International news broadcasters are rarely available from just one place in the sky. The same service is often carried across several orbital positions, sometimes in different resolutions, sometimes free-to-air in one region and encrypted in another.
That makes "what is the frequency" the wrong first question. The useful question is which carriage suits the dish I already have — and the answer to that stays valid even when the numbers change.
Why one channel exists in several places
A broadcaster leases transponder capacity, and capacity is bought per region. Serving audiences across different footprints means separate carriage arrangements, which is why the same channel can appear:
- On several orbital positions at once, each covering a different region
- In both standard and high definition, sometimes on different transponders
- Free-to-air in one footprint and encrypted in another, depending on the rights deal
- On more than one transponder at the same position, at different bitrates
So a listing that works perfectly for a viewer in one country may be irrelevant to you — not because it is wrong, but because it describes a beam you are not inside.
Work from your dish, not from a list
The practical sequence is the reverse of what most people try.
- Establish which positions your dish can already see. A fixed dish sees one; a multi-feed setup sees two or three; a motorised dish can reach much of the arc.
- Find which of those positions carries the channel in a form you can decode — free-to-air unless you hold a subscription.
- Only then look up transmission parameters, or better, scan for them.
Working this way avoids the most common dead end: chasing a published frequency for a satellite your dish is not aimed at, and concluding that something is broken.
Why scanning beats a published list
Every frequency list describes the past. Broadcasters move between transponders, change symbol rates, switch modulation or drop a service, and no list updates itself.
A blind scan sidesteps this. Rather than checking a stored table of transponders, the receiver sweeps the whole intermediate frequency range looking for carriers, measures each one's parameters itself, and reads the service names directly out of the stream.
That last point is the important one. The name carried in the broadcast is what the broadcaster themselves published — making it a more authoritative source than any third-party listing.
The cost is time: a full satellite can take tens of minutes, because the receiver is genuinely searching rather than checking known addresses.
One caveat. If you are receiving nothing at all, a blind scan is the wrong next step — it will run for half an hour and find nothing, because the problem is upstream: alignment, cabling, LNB power, or the wrong satellite. Confirm you can lock at least one known transponder first.
Free-to-air or encrypted
A channel appearing in your scan results does not mean you can watch it. A transponder can lock perfectly while its services remain encrypted.
Most receivers let you include or exclude encrypted services when scanning. Including them is useful diagnostically — it confirms the transponder is live and your alignment is good — even where the content will not display.
Rights arrangements are also why the same broadcaster can be open on one satellite and scrambled on another. That is a licensing decision, not a fault in your equipment.
Which parameters actually matter
When you do enter details manually, four values are required and each does a distinct job:
| Parameter | What it selects |
|---|---|
| Frequency | Which transponder on the satellite |
| Polarisation | Which of the two overlapping signals to read |
| Symbol rate | How fast to expect symbols, so how wide the carrier is |
| FEC code rate | How much of the stream is error correction rather than payload |
Get the symbol rate wrong and the receiver will not lock even with the frequency and polarisation correct — it is looking for symbol transitions at a rate that does not match what is arriving.
Newer carriage may also need DVB-S2 with a particular modulation such as 8PSK. A receiver locked to DVB-S and QPSK cannot decode it, and no configuration change bridges that gap — the error correction and modulation are genuinely different.
When a channel that worked stops working
| Observation | Likely explanation |
|---|---|
| Gone, but other channels on the dish are fine | Moved transponder — rescan that satellite |
| Locks but no picture | Now encrypted, or wrong modulation set manually |
| Older receiver lost it, newer one still has it | Moved to DVB-S2, which the older tuner cannot decode |
| Breaks up only in rain | Higher-order modulation or code rate, leaving little margin |
| Nothing at all on any channel | Alignment, cabling or LNB power — not the channel |
The pattern worth internalising: if one channel disappears and its neighbours are fine, the change is at the broadcaster's end. If everything disappears together, the change is at yours.
Everything works fine except one channel, just black screenโฆ any idea why?
