EQUiSat Optical Beacon CubeSat
by Trevor . 17 Oct '18

17 Oct '18

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. See http://www.uk.amsat.org/?p=10635 73 Trevor M5AKA AMSAK-UK http://www.amsat-uk.org/ ----

Using 1.2Ghz
by Todd 04 Apr '18

04 Apr '18

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 17 Mar '18

17 Mar '18

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...

by Nico Janssen 18 Feb '17

18 Feb '17

All, If the current trend continues, BY70-1 may be expected to decay and burn up in the atmosphere by mid-February. The apogee of the satellite has decreased from initially 520 km to now 426 km and the perigee has decreased from initially 216 km to now 208 km. 73, Nico PA0DLO

SAT 32/IC910 problem
by James Brown 31 Jan '17

31 Jan '17

When AO85 is selected the ic 910 does not select fm. I have also noted that AO 85 seams to be off frequency from 145980/435180 and when I change SAT 32 pulls it back to what it wants.How should I correct this. Should I change the Doppler sqf to some other frequency? Jim KI6WJ

foxtelem error
by kevin schuchmann 31 Jan '17

31 Jan '17

Hi, Does anyone else get a error message occasionally when stopping and starting the decode on foxtelem? I have seen the following error on multiple pc's javax.sound.sampled.LineUnavailableException:line with format PCM_SIGNED 48000.0Hz, 16 bit,stereo, 4 bytes/frame, little-endian not supported Makes it look like the audio line is unavailable, but doing nothing more than closing the program and restarting it clears the error. Thanks Kevin wa6fwf
