Here's a colour ( or color ) coded Radio Spectrum Allocation chart in PDF
format of a 2'x3' poster that just about every Canadian amateur has posted
in their shack.


The olive color is amateur and the olive with dots is amateur shared.    

|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.
