DVB-T USB Dongle,Signal Level 100% but Signal Quantity 0%

#1
Im using a generic DVB-T usb dongle which uses A9015 chipset to receive the public digital tv. I download the latest drive for A9015. And the usb device can be found properly. The original software in the package is Blaze. But no channel was searched no matter which antenna(the mini one in the package or the big one for tv set) I use.

Then I switch to ProgDVB using the big antenna. I found the signal level is always 100% but the signal quantity is mostly 0%(sometime,probably one sec or 2secs it's 10% or so). I search the channels but unfortunatley no channel was found either.

So what should I do or what special setting I need to setup.BTW, Im in Australia.
