[Dx4win] CW Keyboard question

Sun, 5 May 2002 07:23:11 -0500

Mike,

This is true for most modern radios - aside from the 1/8" size of the plug
although I think the FT-100 and IC706 uses a 1/8" stereo as well.

All Yaesu's, Icom's, Kenwood's use a stereo connector now so that the jack
can be used for both a paddle input to the built-in keyer or for a straight
key.  A notable exception is the Kenwood 950SDX that has an unusual
provision for straight key (or computer interface) which is paired with the
remote keypad jack which is also 1/8" stereo.  This allows you to use the
built-in keyer along with an external device.

73,
Bob N5NJ
