AMSAT: RFI from LED bulbs?
by Robert Bruninga 19 Jul '20

19 Jul '20

I am hearing reports of RFI from these LED bulbs. Not just HF, but also VHF. If you can make any quantitative assessments of such RFI, please let me know. And the amazing thing is that at VHF you will never notice it because RFI is noise power and it is noise power that keeps a squelch CLOSED. Manuallly open the squelch and sometimes RFI will show full scale on the S meter yet not open the squelch. And on my radios, when the squelch is closed, the S meter is inactive and shows 0.

Just curious XW series
by RG 09 Feb '20

09 Feb '20

I have had trouble hearing XW satellites lately.I have a Kenwood ts 2000 and for some reason don't hearing much if anything.I used to hear the beacon pretty loud at least for a few moments and most of the pass okay but not as much.I was wondering if other Op's. are having the same problem.Maybe I need to set up my 706 as a receive radio,It worked good.I dont have any problems with the Kenwood working other modes.It would be nice to use one radio.I run a vertical and realize it's not the best set up but again I haven't had this problem in the past.Just looking for some opinions.Thanks a lot73RichKB1FGC marzo7088(a)yahoo.com

Last minute question! If I am capturing the signal via SDR (GQRX and an RTL-SDR) and piping into FoxTelem, what modulation should I use? Or is this just not possible with HuskySat? --Roy K3RLD

Message to US Educators Amateur Radio on the International Space Station Contact Opportunity Call for Proposals 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 is happy to announce a 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 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. More Information For proposal information and more details such as expectations, proposal guidelines and proposal form, and dates and times of Information Webinars, go to www.ariss.org. Please direct any questions to ariss.us.education(a)gmail.com. About ARISS: Amateur Radio on the International Space Station (ARISS) is a cooperative venture of international amateur radio societies and the space agencies that support the International Space Station (ISS). In the United States, sponsors are the Radio Amateur Satellite Corporation (AMSAT), the American Radio Relay League (ARRL), the ISS National Lab and National Aeronautics and Space Administration (NASA). The primary goal of ARISS is to promote exploration of science, technology, engineering, and mathematics (STEAM) topics by organizing scheduled contacts via amateur radio between crew members aboard the ISS and students in classrooms or public forms. Before and during these radio contacts, students, educators, parents, and communities learn about space, space technologies, and amateur radio.
