Friday, October 31 is the formal start of the 146-147 MHz ‘experiment’ for Full licence holders with NoV’s and the RSGB has released a bandplan.
The bandplan has an allocation for digital modes with up to 500 kHz bandwidth and 12.5 kHz channels for narrowband digital modes including digital voice.
Users of wideband modes may need to use bandwidth tailoring to ensure no RF extends into the weak signal satellite segment at 145.8-146.0 MHz (the Lunar 4M JT65B beacon uses 145.980 MHz) or goes above 147.0 (or 146.93750 where applicable).

Some amateurs will be active in the early hours of Friday with the digital voice mode FreeDV which uses Codec2, download FreeDV from http://freedv.org/tiki-index.php
