Hi!
We can experience the delays you mentioned, even with LEO satellites today. Use an SDR receiver on the downlink. Unless the computer is very fast, there is a lag in hearing the downlink. It was annoying at first, but now I don't worry about listening for my voice. I can see signals on the waterfall in the SDR software, and as long as I can hear my voice coming through... I'm fine.

GEOSATs have another interesting characteristic. 600 ms round trip delay due to the longer distance.
600 mSec is almost a triple hop, so not that long...
For those of us that operated on AO-40 during it's unfortunately short life, when it was at or near apogee, it was well beyond the Geo belt, and that was entertaining. Of course most people on linear birds operate full duplex and it took a little to get used to hearing yourself with such along delay...
