As I said previous to this note, our analysis and all of this hoopla is released too early. We have not fully prepared for the onslaught and we have only done a <<technical analysis>> that resulted from the assumption that Galileo was going to cause loss of L band. It is not in our political interests frankly for this understanding to be widespread but now that it is, we might as well go ahead and do all of our "worst case scenario" analysis in public.
It is my understanding that Argentina and the Netherlands have LOST 2400-2450 for use by terrestrial radio amateurs because of interference from amateur radio operators (primarily BLOODY ATV) to 802.11 services. Amateurs have been told to stop transmitting in those bands. I need much more information.
DO NOT SEND YOUR ANECDOTE HERE.
Please send to me DIRECTLY your personal, first hand knowledge of loss of 2400-2450 IN YOUR COUNTRY or any other country FOR WHICH YOU CAN PROVIDE DOCUMENTARY EVIDENCE. I have no interest whatsoever in rumor. I need facts. If this phenomenon is widespread, then the use of S band as an uplink is a useless argument to be having and the whining can stop. ALL that was done in San Diego was a technical analysis. No legal or political analysis has been done at all. We are not prepared to say "This is what we are doing". We are prepared to say "This is what the technical folks came up with given the assumption of the loss of L band and the assumption that 9 cm would be politically unacceptable". NOTHING ELSE should be assumed now.
But let me repeat (ad infinitum?), I am personally interested in managing the design and building of an instrument that accomplishes the AMSAT vision statement. If I find that we have essentially lost all microwave bands we have in the amateur satellite service that can be used effectively to support the vision statement (given engineering computation and "circuit practicalities"), I will lose interest in managing this whether it be an AMSAT political decision or an international frequency disaster which we have allowed to go unanswered in any substantive way. AMSAT-DL is the perfect vehicle to produce P3 spacecraft with our help where needed. We do not need to duplicate their efforts.
DO NOT send your anecdote to this list. Send your FACTS to me, with supporting evidence, so I can summarize what I believe the impact of this to be for the AMSAT BOD.
