MFJ-401D Econo Keyer II is a microprocessor controlled keyer that provides
iambic key operation or straight manual key and dot-and-dash memory to make sending perfect code easier. It has tunable code speed, code weight, and sidetone frequency; it
supports both direct and grid-block keying outputs. You also get to choose between Iambic Type "A" and Type "B" keying or auto or semi auto modes or straight key manual code operation mode. The MFJ-401D uses a 9 volt battery or 12 VDC. Operation from 110 VAC is possible with a 12 volt DC wall wart power supply. New battery installed, manual included. Put that old AM-CW boat anchor on the air with your iambic, paddle or straight key. $45.00 Shipped, Roger, K8CIX , email:
