My outdoor arial is quite misaligned, and I'm going to realign it to get better signal quality.

Is there any good and simple programs to use to show the dvb-t signal strength from my Asus p7131 dvb-t tuner? Anything that shows the signal strength on the fly would be good, but something that can show for a particular mux would be perfect.

I tried that the first time. Prime was crystal clear, but freeview is almost unwatchable.

talsemgeest: I tried that the first time. Prime was crystal clear, but freeview is almost unwatchable.

Why was it unwatchable?
It either works perfectly or not at all.

I think the problem is the lack of hardware acceleration. What graphics card do you have?

I definitely have hardware accelleration. I just bought myself a Nvidia 9600GT, and cpu usage only goes up about 5% when watching tv (when it does work).

Tv is like sky when it is about to go into rain fade, going pixelated, sound dropping out, screen going green etc...

You using powerdvd for hardware acceleration? or another codec?

This has been covered in another thread. Here's what I cam up with;

I found one eventually. Dos based and all command line but does seem to work. It's at
http://nate.dynalias.net/ScanChannelsBDA/ScanChannelsBDA.html#SC2007

Run it and add channels (using option 1) as follows
538000
then at the next prompt enter "8" Mbs
press 1 to add channel again
570000
8 Mbs again
press 1 to add channel again
666000
8 Mbs

These are the channels for Waitara, you can easily enter your local channels from the sticky topic "NZ Freeview HD Guide" in this forum.

Then run option 2 "Generate Channels.ini"

I got a resulting output on screen;

# locked 538000, 8 signal locked = Y present = Y stength = 51 quality = -100

Program_ 1("Radio NZ National" , 2000, 0, 620, 220) # LCN=50
Program_ 2("Radio NZ Concert" , 2001, 0, 621, 221) # LCN=51

If you use Option 4 you can enter a specific frequency, like 538,000 above and the * Mbs bandwidth and then see it displaying signal quality and strength as a new line every second. You can watch this as you adjust your antenna, boosters etc and see the effect in real time.

I noticed it starts at about quality 10 and then goes to 40, then 60 and holds there. Seems it takes a second or two for the Nova T to lock in on a frequency.

So clunky but it works!

Here's my experiences with ScanChannelsBDA_UK: http://www.geekzone.co.nz/forums.asp?forumid=83&topicid=22349

I liked the graph that this utility produced in real-time, only problem is I'm not sure it will work with a Asus DVT-T?

At any rate the utility can be found here: http://www.wintvcd.co.uk/tools/ScanChannelsBDA_UK.exe

That is even better, and perfect for my purposes. It is working brilliantly with my card, and seems very accurate.

Thank you very much for your help.
