Luc, John and the Group,

I want to wish everyone a Healthy and Peaceful New Year, and I hope that Santa was good to you; I know Santa gave me a terrific Satellite gift.

I asked Alan to give me a better understanding of how signals are processed with XO-68, I hope his explanation below helps.

Dear Peter,

FM / Digital working principle is that whoever will relay signal to who should transmit first. the transponder is not torn between the uplink signals.

In other words, if the voice first, open the repeater and talk, this time where the transmitting packet data is necessary to wait for voice communication before end of the processing voice. By the same token, if you are transmitting Packet data into voice link from time to time, the satellite will continue to transmit the packet data to complete the data frame, and then process voice request if the request is still active.

On the other hand, if there are a lot of very strong signals transmit to the satellite at same time, the satellite receiver may be unable to decode 67Hz PL correctly, so voice will be unable to be replied in that case.

Happy Holiday!

73 Alan, BA1DU
