Keyer, ECONO Keyer II with memory

The same as MFJ-407D except weight and tone controls are adjusted internally and doesn't have a tune switch

Use 9 volt battery or mains adaptor (not supplied)

  •  Size : 4 x 1 3/4 x 3 1/4 inches.
  • A 9-volt battery (not included) may be installed. Remove the cover by removing the two screws (one on each side) that secure it.. A battery holder, located inside the enclosure, is provided for installing a 9-volt battery.
  • A 12 Vdc power supply may also be used to power the MFJ-401E. A 2.1mm coaxial plug with a positive center and a negative sleeve should be used to power this unit. The battery is automatically disconnected when external power is used.
  • 3. A squeeze or single lever key can be used. Squeeze key allows Iambic operation. A 1/4-inch stereo phono plug and a two-conductor shielded cable should be used. If separate shielded cables are used, the two shields should be tied together and connected to ground. The dot wire should be connected to the tip of the plug and the dash wire to the ring. The MFJ-401E becomes a manual keyer when a straight key is used. The unit will safely key your transmitter and eliminate the shock hazard of high voltage being present on the straight key.
  • Note: To use a straight key, first switch the keyer to the Semi-Auto mode
    (button in). Again a 1/4-inch stereo phono plug should be used
    because a mono plug will not work on a straight key in Semi-Auto
    mode. Connect one wire to the ring of the plug and another wire to
    ground. The tip of the plug should not used.
  • Output keying circuit allows keying of grid-block and solid state
    transmitters. Remember this is internally jumper selected (refer to page 2).
    The keying output connection is made with a RCA phono plug.
    Note: Consult the transmitter's instruction manual to determine which
    output to use. When in doubt, try both jumper positions. The
    transmitter will key continuously when the jumpers are connected to
    the wrong positions.
