Jim,
The ITU has already listed 3400 to 3410 MHz as the authorized secondary amateur satellite band for regions 2 and 3. Their HSMM proposed band plan is just consistent with what is already allocated.

Team: This is the response I got to an email I sent after seeing the latest CQ-VHF. The successors to the HSMM effort are proposing a digital band plan, and have included us. They gave us 3400 to 3410, as an initial proposal.
SO, digital guys, is this enough? In the discussions I've been part of, we spoke of 10 MHz as a minimum, and we spoke of it as nominal. How much do we REALLY need? What's been published is a proposal, the beginning of a conversation. I know we're a long way from saying, "this is what it will be," but can we articulate a needed bandwidth based on what we know now? I'd like to think that we can, but will defer to you who are smarter than me on these things. You who are more familiar with the international regulatory scene, is this a good freq range, or should we ask them to move?
These guys like what we're doing and want to support us. Good things are happening!
Thanks & 73, Jim [email protected]

Jim...
I passed it on to Drew Glasbrenner-KO4MA. Drew coordinates the Florida AMSAT Net on the NI4CE Repeater System (and other repeaters that link into NI4CE via Echolink). Drew indicated to me he would pass the bandplan up the line. I haven't seen what CQ published as yet.
The bandplan reserves a window between 3.400 GHz-3.410 GHz for EAGLE and other satellite operations. /*If that is not suffficient, please let me know. The proposed bandplan is really more a suggestion for broadband network operations rather than something set in concrete.*/ ARBA, Inc. (Amateur Radio Broadband Alliance) came up with this to provide some guidance to those who want to build broadband wireless networks. We recognize that existing local activity on the band will need to be accommodated.
I applaud the work you and AMSAT are doing. One of the missing links in Amateur Radio disaster communications has been digital satellite capability over an extended period (more than give or ten minutes at a time). EAGLE will help fill that need.
Very 73 de Paul-NA4AR

Paul: I just read your article in CQ-VHF regarding HSMM work. In one of the figures, you mention passing on a proposed band plan to AMSAT for coordination with Eagle.
Question: to whom did you pass that on? I'm the Eagle project manager and have not seen it, other than the chart in the article.
GOod article, congratulations.
Thanks & 73, Jim [email protected]
