Students at the Ivy League Brown University are developing an amateur radio satellite EQUiSat that will carry a Xenon Flash Tube (XFT) subsystem to act as an Optical Beacon that should be visible to the unaided eye of observers on Earth.

Using 1.2Ghz

by Todd

Thinking about adding the 1.2Ghz module for my 9100. Prices have dropped a little and units will start become harder to find once production ends. Anybody using this band? I read it's used as a uplink frequency for some satellites. Any input appreciated.ToddAL7PX

Outernet L-Band now carries AMSAT and ARISS weekly bulletins

by Robert Bruninga

The Outernet L-band feed is now carrying a condensed version of the AMSAT and ARISS weekly news files. (Global Geosat coverage except for Northern Alaska)... Receivers are simple: http://aprs.org/outnet.html For ARISS, I manually added a 2 char grid square to each school listed in the school schedule and am asking the outernet folks to parse out that location info and plot a 1200 km footprint on their weather globe showing where people can tune in the ARISS contacts. Then their RTL-SDR dongle could then actually be retuned to hear the contact. Just an idea...

AO-73 status report

by GW1FKY＠aol.com

Just dropping a quick line to report that nothing has been heard ( Transponder or Dashboard ) from AO-73 during the evening passes over here in Europe. I just monitored the latest pass 2000 2015 hrs today Saturday 31st December and could hear nothing. I have posted to the satellite status web pages and other stations had also made reports for this pass and the previous one. I worked AO-73 this morning and it was active but observed very deep fading which I put down to the spin rate. Looking at the graph published the spin rate was now projected to be in the same ball part as when the satellite was launched and activated. Regards Ken GW1FKY

FW: BY70-1

by Jeff Griffin

I was hoping someone with a better memory, or Erich would chime in on this but here goes. I would first add this line to the Doppler.SQF file... BY70-1,436200,145920,FM,FM,Nor,0,0,Voice V/U Then add this line to the subTone.SQF file... BY70-1,67.0,$3F,1 (for an Icom, I'm not sure of other rigs, but you can watch your rigs display to see if the tone is toggled on/off) RTFM Then I download the keps from nasa.all (I was fudging them in for a day) and you should be good to go when you add BY70-1 73 Jeff kb2m -----Original Message----- From: AMSAT-BB [mailto:[email protected]] On Behalf Of Stephen E. Belter Sent: Friday, December 30, 2016 4:01 PM To: Mark Johns; AMSAT-BB Subject: Re: [amsat-bb] BY70-1 Mark, I also get the “E/A-Fehler 105.” error message when I add BY70-1 to a satellite group in SatPC32. Other people don’t have the problem. The error message (in German) means I/O Error 105 in the Delphi programming environment, which I believe is an error writing to a file. What I can’t yet answer is how to fix the problem. We may have a file permissions problem.
