Aug 19-21 Thank you so much for being with us during the Dayton Hamvention. We had over 30,000 unique hams follow us the 5 days and in about 100 countries. We hoped you enjoyed the broadcast. We will be broadcasting the Huntsville, AL hamfest Aug 20-21. This is a large hamfest that pulls many people from not only the S.E. U.S. but also across the country. We will have prizes again for our viewers. This is a great inside facility and we will have perfect connectivity so will be able to stream great quality video. We will also be able to move around and show you everything plus lots of interviews. Watch for us on Aug 19 (Friday) starting around 9:00 am central time 1400 UTC and you may see us drive the 3 hours and then as we set up our equipment on Friday afternoon. Log into the chat room and talk to others around the world or to the W5KUB staff directly. The website is the same http://w5kub.com Please help pass this information around to other hams that you know. Also please register for the chat room if you have not done so. It takes only about 1 minute to register. Just pick your name, and a password, and then enter your email. You will receive an email (instantly) with a verification code. That will complete your new account and register you. By registering it makes you eligible for our prizes. Thanks and 73, Tom W5KUB Some of the prizes that we are giving out on this broadcast are: Grand prize announcement Yaesu FT-950, G5RV antennas, Yaesu Handi-talkie, LDG auto antenna tuner, baluns, Rollable Solar charger, KPC-3 plus packet communicator, ground radial staple pins, ARRL handbook, Communication Speakers, yearly subscriptions to CQ, CQVHF, and Poplar Communications, Tentec Microphone, ferrites, and QSL cards. http://w5kub.com or http://wa5kub.com -- 73 de JoAnne K9JKM k9jkm(a)amsat.org Editor, AMSAT News Service

Re: Official Word for 440 Antenna
by Clint Bradford 18 Aug '11

18 Aug '11

>> ... What is the official AMSAT/ARISSat1 team finding on the ARISSat-1 70cm quarter-wave receive antenna on the bottom of the satellite? Not the "official" word by any means ... but the 440 whip was not there when deployed. SO ... we are working with a 1.5" antenna instead of a 6.5" antenna. But - All modes of ARISSat-1 are operational - FM Downlink 145.950 - Operational Linear Transponder U/V - Operational CW Beacon 145.919 - Operational VHF SSB BPSK-1000 - Operational Clint, K6LCS http://tinyurl.com/ARISSAT1-STATUS

AO-51 updates Re: Re: a051 frequencies
by Mark L. Hammond 18 Aug '11

18 Aug '11

Hi John, Just yesterday I was trying to find time to type out a few AO-51 updates; this will be brief, but hopefully informative to those on the list. AO-51 is currently transmitting on 435.150 FM (LHCP) and using a 145.880 FM uplink. We expect the keep this configuration "until futher notice." The power level is just under 1 watt (about 980 mW). The last restart of the satellite was something like 18 days ago!! This stretch of uninterrupted service has been great, and really just "good luck." Because of the failure of one cell of the six-cell battery, the bird remains in "limp mode." By that I mean we are limited to simple commanding and configurations, because a software upload/execution has proven impossible due to the lower voltages resulting from the one dead cell. At least we can set power levels manually, change uplinks/downlinks, etc. But there is no telemetry collection/storage, no BBS, etc. There is a second cell in the battery that looks "sick." We have no idea if it will be the next cell to go (probable though), nor what the result will be (if we lose another cell, "limp mode" probably will no longer be an option, and the mission might be considered over.). It might last a few days, a few months, or who knows...a few years? (doubtful). The current scenario of AO-51 is one reason we need to keep moving AMSAT and satellite development/building/launching moving forward!! We have learned a lot already with ARISSat-1, and FOX looks promising. AMSAT needs the support of its users now more than ever... A little speculation--recently we have been looked upon kindly by the "battery shorting gods." It looks like AO-51's dead cell has failed closed/shorted--which is good for this bird; and it looks like maybe ARISSat-1's battery might be failing/have failed in an "open" fashion--which is good for this bird! 73!

a051 frequencies
by Joe 18 Aug '11

18 Aug '11

I will be trying to work ao-51 during the ILLW this weekend (20-21Aug). I havent operated satellites since ao40, which is a little while ago... I will be using the usual an arrow antenna and ft60r. I am having problems finding the frequencies to tx and rx on. It seems that there have been some changes made and different sites give me different frequencies I should be using. I think the Tx is 145.880. I think the Rx frequency is 435.500. Can anyone please give me a definitive answer? I have only just got the antenna and radio working as a unit in the last 24 hours. I will be operating from Cape Schanck, just south of Melbourne Australia, under the callsign VK3EMF. Thanks Joe VK3BKI

Edusat and Kentucky
by charlie Cantrill 18 Aug '11

18 Aug '11

Looks like Edusat will be partially controlled here from the U.S., right down the road in Kentucky. This is Dr. Ben Malphrus KJ4HJV of the Morehead Space Science program.Sounds like they are preparing to test a Femtosat deployment system. I should point out, this is where Bob Twiggs is currently teaching. http://www.youtube.com/watch?v=ljnK2LVi9hw Charlie Cantrill KI4RDT

ARISSat clock and TLM records
by Richard Ferryman 18 Aug '11

18 Aug '11

Now that the ARISSat clock seems to be resetting on a regular basis I am wondering how this will affect the TLM and Kursk data which I am capturing and uploading. It seems to me that the only way of collating the data is by the time of upload to telemetry.arissattlm.org Dick G4BBH

ISS School QSO
by James Luhn 18 Aug '11

18 Aug '11

I am portable in Alabama and do not have access to my past e-mail. A post a day or so ago had information about a school that had a scheduled QSO with the ISS on August 18. I am at a camp in Alabama and would love to at least monitor the conversation coming from the ISS. Would someone repost the info or contact me directly with a copy of the post. 73, James W5AOO luhn(a)wt.net
