I prefer it when networks do this. Case in point WIN’s ridiculous naming.

Just to clarify (for my list website), is the name definitely no longer in all-uppercase?

No, it’s still in all-uppercase.

Yes sorry, case sensitive it is

Lol! Clearly at least one person in this country thinks that analogue TV still exists! I’m sure there are others :smile:

If only it did, it was either the superior technology for a country like Australia or DTV has been poorly implemented here. A bit of both I’d say.

I would lean more towards “poorly implemented” in that I see the main issue being that too much bandwidth has been sold off for 5G, creating difficulties for blackspot coverage particularly when caused by co-channel interference.

Also that we went for MPEG2 too early, and we still haven’t done anything about mandating a move to MPEG4, which should have been done by now.

DTV is great when it works though.

Yep, I agree. It was a good move to mandate widescreen from the very start, but I think we got in a bit too early with HD. That shouldn’t have launched until the late 2000s or earlier this decade when MPEG4 transmissions were starting to become a thing around the world.

While Digital TVs and set top boxes were originally VERY expensive, the decision to place restrictions on multichannels in a bid to protect Pay TV did very little to grow digital terrestrial television in Australia with many regional areas still only having access to analogue services (or limited Digital TV compared to metropolitan markets) for years!

Having said all that, I think Australia becoming a Digital TV-only country was an inevitability no matter which way you spin it.

I’m having a bit of a problem with my TV reception at my home near Campbelltown, at least on the living room TV.

On my 55" living room TV, I lost Ten (VHF-11), whilst the ABC (VHF-12) has a weak signal. Seven (VHF-6), Nine (VHF-8) & SBS (VHF-7) are received fine. On the bedroom TV, using the same antenna, all the channels, inc ABC & Ten, are received with 100% signal strength. As you can tell by the frequencies, both TVs receive the signals from the Artarmon/Gore Hill/Willoughby towers.

What could be causing the problem? Is it the cable that connects to the living room TV that might need replacing?

At least I also have the option of realigning the antenna towards the Razorback TV translator, which retransmits the Sydney channels.

UPDATE: ABC is back to good strength, whilst I’ve got Ten back. I’m still at a loss as to how it happened though. :confused:

That’s a bit unusual.

Does it happen often?

No, it’s the first time this happened. I’ve had the living room TV for 6 years, and up until tonight, never had any problems with any channels received from the main towers.

In case anyone is wondering what antenna I use for general TV viewing at home, it’s the Matchmaster 01MM-DG30, which was installed in April 2011, when analogue TV was still transmitting (my household still had an old CRT TV in the living room) & before the Razorback DTV translator came online, which occurred in around April/May 2013.

I can only wonder if the cool windy change had something to do with it now that it’s back?

It’s possible, but since the bedroom TV that is connected to the same antenna was unaffected by the loss of Ten & the weakening signal of the ABC, it seems unlikely. Although it’s quite a coincidence that it affected the higher parts of VHF Band III (11 & 12), whilst the lower parts (6-8) was pretty much unaffected.

Do you have a masthead amplifier?

No.

Shouldn’t need one out near Campbelltown… it’s not exactly Sticksville.

Is the bedroom closer to the antenna? (The actual cable run) … the longer the coax the weaker the signal.

There’s also a correlation between temperature and the signal strength from the transmitter… I cant remember which way it goes, but in colder (or hotter?) weather the signal has to work harder to reach you. Which is why it’s probably only happened today.

Nine times out of ten it will be the cable - check all terminations, junctions, etc.

If you’re really keen, next time it happens, swap the TV’s over and see if it still exists… it might help isolate the type of fault to the TV, or a nearby interference source… have you bought any new appliances lately? What about the neighbour?
