[Bill Ress]

Hi Sanjay,

Thanks for the clarifications.

Best of luck with the upcoming launch and do let us know any additional 
details you might get concerning latest launch estimates, downlink 
telemetry format, Pout (10 mW was mentioned but not sure if this is 
accurate), and when the web site gets up and running.

Regards...Bill - N6GHz
