over the XMAS "maintenance" period we are planing some changes on the DATV beacon to allow for more user space.
1) new DVB-S2 parameters
DVB-S2 QPSK; 3/4FEC; 1500kSymbole; RollOff=0,25; Pilots=off
Thus the occupied bandwidth will reduce from ~2.5 MHz to ~1.9MHz while the picture quality should only change slightly.. 0,9dB more C/N required.
2) Center frequency
We will be trying to move the DATV beacon as much to the edge of the transponder as possible and useful without too much degradation. This should give us another 0.5 MHz of more room on the transponder.
New center frequency will be published after the change..
Currently we are planning the 25th or 26th of December to perform the changes...
