Remember that the purpose of the digital modes on Eagle is different from PACSATs. The object of the ACP is to make a HEO EasySat that provides worldwide communications with smaller antennas. Class 1 provides a PSK31-like service with small, fixed antennas on the ground. Since it's U/V and most amateurs have PCs, most will probably be able to use it. However the real reason is to make AMSAT satellites available to more people at a lower ground station cost and also make them easier to use from remote locations. Class 2 provides digital voice and data with smaller rotatable antennas than needed today so it allows hams with limited space to use the satellite. It also makes portable stations smaller. Class 3 just allows larger ground stations to do more things -- with bigger antennas and more uplink power they can push more bits through the same hardware as class 2 users.

As far as I can tell, AMSAT has put the linear transponders that the majority of its members wanted on each phase 3 satellite. Adding digital services that the rest of the world is using seems likely to attract more members than continuing with the same old strategy.

My dear Mr Stephenson ESQ
There is also a lot of cube sats in the making who will also carry on digital capabilities but for the sake of the AMSAT'S Can we let them carry on a simple satellite where you and me can discuss of you ideas. As you and me are also aware it is not all the satellite community who can use digital modes.
On the rest i agree with you but it seems there is not enough space available in Eagle and i'm afraid many will missed the train. I think P3E will have some sort of digital system.
