Re: L band uplink frequencies
by Fabio A. IZ5XRC 18 May '12

18 May '12

Hi, I think the suggestion is still valid, the "alternative" proposal, being at the band edge, may be useful to minimize any possible interference. The attached pictures might help The E6 band is located between 1260-1300MHz, centered at 1278.75MHz, it is not an Aeronautical Radio Navigation Service (ARNS) band, GPS is not broadcasting its signal in that band also. Anyway, E6 band is dedicated to commercial services (CS) and that must be taken into account. To read further, one interesting reference is: The Radio Science Bulletin (URSI) N.330 - SEP 2009 Hope that helps 73s Fabio IZ5XRC (ex iw8qku) > Hi all. > > I am trying to determine an FM uplink frequency in L band which is > suitable for most countries. > > As I understand it, 1269 is the traditional frequency of choice, but with > Galileo now being deployed and some local EIRP restrictions here in Europe, > that may no longer be the best choice. > > In searching the AMSAT archive I saw several messages about the P3E > 'galileo alternative' at 1260 and a message saying that there is an EIRP > limit in Germany below 1263MHz. - Is that still accurate?

HORYU-2 Telemetry Competition
by Trevor . 17 May '12

17 May '12

The launch of amateur radio satellite HORYU-2 takes place Thursday, May 17 at 1639 UT. The satellite callsign is JG6YBW and radio amateurs are asked to listen for the 437.325 MHz telemetry downlink which is in Morse Code or 1200 bps AX.25 packet radio. There is a monthly competition for those who send data received from the telemetry to the KIT server, via the HORYU-2 telemetry analysis software. The free HORYU-2 telemetry software and details of the competition can be downloaded from http://kitsat.ele.kyutech.ac.jp/Documents/information_launch_english.html Information on HORYU-2 is also at http://www.uk.amsat.org/7404 73 Trevor M5AKA AMSAT-UK News on Twitter: http://twitter.com/AMSAT_UK AMSAT-UK: http://www,uk.amsat.org/ ----
