AMSAT NEWS SERVICE ANS-066 ANS is a free, weekly, news and information service of AMSAT North America, The Radio Amateur Satellite Corporation. ANS reports on the activities of a worldwide group of Amateur Radio operators who share an active interest in designing, building, launching and communicating through analog and digital Amateur Radio satellites. Please send any amateur satellite news or reports to: ans-edi...@amsat.org In this edition: * East Coast APRS Satellite Launch 11 March! * A new interference threat to the Ham Bands * SK: Dave Toth, VE3GYQ * Daylight Savings Time * AO-51 Survives Close Encounter With FORMOSAT-3 * A Self adjusting Orbit Scheme * ARISS Update SB SAT @ AMSAT $ANS-066.01 East Coast APRS Satellite Launch 11 March! AMSAT News Service Bulletin 066.01 From AMSAT HQ SILVER SPRING, MD. March 7, 2010 To All RADIO AMATEURS BID: $ANS-066.01 East Coast APRS Satellite Launch 11 March! You will be able to see it too over most of the mid-atlantic. I don't see a launch time or any other info yet. Here is what I have received: - A sounding rocket with amateur satellite operating on 144.39 MHZ APRS will rise to 100 miles or so for an 8 minute mission. The rocket (I think) is the Hall 12.067. The payload is called SOCEM/ADAMASat. There is a computer program and GUI to interface to your PC so you can grab the telemetry live. It is on: http://ssl.engr.uky.edu/adamasat_free_gui.exe It's a one shot deal, so I'm gonna have a backup TNC and HYPERTERM collecting everything. ADAMASat is the Antenna Deployment and Mono-filament Actuator Satellite. It's a 2U CubeSat designed by Kentucky Space as part of SOCEM, the Sub-Orbital CubeSat Experimental Mission. ADAMASat, which is scheduled to launch on Hall 12.067 out of Wallops Flight Facility on 11 March, will fly in space for roughly 8 minutes performing an engineering experiment and transmitting data down to Earth via APRS packets. More information on ADAMASat is available at http://ssl.engr.uky.edu/suborbital/adamasat Kentucky Space is hereby releasing to the AMSAT-NA community the ADAMASat FREE GUI, a free 32-bit Windows binary for amateur radio operators in the Eastern United States who are interested in tracking ADAMASat on its launch day. The GUI is a standalone application and upon opening it on his/her computer, the HAM will be greeted with a popup window which explains the steps required to track the payload. All that is needed is a Windows machine, a radio and TNC which can receive on 144.390 MHz, a serial or USB cable, and a suitable location. The GUI parses the APRS packets as they are received, graphing temperatures on-board the payload and reporting status of the mission in real-time. It also includes instructions on e-mailing the packet log to Kentucky Space to aid in post-processing, and a built-in aggregator for the official ADAMASat Twitter RSS feed. Disclaimer: Kentucky Space provides the GUI as is without warranties of any kind, and shall not incur any liability for any damages connected to the use of the GUI.

March 7, 2010 To All RADIO AMATEURS BID: $ANS-066.02 FCC to Permit Rescue Radio Robot in the 430 to 450 MHz Band Reports initially carried in the February 26, 2010 edition of Amateur Radio NewslineT Report 1698, and on the QRZ.com website say the FCC has issued a waiver of the Part 90 rules to permit a company called Reconrobotics Incorporated to sell a remote controlled security robot that will operate in the 430 to 448 MHz band. This is spectrum that is primary to the Federal Radiolocation Service but also encompasses the Amateur Service weak signal, satellite and repeater subbands. The waiver permits Reconrobitics to manufacture and sell a device called the Recon Scout. This is described as a device designed for state and local law enforcement and firefighting agencies, and secur- ity personnel in critical infrastructure industries. The Recon Scout can be thrown, dropped, or launched into potentially hazardous areas and can provide real-time video to an operator located a safe dis- tance away. Typical applications will include such things as checking a building prior to forced entry, searching vehicle undercarriages for explosives and searching for survivors in a burning structure. The Recon Scout transmits the analog video signal to the operator on one of three six megahertz channels. These are 430 to 436 MHz, 436 to 442 MHz, and 442 to 448 MHz. Reconrobotics says that multiple channels are necessary in order to avoid interference during incidents where multiple Recon Scouts are in use, but that such situations should be rare.

Hi Joel and all -This is a timely question for me. Yesterday I organized and ran (with the help of Wayne-W9AE) a AMSAT table at a local hamfest. I had the opportunity to meet many local hams both satellite ops and the curious. I extolled the virtues of AMSAT and the satellite community in general. A few points I noticed as an undercurrent in some of the conversations. We hams are generally a frugal bunch and in some cases just plain cheap. I had several antennas on display as well as several pictures, one was of an astronaut on a EVA installing one of our antennas on the outside of the space station. Some of the questions went like this, one guy asked, do you have to belong to AMSAT to operate satellites?, can I get this software (Satpc32) free on line? are these books available any where else? My response to these and similar queries was, see this picture? what do you think the shipping cost is? What we do, is rocket science, and rocket science is not cheap. How many active satellite operators do not belong to AMSAT? How many use pirated tracking programs. How many do not contribute something to AMSAT. Maybe some aspect of of AMSAT ticks you off, so you cut the cord. I'm sure some part of the government ticks you off, you don't move to Canada.

[amsat-bb] Re: Membership Benefits
Let's try it off the cuff... AMSAT is the central collection point for current satellite status, future technological development, international lobbying efforts, informational resources, contact coordination, information dissemination, etc (forgot debate) Without AMSAT and its BB reflector, a potential or existing Satellite operator would spend, days, weeks, months or maybe years Googleing resources to ease their introduction to the multiple aspects of the hobby. Has anyone seen an up to date hard/softcover book that answers the majority of the questions that we see go by the BB every day? Would 2.4 or 1.2 GHz have any activity if not for the AMSAT BB? How about automatic frequency control and tracking? What's the information worth to the individual?...that's a personal decision. But without communication, interest declines resulting in a who cares attitude...after all most of us have cellphones that can probably accomplish many of the tasks we perform through satellites less expensively.

[amsat-bb] Re: current handheld
At the moment there are no new HTs that are full duplex and work well enough for me to personally recommend. I've been pointing folks to going the two radio route, with anything that will receive 435, and anything that transmits on 2m (with PL for SO-50, 67, or 68). For a half duplex radio, I like the F6A as it will receive dc-daylight on FM and SSB/CW. I strongly suggest people use full duplex on the FM birds, but this rig works well as the receive portion. 73, Drew KO4MA -Original Message- From: Bob- W7LRD w7...@comcast.net Sent: Mar 7, 2010 2:09 PM To: amsat-bb@amsat.org Subject: [amsat-bb] current handheld I have been asked- what is the best current handheld for FM sats?

Hi Bob, The new Alinco is the only current-production HT that will operate full duplex; but like others, I hear rumblings about a TH-D7 replacement from Kenwood later this year. The D7 was full duplex. Posters here an elsewhere haven't given the Alinco high marks for its abilities to work the FM satellites. I haven't tried it, so I hope those who have some experience with it will respond to you. All of that being said, I would recommend the Kenwood TH-F6A from the group of currently available non-full-duplex radios for one major reason - its general coverage receiver is all mode. I borrowed one from a ham friend several months ago and, over the course of a weekend, use it as my receive radio with a FT-817ND as my transmit radio to make multiple contacts on all of the then-active linear satellites (AO-7 Mode B, FO-29 and VO-52). It performed very well as I worked all passes without a receive preamp for either VHF or UHF. It will work the FM satellites, while providing the bonus of giving newcomers a chance to copy AO-7, FO-29, HO-68 in linear mode and VO-52. I suspect that when they've heard a few passes of the linear satellites, they will be interested in trying to get on them.

[amsat-bb] Re: Current Handheld
... what is the best current handheld for FM sats?? We do not have a currently-manufactured TRUE DUPLEX HT available. Alinco tried - but the sub-band receive performance on their DJ-G7T is gruesome. I use and like the Yaesu FT-60R - for MANY reasons ... -Receives 108 to a gig -bulletproof case -strongest belt clip of any amateur HT chassis on the market -easy to manually program -1,000+ memories -large, easy-to-read display -and a battery situation that is great. Load up the optional FBA-25 AA alkaline tray with alkalines or NiMH cells, and you have FULL TX POWER available, is needed. Do that on, say, a Kenwood TH-F6a, and you have ONE-HALF WATT TX power. Oh - and the Yaesu FT-60R can be programmed for split freq ops - where is receives on 440 and transmits on 2M. Overall, it is a tremendous value for your money. Under $200 at HRO and AES and other authorized Yaesu dealers. Clint Bradford, K6LCS 909-241-7666 ___ Sent via amsat...@amsat.org. Opinions expressed are those of the author. Not an AMSAT-NA member?

All of my satellite contacts have been with the TH-F7E which is the European version - no 220MHz, but no cellphone hole either. What's especially handy is you can open it up to work on PMR frequencies too, so I can bung in the channels for a site where I'm working and use it to test commercial gear.

You can also download the service manual and change these parameters yourselves but this is probably not something that should be done. Comparing it to my TH-D7 it's not that bad. They changed something on the 23cm too but i'm not sure what the issue was there. Kai Gunter LA3QMA ___ Sent via amsat...@amsat.org. Opinions expressed are those of the author.

E5.000 [Updates of this firmware version] 1: RIT/TXIT functions / added. 2: Reverse function in repeater operation / bettered. 3: Beep sounds at turn-off the power / added. 4: CTCSS tone of Auto-repeater memory / bettered (give priority to the tone in memory, not in VFO while auto-repeater is ON) 5: Welcome-screen setting / bettered. 6: New scan mode added = turns on the LCD light when scan stops. Very convenient operating G7 in the dark. 7: Firmware update operation: accepts the command only when the battery-icon shows full. 8: Minor bugs fixed. Previous firmware: Bettered receiver performance around 320MHz range. I have not tested this on the birds. But the local repeater using the same antenna. Not a very advanced test. Receiving the repeater before upgrade, flashing the firmware and test again from the same spot. Anyhow the original antenna is not good on VHF but i think the UHF/SHF is better. Using the original antenna for the TH-D7 on the radio you gain better signal on the Alinco. So i have replaced the antenna for a SC951 SureCom for V/U and SHF and now it's better on VHF too. On the birds i probably want to use another antenna but the SC951 should work ok and better than the original on V/UHF. For SHF i have nothing to compare them on. I really like the dual-memorybank(splitband) so they are perfect for the birds. But i have not done any QSOs on the birds using this radio. But with the dual VFO control it's probably bnetter than the TH-D7 as you can adjust for dopler on RX on the Alinco. (The TH-D7 can only adjust the band you are TXing on) So then i just have to try AO51 ;o) i just wanted to say that they have done something with the filters and i think they have adjusted more than just the 320MHz range even if they don't say so. They are responding relatively fast on e-mail if you have any questions or suggestions for new functions or to change something into the better. Kai Gunter LA3QMA ___ Sent via amsat...@amsat.org.

[amsat-bb] Re: Current Handheld
No full duplex handheld - here is a simple solution. Use two rigs. Buy a 5w 2m radio for the uplink. Several good ones available available at low cost. If using an Arrow run separate cables for each radio, this avoids the diplexer which some on this list report as a source of extras loss. Works fine for me 73 John G7HIA From: Clint Bradford clintbra...@earthlink.net To: amsat-bb@amsat.org Sent: Sunday, 7 March, 2010 20:23:12 Subject: [amsat-bb] Re: Current Handheld ... what is the best current handheld for FM sats??

Hi Guys, I just ordered the microphone/headphone cable from HRO for my DJ-7G so I will soon be able to try it out on full duplex.

[amsat-bb] Re: current handheld
Years ago I did a test of the various handheld radio's available for sat use. I rated the TH-F6A a distant last. Reason is that its front-end is very sensitive to inter-mod. The test was performed in front of HRO in DE. See my HT test report on my webpage. It can be found by navigating to QRZ.com then lookup kb2m. I also remember when I was on a business trip to Houston. While there I meet with Jerry k5oe, Bruce kk5do, and Al n5afv for dinner(I have a picture of the group if anyone is interested). After dinner we went to the parking lot to work an FM bird. As my F6A was deaf from the urban inter-mod I had to borrow someone's HT to finish making a contact. When I got home I sold the Kenwood. It might be good out in the country, but it sucks in the city!... 73 Jeff kb2m -Original Message- From: amsat-bb-boun...@amsat.org [mailto:amsat-bb-boun...@amsat.org] On Behalf Of Tim - N3TL Sent: Sunday, March 07, 2010 15:15 PM To: 'Bob- W7LRD'; amsat-bb@amsat.org Subject: [amsat-bb] Re: current handheld Hi Bob, The new Alinco is the only current-production HT that will operate full duplex; but like others, I hear rumblings about a TH-D7 replacement from Kenwood later this year.

[amsat-bb] videos from XE2/WD9EWK (DM21) and Yuma hamfest in February 2010
Hi! I'm slowly getting the hang of video and putting it online in a usable form. I have placed 3 videos on YouTube this evening. One video is of a demonstration from the Yuma (Arizona) hamfest on 20 February 2010 where Kevin KJ6DDS and I worked the microphone. Larry KI6YAA operated the video camera (my Nokia N900 phone). At the end of the video, a Marine Corps Harrier jump jet was making its approach to land at Marine Corps Air Station Yuma, which is across the street from the hamfest site. That video can be seen at: http://www.youtube.com/watch?v=gwyFsk9tFAc The other two videos were from an AO-51 pass I worked as XE2/WD9EWK from grid DM21jw in northern Baja California on 19 February 2010 at 0019 UTC. On this afternoon, I was accompanied by Larry KI6YAA and Kevin KJ6DDS, and Alex XE2BSS/N2IX worked the video camera. We parked along the highway on the Laguna Salada, a dry salty flat area near the Colorado River on the way toward the Gulf of California. The video had to be split into two parts, to comply with YouTube's 10- minute limit on video length. The first 7 minutes can be seen at: http://www.youtube.com/watch?v=JW5-hL3SDig The remaining 7:14 can be seen at: http://www.youtube.com/watch?v=2k2yAMGeALc When we were down at DM21jw, it was windy. XE2BSS tried his best to shield the phone/camera's mic from the wind, and allowing the speaker that was connected to my radio to be heard in the video. I worked several other passes from this location, all of which I have MP3 audio recordings of, but this was the one we decided to make a video of. I hope to have the QSL cards from last month's trip to Baja California and the Yuma hamfest ready this week. I've received a lot of QSL requests already, especially for QSOs with DM21. :-) Please be patient, the cards will be on their way. And, eventually, the QSOs will make their way into ARRL's Logbook fo the World system (more on that in a separate message). 73!

It might be good out in the country, but it sucks in the city!... I found that my TH-F7E is badly affected by pager rip in certain spots around Glasgow, especially with an external antenna. Oddly enough, some of the high sites on tower blocks I maintain are really bad, and some are practically silent. Using it for satellite it seems that the diplexer in my homebrew crossed yagi knocks enough of the out-of-band crap out to prevent this. It's not nearly so bad for intermod on UHF as it is on VHF, too. This could be because there are fewer UHF high-power paging transmitters here (just a wee bit of mobitex, mostly).
