Re: Some more details of XW-1



Hi Michael,

Thanks for update on XW-1.

A quick check of the IARU satellite frequency coordination web site 
doesn't shown XW-1 as being in the coordination process. Do you know if 
it's the plan is to have the frequencies coordinated with the IARU?

Regards...Bill - N6GHz
