Ok granted 2.40 GHz to 2.45 GHz has a high noise floor and will get worse. So this will be a good band for uplinking.
I know it's not a satellite allocation but what about a downlink around 2310 ~ 2390? Or maybe 2300 ~ 2302? I also know that some countries have lost access to 2.302 GHz to 2.4 GHz (VK is one) but as a downlink no one is stopping us from listening there.
Or must a satellite transmitters be compliant with all international allocations? Or maybe 2300 ~ 2302 would upset to many other users?
Unfortunately, there is no country that allows the use of 2.3 GHz for amateur satellites and only one country in the footprint of the satellite would have to object.

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.

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 FCC specifies amateur satellite frequencies in 97.207 and 97.209.

Didn't we get an exemption once for AO-7 for an out of band uplink?

I thought AO-7 was launched *before* the satellite sub-bands were decreed? Jim

Neither the United Kingdom or Germany have an Amateur allocation at 2300-2310 MHz.
The UK's allocation is 2310 - 2450 and Germany's 2320-2450, hence the adoption of 2320 for weak signal (CW/SSB) terrestrial working in Europe.
So at present I think only 2390-2400 is common between US/Europe.

Australia has only 2400-2450 available in the major population centres. I believe 2302 - 2400 is still listed as amateur, but there is an exclusion clause around the major cities, as this band is used commercially, and no amateur operation is allowed.

Hi, Alls,
Please do not forget that there are many amateurs who are in big interest in Japan too.
And satellite allocation on this band is 2,400 to 2,405, within whole of the allocated band for amateur, 2,400 to 2,450MHz. There is no amateur allocation on 2300MHz band for us.
73s Toyo JA0CQP
Just a reminder that here in Region 1 all our terrestrial and satellite service allocations between 146MHz and 24GHz are only secondary or, even worse, by footnote.

Graham G3VZV
Good point Matt,
I believe that 2390-2400 is the only part of 2.3 - 2.4 GHz that is common to both the USA and Europe.
Much of Europe has lost 2300-2310 and now use 2320-2330 for terrestrial use.
I understand that Japan only has 2400-2450 MHz.
While I believe we should try and get a world-wide Amateur Satellite allocation at 3400-3410 MHz there's a lot to be said for trying to get an additional 10 MHz Satellite allocation somewhere between 2.3 and 2.4 GHz.
