Re: [amsat-bb] Preamp source

The problem is hams expect things to cost near nothing and prices never to increase. ARR Gasfet preamps* sold for years at $79.xx yet cost of material are rising. Last I checked they still use the mgf-1302 yet where is one able to find one? The mgf-1302 provides a reliable 0.5 dBNF and about 22 to 25 dB gain. PGA-103+ appears to get 0.6 dB gain with about 15-18 dB gain If you are a small mfr you do not get the volume parts discounts so materials represent 80% or more of your price and return on labor does not justify working. When I built DEMI transverter kits for $100 in labor I made $100/16 = $6.25 per hour. I finally quit as I thought about doing something else in my retirement. WA2ODO has quit the preamp business (age & health). For $85-110 you don't make much for your time once the cost of materials is paid. *non RF switched versions Spend $95 each for two coax relays and add to $79 and see how cheap you can make a switched one for yourself. Yes, some pcb relays can be used if you can figure out how to eliminate inherent inductance/capacitance. RF-sensed switching preamps are still "hot switched": RF arcs across the contacts as the relay closes. Only with a switched preamp under sequenced dc control is the device truly safe. 73, Ed - KL7UW http://www.kl7uw.com Dubus-NA Business mail: dubususa(a)gmail.com

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.

I think the solution for issues like this is the next time Eric does an update to the software, that he changes the Dot X or the letter. In this case that change For now 24 says, should probably have made the software 12.8a since that software iteration also included support for the FT 991 series of radios. His software is really good and his support is incredible, especially in dealing with older radios so I’m not knocking anything. Tom N5HYP
