Theseus Cores PFB Channelizer - update!
by Michelle Thompson 07 Aug '19

07 Aug '19

Good news. The Theseus Cores RFNoC polyphase filter bank channelizer is working. The channel 0 timeouts, which were a vexing problem, seem to be gone thanks to hard work from EJ Kreinar and Phillip Vallance. This particular part is vital for FDMA to TDM type payloads and groundsats. Having a fast, efficient, open source implementation that works in GNU Radio is a big step forward. We are taking the entire setup with us to DEFCON. We are using a linux computer and a USRP. Experiments so far have been on the VHF ham bands and FM broadcast. Next step, move it up to microwave and demonstrate Phase 4 Ground channelization. If you're at DEFCON, come by and see us in ham radio village! There's a license exam session, demonstrations, presentations, and lots of socializing. More soon! -Michelle W5NYV

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 (STEM) 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. For more information, see www.ariss.org.

Budget approach
by Michael 06 Aug '19

06 Aug '19

Ahh geez, here goes someone making sense again! Don't you hate it when they do that?! Michael, W4HIJ It dawned on me that the present culture at AMSAT (and elsewhere) may not support a transparent "resources of the crowd" collaborative approach. (Duh, right? Lol). Here's an entirely different pathway to success: With the goal of getting the AMSAT-DL Phase 3E bird into orbit (as an example), publish the required money and start actively fund raising. To be clear, the required money can't be "millions of dollars" it has to be unambiguous; like $9,242,200. Then, hire a grant writer and a fund-raising organization with the existing AMSAT budget (a small amount of money leverages much more money). If the present AMSAT budget is not sufficient, then determine how much money it will take to hire them and fund-raise for that from friends and family (AMSAT members and enthusiastic non-members). Post a fund raising "thermometer" on AMSAT.org and the world can watch the success grow before their eyes! Ev, W2EV PS: maybe a hybrid approach?? I'd bet that there's someone on this list who's 6-degrees of separation can get to Bezos or Musk to help to reduce even that budget. PPS: I have an idea that could provide incentive to either of these guys, if they could be reached...but "what are the chances, really"?

Help with Spid rotor setup on Satpc32
by Richard Gussow 06 Aug '19

06 Aug '19

Hi everyone, I was wondering if someone can help me with an issue I am having with setting up Satpc32 and my Spid Ras rotor. SatPC32 asks for a parallel port of 1-4 in the set up menu, while the Spid Ras controller set up a serial port (com port 8 in my case). How do I reconcile the two? Thanks, Rich4Z1JJ

Is there any interest...
by Ev Tupis 06 Aug '19

06 Aug '19

... in pursuing a more open project plan that would make it easier for those with personal skill, resources or contacts to more directly contribute to a launch? Even a private note to say, "yes, I think we'll be looking into that" would be nice. I'm unsure how to digest the silence. :-) Ev, W2EV

TLEdoctor program to check for preliminary TLE data
by Jarda 06 Aug '19

06 Aug '19

The program can easily detect and fix the TLE preliminary data errors for working in satellite programs after launching the satellite in orbit The original version of the program released before launching Fox-1D works in Windows-7 and higher. Version that works in Windows XP is now added. The program name for Win-XP changes to TLEdoctor. Both programs can be downloaded at http://oscar.ok2gz.eu/fox1d.php 73 Jarda ok2gz --- This email has been checked for viruses by Avast antivirus software. https://www.avast.com/antivirus

FUNcube-1/AO73 Operations - Satellite entering continous sunlight mode
by Jim Heck 06 Aug '19

06 Aug '19

Hi Folks, FUNCube-1/AO-73 is due to enter continuous sunlight in a few days time and the operations team have decided to set the satellite to full time education mode (full power beacon with NO transponder, no eclipse auto switching). One of the effects of this is that the temperature of the satellite will increase. This will allow us to follow the effects of continuous sunlight more easily, and also in theory should keep the satellite cooler (more energy radiated from the structure as RF) We predict that the satellite will start experiencing eclipses again on approximately 7 May 2020. We may put the satellite back into transponder mode while it is in continuous sunlight, and if we plan to do this we will make an announcement here 73 Jim G3WGM and the FUNcube team
