I received another email from Dr. Kelso this morning asking if I would like to have the BY70-1 TLEs also placed in the Amateur Radio listing as well. I told him that if he could do so, that would be great. I'm sure it will be taken care of later today. 73, Mac / AE5PH -------------------------------------------- On Mon, 1/30/17, Mac A.

Celestrak BY70-1 keps

by mac cody

All, I received a nice reply from Dr. Kelso to the email I sent him yesterday. He has added the BY70-1 TLEs to the CubeSats listing (http://www.celestrak.com/NORAD/elements/cubesat.txt). This file should be available to most software tracking applications (at least is is available as a source in AmsatDroid Free) and will be updated more frequently compared to the BY70-1 TLEs provided through AMSAT. 73, Mac Cody / AE5PH

14000+ LoTW sat contacts uploaded

by Jeff

I finally had the time (it took mea good part of 4 days) to massage my old sat contacts and upload then to LoTW. I sent over 14,000 sat contacts from 1997 to April 2013 to LoTW. I now keep separate logs for my 3 residences. Here is what the results are so far from my main NJ log.... Sat DXCC 19 of 96 QSO’s confirmed, WAS 35 of 50 states confirmed , VUCC 114 of 569 grid’s confirmed . A pretty dismal QSL LoTW return if you ask me. More should show up when the rest of you old sat op’s upload your sat contacts to LoTW. For example I have 4 sat contacts with AK, no QSL. I will now have to go through my 3,000+ QSL cards to check for SAT contacts. I went through them last year for HF and only added 3 QSL records to my HF total’s, now 289 of 330. So I’m not feeling optimistic about getting the 77 SAT QSL’s I need! Also, Besides the logging fields mismatched with LoTW that I had to fix, there also was a big almost 3 year long area of my log that had been corrupted by LUX-LOG the logging s/w I was using at the time, I was unaware that my log was corrupted until it was too late. I recovered some of the QSO’s but there are thousands lost, including ALL of my RS-10 contacts, most of my RS-15, RS-12, RS13, and some of my AO-10, and AO-40. I now wonder if any of those lost HEO contacts would of put me over 100 SAT DXCC. Very sad.... 73 Jeff kb2m

interested in India's Rocket Provider Launch by PSLV rocket.

by Tanan Rangseeprom

Dear All of AMSAT India The delegate of Radio Amateur Society of Thailand under the patronage of His Majesty the King (RAST) has provided us with AMSAT India contact information in conjunction with our plans to launch a CUBESAT amateur radio satellite in the near future. Perhaps, I should begin with a brief introduction and an outline of our project to launch Thailand's first amateur radio satellite. RAST is the national non-profit society for amateur radio enthusiasts in Thailand which qualifies as a charitable entity pursuant to a Thai Ministry of Finance declaration while the society is also a member of the International Amateur Radio Union. RAST has joined three Thai institutes of technology to support the first Joint Academy Intelligent Satellites for Amateur Radio of Thailand (JAISAT-1) project which has received funding from the Broadcasting and Telecommunications Research and Development Fund for the Public Interest (BTFP), which is under Thailand's regulator, the National Broadcasting and Telecommunications Commission (NBTC). The three academic institutes are all in the King Mongkut's Institute of Technology group, being King Mongkut's University of Technology of North Bangkok (KMUT-NB), King Mongkut's University of Technology Thonburi (KMUTT) and King Mongkut's Institute of Technology Ladkrabang (KMITL). In a meeting on July 22, 2015 the NBTC committee approved state funding for RAST's JAISAT-1 project over a two-year period: 2016-2017. In my capacity as the JAISAT-1 project leader in charge of building the satellite along with a technical team from RAST, I am writing to you with a humble request for assistance. We currently face the challenge of finding an appropriate rocket for the launch of the CUBESAT satellite, one that will be within our limited budget and we are interested in India's Polar Satellite Launch Vehicle or PSLV rocket. In addition to our JAISAT-1 satellite there are two other CUBESAT projects that have received funding in Thailand, including a KNACKSAT satellite to be built by the King Mongkut Institute of Technology of North Bangkok (KMUT-NB) and a SPACEBOX satellite to be built by the King Mongkut University of Technology Thon Buri (KMUTT) as part of a project to "Explore the World" using remote sensing with these satellites being equipped with cameras. But RAST 's JAISAT-1 satellite will be for amateur radio communications for which we are designing and building a linear transponder ourselves in Thailand and we would like to seek your recommendations to help us to get in touch with someone who can provide a PSLV rocket to launch the CUBESAT satellite at a special rate one that we will be able to afford. We would very much appreciate any assistance, advice or recommendations that you can make for us to help our project achieve all its goals. With deep respect. Sincerely, Tanan Rangseeprom, HS1JAN JAISAT-1 Project Leader Manager Radio Amateur Society of Thailand Under the royal patronage of His Majesty the King

THANKS Re: Where did the TLEs go for BY70-1?

by Todd Deckard

Greetings Mac, Thanks for this! The AMSAT ftp site isn't updated frequently enough for the deteriorating orbit and a single precision PLAN13 implementation on the ATmega1280. As an example here's the CELESTRAK output: BY70-1 1 41909U 16083C 17029.24424671 .00506735 24288-5 70240-3 0 9991 2 41909 97.5768 109.7306 0160558 244.2616 114.2002 15.85900257 5044 Here's the AMSAT record sampled from the same time. BY70-1 1 41909U 16083C 17026.84471594 .00329730 24344-5 49404-3 0 9999 2 41909 97.5781 107.0760 0167800 253.3870 105.1424 15.83446051 4663 As expected, atmospheric drag has the largest effect on the semi-major axis, eccentricity, and argument of perigee. Alas it won't be long now. Still haven't gotten a confirmed QSO! Best Todd >Mac A.

NJ7H/VE7/VE8 Antenna Cables Repaired

by John Papay

Many have been working NJ7H/VE8 and /VE7 as he travels through rare grids in the Northwest Territories and other Provinces. Unfortunately he started having problems with his antenna cables and that caused him to start using his whip on the car for transmit and limiting operations to FO-29 passes. Today the problems were fixed, if only temporarily, all due to the help of a Canadian Ham who is not a satellite operator. Tim Repas, VE7XIX, who lives in Taylor BC, near Fort St. John met up with Gabe earlier today and helped him get his cables working again. This is yet another story of hams helping other hams they have never met before. And the story probably won't find its way into QST magazine either. So I would encourage all of us who have been working Gabe and those who just might be readers on the board, to send an email of appreciation to Tim at his QRZ address. It just might make his day; he certainly helped make ours! 73, John K8YSE --- This email has been checked for viruses by Avast antivirus software. https://www.avast.com/antivirus

Re-entry predictions for BY70-1

by Todd Deckard

Greetings Joe! space-track.org lists the decay epoch as 2017-02-22 0:00:00 -- note this is not strictly the re-entry time but perhaps gives us an approximate window? I do not understand the material very well. It appears for large objects they will calculate a time-and-impact prediction as things become more certain but perhaps poor Bayi-Kepu-Weixing-1 may not rate as it doesn't pose a hazard. I don't even know if it would be visible during re-entry given the speed? >When will we have a closer idea of when it may re-enter? > >It would be neat to try to catch it on video. > >Joe WB9SBD
