Recommended Posts

Hi,

I recently bought a USB DVB-T Digital TV receiver (model:DTB02), i have a major problem when scanned i recieve only SBS,SBS essential and some channel named ERT sat, So why don't i get other channels(Channel 7,9,10 and ABC)??. I use BlazeDTV player and scan. I live in Melbourne (Oakleigh suburb) and i don't think so there is any problem in signal strength!! Can u help how to get other main channels?? what r the setting to be done to get those channels?? plzz..reply as soon as possible!! thank q!

I'm am in no way at all familiar with your product but the symptoms you describe sound very much like what happens with a regular set top box if the channel spacing is set to 8Mhz steps instead of the required 7Mhz steps, is it possible there are some user settings that are not set to the correct parameters perhaps?

(assuming you have a good antenna etc :blink: )

well!! first of all mine is not a set top box it is a USB DVB-T which i connect from my Laptop!! secondly can u explain more briefly how to set the correct parameters?? i mean to 7Mhz instead of 8Mhz?? thank q!

Or if u r a diyer then just get an LP34HV some rg6 and f-connectors, mix and glue together, hang off the nearest tree and ur done :P

thanks for ur g8 help but unfortunately there is no tree nearby to hang!! :P if there is nearby tree at ur place it would be g8 if hang it for me plzz.. :blink:

Sany,

You've probably fixed your problem by now, but I wanted to tell you I had the same problem today when I received a new USB DVB-T tuner. After playing with it for a couple of hours, I managed to work out that it is indeed a reception problem. The small portable antenna that comes with these devices does not receive low frequency reception very well. That is why you can receive SBS (highest frequency of all the stations in Melbourne). The frequencies you need to receive are:

Ch. 7 - 177.5 MHz

Ch. 9 - 191.625 MHz

Ch. 10 - 219.5 MHz

ABC - 226.5 MHz

SBS - 536.625 MHz

As you can see, SBS is the highest frequency, and hence easier to receive with a small antenna. You will also find that as you improve your antenna (eg. make it longer, or reposition it), you will start to receive ABC, then Ch. 10, and so on until you finally get Ch. 7 (being the hardest to receive).

I was able to find all stations by laying my small antenna across a power cable I had lying on my desk and orientating it in a good direction. It is just like playing with rabbit ear antennas, except that with digital, the signal is either ON or OFF (there is no fuzzy, half reception).

You could modify your small antenna by adding some wire (e.g. coat hanger - very stylish and high tech... :blink: ), or plug your dongle into a regular house antenna.

I hope this helps.

Hi all

Sorry about my previous reply ... that was an accident. I'm glad to find this forum, it seems alot of people have experience here.

I have read this forum and tried things you guys have said. The thing with aerial guy from dba website is not really applied to me, since I live in an apartment in the Melbourne City (So the signal is strong), and my neighbour can receive digtal TV with setup box (using the same building aerial).

However, I use the USB TV Tuner and BlazeDTV player, and can only find chanel 7 and SBS....I have tweaked the setting, changed the bandwith from 6,7,8 MHz and even Auto, maximise the channel scan spread from belom 100 to maximum. I have also tried to play around with Advanced Setting, There were 4 things I can change, the Constellation, Code Rate, Transimission Mode, and Guard Interval, but none of them helps. I found like 48 Channels, and 42 of them are Channel 7!! :D

Anybody could help me or give me some idea of what I can try now....

Your suggestion will definitely be tried, since I'm kinda running out of idea now...

How Do I get Ch 10...I kept getting Ch 7, even when I tried to scan at 711 Mhz mark. ......I use USB Tv Tuner DVB-T

Any help would be appreciated.

Are you sure your neighbour is receiving free to air transmissions using a DVB-T set top box and not via Foxtel etc?

What make/model of USB tuner are you using? Are you sure the building distribution system is designed for the digital channels and do you have your USB tuner connected to it?

The main Channel 10 transmitter is on VHF Channel 11 VHF 219.5 MHz

No, My neighbour that I know did not use USB TV Tuner, They use a setup box TV tuner, and yes it is a digital TV free to air transmission, not Foxtel.

I use WandTV DVB-T Usb Tuner, and after few hours wasting my time on this thing, now I managed to find all the channels, EXCEPT Channel 10. I even tried to call CHannel 10 and spoke to their tech guy for half an hour, and all they could suggest is to try it at different house and different suburb....(so I need to buy a new house to use the USB TV Tuner? :blink: )

I have tried to scan 219.5 so many times, changing all the advanced setting, but I keep finding channel 7 or sometimes none (which is pretty far from that frequency) .... I thought it did not delete properly, so did a hard reset (reinstalling the software and driver)...and just scan that particular freq only, and still getting the same thing...sometimes I get Channel 9 on that if I reduce the bandwith to 6 instead of 7 Mhz.

I didn't mention anything about your neighbour using a USB receiver.

You didn't answer this question : " Are you sure the building distribution system is designed for the digital channels and do you have your USB tuner connected to it? "

It sounds like you are picking up the UHF translators on the Como Building in Sth Yarra.

Depending where you are, this may not be providing sufficient signal.

If you are using a tiny antenna, commonly supplied with USB receivers, they are next to useless. You need to connect to an external antenna, which is designed to receive the digital signals in your area.

Bandwidth for all Australian digital transmissions is 7MHz.

If your neighbour has no digital reception problems, try connecting your USB receiver on the antenna outlet that your neighbour usins on their STB and try your neighbour's STB in your apartment.

Card-type tuners do not generally perform as well as STB receivers.

From my experiences with them, they require more signal than what most STB's need to lock onto a digital signal (and keep it).

I wouldn't expect marvels from a device that costs less than $30.00

Yes the building has digital channels (Checked with the body corp) and yes I have my USB connected to it (I dont use the small aerial)

I'll try to hook up to other aerial socket today, but I would doubt I could borrow his box though :blink:

The device cost less than 30 bucks, ...but it almost perfect, it just that tiny little bit that annoys me. I'm almost certain it's a tunning problem.

Hi all,

Ive also bought a Wand TV USB DVB-T tuner for my laptop, im using a software called BlazeDTV which came with the tuner. When using the little antenna the box supplied, i wasn't able to pick up any channels, so i then connected it to the wall socket, and was still only able to receive 6 versions of channel 7. ive been scanning between 100Mhz - 800Mhz with a Bandwith of 7.

Im not sure what the problem is, as the tv that the wall socket was previously connected to, has a digital set top box connected, so i'd assume that reception shouldn't be an issue. I live in Surrey Hills, so according to the DBA im in the main coverage area. http://www2b.abc.net.au/reception/frequenc...69&presdir=

Ive read through all the previous posts and nothing has worked, tried connecting to a different wall socket, and then to a set of bunny ears antenna (both inside and outside), still no improvement.

Just wondering if anyone else had any more suggestions, or any experience with this device. Any help would be appreciated

Thanks

Sami

Hey ive jsut created this profile so that hopefully someone out there will understand what this problem is and how to fix it. Only difference between yours adn mine is that you ve actually gotten a chanel and ive not even achieved that, ive tried most ideas shown on this forum and are starting to get really annoyed at the cmpany who sold me this (nebulahk - Ebay store) ive got the same software and same hardware as you and there is no way in hell my computer doesnt reach the minimum system requirements (80Gb HDD, 8800Gt Alpha dog edition, dual core amd, 2.5gbs of ram).

I live in perth and my friends and neighbours all have digital tv tuners and their reception is perfect (they have the cards not the dongle) and they live in the same suburb as me.

I believe the main problem with this program could be the bandwidth option. as i have seen through many posts and comments most people have mentioned that the bandwidth in australia is from 3+ but the software (BlazeDTV) Doesnt give u the option for a lower bandwidth than 6. Am i wrong or right? can someone please help me b4 i loose it, would be much appreciated!!! :P

Hey Craig..not sure how the Melbourne Area can help..maybe if you went and posted this in the Western Australia, Perth Geographical Area, you might get someone local to help you out.

Cheers mate..good luck with your prob. :)
