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 

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,

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
