KEY Jack
This 1/4-inch, 3-contact jack accepts a CW key or keyer
paddles (for the built-in electronic keyer), or output
from an external electronic keyer. Pinout is shown on
page 15. Key up voltage is +3.3 V DC, and key down
current is 0.3 mA. This jack may be configured for
keyer, “Bug”, “straight key”, or computer keying in-
terface operation via Menu item “
037 A1A F-TYPE037 A1A F-TYPE
037 A1A F-TYPE037 A1A F-TYPE
037 A1A F-TYPE”
(see page 111). There is another jack with the same
name on the rear panel, and it may be configured inde-
pendently for Internal Keyer or pseudo-straight-key
operation.
NOTE:
You cannot use a 2-contact plug in this jack (to do so
produces a constant “key down” condition).
