My S band equipment barely got any use with AO-40. Why put new higher 
freqs on Eagle and leave S Band off? Who wants to invest the time and 
money into getting gear for a new band when if that sat dies (like 
AO-40) did the next satellite might not even use that Band. Looks 
like I will stay with PSE for most of my time.
