iamreal2 Posted March 29, 2007 Posted March 29, 2007 Hi All, I got a WandTV USB DVB-T stick recently. I use it with the portable antenna that comes with the device in my room(an appartment), and am able to get 219.5/226.5/585.5Mhz (TEN/ABC/SBS) successfully but NO 177.5/191.5MHz(7&9) at all. When I plug it into the wall socket(connected to roof-top antenna of the appartment building), I got 177.5/191.5MHz found by scanning (using BlazeDTV software). The weird thing is, when I just open the software, the signal LED on the USB stick light up and software shows great signal quality. BUT it only works for about 5-10minutes for the first attempt and suddenly, the signal quality goes to nothing and the LED on USB stick goes off. After closing the software, I open it again, it plays for another minute or so and dies again, and so on. Everytime it plays for about 1 minute... All other frequencies are working fine. I've tried nearly all antenna availble at DickSmith with no luck. This was before I observed the above behaviours. It will be very much appreciated if anyone can give me some possible reasons for the above. Is it a problem with : 1. the antenna? 2. the USB DVB-T stick? 3. the BlazeDTV software? Thanks in advance. Cheers, Jason

andrew1503559519 Posted March 30, 2007 Posted March 30, 2007 You may have 2 issues here. Firstly in Sydney Nine is on 191.625. Both PCI cards that I use and the inbuilt tuner in the laptop had to be manually told about the non-standard frequency before pictures would appear. Until then all I got was excellent signal strength but no picture. Secondly a number of USB ports can't sustain the power to run a tuner for long. You may need a powered USB hub. A number of Dell machines and many laptops have this issue according to forum posts some time ago.
iamreal2 Posted April 2, 2007 Author Posted April 2, 2007 Thank you both! It's due to overheat. When I use a fan to cool it. It's working fine with the blue LED constantly on and signal quality full scale all the time. I tested for a few nights. It's confirmed to be the heat problem. I'm sending the unit back and getting a refund. Considering a Leadtek DTV dongle which is based of DibCom7700. Though much more expensive, I got reliability and decent design. What do you think?
