What it is for
“By channel or multiplex” searches for terrestrial TV channels (from a rooftop or indoor aerial) on a single TV channel that you pick from a list: VHF channels 5-12 and UHF channels 21-69. A multiplex is a bundle of programmes broadcast on one such channel.
You do not type in any frequency: each channel shows its frequency next to it. In Romania, the channels used by the MUX1 network also show the counties, for example “Channel 21, 474 MHz (MUX1 in Alba, Arad, Hunedoara and 4 more)”, and the preview shows all of them.
Only the chosen channel is searched, with no other frequencies from the signal. To search the whole network, use “Automatic” or “By region or provider”.
Important: for now the image tunes DVB-T only. Terrestrial TV in Romania (MUX1) is DVB-T2, so the search here finds 0 channels until a future update of the image. The receiver warns you before it starts and asks whether you want to search anyway.
The chosen channel is the same as the “Start channel” in “Automatic”. The same kind of search is also available in the web interface, on the /scanare/terestru/canal page.
How to get here
Path: Main menu > Channel scan > Terrestrial > By channel or multiplex
Remote keys: MENU 1 3 1
In the web interface: the /scanare/terestru/canal page (the “Channel scan” tab, the “Terrestrial” group, the “By channel or multiplex” button).
What you see on the screen
At the top: the title “Terrestrial scan: By channel”, the time and the date. In the Pro theme, the blue square with the logo is to the left of the title.
The list has two rows: “Channel”, with the chosen channel on the right (long text scrolls by itself), and “Search now”. The selected row has a blue background.
Below the list is the preview: “Channel 21, 474 MHz. MUX1 broadcasts on this channel in: Alba, Arad, Hunedoara, Maramureș, Sălaj, Satu Mare, Timiș.”. For a country other than Romania, this is added: “The image can only tune DVB-T for now: DVB-T2 multiplexes will give no channels until a future update.”.
Underneath, in yellow, is the status line, showing what the keys do or the last message (“Saved.”, “The search did not start.”).
At the bottom, the colour keys: RED “Back”, GREEN “Search now”, YELLOW “Change”, BLUE “Save”.
OK on “Channel” opens the channel list, full screen: the heading “VHF III, 7 MHz channels:”, channels 5-12, then the heading “UHF, 8 MHz channels:” and channels 21-69, each with its frequency (and, in Romania, the MUX1 counties).
Once the search starts, the “Channel search” screen opens: at the top “Terrestrial” and the channel being tried, the moving dots, the percentage, the progress bar, “Time left” and “Transponders: x of y”. At the end you see the summary with “Channels found”, “Transponders scanned”, how many had “no signal”, and “Duration”.
Rows and settings
| Row | Values | Default | What it does |
|---|---|---|---|
| Channel | Channel 5, 177.5 MHz … Channel 12, 226.5 MHz (VHF III, 7 MHz), Channel 21, 474 MHz … Channel 69, 858 MHz (UHF, 8 MHz) | Channel 21, 474 MHz | The TV channel to search. The receiver sets the frequency and bandwidth (7 MHz in VHF, 8 MHz in UHF) from the channel. In Romania, the note “(MUX1 in …)” shows the counties where the MUX1 network broadcasts on that channel: MUX1 uses a different channel in each area. When you know which channel the multiplex in your area uses (from the transmitter list or from a TV that is already tuned). |
| Search now | OK on this row starts the search, the same as the GREEN key. The chosen channel is saved before the search starts. After you have chosen the channel. | ||
| DVB-T and DVB-T2 (what it can receive now) | DVB-T: yes, DVB-T2: not yet | This is not a row on the screen. The receiver's tuner handles DVB-T and DVB-T2, but for now the image only sends it DVB-T tuning data. DVB-T multiplexes (for example in some neighbouring countries) are found; DVB-T2 ones give 0 channels until an update of the image, which will pick them up with no other change on this screen. | |
| Channels found | They are written to the channel list only at the end of the search. Existing channels are not deleted; channels found again are updated. You find them in the channel list under Satellites › Terrestrial. |
Keys
| UP / DOWN | Moves the cursor between “Channel” and “Search now”. From the last row, DOWN goes to the first, and the other way round. |
| LEFT / RIGHT | On “Channel”, they go to the previous or next channel (from 12 it jumps to 21), without opening the list. |
| OK | On “Channel”, opens the channel list. On “Search now”, starts the search. |
| GREEN | Starts the search from any row (the screen shows “Search now”). |
| YELLOW | On “Channel”, opens the list, like OK (the screen shows “Change”). On “Search now”, it does nothing. |
| BLUE | Saves the chosen channel and shows “Saved.” in the status line (the screen shows “Save”). |
| RED or EXIT | Closes the screen and takes you back to the Terrestrial menu. The chosen channel is saved in this case too. |
| In the channel list: UP / DOWN, LEFT / RIGHT | Move the cursor one channel or one page at a time; the “VHF III” and “UHF” headings are skipped. |
| In the channel list: OK or GREEN | Chooses the highlighted channel and closes the list. |
| In the channel list: RED or EXIT | Closes the list without any change. |
| Yes / No (at the question before the search) | Choose with the arrow keys and press OK: Yes starts the search, No cancels. |
| EXIT (on the “Channel search” screen) | During the search, it stops it; the channels found so far are not written to the list. After the end, it closes the result. |
| OK (on the “Channel search” screen) | After the end, closes the result. While the search is running, it does nothing. |
Step by step
Search for a DVB-T multiplex on its channel
- Connect the terrestrial aerial to the receiver's terrestrial input.
- Press MENU 1 3 1.
- On “Channel”, press OK, choose the multiplex's channel and press OK.
- Press GREEN. If the question about DVB-T2 appears, choose Yes only if you know your multiplex is DVB-T.
- At the end, read the summary and press EXIT.
Find out which channel MUX1 uses in your county
- Press MENU 1 3 1 and go through the channels with LEFT and RIGHT.
- For each channel, the preview shows all the counties where MUX1 broadcasts on it.
- Note down your county's channel; you can search it once the image supports DVB-T2.
Start the search from your phone
- Open the receiver's web interface and go to /scanare/terestru/canal.
- Choose the channel from the list; below it you see the same preview as on the TV.
- Press “Search now”. At the question about DVB-T2, press “Search anyway” or “Cancel”. You can follow the search in the “The search on the TV” card.
Problems and solutions
The search on the MUX1 channel in my county finds 0 channels.
MUX1 is DVB-T2, and for now the image tunes DVB-T only. The channels will appear after an update of the image that adds DVB-T2; until then there is nothing to adjust on the aerial.
At the start, this appears: “The terestru tuner (…) is set to “not connected” in Tuner settings. Turn it on there, then come back here.”
Open Menu > Dish alignment and setup > Tuner settings (MENU 2 1), turn on the tuner for terrestrial, then come back here.
At the start, this appears: “The receiver has no terestru tuner.”
Your receiver has no terrestrial tuner, so it cannot search for terrestrial channels.
The summary says “No transponder had a signal.”
No DVB-T signal is coming in on the chosen channel: the aerial is not connected to the terrestrial input, it is pointed the wrong way, or there is no transmitter for that channel in your area. Try another channel or “Whole band” (MENU 1 3 2).
The preview says “Choose the channel from the list (OK).”
The saved channel is no longer in the list. Press OK on “Channel” and choose one.
I stopped the search with EXIT and I have no new channels.
Channels are written to the list only at the end of the search. Start it again and let it finish.

Differences between receivers
On the Amiko Viper 4K V20, the terrestrial tuner is tuner B, a combined cable and terrestrial tuner (DVB-C/T/T2); the search runs on it.
