| You really should have a good r.f. ground. Your wiring in your house is a great antenna and can bring r.f. back into power supply. To narrow the problem, try a battery to the rig(if you have one) instead of p.s. This will show if r.f. is getting into power supply if problems goes away. The real problem probably is the ladder line inside the house. If you run coax to just outside the house, and connect the ladder line there, you should not have any r.f. inside. If the problem is the p.s., you can try chokes on both the ac and dc lines., Tom |
