Re: NCS for ISS/FM leo sat's



Bob my point is if somebody hears a grid/state that they need or an operator 
is operating from a rare grid locator then why should they need a hallway 
pass to work it.

a NCS works great on a HEO satellite as you have time to take check ins and 
can pass it around and you have the band width, but you are talking about a 
8 to 10 minute window not worth it.
