexer. There are many other great radios out there and a lot more operators on here that has more insight than I. I been on the birds since 2000. Licensed since 1979.

On the AMSAT-BB Hector reported "We had just a 88 seconds window. I was operating portable from on top of a tall building as before. Satellites are always fascinating! Thanks very much to David for this great contact and new grid!" Based on QRZ.com, the distance between the two stations is 7330.6 km. [ANS thanks Hector, CO6CBF for the above information] --------------------------------------------------------------------- GS3PYE/p Satellite Operation Planned From Inner Herbrides Islands Members of the Camb-Hams will once again activate the Isle of Mull (IOSA NH15, SCOTIA CN10, WLOTA 2485), Inner Hebrides, as GS3PYE/p between May 10-16. The Camb-Hams have been activating the Scottish Isles each year since 2008. Look for thirteen operators to be active on all bands and many modes from 160-2 meters as well as 472 kHz. The HF bands will be covered by five simultaneous stations, while 6m, 4m and 2m stations will have a great take-off towards the UK and Europ from the island's south-east coast in IO76 square. They will have an antenna elevation system for 2m EME activity and will also be on many of the VHF/UHF satellite passes. WSPR beacons will be operating on most of the inactive bands to help find the best propagation. Contest operations will take place in 70 MHz CW on May 12th and 432 MHz UKAC on May 14th. The group will be active on the major social networks before, during and after the trip. You can check on progress or interact with the operators via their blog at <dx.camb-hams.com> or through Twitter <twitter.com/g3pye>, Facebook <facebook.com/CambHams> and YouTube <youtube.com/CambHams>. Previous trips have generated some great audio and video recordings of the GS3PYE/P signal from around the world. Check their previous blogs and their YouTube channel and see if you can post a better recording. Please E-mail <skeds-2013(a)camb-hams.com> to arrange skeds on the more challenging bands and modes. VHF and EME skeds will also be made via ON4KST and N0UK's EME Chat. All links are available via <dx.camb-hams.com>.

A network of four ground stations, located at the IUZ in Bochum/Germany, CNES in Toulouse/France, NICT in Koganei/Japan and amateur radio station DL0SHF in Kiel-Ronne/Germany receives this data, and uses turbo-decoding software written by AMSAT-DL. The Bochum station is run by AMSAT-DL e.V. and IUZ Bochum Observatory, with the support of the Federal Ministry of Economics and Technology and DLR. Said Doug Biesecker, NOAA Space Weather Prediction Center: "Thanks to the wonderful work of our colleagues running the station in Bochum and the support of DLR, we can now be sure of receiving real-time data from the NASA/STEREO satellite throughout the life of the mission. The STEREO data has proven to provide significant benefits to space weather forecasting and is used by NOAA on a daily basis to ensure the best possible forecasts. Space weather increasingly threatens the technological infrastructure of our modern world, with demonstrated impacts on global positioning, power grids, and high frequency communication systems." The switch to Turbo Codes has improved reception capabilities of the ground stations by about 2 dB, which is a very welcome improvement giving the increasing distances - 269 and 286 million kilometers respectively - that need to be covered.

The ARRL’s Education & Technology Program (ETP) offers two programs that can help make this happen, but the application deadlines are fast approaching: The deadline for the 2013 Teachers Institute on Wireless Technology (TI) is May 15, while the deadline for equipment and resource grants was May 1. Teachers Institute on Wireless Technology Seats are still available for the two introductory Teachers Institute (TI-1) sessions offered this summer, one at ARRL Headquarters in Newington, Connecticut (July 8-11) and one in Rocklin, California (July 15-18). These four-day intensive professional development seminars provide training and resources for introducing basic electronics, the science of radio, space technology and satellite communications, weather science, microcontroller fundamentals and basic robotics into classroom instruction. The curriculum is designed for motivated teachers who want to learn more about wireless technology and share that knowledge with their students. Resources, travel, and room and board expenses are provided by donations to the Education & Technology Program Fund. The ETP is also offering an advanced Teachers Institute (TI-2) session that focuses on the basic electronics behind sensor technology. Teachers will receive instruction in the use of a selection of sensors (such as temperature, pressure, position and humidity), analog-to-digital conversion techniques, the microcontroller programming involved in accessing the sensors and the use of radio (packet radio-like data links) that connect the sensor outputs to the user. Participants will also explore numerous deployment systems that they might use in their classrooms, including land and water robots, buoys, balloons and satellites. This four-day professional development workshop is sponsored by Dayton Amateur Radio Association and is held in Dayton, Ohio (July 22-25). The deadline for both the TI-1 (Connecticut and California) and TI-2 (Ohio) sessions is May 15. Apply now! http://www.arrl.org/teachers-institute-application Equipment and Resource Grants ETP grants for school radio stations are awarded to schools that provide a plan for using Amateur Radio as part of an enrichment program and/or as part of in-classroom learning. Find more information, as well as applications for a School Station Grant or for a Progress Grant, on the ETP Grants web page http://www.arrl.org/etp-grants. The deadline for applications was May 1.

Those of you that have been involved with ARISS from the beginning know that Ken was one of the ARISS pioneers. Ken was a member of the first cadre of ARISS delegates and was integral in leading the startup of ARISS. Ken’s intimate knowledge of the space agencies, resulting from his background as a Senior Executive in the Canadian Space Agency, was crucial in helping ARISS formulate the strategies needed to garner support across our international space agency partners. Also, his in- depth understanding of amateur radio policy and connections into the ITU were important factors in helping the ARISS team prepare themselves to develop and operate the unique, multi-national amateur radio platform on ISS that is ARISS. He was a key contributor in guiding the ARISS team in frequency coordination, licensing and callsign strategy. He also was integral in developing ARISS’ terms of reference, our policy for assigning delegates, and he led the effort to nominate and elect our first set of officers. I, for one, will certainly miss Ken’s leadership and guidance. He helped the ARISS program grow from infancy to the strong, international Educational Outreach program that it is now. I note that even just a few weeks ago Rosalie White, K1STO and I solicited Ken’s guidance on some ITU matters that our ARISS international team were addressing. In all matters, Ken was a “Gentleman’s Gentleman”---the “best of the best. ” His presence and support will be sorely missed by me. And by all in the ARISS community. On behalf of the ARISS team, I want to extend our condolences to all Ken Pulfer’s family and friends. May Ken Rest in Peace. [ANS thanks Frank H.

The satellite is built around the Nexus smartphone which will be running the Android operating system and will be enclosed in a standard 1U cubesat structure. The main function of the phone is to act as the Onboard Computer, but the mission will also utilize the phone's SD card for data storage, 5MP camera for Earth Observation, and 3-axis accelerometer and 3-axis magnetometer for attitude determination. One of the nanosatellites, powered by the HTC Nexus One smartphone, will send back pictures of Earth. The other two, running on the Samsung Nexus S, will have two-way S-band radio allowing them to be controlled from Earth. With a short lifetime of only about one week, the satellites have no solar cells and operate on battery only. An article on SpaceRef.com describes the Antares test flight, dubbed the A-ONE mission, as the first of two missions Orbital is scheduled to conduct in 2013 under its Commercial Orbital Transportation Services (COTS) Space Act Agreement with NASA. Following a successful A-ONE launch, Orbital will carry out a full flight demonstration of its new Antares/Cygnus cargo delivery system to the International Space Station (ISS) around mid-year. In addition, the company is also scheduled to launch the first of eight operational cargo resupply missions to the ISS in 2013 under the Commercial Resupply Services (CRS) contract with NASA. All COTS and CRS flights will originate from NASA's WFF, which is geographically well suited for ISS missions and can also accommodate launches of scientific, defense and commercial satellites to other orbits. The Antares medium-class launch system will provide a major increase in the payload launch capability that Orbital can provide to NASA, the U.S. Air Force and other customers. (Reference: http://spaceref.com/news/viewpr.html?pid=40502) The Antares launch includes the commercial DOVE-1 satellite, a technology development experiment. The satellite had requested IARU coordination for a 1 watt transmitter on 145.825 MHz to downlink a 1200 baud AFSK AX.25 beacon with telemetry and health data. The IARU reported in January that DOVE-1 will no longer be using frequencies in the amateur radio bands based on information posted on the IARU satellite coordination web page for this mission.

STRaND-1, was launched on February 25 at 1231 UT on the PSLV-C20 rocket from the Indian Space Research Organisation (ISRO) Satish Dhawan space centre. Both Mike Rupprecht DK3WN and Nader Omer ST2NH have reported that no signals have been heard since Sunday. Radio amateurs are asked to listen for STRaND-1 transmitting a 9k6 bps AX.25 signal around 437.568 MHz (+/- Doppler) over the next few days.

The fourth round of selections in NASA’s CubeSat Launch Initiative also included a team of high school students at the Merritt Island High School in Brevard County, Florida. They plan to build a cubesat containing two accelerometers to measure the amount of vibration in the Poly Picosatellite Orbital Deployer, or P-POD case that holds the cubesats during launch and then deploys them. The high school is partnering with students at California Polytechnic State University in San Luis Obispo. The Cal-Poly CubeSat, dubbed CP9, is actually two cubes that contain accelerometers, plus a radio to transmit data back to Earth for the high school students to analyze. The Merritt Island High School cubesat, named StangSat, will stream data to the CP9 in real time during the launch using Wi-Fi. “We’re going to be demonstrating that wireless transmissions inside the P-POD aren’t going to harm the launch,” said Adam Darley, a senior at Cal-Poly who is serving as the CP9 project manager. “If we can demonstrate that, then it will act as a platform to being able to stream information without a radio link.” The Merritt Island High School Cubesat team has more information and photos posted on their Facebook page.
