MVision HD300 Combo Box - Cannot tune in Terrestrial

spfeno

Dived into the deep end and just purchased the MVision HD300 Combo from SaorTV for teenagers/kids playroom

Have been toying around with the box and have managed to scan in the satellite channels (satellite is fixed with a quad LNB and another line running to main room with Sky subscription) and have saved & organised the channels I require BUT it isn't picking up any of the Terrestrial channels when I scan.

I'm living in Ratoath and have a large, roof mounted Yagi aerial pointing toward Three Rock (at least I'm assuming its Three Rock). All the terrestrial channels were being received perfectly prior to MVision box purchase (so why change it I hear you ask; )

SaorTV mentioned it could be receiving analogue signal from an in-fill transmitter (and not Three Rock - again as I've said I assume its Three Rock since its pointin that way).

1. How do you know if your UHF aerial is pointing toward a main transmitter and not a relay

2. Since I'm living in Ratoath, does anyone know where I should have the UHF aerial pointing to in order to get DTT signal. Rather leave it alone if I don't have to move it as it's a large roofmounted piece of kit (professionally installed a number of years ago)

Hoping someone can help as its really bugging me

I had a problems where I could find nothing on a scan for ages from Maghera because RTE did something with flags or offsets meaning that the box could not lock onto the correct base frequency or expected flags for a mux and all the channels are on one mux .

I had had them and others had them all the time but scan would not find. Eventually it was 'fixed' last week and I couls scan and FIND and store again. Phew.

One kludge during terrestrial tuning is to change country to one of these 4, UK or France or Norway or Sweden and rescan . Make sure you understand the menu system in case a language confuses you .

If you then find channels store them and change back to Ireland afterwards.

The standard settings in the terrestrial search shold find Irish DTT if in coverage. Are there any infill transmitters covering the Ratoath area?

If you have access to your arial turning towards Cairn Hill should resolve your issue.

assuming you have a digital tv.......

if you bypass the box and connect the aerial straight through to the tv and use the DTV input to the screen, and tune the tv, you should get the radio stations and and the terrestrial sound.

Then insert the box to decode the TV picture.

Hope this helps.

All this will elimate is if the Mvision DVb-T is working. You cant use this setup to receive DTT on the Mvision. The aerial needs to be plugged into the Mvision.

Aye, I know.

That's why you put ther box back in!

Can you explain what you're getting at? What's the point in tuning the TV to the DTT channel? Is it to eliminate a problem with the aerial? It's the Mvision box which needs to be connected to the aerial and the channels scanned. The box passes the video and audio to the TV via the SCART or HDMI connection.

Ok - update
Spent the day turning the aerial around and its now pointing North to Clermount Carn (I assume this is what its picking reception up from - could also be a relay transmitter I read about somewhere in Monaghan). Analogue reception is once again perfect for RTE1,2, TV3 & TG4. When I try scan thru the MVision still no joy. I performed AUTOMATIC scan with the Power Option on the Menu both ON and OFF and NADA (This was suggested earlier in the thread).

If my analogue is being picked up fron a relay are the DTT signals broadcast from these too ?

Note:
There is a second smaller aerial which I believe is to pick up TV3. This is attached to the main mast. Also attached is what I believe to be a mast head amplifier.

After spending most of the day in what felt like sub-zero temperatures on the roof I feel like driving a lump hammer through the whole lot

Help Please !!!!!!!!!!!!

What Frequencies/Channel Nos are you picking up the Analogue services on now.

What Frequencies/Channel Nos were you picking up the Analogue services on before.

Sounds to me like you are using a Group A yagi for Analogue from Three Rock but RTE DTT is on Channel 54 on DTT.

Sponge Bob

The main aerial may be VHF and the smaller one may be the right aerial as DTT and TV3 and TG4 are picked up off UHF not VHF . Dunno why TG4 would come in off the main aerial, should only do 1 and 2

The general rule is that if you have TV3 you can get DTT

If you have a friend with perfect TV3 and TG4 nearby try to plug it into their house and see if tuning works.

If so the TV3 aerial may have a filter that blocks the DTT frequencies or may be the wrong group ( unlikely) or may only amplify parts of the UHF band that are not used for DTT at the masthead .

sorry f-t,

obviously not making myself clear..

"Is it to eliminate a problem with the aerial?"

Yes.

I'm guessing that what your main (big) aerial was pointing at originally was Kippure - not Three Rock. This is a VHF aerial and would get RTE1 on VHF channel E, RTE2 on VHF channel H. The smaller aerial would be UHF and, if also pointed at Kippure, would get TV3 on UHF channel 62 and TG4 on channel 59. It's this aerial which would provide the DTT signal from Kippure on UHF channel 54 or 61. I'm not able to verify if Kippure is transmitting DTT at present as I'm shadowed from that transmitter. Kippure would be just slightly East of due South from you. Three Rock would be would be more South East at a bearing of 153 degrees according to Google Earth. So if your smaller UHF aerial is pointing slightly further East, then it's pointing at Three Rock and should pick up the DTT signal from there - also on UHF channel 54 or 61. Three Rock transmits its analogue signals on UHF channels 29, 33, 35 and 55.
Depending on how your aerial downleads are being combined it's possible that there is some filtering going on which is affecting the DTT reception, but it's not likely if you are getting good TV3 reception from Kippure on ch 62 or Three Rock on ch 35.
There is also the possibility that the DTT tuner in the Mvision is fecked:(
I have used the Mvision HD200 for about a year now and I find it fine except for the power consumption in standby and the fact that it runs quite hot.

spfeno

Thanks for all the replies guys - I don't know what they were BEFORE I moved the aerial but now its pointing North (ish) toward Clermont here is the deal -

RTE1 - Ch 52
RTE2 - Ch 56
TV3 - Ch 66
TG4 - Ch 68

CH4 - Ch 21
ITV - Ch 24
BBC2 - Ch 27
BBC1 - Ch31

All the above are on SYSTEM I according to the TV

Any further suggestions ?

SLEGS what do you reckon - any possibility the DTT tuner is gone as per above advice ?

regards

Spfeno

P.S. - Fat Tony not sure what the standby power consumption is like with the 300 yet but it doesn't run hot at all

Those analogue channels are for Clermont Carn all right. The System I reference is to the PAL subtype used in Ireland/UK.

If you plug the aerial lead into the Mvision and manually tune to Channel 53 on the Terrestrial menu (I'm assuming the 300 has a similar menu structure to the 200) you should get a signal reading from the Clermont Carn DTT multiplex (assuming it's active!). The other multiplexes allocated to CC are 57, 60 and 63 but it's unlikely that any of these will be active regularly.

You should have the antenna power option turned off in the Mvision menu as I assume your masthead amplifier is powered separately.

Here's a page from the RTENL DTT document which shows the current analogue and allocated channels for DTT for the various transmitters. May be of use, perhaps?

Benolam

I was about to buy one of these (Mvision HD300 Combo) so I am interested in finding out what is wrong. A few questions: Did you go for the €20 pre-tuning option? This is where SaorTV tune in the BBCs ITVs CH4s etc. from Astra/Eurobird and also your local Irish DTT TX as advised by the buyer.

When you tune to an occupied UHF channel do you get any indication of signal strength or quality? Even an analogue channel will register signal strength, albiet in red rather than green, with zero quality indicated).

Apart from the obvious problem what are your comments about the box in terms of build quality, performance, ease of use, instructions, video/audio, features etc.

Benolam

Another point, r/f bandwidth must be 8Mhz. (some boxes have an option of 7Mhz).

F-Tony,

Did the above and still no joy

I response to previous reply my TV3 reception is excellent (probably overall the best reception of the four Irish channels) - following from this I'm leaning toward the DTT tuner being faulty. SAORTv have kindly agreed to replace same

Many thanks for the advice
guys - keep up the good work

1. No I didn't go for pretuned option - the setup is very user friendly and easy to use

2. Nothing on either SIGNAL or QUALITY bar

3. Build, ease of use, instructions and all features are excellent - the satellite reception from this is fantastic - its my first time really witnessing HD which is broadcast FTA by BBC - absolutely classic

SaorTv have kindly agreed to replace the unit FOC - so hopefully I'll sort the terrestrial glitch - will keep you informed

The HD200 doesn't give any indication of signal strength/quality on an analogue channel - the method of modulating digital signals on RF is completely different to analogue. I'd have thought the HD300 was the same - does it work differently?

Ok - sorry to hear you might have a faulty unit. Fair play to Saor for replacement option.

I dont have an Mvision. I have a Clarke-Tech Combo and a Vantage Combo. Both show signal strength on analogue channels. (e.g. 29 & 33 from Three Rock). I thought that the Mvision would be the same.

'fraid not - certainly in the case of the Mvision 200 combo!

FINALLY, FINALLY, FINALLY PROBLEM SOLVED -

Tried the 300 Combo box on a bedroom connection (established since last post) and the terrestrial channels tuned in - so the tuner was not the problem !

Started afresh in the room with the problem - went thru every connection with fine tooth comb AND discovered that the solder had cracked inside the wall coax/satellite connection plate that the box was plugged into. Got out soldering iron, fixed the problem and terrestrial channels tuned in no problem - talk about a dog with a bone !!!

Strange how the terrestrial reception was perfect when it was tuned directly to the TV but when through the 300 combo it wouldn't pick the channels up - but there you go !!!

Got this box yesterday, does anyone know how to tell if the terrestrial channels are coming throught DTT or analogue?

I have a sony tv which has an integrated digtial tuner, and is hd, but is there any inofrmation on the epg on this box to show if they are dtt i am picking up? I heard that rte two is hd on dtt now?

If you have an Mvision and you are seeing TV through the aerial connection, then it's digital. When you press the EPG button (on either the Mvision or the Sony and you get an EPG, then you are pretty likely to be receiving the digital signal. RTE Two is in upscaled SD to HD resolution on DTT.

Have you 4 channels or 17?

Analogue has no 3e or RTE News now.

No analogue tuner in the Mvision

shortys94

OOO thank you I see that now, was also wondering is there any way to use a sony remote with the mvision box instead of the one which came with it?

And some programme listings dont load up, is there any way to fix that?
