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

Hi Bill,
As per the information I have, that 10mw is only on beacon mode and it
will change over to high power mode on command for payload down link.
