B & W (Waters) Universal Hybrid Coupler II, Model 3002
This IS more than a phone patch. This coupler provides all the
switching possibilities to record or playback your telephone
conversation or on-air QSO through a tape recorder or sound card (if
you wish). It also has an effective speech compressor that is of
particularly high value to users of vintage ham equipment. Comes with a
copy of the manual.
$85 shipped in CONUS.
