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.

Kevin, I just played your recording through 1.08p. Recovered 25 frames, which is about what you expect.

Secondary mission ideas
by Andrew Glasbrenner 01 Nov '19

01 Nov '19

I just had a super call with a university program flying a mission using SDRs. We talked about licensing and coordination issues, and discussed ideas for a secondary two-way mission that they want to do. What would you like to see, repeater, transponder, BBS, digital voice, digipeater? Downlink would be on 2m, and would probably be limited to 20-25khz wide. Other ideas? Something new and different? Let's have a civilized discussion about what they could try, as they seem to be an eager and capable bunch. 73, Drew KO4MA

SetPC32 12.8d setup
by Jim White 31 Oct '19

31 Oct '19

Noticing the advert in the Journal and seeing a couple of features that looks useful I downloaded and installed it. Questions: It forced me to uninstall the old version before installing 12.8d. Once installed I had to reconfig everything local like station location, rotor and CAT interfaces, display and operational options... Is that correct or did I miss something that would have made this easier? Jim

by Robert Bankston 31 Oct '19

AMSAT is in the process of redesigning its website and is looking to immediately fill key volunteer member additions to its digital communications team. Available positions include a Webmaster, Content Managers, and an Online Store Co-Manager. Candidates must have experience with Wordpress and be a current AMSAT member. Webmaster: The Webmaster works as an integral member of the AMSAT Digital Communications Team in planning, organizing, implementing, and supporting strategic web technologies. Under minimal supervision, the Webmaster collaborates with the Digital Communications team and AMSAT Development to facilitate ongoing content creation, development of standards, and overall management of AMSAT’s website and member portal. The primary objectives of the Webmaster are to ensure that AMSAT’s digital presence accurately portrays the character, quality and heritage of AMSAT, provide an efficient user experience, and serve to increase recruitment and financial contributions. Web Content Managers: Web Content Managers ensure AMSAT's website and webpages follow best content practices and meet the diverse needs of internal and external customers. As part of the AMSAT Digital Communications Team, Website Content Managers must understand the organizational needs, map them to the end-user needs and work with applicable AMSAT departments to create content strategy and plan for individual webpages. Online Store Co-Manager: The Online Store Co-Manager updates and refreshes the AMSAT Store when new merchandise becomes available, deletes merchandise when no longer available, and updates pricing and shipping information when necessary. Experience in WooCommerce is required. If you want to be a part of the solution in delivering the quality web services AMSAT members deserve, we could sure use your help. Please contact the AMSAT VP of User Services at ke4al (at) yahoo (dot) com. 73, Robert Bankston, KE4AL Vice-President, User Services Radio Amateur Satellite Corporation (AMSAT)
