AMSAT: RFI from LED bulbs?

by Robert Bruninga

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.

Re: [amsat-bb] IC-9700 & FoxTelem 1.08p

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

Secondary mission ideas

by Andrew Glasbrenner

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

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
