[linux-dvb] Tuning problems

[Ian Roberts <ianwroberts@internode.on.net>]

Dear Linux-DVBers,

I now own two USB DVB-T receivers (dongles): a Gigabyte U7000-RH and a 
digitalNow tinyUSB2.

I use them on my Kubuntu 7.10 workstation.

I've had the digitalNow for a year or so and it has been working fine 
(and easy to get going) with kaffeine except that I couldn't receive SBS 
reliably (in Adelaide, Australia) although I was able to tune to it from 
time to time. With the Tour de France starting next week (coverage 
broadcast by SBS), I took a punt yesterday and bought a Gigabyte 
U7000-RH and, yes, it too was easy to get going, and, luckily, receives 
SBS nicely -but it can't tune to Channel 7 at all!

My kaffeine installation now has a channel list that covers all the 
local terrestrial TV stations. If I connect the digitalNow device, I can 
watch 2, 9, 7 & 10 and if I connect the Gigabyte device I can watch SBS, 
2, 9 and 10.

I'm presuming that means that by channel tuning data is OK. I don't know 
whether it's relevant, but I notice that SBS seems to be the highest 
frequency local station and Channel Seven seems to be the lowest. There  
seems to be a problem with both devices at the opposite ends of the 
frequency range.

Any suggestions? (other the juggling the two devices!)

bye
