@kenbarbi @Konrad_Roeder As active and vocal community members, I’d like your feedback on EchoStar-9 vs Galaxy 28. By no means is this discussion limited to Konrad and Ken. Everyone is welcome to chime in.
The reality is that one beam is not going to be ideal for everyone in the country. Right off the bat, we are looking at 121W vs 89W. On the East Coast, we’re looking at an elevation of 21-degrees for ES9, whereas G28 is 21-degrees for the the Northwest.

ES9 has a 27 MHz transponder. That means that the power available, EIRP of 48.3 dBW, is spread across less bandwidth, which means we get more bang for the buck. You can also see that ES9 provides full coverage of Mexico, which could be useful for earthquake warning systems. Guatemala is also fully covered with a power level that is similar to the US.
G28 has 36-MHz transponders with most of the coverage area under 49 dBW EIRP. This difference in power and transponder bandwidth comes out to about 15kbps worth of SNR. That’s the difference between being able to provide streaming audio…or not.
No decision has been made yet, but I’d like to make one very soon. I can’t make everyone happy, but I will listen to all of the feedback. Looking forward to your thoughts.
