If you suspect you have signal strength or SNR problems, some steps you could take, if you haven't already, are: 1. Ensure you are using 75 ohm splitters that cover your desired frequency range (55 - 802 MHz for US NTSC broadcast IIRC). 2, Ensure that all unused cable runs, wall jacks, or splitter outputs are properly terminated in a 75 ohm load. 3. Replace RG-58/U cables with RG-6/U cables. RG-6/U has about 3 dB less loss per 100 feet at 400 MHz than RG-58/U according to one manufacturer. 4. Add a broadband TV amplifier as close as you can to where the signal comes into your location, ideally before any splitters or long cable runs. If you don't also use your cables to receive FM radio signals and the amplifier has an FM trap, set the FM trap to "IN" to reduce intermodulation products induced in the tuner by the FM broadcasts in the 88-108 MHz band. 5. Make sure you have an in-line lightning protection/grounding unit installed in the cable close to where the signal comes into your location. Grounding the shield of the coax protects your gear from electrical transients induced by nearby lightning, and it happened to greatly improve the signal quality in my home. > > Below is the output of dmesg | grep ivtv.

But again, the all the init messages are required to be sure. -Andy _______________________________________________ ivtv-users mailing list [email protected] http://ivtvdriver.org/mailman/listinfo/ivtv-users
