Has anyone heard TRITON-1? I listened for two passes today and haven't heard any downlink signals. Dave Marthouse N2AAM dmarthouse(a)gmail.com

DragonSat - new test (SSB)
by Robert Bruninga 09 Dec '13

09 Dec '13

> Nothing heard from DragonSat on 145.870. (9600 baud AX.25) A crude test of a Dragonsat model with the antenna un-released was still radiating on the order of 26 to 36 dB down. >From now on, instead of FM, we are going to listen with an SSB receiver and see if we hear the 30 second chirps. Listening on SSB should improve our listening sensitivity 20 dB or so, plus an added 10 dB on direct overhead passes might make it detectible if the only problem is antenna deployment. Should be a less than one second burst every 30 seconds on 145.870. Should be near the pass times of CAPE... Bob, WB4APR

Annuncement scheduled for Ham Radio Juno Flyby eperiment
by andy thomas 09 Dec '13

09 Dec '13

Following is from the American Geophyiscal Union website (time is San Franscisco time) http://fallmeeting.agu.org/2013/media-center/press-conferences/#juno Science from Juno’s Earth Flyby Tuesday, 10 December 10:30 a.m. In October, the Jupiter-bound Juno spacecraft did a flyby of Earth before its long journey. The Juno team presents a low-resolution Earth flyby video as well as data acquired by the spacecraft as it zipped past the home planet. Team members will also discuss results from the mission’s outreach campaign inviting amateur radio operators to “Say Hi to Juno” as the spacecraft passed, and the scientific goals for the mission once it reaches Jupiter. Participants: Scott Bolton, Juno principal investigator, Southwest Research Institute, San Antonio, Texas, USA; John Joergensen, Juno star-camera team lead, Danish Technical University, Copenhagen, Denmark; Bill Kurth, co-investigator for the Juno Waves Investigation, University of Iowa, Iowa City, Iowa, USA. Sessions: SM21E, SM33B 73 de andy g0sfj

Negative Results For TrailBlazer & DragonSat
by Armando Mercado 09 Dec '13

09 Dec '13

Hello, Listened for Trailblazer (possible 39382) during this morning's pass. Heard a few CW characters on 437.428 at 1432 UTC, which could have been AAuSat-3, but no 1200 AFSK. Nothing heard from DragonSat on 145.870. DO-64 was on and loud near the end of the 2013-064 "train" pass. 73 Armando N8IGJ

Power output for using AO-73 transponder
by Paul Stoetzer 09 Dec '13

09 Dec '13

FYI - In a sidebar on their website, AMSAT-UK requests that stations limit power output to 25W EIRP for using the AO-73's transponder. "FUNcube-1 / AO-73 Radio Communications Subsystem • 145.935 MHz BPSK Telemetry 30 or 300 mW • Inverting SSB/CW transponder 300 mW PEP - 435.150 – 435.130 MHz Uplink LSB - 145.950 – 145.970 MHz Downlink USB Educational Telemetry beacon is 300 mW during day and 30 mW at night. Transponder is only active during night passes. Please use a maximium uplink power of 5 watts to a 7 dBi gain antenna (25 w EIRP). Lower power will also work well. If adjusting for Doppler shift manually try tuning the uplink frequency while transmitting to keep the downlink constant." http://amsat-uk.org/ 73, Paul Stoetzer, N8HM Washington, DC

AO 73
by Rich/wa4bue 09 Dec '13

Sorry David for my mistake. Are my Keps okay? ----- Original Message ----- Hi Richard. If you could make the subject something like AO-73 it helps your message get stored in the correct place in the AMSAT archives which are stored in thread and date order. AO-73 will typically have +- 9 kHz of Doppler on 70 cms and +/- 3 kHz on 2m. Thanks David -----Original Message----- From: Rich/wa4bue <richard.siff(a)verizon.net> To: amsat-bb <amsat-bb(a)amsat.org> Sent: Mon, 9 Dec 2013 11:11 Subject: [amsat-bb] Re: Auburn sat Hi all, Another question AO 73 I made my first contact on AO 73 this weekend with KB2M. I read on the BB that the frequency was about 10 Khz higher for the uplink and that the linear transponder wss not stable yet. I did not expect the Doppler to be shifting as much as it was on both the the QSO freqs and the Telem freqs. Maybe I had the wrong keps in! The Keps we installed were dated November 23rd. Thank you for your help. R W4BUE / K4AMG _______________________________________________ Sent via AMSAT-BB(a)amsat.org. Opinions expressed are those of the author. Not an AMSAT-NA member?

Sat-Antennas ...?
by Jens Spiess 08 Dec '13

08 Dec '13

Hello... if somebody has experiences for the satellite radio over present, functioning amateur radio satellites with the following antennas: EB-144 M2 und EB-432 M2 (following the Link) ??? Dignity these antennas is sufficient around more or less adequate company to be able to do over the satellites available still nowadays, without rotors, however, with preamplifiers... or would you advise me against the investment in these antennas from the start??? Use here an IC910H. I have worked during earlier years very well with the MASPRO antennas and rotors, now might, however, again - with as low as possible expenditure- get into the amateur radio over satellite. Thanks for answers , Jens / HB9JOI
