DM500c ch*rus cable manual transponder scan unable to lock onto channels

Hi everyone,

I'm using dreambox 500c but cant lock into any channels. For the manual scan I have been trying a range of frequency's. I have the symobl rate set to 8 (see below)

<transponder frequency="**" symbol_rate="000008" fec_inner="3" modulation="3"/>

I still cant channels, even the test channel. My line in is perfect, I can see the noise ratio coming up... i even tested the box on another cable but still no lock!

Any ideas?!

 

Have you flashed it with the latest image? Have a look here

 

The image isn't the problem, its the frequency and symbol rate I am having trouble with.

 

Also, I'm in the limerick city area... would this affect my symbol rate?

Regards,

 

Try

<transponder frequency="323000000" symbol_rate="6875000" fec_inner="3" modulation="3"/>

 

Thanks for the suggestion but unfortunately that didn't work either!

I'm using DM500c
Frequency - 323, 312, 296MHz ... plus many more
Modulation - 64QAM
FEC - AUTO
Symbol Rate - 6875
USE ONIT - No
USE BAT - No

I have tried a combination of these settings with three different image. I am receiving a signal to noise ratio reading so there is feed coming in!

Could I just be getting the wrong combination of settings?! I'm in limerick city!

Any advice appreciated...

 

Go to manual scan and try 00322, 00323 and 00324 for the frequency. You have to type the 2 leading zeros. Same for the symbol rate. You have to type 06875 at the menu with one leading zero.
Enable additionally network search, BAT and ONIT.

 

Thanks again for the suggestion Mgb17. No luck though! Tried settings (incl. leading zeros), and nothing! Its a little strange... I cant even pick up the test channel, RT€1.

I'm stumped!!

 

Are you sure your cable feed is alive and it is true cable?

 

Hi,

Things have changed somewhat since my last post, I made some real rookie mistakes . I now have a DM600c, which is working perfectly to a point.

I can view about one third of channels. I cant view movies, sports or rte 1 and 2. My manual scan configuration is as described.

Constellation 64 qam
Bandwith 8mhz
Coderate ½
Guard 1/32
Transm mode 8k
Coderate 2/3


And i have tried these frequencies

274.000
282.000 - 9 services scanned
290.000
298.000
306.000
314.000
322.000
347.000
339.000
355.000
363.000
371.000
378.000
386.000
394.000
410.000
426.000
444.000

All help really appreciated! Thanks in advance!!

 

oh... and i'm in limerick city area

 

Switch to a working channel, go to manual scan, enable network search BAT ONIT. Let all other things unchanged. Start the scan.

 

thanks a million!
