what frequency does DSTV transmit/receive at?

[techead]

anyone know?

I think its around the 11/12Ghz range but I cant find anything online to back this up.

Im figuring its got to be something quite low(ish) otherwise we would never get a signal while its raining!!

thanks

AFIK just reboot the DSTV and i think you can see the frequencies it is scanning
I seem to remember 11/12 gig

thanks good idea, but Im not at home at the moment..

DSTV broadcasts on the Ku band

Europe and Africa
Segments in those regions are represented by ITU Region 1 and they are, the 11.45 to 11.7 and 12.5 to 12.75 GHz bands are allocated to the FSS (fixed satellite service, uplink 14.0 to 14.5 GHz).

11310 to 12750 GHz. Your LNB reduces the frequency to around 10% of that value and amplifies it. Dual and Quad LNBs are always connected, single LNBs switch the horizontal and vertical aerials according to the incoming voltage

Vert is around 11/12Ghz
Horz is around 14/15Ghz

There is no FIXED single freq in use. It connects to numerous transponders, each operating at their own frequency between 11/12 and 14/15Ghz

No. I think you are confusing the voltage that is used to select vert/hor at the LNB with frequencies. Ver would be around 13V and Hor 17/18V.

Anyway, here is a link to a list of transponders DStv uses and their frequencies:

Is someone you know getting ready to hack it?

Unfortunately those lists are very outdated.

Currently they are using 13 low band tranponder, vertical and horizontal, from 10970MHz - 11594MHz. These frequencies are dropped by 9750MHz by the LNB, to frequencies between 1220MHz - 1844MHz. New transponders and capacity will be available later this year, when they switch to IS20.

Any idea how many transponders they will be using on IS20?

More than 50% more capacity... Obviously the will not utilize it all immediately.

The frequency sent down the coax is actually an IF signal... the incoming high frequency is mixed with an equally high but offset LO to get a difference frequency by heterodyning
