When you want to look for the signal strength via the commandline use the tool: dvb-fe-tool. This tool is included with the v4l-util toolpack that isn't standard included within the image.
First: v4l-utils needs to be installed on the receiver. Use the command:opkg install v4l-utils
Then use the command dvb-fe-tool.
The parameters that must be added:
-m: Monitoring
-f: Get the Front-end parameters
value: 0 = tuner A, 1 = tuner B, 2 = tuner C, 3 = tuner D
Then I made a scan for tuner C (value in this case is then 2)
dvb-fe-tool -m -f 2
With gave the results:
root@hd2400:/# dvb-fe-tool -m -f 2 Lock (0x1f) Signal= 0.39% C/N= 54.00% Lock (0x1f) Signal= 0.39% C/N= 54.00%
To stop the monitoring Press CTRL-C
In this case the signal strength is 54% with is good for a cable channel.
A good satellite signal gives the following result:
Lock (0x1f) Signal= 18.93% C/N= 13.97dB Layer A: C/N= 71.00%
