PERATION
This section describes the operating procedure using a manual “straight key.” This section also pertains to opera-
tion using the output from an external electronic keyer, or from a CW keying interface utilized with a personal
computer (using contest software, etc.).
OPERATION

Insert your key’s ¼” three-conductor (“stereo”) plug
into the
KEY
jack on the rear panel of the trans-
ceiver. Remember that the Tip of this plug is the
“hot” key lead, while the main shaft is Ground; the
Ring is not used.

To transmit, simply press the straight key (or start
sending on your external keyer/computer). The
