That would be really helpful. Thanks Dan Could you send me a circuit diagram? That would be really helpful.

The bottom line is, you should have a nice isolation between your phone line and your device. I experienced this once, and I was also curious on what caused it. I used an unused small power supply transformer, and the noise was significantly dropped. You should use a transformer (can be a radioshack telephone trafo or any trafo will do!).

Are you connecting to the normal telephone line? They could have changed their specifications. Maplin might sell some telephone recording devices that should be compatible.

I've built the circuit 3 times also trying smaller capacitors. still no joy. could this be a component issue or line interferance, maybe someone could mail me a pic of how they've done theirs with the output connected. thanks tam. i have exactly the same problem with an NTL line, i get a loud humm noise.

Check your circuit! That’s odd, because it works perfectly for me on NTL and BT. Check your circuit!
