Arrow antenna for sale
by John Price 04 Mar '13

04 Mar '13

I have a arrow antenna in excellent condition for sale. It has the duplexer built into the foam handle. It also has the very nice blue roll up storage bag with it. This is an estate item and it appears to have been used very little if ever. Anyone interested before it goes to eBay please email me off list. 73's << John -- N4QWF Amateur Radio Operator Email N4QWF(a)AMSAT.ORG Formerly KC4AHW VK3FEZ DXCC #33,478 VUCC SAT #135 WAS SAT #296 51 on AO-51 #13 LON -79.256 LAT 37.459 Grid FM07il >From the Foothills of the Blueridge *Life should not be a journey to the grave with the intention of arriving safely in a pretty and well preserved body, but rather to skid in broadside, thoroughly used up, totally worn out, and loudly proclaiming - "WOW, What a ride!"

Fw: Foxdelta ST-2 / LVB Tracker
by Matty Cunningham 04 Mar '13

04 Mar '13

Hi Kyle, I have an ST2 myself and use an old Cornell Doublier for azimuth, and an Alliance type U100 for elevation. I put the control interface with a seperate PSU into a 2U cabinet that was used for other equipment, along with the transformers/phasing capacitors for each rotator - I used relays for switching the motors/directions with some diodes to stop reverse spikes from the relays getting back to the interface transistors. I had no problems at all using this with a small dual band 2m/70cm yagi from Sandpiper, last year I upgraded my antennas and found a few issues with the controller not wanting to play. I found if I disconnected my radio from the antennas, I had control of the rotators - re-installed the original antenna, and finding everything working again, I worked out I had some sort of earth loop weirdness going on. My Sandpiper dual bander has a dipole feed for each band, isolated from the antenna boom, the new larger yagis for each band both have a gamma match, and grounded booms - this was what caused my issue with my controller. Switching from an aluminium pole, to fiberglass for the elevation boom fixed my problem - not sure if this would possibly help with your scenario, it may be worth looking at. I would also check to make sure you have run through the calibration procedure for the interface. I've successfully used the tracker with various bits of software (HRD rotator software, SDR V.1 console and others). If I was to buy another, I would go for Howards LVB version from Amsat. Good luck with getting it up and running. Matty MD0MAN Date: Sat, 2 Mar 2013 12:19:01 -0600 From: "K&R Yoksh" <yokshs(a)gmail.com> To: <amsat-bb(a)amsat.org> Subject: [amsat-bb] Fw: Foxdelta ST-2 / LVB Tracker Message-ID: <156EAB2B86C041DE8991016DDFEFDEE0@main2> Content-Type: text/plain; format=flowed; charset="iso-8859-1"; reply-type=response Hello Howard, Thanks for the reply. I have posted on the FoxDelta email group, but haven't received a reply. I should mention that I don't think that the ST-2 is malfunctioning, nor do I think that your code has a problem. I just have a different type of rotator than the typical Yaesu. It would certainly make things easier if I did, but it would be quite an ordeal to change the rotator in my situation. I did not know the background of the Foxdelta vs. the LVB. I do understand that Amsat gets a donation with every LVB, and my intention was / is to donate again to Amsat when I can. I can certainly see where you're coming from re: the IP. I guess if nothing else, the ham satellite community as a whole benefits from your public domain IP, which helps generate more interest in satellites and satellite operation. As far as the hardware and software goes, I'll look at the grounding, but I am thinking that the issue lies in the fact that CDE uses a 12 volt feedback POT.. I built a simple resistor voltage divider back when I first got my Kansas City Tracker, so that the KCT would see 0-5v instead. This approach gives the KCT (or LVB) the correct voltage range, but I believe it may lower the resolution of the feedback system? I'll also try some ferrites on the leads from the CDE rotator box, in case transients are to blame. I'm certainly no programmer, but the software seems to stop the rotator immediately when the ADC sample value equals the target azimuth value. Once the antennas stop moving, the final location is different by 20 degrees or so. Once the rotator stops moving, however, the software doesn't recheck to see if the rotator is actually where it needs to be. My idea was to either change the ADC sample rate, or perhaps add a pause after the rotator stops, and repeat the routine to "fine tune" position. This is why I have been trying to recompile your source.. I've already got PICs programmed with your 0.7 and 0.9 HEX files.. 73, many thanks. Kyle K0KN

by Andy Brian 03 Mar '13

03 Mar '13

HI, I'm looking for anyone who using DL7AOT rotor hardware and WispDDE. I have problem with WispDDE when the DDE sending Az or El to DL7AOT HW number without decimal point like AZ 15 the FW on PIC16f84 read the azimuth like 150 degree (look like the FW need to see dot "." for correct decode) Is possible to tell the Wisp DDE programme to send the number like AZ 15.0 instead of AZ 15? thanks for answer 73 Andy

Working from FK97
by Nikolai Ozerov 03 Mar '13

03 Mar '13

Hello everybody, I am planning to attempt activating FK97 on the SO-50 passes from March 11 through 16, 2013. Only day-time passes will be attempted. Unfortunately, some of them are not very suitable for making contacts with North America ... Are there any South American stations active on the FM birds ? Anyway, watch me on these days if you are interested in the new grid square. Nikolai / V26NK.

AMSAT NEWS SERVICE ANS-062 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-editor(a)amsat.org In this edition: * Vanderbilt-AMSAT RadFxSat Cubesat Selected for NASA ELaNa Program * AMSAT Shows New President’s Club Pin * 5th European CubeSat Symposium, 3-5 June 2013, Brussels - Belgium * American satellite starts transmitting after being abandoned in 1967 * STRaND-1 Information and Telemetry * ARISS NEWS * AMSAT-DC Workshop on Portable Satellite Ground Stations * AMSAT Forum at ACADIANA ARA Hamfest - Free Admission Coupons for Youth * Korean OSSI-1 Ham Radio CubeSat Frequency Coordinated * ARRL Offers Two Sessions of their Teachers Institute SB SAT @ AMSAT $ANS-062.01 ANS-062 AMSAT News Service Weekly Bulletins AMSAT News Service Bulletin 062.01 >From AMSAT HQ SILVER SPRING, MD. DATE, 2013 To All RADIO AMATEURS BID: $ANS-062.01 Vanderbilt-AMSAT RadFxSat Cubesat Selected for NASA ELaNa Program On February 26th, NASA announced the winning projects for the fourth round of their CubeSat Launch Initiative. Project Selection was based on technical feasability and the assessed merit for conducting technology demonstrations, STEM education, and science research. These selected projects are eligible for a free launch on NASA Educational Launch of Nanosatellite (ELaNa) missions as auxiliary payloads on launches planned for 2014, 2015 and 2016. The 24 winning cubeSat proposals came from universities, a Florida high school, non-profit organizations and NASA field centers. AMSAT partnered with the Institute for Space and Defense Electronics (ISDE) at Vanderbilt University to develop our winning proposal. The official name of the project is RadFxSat and we were selected at priority 15 out of the 24 winners. AMSAT and ISDE plan to fly a Fox-1 type satellite with a sophisticated space radiation effects experiment to be developed by ISDE. This experiment is intended to improve computer modeling of radiation effects and help improve the survivability of modern semiconductor devices in the harsh radiation environment of earth orbit. AMSAT is especially interested in this area of science research since it affects our ham radio satellites. This project also represents an exciting "first" for AMSAT with the satellite's primary mission being science research. We believe that partnering on science and education missions will open up new launch opportunities for AMSAT satellites in the future. Of course, RadFxSat also carries the same ham radio FM transponder as Fox-1 but on a different frequency pair. We believe we will have enough power to run the FM transponder simultaneously with the science mission most of the time. The transponder capability was an important component of our NASA ELaNa proposal since it enhances the opportunities for formal science, technology, engineering and math (STEM) education via "hands-on" school activites using an actual communications satellite. It also allows informal groups such as the boy scouts, girl scouts and ham radio clubs to introduce radio and satellite communications to our young people. AMSAT aims to show that STEM education can be exciting and fun!

An Amateur Radio Astronomer in North Cornwall accidentally picked up the signal and after cross checking with various lists, has identified it as LES1 built by the Massachusetts Institute of Technology and launched in 1965. The satellite failed to reach its intended orbit owing to a wiring error and has been drifting out of control ever since. Phil Williams G3YPQ from near Bude noticed its peculiar signal drift caused by its tumbling end over end every 4 seconds as the solar panels become shadowed by the engine. ‘This gives the signal a particularly ghostly sound as the voltage from the solar panels fluctuates’ Phil says. It is likely that the on board batteries have now disintegrated and some other component failure has caused the transmitter on 237Mhz, to start up when its in sunlight. LES1 is about the size of a small car, It is not likely to re-enter the atmosphere for a long time as the orbit is still relatively high. It poses no threat other than that caused by the thousands of other pieces of space junk in orbit. Phil says its remarkable to think that electronics built nearly 50 years ago, 12 years before Voyager 1, and long before microprocessors and integrated circuits, is still capable of working in the hostile environs of space. Listening to the signal you can easily imagine the craft tumbling over and over every 4 seconds and the transmitter starting up as the sun rises. He refers to the hobby as ‘Radio-Archeology’! [ANS thanks Phil Williams G3YPQ and Southgate ARN for the above information] --------------------------------------------------------------------- STRaND-1 Information and Telemetry STRaND-1 carries an amateur radio AX.25 packet radio downlink on 437.568 MHz using 9600 bps FSK modulated data with HDLC frame, NRZI encoding. Free satellite tracking software: • SimpleSat Look Down http://www.amsat-uk.org/?p=8217 • Gpredict http://gpredict.oz9aec.net/ • Orbitron http://www.amsat-uk.org/?p=9051 Dr Chris Bridges would be delighted to receive all available telemetry files by email to C.P.Bridges(a)surrey.ac.uk Mark Hammond N8MH has provided these tips to decode STRaND-1: (1) Sprint-2 TNC set at 9600 baud in KISS mode (or any 9600 TNC in KISS mode probably) (2) Using this software to capture http://www.dk3wn.info/files/online_kiss_plus.zip (3) And using this software to decode the captured KISS files http://www.dk3wn.info/files/kissdump.zip Thanks to Mike Rupprecht DK3WN for the excellent software. Jan PE0SAT describes how he used the free TNC emulator software AGWPE and SDR# to decode the telemetry. This approach means you don’t have to buy a dedicated hardware TNC it simply uses your existing PC and radio that supports 9600 bps data: (1) Record a pass using SDR# and a FUNcube Dongle Pro+ and save the IQ wav file so you can work with it after the pass. (2) Configure AGW Packet Engine (AGWPE) as a 9600 baud modem using your audio mixer as input. If you don’t have an audio mixer, use audio VAC to route the received audio to the AGW audio input. (3) When the AGW packet engine is running use AGW-Online-KISS from DK3WN to connect to the packet engine and decode the telemetry. (4) Open the IQ wav file within SDR# and playback the recorded file and tune to the correct receive frequency, now you can see decoded data within Online-Kiss. (5) Feed the files captured to KISS-Dump Descriptions of ONLINE KISS +, AGW ONLINE KISS and KISS Dump + are at http://tinyurl.com/SatSoftwareDK3WN/ The free AGWPE soundcard packet software AGWPE.zip is available at http://www.sv2agw.com/downloads/ Guide on how to use AGWPE http://www.soundcardpacket.org/ Latest Keps for the objects from the PSLV-C20 launch.

Artist and radio amateur Hojun Song DS1SBO has spent 7 years developing his Open Source Satellite Initiative satellite OSSI-1. He has designed and developed it from scratch using readily available components rather than expensive space qualified hardware. It has a beacon in the 145 MHz band, a data communications transceiver in the 435 MHz band and carries a 44 watt LED optical beacon to flash Morse Code messages to observers on Earth. OSSI-1 is planned to launch on April 19, 2013 into a 575 km 64.9° inclination orbit on a Soyuz-2-1b rocket from the Baikonur launch facility in Kazakhstan along with the Bion-M1, SOMP, BEESAT 2, BEESAT 3 and Dove-2 satellites. The IARU amateur satellite frequency coordination panel has announced frequencies for a downlink on 145.980 MHz and an uplink/downlink on 437.525 MHz.

Re: Foxdelta ST-2 / LVB Tracker

Does the controller have motor protection logic/timers to detect if the motor is stalled? This sounds like normal behavior I discovered with the TAPR TakBox. There is a timer that detects if the ADC disagrees with where the controller thinks the rotor should be pointed and stops the motor. It takes a number of seconds (in the timer) to reset the controller. What I found was that the ADC always lagged where the controller thought the antenna should be pointed. The timer had to be long enough to allow the rotor to catch up. "The trouble is, no matter what software I use, or even if I manually issue pointing commands via serial terminal, the ST2 will stop my rotator too early, resulting in offpointing by about 20 degrees. I am using the same voltage divider that I used on my KCT, so the ST2 is seeing a 0-5v reading from the azimuth rotor POT. The LCD display matches the analog display within a degree, so the ST2 knows correctly where the azimuth rotator is aimed." -- Joe Leikhim Leikhim and Associates Communications Consultants Oviedo, Florida JLeikhim(a)Leikhim.com 407-982-0446 WWW.LEIKHIM.COM
