Scott, usually an L pad made of two resistors will likely work. I suggest
starting with a 10K series and a 1K shunt on the line from the receiver to
the laptop. The 1K value should be on the end to or at the laptop. If that
doesn't provide adequate attenuation, increase the series resistor. I've
made several of these and have found the space inside a sleeved RCA type
connector adequate to put the two 1/8 watt axial lead R's.

Subject: [TenTec] Audio Pad for RX-340 -> Laptop?
It appears that there is line audio output available at J8 on the rear
cabinet. I want to feed audio to my laptop for digital modes, but the
computer does not have a line input, just a mic input. I believe some
attenuation might be necessary. Any recommendations for values to use
in such a pad?
Thanks.
