MySwitch is now indicating the retunes for both CTS from 30 to 33 and CTQ from 38 to 28. No separate date is listed so I'd imagine that means that they will be switched at the same time as the SBS UHF digital service stops.

Have either of the channels in Adelaide restacking in a week done anything on air or in the papers about rescanning yet?

Yes, 44 Adelaide is running occasional ads on air with a simple message about rescanning on 3/5/2013. I have been told that SBS has run some on-air ads as well, but I have not personally seen these. We are getting the generic DBCDE "Roy the remote" ads as well, but these don't actually contain any information, such as channels or dates.

Regards,

Will

SBS ONE is running "crawler" ads across the top of the screen at the start of each program. No dates or channels are given. It just tells viewers to rescan when they lose SBS and gives the restack web address and switchover phone number.

So how did this go today?

Everything seemed to go as planned. 44 Adelaide went off RF channel 30 before 8:35 this morning. SBS was still on RF channel 33 a little before 9:00 this morning. This evening, SBS is on RF channel 7 only and 44 Adelaide has taken its place on RF channel 33.

There has been no decision on this and all community TV licences run out at the end of next year when the restack wil be completed.

The problem is who is going to pay for new VHF transmitters. Hopefully their power will be the same as all the other broadcasters and that translators in the licence areas will be equipped also. Unless the broadcasters can get sponsorship for this it will require government funds.

Isn't Ch 44 meant to go VHF 10 under the restack plan?

(emphasis mine)

Well, there's a change of heart - some may even say "backflip".

Here's what you had to say the last time it came up, and we were trying to explain to you that no decision had been made about CTV channels moving to VHF. I'm quoting your post here directly, to ensure the edit fairy doesn't nip back and change the original:

What a load of rubbish.

I was alerted to the VHF allocation of Main community TV transmitters by the Head of Community TV at the ACMA, not some random ACMA engineers. Not Google.

You used to be so sure!

Making assumptions leads to errors!

Indeed. So, apparently, does lying.

At least some of us are prepared to admit our errors when further evidence - or reality - proves us wrong...

Hi All.

Am brand new to this and still need to find my way around. I was originally looking for some asisstance and some information. I cannot find anywhere to ask a question, so I have just followed this thread to the end, and hope someone could point me in the right direction. I live in the Lockyer Valley almost exactly half way between Brisbane and Toowoomba. I have a new antenna, quad shield cable and a Kingray masthead amp. I can receive some channels consistently, ( all channel 2 and SBS) but not all the time. I cannot tune to Brisbane or Toowoomba 10 or 9 either manually or via autoscan. The tuning process tells me I have signal strength approx 8, but gives no reading for signal quality. I can tune to Bris and Toowoomba 7 channels sometimes, but never get consistent reception, frequently dropping/pixelating. The myswitch map tells me I have "variable" reception from both. Until about 10 months ago (give or take) I could receive all Brisbane stations, with little trouble unless there was poor weather. Now every time I turn the tv on, I have to retune, and then it seems a lottery which stations I will pick up. I just wanna watch the footy!! :-(

Will this "restack" make a difference? Is there something I can do? BTW... I have enjoyed reading the the conflicting opinions and ongoing "banter" between Alanh and everyone else.....

I do apologize in adavnce if I have come to the wrong place to find these answers. I do have other questions and it seems you guys have the knowledge to shed some light.

Cheers, Gusman.

Brisbane is one of the transmitters that has already had the restack, which meant SBS moving down to VHF 7. Which seemingly was fine for you either way. Nothing changed which would make a difference for the Nine and Ten services from there.

The restack of the Toowoomba transmitter around this time next year might assist as it will bring the channels down to lower frequencies, which are typically easier to receive (less cable loss for example). On the Toowoomba transmitter, WIN (Nine) and SC Ten are currently the highest frequency; along with Toowoomba's SBS - I assume you're getting SBS from Brisbane, but unless you can find the frequency display when tuned into one of the SBS channels, it's not easy to tell; so them going down to lower frequencies might put them on the right side of the digital cliff.

A sudden change from 10 months ago might mean that there's a localised source of interference - how long ago did you get a new antenna? Might also be worth asking your neighbours if their TV reception is good and looking how their antennas are positioned.

Otherwise, if you can't get all the channels for your area (in the case of the Lockyer Valley, that means the Toowoomba ones) - you can apply to receive them via VAST satellite instead.

If you wanted to know, the correct place on the forums would be: http://www.dtvforum....hp?showforum=34 - though the last posts about the area are from 2005.

There are 3 low powered translators in Toowoomba are only designed for the City and not down into the Lockyer Valley. The main transmitter for the Darling Downs is near Dalby which will be of little use to you. Guzmann, you don't say what type of antenna you are using nor the model of masthead amplifier. If you want to use VAST then you will have to get an endorsed installer http://www.digitalready.gov.au/how-to-switch/helpdesk/endorsed-antenna-installers to measure the signal strength at your place. The installer has to submit the technical details because the commercial TV programs are encrypted and you will not get access unless the signal strength at your place is low enough. Remember that the commercial programs are 7 Central, Southern Cross and Imparja not the Brisbane stations. The installer may be able to improve your reception. http://www.digitalready.gov.au/what-is-the-switch/digital-tv/viewer-access-satellite-television-vast . If you do not watch Bris 31 community TV then a Hills Dy14 antenna is the most sensitive for all other stations. Alanh

One of which is, in fact, a fairly high-powered translator designed to also cover large parts of the Lockyer Valley...

The main transmitter for the Darling Downs is near Dalby which will be of little use to you.

To people unfamiliar with the region, this is a typical example of Alan Hughes providing a totally irrellevant 'fact' : one which, on the face of it, sounds useful, but in reality has absolutely nothing to do with the issue.

From Gusman's rough location, Dalby is approximately 1 1/2 to 2 hours away by car, separated from him by a continuous mountain range ~2/3 of a kilometer high, and in a totally different geographical region. There are at least 4 transmitter sites closer to him, of which at least 2 have been designed to provide at least some coverage to the Lockyer Valley, and another one which is specifically designed to cover a part of the area.


Alan, I have I think been exceedingly polite to you for many years now. I've tried many times to engage with you and others to discuss many of the finer details and more technical points of your posts. At best you ignore and continue to post the same rubbish; usually you argue and continue to post the same rubbish, at worst you belittle and abuse - then continue to post the same rubbish.

With your above pointless post, I've reached the end of my tether for the time being.

Alan Hughes, you are a complete f***ing idiot. I can only assume that you're such a f***ing idiot you don't already know that, because the alternative - that you know you're a f***ing idiot, but continue to post wrong information and pointless crap anyway - simply means you're an irresponsible or malicious f***ing idiot.

If this comment gets me banned or suspended, so be it...

I mentioned the previous discussions of reception in the area, it's an improvement over previously

DenaJ,

It is worth a try. It should be the right band. Just remember that Toowoomba is 1.25 kW power at 42 km (Antenna direction 280 degrees), but the Darling Downs transmitters are 500 kW power at 111 km (Antenna direction 316 degrees). Both require the same type of antenna. If this set up is not satesfactory, replace it with a UHF phased array mentioned in my post. Generally the higher the antenna the better.

AlanH

So with the passing of 8 years, at least now it's just an irrelevant fact instead of an active suggestion - perhaps in 2021 he might not mention it at all. Progress!

Just try this for size

The Darling Downs transmitters 500,000 Watts each on UHF band 4

Brisbane 50, 000 Watts on VHF = 200, 000 Watts on UHF band 4

Toowoomba 1,250 Watts on UHF band 5 which needs even more power to be equivalent to band 4

Toowoomba East 200 W which also overlooks the Lockyer Valley because I have seen it along with the Toowoomba transmitter above.

I would say that 1250 Watts doesn't cut it!

Alanh's first two sentences above suggest that reception cannot be expected from Toowoomba down into the Lockyer Valley. But is that true?

1. A town in the Lockyer Valley somewhat nearer to Toowoomba than Brisbane

This evening I accessed the http://myswitch.digitalready.gov.au/ site and placed the marker on the little town of Plainland, in the Lockyer Valley, on the Warrego Highway. Plainland is located a considerable distance, about 46km, from Toowoomba, and a rather greater distance, 60km from Brisbane.

Myswitch then provided this information:

Good coverage

14400/Television Translator Site Video Ave Mount Lofty TOOWOOMBA

Lat (GDA94) -27.54319443

Long (GDA94) 151.970352

Service

Network Owner

Freq(MHz)

Channel

Polarisation

Pat

Licence No

ABC ABC 718.5 55 H OD 1158181

SBS SBS 802.5 67 H OD 1158438

RTQ WIN 781.5 64 H OD 1158294

TNQ Southern Cross Austereo 760.5 61 H OD 1159384

SSQ Regional 7 739.5 58 H OD 1157769

So it appears that reality disagrees with alanh. According to myswitch, the television translator site at Mt Lofty provides "good" reception almost half way down into the Lockyer Valley at Plainland. And Gusman has stated he is half way down into the Lockyer Valley. So for him the Mt Lofty station is relevant to consider. This is confirmed in his post where he reports what myswitch has stated for his location:

I live in the Lockyer Valley almost exactly half way between Brisbane and Toowoomba. I have a new antenna, quad shield cable and a Kingray masthead amp. I can receive some channels consistently, ( all channel 2 and SBS) but not all the time. I cannot tune to Brisbane or Toowoomba 10 or 9 either manually or via autoscan. The tuning process tells me I have signal strength approx 8, but gives no reading for signal quality. I can tune to Bris and Toowoomba 7 channels sometimes, but never get consistent reception, frequently dropping/pixelating. The myswitch map tells me I have "variable" reception from both. Until about 10 months ago (give or take) I could receive all Brisbane stations, with little trouble unless there was poor weather.

From Gusman's post his location is classed by myswitch as being in an outer fringe reception zone both from Toowoomba and Brisbane. However until 10 months ago he could usually receive all Brisbane stations. If the reduction in reception from Brisbane is not attributable to local interference it may be attributable to increased tree foliage blocking the signal or a new building blocking the reception or causing an unfortunate reflection.

Presumably a slight improvement such as a taller mast or different location of the mast or a more directional antenna might be sufficient for consistent good reception either from Brisbane or from Toowoomba. A local TV antenna installer would no doubt be able to advise, and/or take measurements, and as GoForMoe mentioned, neighbours may have some helpful information.

What was not particularly helpful was alanh's suggestion not to expect reception in the Lockyer Valley from Toowoomba. As I mentioned at 1 above, at Plainland, well into the Lockyer Valley, reception is classified by myswitch as "good" from "Television Translator Site Video Ave Mount Lofty TOOWOOMBA".

It is unfortunate that alanh persists with less than accurate advice even on his specialist topic of antennas and radio and television reception. I can only assume he does very little research before he types to provide advice to other forum members (including advice he gives to newcomers such as Gusman).

BTW... I have enjoyed reading the the conflicting opinions and ongoing "banter" between Alanh and everyone else.....

Unfortunately the ongoing "banter" between Alanh and the other contributors can lead to exasperation!

MLXXX,

You can go to the Picnic Point Park as I have and see the whole Lockyer valley from the Toowoomba East transmitter site, but as I said 200 W is not sufficient. the 1250 W power in Television Av is also tiny compared to the power coming from Mt Coot-tha the equivalent of 200,000 W and he says his location is half way between.He says the digital ready map says his reception is variable so your location is not where he is. More useful information has already been posted.

Alanh,

the myswitch site indicates there is good reception from Mt Lofty out to Plainland, which is a substantial distance into the Lockyer Valley. It appears Gusman resides only a bit further to the East. Importantly he is already receiving some TV reception from both Brisbane and Toowoomba. A slight improvement in antenna positioning may he sufficient for reliable reception from either direction.

I might mention I have been to Plainland and observed what looked like UHF antennas on a number of the dwellings.

Although the power from Mt Lofty may be small , it appears to have been adequate for penetration into a substantial portion of the Lockyer Valley.

The Darling Downs transmitters 500,000 Watts each on UHF band 4

Brisbane 50, 000 Watts on VHF = 200, 000 Watts on UHF band 4

Toowoomba 1,250 Watts on UHF band 5 which needs even more power to be equivalent to band 4

Toowoomba East 200 W which also overlooks the Lockyer Valley because I have seen it along with the Toowoomba transmitter above.

Alanh

AlanH, you are commenting again on people in my patch and I don't like that except of course that it provides me yet another opportunity to demonstrate that you are simply a Googler and have no involvement in radio or television broadcasting in this country.

Anyway................Oh dear AlanH........................this is just getting to easy to advise the reader how little you understand.

Never mind, just for the edification of the reader we'll have a look at AlanH's statements above one at a time, it's a bit sad to show him in such a bad light however he is so deserving of such treatment. My disappointment is that it's not much of a challenge which demonstrates he's not only a bit of a dummy, but also he doesn't learn.

Please note I'll play this game by inviting AlanH to answer a simple question or two on each of his "Just try this for size" statements.

(1) The Darling Downs transmitters 500,000 Watts each on UHF band 4

AlanH, what is the antenna pattern for this site and what is the ERP directed to Plainland?

Brisbane 50, 000 Watts on VHF = 200, 000 Watts on UHF band 4

AlanH please tell everyone why 50kW on VHF = 200kW on UHF BIV

Toowoomba 1,250 Watts on UHF band 5 which needs even more power to be equivalent to band 4

AlanH, explain your claim above and later I'll explain why you are wrong.

Toowoomba East 200 W which also overlooks the Lockyer Valley because I have seen it along with the Toowoomba transmitter above.

AlanH, no reputable broadcaster or at least any broadcaster who knows of your reputation here would permit you to enter a transmitter building so you can't mean that you have seen a transmitter. Most likely "seen" means Google Earth.

Dear reader, please note AlanH will not respond, the next stage for him is to go away and be annoying somewhere else, don't knock it, I mean to say, that really is rather good.

To put the situation simply, Mt Lofty is line of sight to Plainland, Mt Coot-tha and Mt Mowbullan aren't by a long way. People in Plainland with resonable antennas and masthead amps would be able to receive Mt Lofty even if they reduced transmitter power by 3dB. With care 100W ERP on BV UHF line of sight can be received 90km away.

AlanH wouldn't know this because he would not be able to find this on Google.

Note just for the record, AlanH has no experience and no involvement with any radio or television broadcaster in the country.

James
