Instead of building eggbeaters, pick up a few of these: http://www.mfjenterprises.com/Product.php?productid=MFJ-261 You'll also need a pair of these: https://www.amazon.com/Coaxial-Cable-Female-SO239-PL259/dp/B00KQHH7VC Hook those into your baofengs and you'll be just as effective on the Satellites as you would with some homemade 'beaters.

(What a mess was that pass) !! FYI, it's kind of hard to figure out how to log a contact that was giving a location as "67-68 line". I understand the concept of brevity, but not everyone is a mind reader Can someone fill in the grid letters from N7AGF's location, pls ? 73, Ted K7TRK

Re: [amsat-bb] Karl Janskey call sign
by Edward R Cole 03 May '19

https://www.astroleague.org/content/grote-reber-radio-astronomer As you can see W9GFZ was the callsign of another great RA pioneer, Grote Reber. Jansky's work came earlier as a engineer attempting to find the source of radio noise and stumbled onto the source as celestial. https://www.nrao.edu/whatisra/hist_jansky.shtml I see no reference to being a ham. Both antenna are on exhibit at entrance to GB (been there several times with SARA). Also visited VLA in spring of 1974 when it was under construction and may have been the first visiting engineer to get a tour (unofficial). I was working at Goldstone (NASA). In 1997 I was with the last tour to see the "Big Ear" telescope of Dr. John Kraus http://www.bigear.org/ 73, Ed - KL7UW Date: Thu, 2 May 2019 10:48:59 -0400 From: Jim JIpping <jhjipping(a)gmail.com> To: Kevin M <n4ufo(a)yahoo.com>, amsat-bb(a)amsat.org Subject: Re: [amsat-bb] Karl Janskey call sign Message-ID: <33f4b650-cfed-f0b8-d522-289534d70a63(a)gmail.com> Content-Type: text/plain; charset=utf-8; format=flowed Thanks, Kevin!?? You absolutely correct,? W9GFZ is the call and the club is in Socorro, NM.? When I was at Green Bank for the dedication of the GBT, I was on the understanding the group at GB had the call. BUT the NRAO is more than just GB.? I had a very nice personal guided tour of Socorro by one of the hams on staff there.? It was arranged by a good friend, Dr. Paul Vanden Bout, the then director of the NRAO. Paul and I both graduated from Calvin College in Grand Rapids, MI. I remember well the whole day I spent on site at the VLA. I was allowed to take several high school student to GB to use the 40 ft instructional telescope and learn about radio astronomy. We stayed in the dorm and had three activity filled days at the facility. I did this three years running.? What an experience! That was REAL science! As a physics teacher, I have to say that my experience at Green Bank and several? tours of observatories across the US I was privileged to take completely changed my perception of science and the scientific method. Any way, thanks for the correction.? I noticed the typo and was preparing to correct it? and, then, saw your post Jim Jipping, W8MRR, AMSAT 5512 73, Ed - KL7UW http://www.kl7uw.com Dubus-NA Business mail: dubususa(a)gmail.com

The main page for Applying to Host a Scheduled Contact may be found at http://www.ariss.org/apply-to-host-an-ariss-contact.html ARISS Contact Applications (United States) The ARISS webpage is at http://www.ariss.org/ Note that there are links to other ARISS websites from this site. International Space Station Astronauts are Calling CQ Students ARISS-US program’s education proposal window is open April 1 - May 15, 2019 March 24, 2019: The Amateur Radio on the International Space Station (ARISS) program is seeking proposals beginning April 1, 2019, from US schools, museums, science centers and community youth organizations (working individually or together) to host radio contacts with an orbiting crew member aboard the International Space Station (ISS) between January 1, 2020 and June 30, 2020. Each year, ARISS provides tens of thousands of students with learning opportunities about space technologies, communications, and much more through the exploration of Amateur Radio and space. The ARISS program connects students to astronauts on the ISS through a partnership between NASA, the Radio Amateur Satellite Corporation, the American Radio Relay League, other Amateur Radio global organizations and the worldwide space agencies. The program’s goal is to inspire students to pursue interests and careers in science, technology, engineering, and mathematics (STEM) and in Amateur Radio. Educators report regularly that student participation in the ARISS program stimulates interest in STEM subjects and STEM careers. One educator wrote, “Many of the middle school students who took part in and attended the ARISS contact have selected science courses in high school as a result of that contact.” Educators are setting up ham radio clubs in schools and learning centers because of students’ interest. ARISS is looking for organizations that will draw large numbers of participants and integrate the contact into a well-developed, exciting education plan. Students can learn about satellite communications, wireless technology, science research conducted on the ISS, radio science, and other STEM subjects. Students learn to use Amateur Radio to talk directly to an astronaut and ask their STEM-related questions. ARISS will help educational organizations locate Amateur Radio groups who can assist with equipment for a once-in-a-lifetime opportunity for students. The proposal window opens April 1, 2019 and the proposal deadline is May 15, 2019. For proposal guidelines and forms and more details, go to: http://ariss-proposal-webinar-spring-2019.eventbrite.com Proposal webinars for guidance and getting questions answered will be offered April 11, 2019 at 7 pm Eastern Time and April 16, 2019 at 9 pm Eastern Time.

Umesh, I don't necessarily think that the people who step on us are necessarily simplex guys. Simplex people can hear when you are speaking. It is sad, but I believe it is very rude hams who believe they are more important. More like contesters who will step on anybody to get their contact. 73Brad KC9UQR In a message dated 5/1/2019 11:06:16 PM Central Standard Time, amsat-bb-request(a)amsat.org writes: It was one of the busiest passes I have encountered and it isn't even Saturday yet !! Heard many new calls and tried calling back but got stepped on, probably from guys operating simplex, finally got N7AGF when the bird was almost LOS.?

Yaesu FT-757GX Mark I

Hello Everyone, I have a Yaesu FT-757GX Mark I that I would like to interface with some control software. I have a brand new USB to 3 Pin control plug. I found DXLab software, but it is a bit overwhelming. Is there another software package that someone can recommend since Ham Radio Deluxe does not support this model? 73's KF6FES Brian
