> The front page of the newsletter, edited by *Michael Kastelic OE1MCU*,
> says The Cavtat conference has already recognised the frequency requirement
> for digital voice, and the bandplans have been adjusted accordingly.
>
> We see, however, further development in this direction, with rising number

> repeaters operating even in the 2m satellite segment.
> See http://www.dstarusers.org/repeaters.php
>
> *The situation is deplorable. We complain about interference in the
> satellite segment caused by pirates and telephony systems, while blocking
> the satellite segment ourselves, not to mention interference due to
> irregular repeater shifts*.
>
> *Whenever a new D-Star repeater is to be set up, it must operate on a
> coordinated frequency pair, even if this means that an existing analogue
> repeater has to be switched off for this purpose. I urgently request all VHF
> managers to monitor the developments in their countries and to use their
> influence to redress the situation as required.*
