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?
