AMSAT-DL has agreed to a proposal by the British Amateur Television Club (BATC) for the use of the bottom 100 kHz of the wideband transponder (10491 – 10491.1 MHz) for ATV co-ordination purposes.

The announcement on the BATC Forum says:

This is on an experimental only basis and stations must keep their power levels to a minimum and certainly not exceed power levels greater than 15dB above the noise floor as shown on the Goonhilly spectrum monitor.

This is sanctioned on an experimental only basis and AMSAT-DL reserve the right to move the WB beacon towards the band edge or implement DVB-S with a wider rolloff which would render the frequencies unsuitable for this purpose.

So another challenge but should be manageable and prove a useful facility although we do see the chat being the major tool for reports and contacts.
