[linux-dvb] SV: Re: Visionplus DVB-T USB strange reception quality...

["Alwin Bakkenes" <alwin.bakkenes@consat.se>]

Hej Patrick,

Thanks for your reply.

However, I am slightly confused. Most reports I read state that the PCI card
is worse than the USB box. However, my results are different.

Your reply suggests that I should more or less give up on this USB box as
well, am I correct? I haven't seen the Kworld one in Sweden and really hope
that this can be made to work using the USB box.

Note that for a "normal" nokia 212T there is NO problem what so ever with
signal strength and SR ratio.

Also, when will the SR ratio be calculated correctly?

Currently the signal strength and the s-n-r is not calculated correctly.
Status, ber and unc are correct.

The Twinhan USB device has IMO the worst quality of all dibusb devices. I
also have the KWorld one and a DiBcom reference device, the reception
strength is much better.

best regards,
