Something that I tried that works very well on the cable is the use of a
commom mode rejection filter. You can get all the parts at your local Radio
Shack. You will need the following:
2) 75 ohm (coaxial) to 300 ohm (twinlead) transformere
1) 300 ohm (twinlead type) high pass filter.
1) 75 ohm coaxial jumper
Disconnect the cable from the TV or VCR and connect the jumper in its place.
To the open end of the jumper and the now open end of the Cable, commect the
transformers. Now connect the twinlead outputs of the transformers to the
300 ohm high pass filter.
This type of filter breaks the shield of the coax along which most of the RF
from the ham xmtr travels. It was written up in CQ about 6 years ago and
works very well here at WD8LLD. Incidently, the cable leakage
through this filter is negligible due to the extremely short lead lengths on
the 300 ohm side of the transformers (for those of you that are worried
about the guys from the cable company that are now roaming around with the
leakage sniffers).
Give it a try, you'll like it and the total cost ia about 10 bucks!
