Digital TV noise

[atec77]

Why does everything you touch turn to dog shit ?

why after all those years of posting do you have less of a clue now
than a decade ago

oh and the question is rhetorical

No, the one from the hospital. But all of them do it.

I meant the police chopper here

Right now in Campbelltown (Sydney S/West) many of my digital channels
are dead. I get
1,2, 3, 10,11,22,23,24, 32,44
Don't get
7,9,72,73,90,99.
Have often had troubles with 7 group not the others, seems to be
weather/overcast humidity connected/related. Using old analogue aerial
so probably a new digital one would help.
Not realy bothered about it yet. Most of time I get the lot

Yes, you should get a digital aerial.

I live in Kearns, a suburb of Campbelltown, and when I first came, 9-10
years ago, I had a lot of trouble receiving Channel 2 (analogue).
So I upgraded the aerial & no problems since.

In that case, it might be the area. I often loose 9 & 10 grp. now 7, 9,
7 10 groups of channels.

** Campbelltown is 53kms from the transmitters at Artarmon and there is high
ground between.

Naah, if I'm at roof top, I have line of sight, but freznel affects
might kick in.

Consider yourself lucky to get any UHF signal at all.

Same area. The longest UHF TV aerial from Jaycar combined with something
like this
http://jaycar.com.au/productResults.asp?keywords=LT3195&keyform=KEYWORD&SUBMIT.x=0&SUBMIT.y=0

Try using a 3 metre long UHF Yagi on a 20 metre high mast.

Current combination is about 6m from ground.

Thank you for the technical assistance, but frankly, give the general
content on TV these days, I would find it hard to invest the time,
effort and money in researching a suitable mast, then gaining council
approval, then installing it.

VHF should be OK with a fringe area antenna too.

Bit cloudy and snowy at time, but far more reliable than the digital
channels.

I just ran "setup" and those Digital above vanished entirely but get 9
on Analogue?
I will when I feel need arises just call a TV antennae/aerial guy they
should know. Not keen on getting on roof myself

I don't do that. Just put two backets onto peaked end of house(not barge
board) and then put both aerials on top of a piep of thin pipe and
lifted it up and clamped to the brackets. By "lift", I meant used and
acro prop actually.

 

[terryc]

I live in Kearns,

You probably have the best view of the aerials from there. straight
NNE/NE to the aerial through a valley.

There are pockets in the Campbelltown city Area that are going tohave
great trouble.expense with UHF.

OTOH, there is the Mt Ousley transmitter to also examine.

a suburb of Campbelltown, and when I first came, 9-10

Details please?
aerial, mast, you/tv guy?, etc.

 

[terryc]

I get real bad signal disruption every time a helicopter flies overhead
or nearby.

I sometimes get a little noise on 10 (and its other stations) but
nothing as bad as when a helicopter fucks up the signal. Since I'm near
the transmission aerials, it is most likely some sort of disruption
between my antenna and the aerial.

Reflected signal from chopper blades?

Oh, it flies low over your house too? {.

 

[Dr Sir John Howard, AC, WSCMoF]

That's my thinking a new Aerial (I can see Centrepoint on a clear day)
Just can't yet to be bothered

Look a little bit more to the left, the the next set of towers, then LH
side.

I would will get a TV guy to do it from local paper.
Strange that last week I got everything (but always did have the odd
time Channel 7 would disappear) Can't see any changes to aerial still
looks OK?

yeah the bogans run wild around here.. (

** For how long ?

Just brief bursts of "noise" or continuous ?

brief bursts that keep breaking up the picture and sound so you cant
follow a conversation

Not to belittle the OP's and other P's problems, but I find this
thread somewhat amusing, considering the recent mention (in aus.comms?)
that FTA digital TV - i.e. DVB-T - is perfectly fine!

I'm grateful that I have DVB-*C*, while even that gives the - very -
occasional hiccup. If I couldn't have DVB-C, I would get IPTV and only
if my TV screen broke, I would get DVB-T!

Aerial specialist put new aerial on roof; don't know any further details.

** And you also posted:

" the noise often comes between 4:30 and 7:30, but at other times too of
course. "


** This is characteristic of RF impulse noise generated by switch arcing
when lighting and appliances are switched on and off. These switches may be
in your own home or neighbours homes or even street lighting.

It is the MOST COMMON problem experienced by viewers of DTV with inadequate
signals or aerial systems.

If you look at channel 7 analogue, you will see noise burst patterns in the
picture at the same time.

It is the BANE of those living in unit blocks and using indoor antennas.

Well I do have a good aerial <http://ausnet.info/pics/aerial.jpg>system
and use a splitter amp, but I'll check to see what shows on the analogue
channel. mite give a clue. good call.
