Can hear TV or Radio station via Phono stage ???

The first thing to check is the ground. Make sure you are properly grounded.

Second is the connection.

I agree with other posters that location and connection is first step. I have cured my RFI by tightening connection by just jamming the cables in harder into the integrated amp I'm using....then securing the ground (it had popped out during the process and I couldn't figure out why the tightening was no longer working as it had before).

To me it comes down to flawed design of certain TTs. My stuff is vintage. They probably learned to fix over time.

Ground, ground, ground. Check the ground. Then make sure both tonearm is grounded to phono preamp and then your table plinth (bearing) is grounded to something. If you do these two things, 99% of RF problems will be a distant memory.

If you have a tube amps - replacing the power tubes may be just the ticket as this was the case for me. I had three plus year old New Sensor Mullard EL34's in my int amp and once I dropped in new a new set of matched quads WHAMO no more RF issue.

Are the satellite TV stations scrambled?
