Hi Art,
Thanks for the reply.

The general principle is that the amateur-satellite service has frequency allocations in bands where the amateur service has frequency allocations in all three ITU regions.
I'm not so sure that's so.
The amount of new Amateur Satellite Service spectrum allocated by ITU since the mid 1970's is ZERO but the Amateur Service world-wide has gained spectrum.
The only exceptions are in the bands 1260-1270 MHz and 5650-5670 MHz, which are limited to the Earth-to-space direction, and 3400-3410 MHz, which are available in Regions 2 and 3. See RR 5.282.
As you say back in the 70's 1260 and 5650 MHz were made Earth to Space only. Does anyone know why this restriction was put in place ? Or even if the reason for this restriction still applies 35 years later ?
So, until broadcasters vacate 7100-7200 in Regions 1 and 3, the amateur-satellite service won't have a frequency allocation. Make sense??
No, an Amateur Satellite Service allocation at 7.1-7.2MHz is not on the agenda for the next WRC in 2012 and currently IARU has no plans to ever ask for one! See IARU spectrum requirements at: http://www.iaru.org/ac-09spec.pdf
In it's entire history the IARU has not gained any ITU Primary Amateur Satellite allocations in the bands above 146 MHz. We have no Primary allocations above 146MHz until you get to 24GHz.
While it is encouraging to see that IARU would like to see Amateur Satellite Service allocations at 50MHz and 3400MHz there are no other proposed Amateur Satellite Service allocations on its agenda.
The ARRL is by far the largest financial donor to IARU and so carries the most clout.
If ARRL isn't persuaded of the need for additional Amateur Satellite Service allocations they won't happen.
