I find myself calling in the pile on HF on occasion (I'm working on helping my HF signal this week). Getting through on satellite is much easier and faster. Back when we had AO-13 and AO-10 we also had AO-21 (FM Bird). The FM bird was pretty much the same in those days. You are correct it is a lot like contesting. I actually enjoy the quick exchange format of the FM birds. I really don't understand why other folks feel the need to complain about it-- if you like it join us -- if it's not your cup of tea, there are many other facets of Ham radio available. 73, Joe kk0sd YEAH!

Hi Bill and Dinesh, I was a part of the ISRO team that conducted the Thermal Vacuum, vibration and other environmental tests for both Jugnu and SRMSat. I was able to receive the signals from both the satellites, while they were here in my cetre during the above mentioned test. I even used Funcube Dongle to receive and decode the telemetry CW data. Frequencies: SRMSat: Payload down link and CW Beacon on the same frequency - 437.425 (10dbm) Jugnu: CW Beacon - 437.275 (17dbm) Pay load - 437.505 73 de Mani, VU2WMY Secretary & Station-In-Charge Upagrah Amateur Radio Club VU2URC ISRO Satellite Centre HAL Airport Road, Bangalore-560 017.

What a shame this pass, just a few QSOs can be finished because all calling others without give a chance the complete the current QSO. What we need to fix that?.... I will wait for a better pass.

Sanjay Srikanth Nekkanti, AB3OE, confirmed that SRMSAT has passed all the required tests and is now at ISRO's spaceport, Sriharikota, ready for the Oct 12th launch. The downlink and ground station details for SRMSAT can be found on AB3OE's page here: http://srmuniv.academia.edu/SSN/Papers/149827/Ground_Station_Design_for_a_N… At the moment, I have no information about JUGNU.

using 736 with CAT Control/USB
by Tim Goodrich 03 Oct '11

03 Oct '11

Hi all, I just bought a Yaesu 736 and am interested in doing some work on the satellites with SatPC. Can you tell me what most people use to connect the 736 to a USB port to do CAT control? I know there's an issue with TTL levels and I also know not to use the prolific chip set. Thanks! Tim K6TW

Students - Name That Spacecraft!
by Clint Bradford 03 Oct '11

03 Oct '11

NASA INVITES STUDENTS TO NAME MOON-BOUND SPACECRAFT WASHINGTON -- NASA has a class assignment for U.S. students: help the agency give the twin spacecraft headed to orbit around the moon new names. The naming contest is open to students in kindergarten through 12th grade at schools in the United States. Entries must be submitted by teachers using an online entry form. Length of submissions can range from a short paragraph to a 500-word essay. The entry deadline is Nov. 11. NASA's solar-powered Gravity Recovery And Interior Laboratory (GRAIL)-A and GRAIL-B spacecraft lifted off from Cape Canaveral Air Force Station, Fla. on Sept. 10 to begin a three-and-a-half-month journey to the moon. GRAIL will create a gravity map of the moon using two spacecraft that orbit at very precise distances. The mission will enable scientists to learn about the moon's internal structure and composition, and give scientists a better understanding of its origin. Accurate knowledge of the moon's gravity also could be used to help choose future landing sites. "A NASA mission to the moon is one of the reasons why I am a scientist today," said GRAIL Principal Investigator Maria Zuber from the Massachusetts Institute of Technology (MIT) in Cambridge. "My hope is that GRAIL motivates young people today towards careers in science, math and technology. Getting involved with naming our two GRAIL spacecraft could inspire their interest not only in space exploration but in the sciences, and that's a good thing." Zuber and former astronaut Sally Ride of Sally Ride Science in San Diego will chair the final round of judging. Sally Ride Science is the lead for GRAIL's MoonKAM program, which enables students to task cameras aboard the two GRAIL spacecraft to take close-up views of the lunar surface. NASA's Jet Propulsion Laboratory in Pasadena, Calif., manages the GRAIL mission. GRAIL is part of the Discovery Program managed at NASA's Marshall Space Flight Center in Huntsville, Ala. Lockheed Martin Space Systems in Denver built the spacecraft. For contest rules and more information, visit: http://grail.nasa.gov/contest The public can email questions to: grailcontest(a)jpl.nasa.gov For more information about GRAIL, visit: http://www.nasa.gov/grail For more information about MoonKAM, visit: https://moonkam.ucsd.edu/ -end- Clint Bradford clintbradford(a)mac.com

ARRL Spectrum Defense Matters newletter
by Trevor . 03 Oct '11

03 Oct '11

There are no Global Primary Amateur and Amateur Satellite Service allocations between 146 MHz and 24 GHz. Access to spectrum suitable for weak signal work in the 146-3500 MHz region is crucial for the Amateur Satellite Service. It is encouraging to read on page 2 of the September issue of the ARRL Spectrum Defense Matters newletter about the formation of the IARU Spectrum Futures Committee. The aim of the Committee is to develop strategies for retaining access to bands above 148 MHz for the amateur and amateur-satellite services globally. In the past it seemed that IARU was only interested in HF and ignored the UHF and Microwave spectrum, so the formation of this committee seems a step in the right direction.

operating FM Sats/phonetics
by Ellis Foley 03 Oct '11

03 Oct '11

Return Mail to wa1rks(a)yahoo.com I agree whole heartily with the use of phonetics any time ! anywhere!. lots of old ears out there, (mine included) but not just that, conditions on any medium is always subject to degradation,Faraday,phaseshift,doppler,you name it-It can happen.especially with the "E" sounding letters,namely T,Z,E,B,C,V to name a few. I can't count the times I called for another ID to get one of them that I missed the first time around. Even under ideal conditions, not everyone's grammar and .diction is understandable. My other pet peeve is the use of improper phonetics, The world has one set, use them only, I don't like hearing "Zebra, Zink,Zorch!!" for Zulu. A few Good operatiing practices makes for an enjoyable Qso, not just a "zip it lip it,get on with it,and wheres the next guy?". My two cents worth.:-)Thanks 73 Gud dx ! Happy Dx Hunting !. de Ellis Wa1rks

ARISSat-1 Contact Experiment via Trqnsponder
by Farrell Winder 03 Oct '11

03 Oct '11

In follow up of my previous post request, ARISSAT-1 did not activate for my location in Cincinnati until there was only about 40 seconds left in the pass which started at 13:44Z AOS. However, I did hear my CW signals with slight fading. Due to the eclipse delay and orbit it does not appear favorable at my location for further experiments via ARISSat-1 transponder for several days. . Thanks to anyone who might have tuned for my signal. Farrell Winder, W8ZCF, Cincinnati, Ohio
