Question about Televison & Video

1 Answer

Would you confer with me on this couple in Australia

Hi,

Would you look at this post I responded to regarding ABC channel reception on a DVR with tuner sold in Australia. Apparently the LG model built in antenna is notably weak at capturing ABC channels. I read of someone who built his own antenna, placed it in the Attic (or whatever you call it in AU).

Its my guess there must be someone selling decent antennas in the market where you live and giving this couple some pointers would be nice.

Thanks,

    Would you mind if I just copied and pasted your reply into the Solution with attribution to you and your user url here at FixYa?

    Or, if you would rather add your own reply into the Solution that's fine as well.

    What you wrote is very good, but really pertains to an AU TV user's experience. Things aren't that much different here in the US, our FCC allocates band, bandwidth and channels in the band. They just got through auctioning off a frequency and channels in the 5.8GHz area for WiMax which is a pretty cool way of getting 3G broadband on a handheld by hopping across other devices on an encrypted channel of the frequency. These will be express card inserts for laptops as well. Sprint won the auction with a company called ClearWire here in the States and Google is working with All Tell for the same thing to get 3G WiMax to the masses on the cheap.

    Here where I live in Nevada we have more mountain ranges than the rest of the US combinedl. As a result every town has translators and a TV Hill. As a UHF and VHF network it is really impressive to see how these broadcasts are propogated across the state.

    I'm still a bit on the fence with WiMax. It looks pretty good on paper, but the Spec for it seems to get tossed back and forth. So, who knows how many iterations the Spec will have before its actually stable. But, it is a great hope for the masses, especially when you get down into the massive 3rd World countries around the globe.

    Thanks for your permission.

If they are looking for analog ABC, it is low band VHF, ch2 to be exact,where the rest are high band VHF, and needs a decent multiband antenna to get it in alot of areas, well in Brisbane at least. We have Mount Coot-tha that has a good propagation to most metro areas approx 40km radius, although it starts to get a bit noisy on the ABC due to lowband interference issues. .
There are many areas of AU that use UHF for TV also. Not enough hills in many parts of the east coast to get the coverage, so there can often be UHF translators that you need to tune onto. I suspect the ABC problem does relate to them not using an antenna that is suited to VHF, saying this of course if they get the other channels (7,9, and 10) ok.

Go here for a more specific channel/frequency guide to determine if it is the problem by location. ABC is on different channels almost depending on what suburb you are in for some areas. If the DVR can do digital, then they should go that way as it is now UHF ch21. It may be that they are trying to get analog signals, that will be turned of in the near future... so tuning the system in for UHF propagated digital is the way to go.

Back in the day when I used to do antenna I recommended the Hills PF11 antenna, multiband 11 element yagi with low/high band VHF/UHF, or a PF17 (17 element) with mast head amp if they are in a marginalised signal area. But a UHF array is still the best way to go if they can process a digital signal. Hope that helps :)

    oh and the spurious harmonic auto tune may well be the issue, just that ch2 reception has been poor for so many people over the years, will be good to see it finally turned off!!

    cut and paste at will ma man... :)



    Its an expanding market here in Au with wireless also. The comms co I service managed for missed the boat in my opinion having so many hill top comms sites, they stuck with the 2 way radio, and didnt get into the WiMax bandwagon. Making most of the revenue from mining industry and the MPT1327 trunking network. Good reason for me to get laid off in the end I guess. 65 yo Managing director could not see a future in internet access for his 30 years in the two way/comm site service industry.

Lost ABC channels on retune, how do I regain reception


Try manually entering the channel number. Many TV's have, besides autoscan, a way to manually add or remove channels.

We're in Australia. When we scan for channels via PS3 Play TV we can't get any ABC channels (we do through our normal TV). How can we fix this please?


I am presuming you purchased it in Australia.
If it's under warranty, take it back.
If it's not under warranty, take it back anyway.
You could argue that as it is not able to tune all Australian stations it is of Unmerchantable Quality, use those specific words, meaning it was not good enough to be sold.

Alternatively you could locate your local Sony service center here;

I would hope that you will be able to resolve it without politely inquiring if the media would be amused to hear about a TV tuner sold in Australia that couldn't tune Auntie. Er, i mean the ABC, mate

If you are receiving the signal from the same cable service provider rather than through an antenna, I would suspect the cable service is having a problem with its retransmission of the ABC channel in that suburb. I don't know if Australia is still broadcasting analog TV signals or if ABC is digital, but if the latter, perhaps the receivers are having trouble decoding the sound format identifier information. This could be something as subtle as a timing tolerance issue or as crude as noise or low signal level on the cable that has the receivers operating at the margin of sensitivity.

When auto tuning my LG LST-5403P dvr I can not get the ABC channels. It worked correctly until my wife decided to go thru the auto tuning process!!! The missing channels can be picked up at the TV but not...


Hello,

The ABC channels arrive on a different Harmonic than Analog signals; specifically the third Harmonic. When you auto tuned, the auto tune chip looks for stron analog channels on the first harmonic and any other strong signals. However the LG model is notably poor at capturing 3rd Harmonic signals.

Harmonics are different frequencies where the same signal can be captured. Making this overly simplified: a frequency multiplied by 2 is a harmonic and that multiplied by 2 is also of the same harmonic; inversely dividing by 2 and 2 gain and so on finds harmonics down in light wave frequencies.

You may be able to manually tune these ABC frequency channels manually (I do not know, as I live in the US and have no direct experience with this) and then add them in one by one. But, using the Auto Tune feature again will wipe those out. The same thing happens to other weak signals, which harmonic is actually (its on an offset carrier wave).

I just read of a man who built an improved antenna and put this in his attic and received ABC channels quit well. A decent understanding of Antenna physics is required, but it only took up 1.5m wide by .8m (sic) long. In a nutshell he improved his basic antenna by building his own more sophisticated antenna.

Shopping around and asking in the shops should get you an antenna add on that will work for you.

As I stated before I live in the US, and we don't have this, but I and others here at fixya have various experience in amateur radio.

I will ask a friend of mine who lives in Australia to confer with me on this problem of yours so he can add some value to our response to you.

Worldvet

How to build an indoor dx fm only antenna?


Hi lgcphoto

What you need is a folded dipole that can be easily made from 300 ohm TV ribbon. Here is a link to a site that gives you instruction on how to make one. You need to check also what way your favorite FM station is polarised. In Australia, some(one at least) ABC stations are vertically polarised(meaning the antenna has to be vertical), presumably for better Car reception. But the majority are horizontal. Great results can often be achieved by splitting the signal from an external VHF TV antenna, but only if it is VHF, and the station you are looking for is in the same direction as the TV repeater. If you need any more assistance with this, just let me know. Rating this FixYa is a great reward for my time to address your request. Cheers, happy DXing
