Req circuit to record from phone line (UK)

Either

"Lem"

On the line side, add a 0.22uF, 100volt cap and series resistor of 10 kohms, also fit a 4.7 kohm across the winding.

On the output side, use a pot to match the signal to the mic input of a cassette recorder - you can test by making a dummy phone call on the same line.

Keep the transformer away from sources of AC hum.

I find this is quite sufficient...you interpose it between the handset and the phone, by unplugging the handset cable.

Terry, which part of this site did you have in mind?

Check out this months Elektor magazine, there is a design for one in there.

A search term that might help you is "phone hybrid". That's what we call these audio-to-telephone interfaces in the broadcast industry.

If you want to go down this route have a look at

They have loads of products (but not 'inexpensive')

I've used several of the JK Audio 'THAT' range (THAT-1 and THAT-2).

The THAT-2

Has a phono and XLR in and out

The part that says....Record your telephone calls to hard disk

Hum is my chief problem now. Is there an alternative circuit (nothing too complicated please!) which is less likely to pick up hum.

I will be using this near my PC and all the extra wires and devices you might expect.

Hello Lem,

This is what you want from Maplins Electronics in UK

For recording from a telephone, you need low background noise and good balance between the near and far party. Check out
