[QUOTE="tony smith, post: 1031750, member: 402577"] @ Channel Hopper, my comments were only ref this particular satellite Astra 19 1L, She's a Lockheed Martin 2100 with 14 Ka transponders, 30 Ku Transponders Her architecture for Ka up and K down is zoned ,with very limited cross strapping to change zones,she was intended for IP operation that's VSAT up and Earth station Hub down around 9 metre dia hub.Not DVB S2 SISLive have the UK lower 50mHz, and part of the upper 50mHz downlink, so are limited for space, so hence my comments ref guard bands( see DVB S2x ref levels/saturation/guardbands.) not just frequencies. [USER=407744]@s-band[/USER] if your headend is working then your rocking and rolling. Sis Live can run the lower 50 Mhz with 10 scpc channels they normally only run max 7 or 5 , then move up to the upper 50 Mhz, on top of this we have a data carrier at 18502 MHz which is uplink truck's to base comms, with another data link at 18562 MHz, which is base comms to truck, as well as ITN to ITV news regions 18556 mhz. So the unwanted rf carrier, is either local to you or lower level channel break through [/QUOTE]
