TV giving bad reception
Using rabbit ears works fine around here, but recently channels 2-5 are too
snowy to watch, channel 7 is sometimes OK, and channels 8-88 are fine. All stations have transmitters on the same mountain, so I'm thinking the problem is with either TV or antenna. I have moved the antenna all over the room and get some slight improvement but not much. Anyone seen this before and know a cause of it? (I have also put a different rabbit ears antenna on the TV and same results.) Thanks in advance. Fred |

try an an aerial with built in gain amplifier (ideally with a varialble
dB control). try with another tv to be sure yours doesn't have a bad tuner |

Weather doesn't have an effect, but will look at the truck situation here!

Seems a lot of devices' SMPS's these days generate lots of hash into the powerlines that gets radiated and is easily seen in DX reception. A*s*i*m*o*v .... Reactance: your imaginary friend. |
