Preamp source
by Jim White 07 Nov '19

My 22 year old Landwehr VHF preamp finally gave it up. I'd appreciate leads on high quality mast mounted preamps for VHF. AR2 doesn't answer their phone and some uni's I work with say it takes days to get a call back then AR2 didn't have the one they wanted and said they would not be making any more. And SSB USA's recording says they are only available sporadically. Looks like I can order direct from SSB in Germany so that's an option. Are there any low noise RF switched manufacturers/vendors in the U.S. these days? Where are folks getting preamps these days? Jim

Turns out HRO has some SSB units in stock including the SP-200 I wanted. So I've ordered one there. I hope HRO continues to stock the SSB units. The Minikets a couple folks suggested looks like a great option as well, especially if I was going to expand the EME array and put a preamp at the feed of each antenna. Thanks for all the suggestions.

Has anyone used a Mirage product since they became part of MFJ? If so, with what results? P.S. I talked to Jay at ARR just yesterday and he says they will not be making any mast mounted preamps. I didn't ask about other models. 73, Frank FRANK KARNAUSKAS, N1UW 3670 E. KINGLER SPRING PL.

D-Star Interference to XW-2A Downlink
by Hasan al-Basri 07 Nov '19

07 Nov '19

There is a repeater on 145.670 (D-Star) in the Dallas area https://w5fc.org/tag/fsq/ It makes using XW-2A nearly impossible as it is right in the passband. Who in the world thought it was a good idea to put a D-STAR repeater (simplex) in the middle of a satellite downlink passband? Does this comply with any existing ARRL Band Plan, on other words is this a shared resource with D-Star? If so, I guess it's just tough luck and live with it. If not, perhaps someone from AMSAT can have a word with the Trustee? 73, N0AN Hasan

Message to US Educators Amateur Radio on the International Space Station Contact Opportunity Call for Proposals Current Proposal Window is October 1, 2019 to November 30, 2019 Upcoming Proposal Window is February 1, 2020 to March 31, 2020 The Amateur Radio on the International Space Station (ARISS) Program is seeking formal and informal education institutions and organizations, individually or working together, to host an Amateur Radio contact with a crew member on board the ISS. ARISS anticipates that the contact for proposals submitted in the proposal window now open would be held between July 1, 2020 and December 31, 2020. ARISS is happy to announce a second proposal window will open February 1, 2020 for contacts that would be held between January 1, 2021 and June 30, 2021. Crew scheduling and ISS orbits will determine the exact contact dates. To maximize these radio contact opportunities, ARISS is looking for organizations that will draw large numbers of participants and integrate the contact into a well-developed education plan. The deadline to submit proposals for contacts between July 1, 2020 and December 31, 2020 is November 30, 2019. The proposal window for contacts between January 1, 2021 and June 30, 2021 will open on February 1, 2020 and close on March 31, 2020. Proposal information and documents can be found at www.ariss.org. Two ARISS Introductory Webinar sessions will be held on November 7, 2019. The first is at 6:00 PM ET and the second is at 9:00 PM ET. The same material will be covered during both sessions, so choose the session that best fits your schedule. The Eventbrite link to sign up is https://ariss-introductory-webinar-fall-2019.eventbrite.com . The Opportunity Crew members aboard the International Space Station will participate in scheduled Amateur Radio contacts. These radio contacts are approximately 10 minutes in length and allow students to interact with the astronauts through a question-and-answer session. An ARISS contact is a voice-only communication opportunity via Amateur Radio between astronauts and cosmonauts aboard the space station and classrooms and communities. ARISS contacts afford education audiences the opportunity to learn firsthand from astronauts what it is like to live and work in space and to learn about space research conducted on the ISS. Students also will have an opportunity to learn about satellite communication, wireless technology, and radio science. Because of the nature of human spaceflight and the complexity of scheduling activities aboard the ISS, organizations must demonstrate flexibility to accommodate changes in dates and times of the radio contact. Amateur Radio organizations around the world with the support of NASA and space agencies in Russia, Canada, Japan and Europe present educational organizations with this opportunity. The ham radio organizations' volunteer efforts provide the equipment and operational support to enable communication between crew on the ISS and students around the world using Amateur Radio.
