Here is the colored PDF chart of Emily's previous link.  Zoom in on the PDF
in the 2300-2305 ( about 150% on my Acrobat reader )to see closely what
Emily is referring to.

|The detailed chart (
|http://www.ntia.doc.gov/osmhome/Chp04Chart.pdf  - starting on page
|50) is a bit fuzzy but it looks like amateur is allocated from 
|2300 - 2450, albeit all on a secondary basis.  Currently there 
|is a 5MHz amateur allocation at 2300-2305 in all three regions 
|and a 10MHz allocation at 2390 - 2400.  I believe the 
|2390-2400 is primary as it appears in all caps and 2300-2305 
|may also be primary.
|This doesn't mean these are available for satellite use.  The 
|only bandplan I have found for this spectrum comes from the 
|ARRL website.
|But it is a bandplan, and bandplans are subject to change.  
|For example, there is 800 KHz allocated between 2303.0 to 
|2303.8 and another 500 KHz between 2399.0 and 2399.5 for low 
|rate packet.  Can the use of that part of the bandplan be 
|negotiated?  I don't know.  However I will be very interested 
|in hearing Paul Renaldo's presentation in San Francisco and 
|meeting with the other members of the IARU.
