Col,

Do would you recommend these antenna installers without a Digital Field Strength meter?

After all they are "qualified" antenna installers

I really thought you would know the answer to that without asking.

I agree with you that an antenna system should be adjusted for Minimum errors but my point is that by giving a figure to the public and then saying that they should be aiming for lower figure is completely miss-leading and confusing because the public have no Idead what 8e-04 means .

To them its just a number "and If AlanH has said on the DBA forum "it needs to be less then lower numbers must be better right ?

So if 7e-03 is less because the numbers are lower than 8e-04 then it must be better BUT IT ISN'T is it ! I bet less than 1 in 10,000 of the public have any idea about scientific notation.

My other point is that because you don't specify CH BER or PV BER ,it would be possible for an unscrupulous type to show PV BER readings to an "enlightened DBA forum reader" and pass them off as wonderful BER readings .

So when DVB-T2 is used the BER may increase because it is capable of 16 signal levels at 16 different phase angles, however T2 has a more efficient error correction system. Compare this with the DVB -T standard of 4 x 4 signal level and phase or 8 x 8 level and phase.

Which is not relevant to the current discussion on DVB-T, as the acceptable ChBER and aBER will be completely different for DVB-T2, by definition, owing to the completely different characteristics of the new BCH/LDPC FEC used as opposed to the current RS/Convolutional system, and will also depend on the specific modulation and code rates used. Please stick to the topic and don't try to escape the question by dragging in irrelevant information. We are talking about DVB-T(1) here. Nothing else.

Note to any newbies reading the above post - please disregard, information directed at alanh only.

BelloTV.

I agree that I should have explained "Better than".

I am currently updating the transmitter list. I wll fix the "Get the Best Reception" posts then.

Incorrect

BelloTV,

Values of errors I have quoted are prior to any error correction ie Channel BER or aBER or Pre-Viterbi. The value quoted is from Australian Standard 1367

MER is the error ratio after all error correction and is not quoted as a ratio but in dB instead.

So BER will give the true level of errors. Post Viterbi BER is the errors left after the first attempt at error correction using the Viterbi Error Corrector. The signal is now Reed Solomon error corrected.

The MER shows how well the error correction system can remove the errors.

So the antenna installation should be adjusted to minimise the channel BER. Once this has been achieved the MER should be >25 dB

AlanH

MER and BER are both key measurements to be taken.

In the DVB-T system, their measurement take-off point is essentially the same.

Modulation Error Ratio (MER) is not measured "after all error correction".

And it doesn't ... shows how well the error correction system can remove the errors.

This shows a fundemental misunderstanding of how the DVB-T system operates. And what some of the key measurements are to try and make sure there is a reliable digital signal there.

This detail is taken further here.

A change in UHF band. Only replace antenna if the signals break up which may be weather dependent.

an

All analog channels within the antenna channel range will

ABC1 analog Narooma, Ashford, Inverell, Lithgow, Mudgee, Nyngan, Cobar, Broken Hill

Prime Central Tablelands, Mudgee, Khancoban, SW Slopes/E Riverina

WIN/NBN analog Bega, Murrurundi

Cabling SW Slopes/E Riverina

I'm not sure what the above means after the 'an'. Is there a missing line?

Also where can I find out when digital channels are going to be switched on in my area? (mudgee). Thanks.

Hi everybody,

I just purchased a Elgato Eyetv DVB-T USB stick for my laptop, as well as a Dick Smith L4069 Indoor TV Antenna. As I am currently studying at the University of New England in Armidale, I am not able to use an external antenna due to internal policies at my residential hall on campus.

At this time, I having issues getting my Antenna to pick up any coverage in any way shape or form. I currently have my antenna directed towards "Little Duval Mountain" which is the Primary site for this area, however I can't pick anything up whatsoever. Am I being too wishful thinking that this will work, or is it just blind luck that this darn thing isn't working?

You can go round in circles trying to tune in a digital signal on internal antennas .

If they are not in the right position there is nothing being picked up for the tuner to "lock" onto.Without a "pretuned" channel ,you can't find where to position them .

If possible,see if you can take your laptop to somewhere where there is a known good antenna (preferably an outside one) ,plug this into your laptop and tune your channels on that.

Once back in your room,you can plug your indoor antenna in and move it around until you find a place where it might work.

My experience with USB stick tuners and indoor antennas is that they suck.

USB stick and many PC tuner cards usually need more signal that Set top box's or TV's with built in digital tuners generally need to work and this is compounded by the fact that indoor antennas generally scrape the bottom of the barrel regarding strong clean signals.

TV signals and in particular UHF ones as you are trying to receive don't penetrate buildings very well.

You may find that an outdoor UHF antenna will work better indoors than some tricky dick indoor antenna but it must be mounted vertical for the transmitter you are aiming for.

Another trick that may help is to borrow an analog TV (or try the analog tuner in the stick if it has one) and see if you can get some analog channels first. Use this to help find a "better "position for your indoor antenna and then try another digital rescan.

Hope this helps ,Bellotv

Thanks BelloTV. I'll see if I can test the signal via the Common-room TV's antenna. Hopefully its pointed towards Little Duval, otherwise I'm screwed. The Eyetv is Digital only, as a Hybrid was well and truly outside of my budget. Other people have been able to connect via Digital cards in my dorm, so here's hoping this is fixable!!

Thank you!!

Evening all,I have been following the forum for ages and now need some advise and assistance....thanks.

We reside in OPeak Hill right behind the open cut that blocks us from Mt.Canobolas.We rely on retransmission here which as present is diguital from Mt.canobolas and analogue to our sets,BUT we have a smart (we think) firey who is going around and pointing antenna north and being able to transmit didital fro notrth somewhere.

I am seeking to know where and who north of Peak Hill is sending a digital signal towards us.We are able to ponmt our antenna north BUT who is ending the signal is it Coonabarabran.Dubbo,Gilganddra or where.I am fuklkly able to turn the antenna as I am able to do the same for many residents in peak Hill.

The ones that live south of the Newell Highway we have successfully pointed antenna towards Mt.Canobolas,BUT the ones that reside north of Peak Hill and have clear line of sight north are missing out.

Can some one advise as to who north is sending out a digital signal,.

UI have GPS so a conmpass reading,or even a location is all I require.

Can some one assist in this.

Thanks heaps

Two possibilities I'd reckon

* Buninyong Hill, north-east of Dubbo (though it is only low power)

* Mt Cenn Cruaich, in the Warrumbungles (which is a high power transmitter).

dkint3,

Thanks for the infor,BUT I feel that at Dubbo,this spot is still now only used for ham radio repeaters,BUT Wurrumbungles is a possibility.....

...I feel that at Dubbo,this spot is still now only used for ham radio repeaters...

According to the ACMA listings, Buninyong Hill does have the full suite of Digital channels (I have no idea whether they would be receivable in your location, however):

----------------------------------

SBS 55 (718.625 MHz) - (SBS)

ABQN 58 (739.625 MHz) - (ABC)

CBN 61 (760.625 MHz) - (PRIME)

WIN 64 (781.5 MHz) - (WIN)

CTC 67 (802.5 MHz) - (SC10)

----------------------------------

All these services are horizontally polarised.

Cheers,

ChaosMaster.

Morning ChaosMaster,

Thanks for your information.I was aware of those outputs as they are also located at Sappa Bulga Rd (same location) as every other TX position for Dubbo.

99% of TV transmission out here believe it or not are vertical,so it appears that we will have to adjust our antenna to horizontal to work.

We have retransmission from Mt.Canobolas which is Vertical for Prime,WINTV,Southern Cross Broadcasting (10) and Auntie (ABC),so will revert back to horizontal.....

Will get onto the roof over the weekend,as I have a couple of amateur antennas to relocate and we shall see what happens.....watch this space.
