To enable easy decoding PIDs should be set as: Video 256, Audio, 257, PMT 32 or 4095, PCR 256 or 258. Service
Name should be set to CallSign. PMT PIDs 4000 - 4010 should not be used. Users are encouraged to experiment
with higher-order DVB-S2 modes at lower symbol rates (for example 333 KS 32APSK) to conserve bandwidth for
other users.

On Wednesdays (UTC time), experimenters are encouraged to try other modes - perhaps 6 MS using the whole
transponder for brief (less than 10 minute) periods. It is essential that users to announce their plans on the chat
room page, and to always monitor it.
