Page 28 MFJ-464 Instruction Manual CW Keyer/Reader Decrement – decrements the serial number by one, effectively canceling the automatic increment applied when last played from a message. The decrement function accommodates re-sending the last serial number, as might be needed when a repeat of a contest exchange is requested, or canceling the exchange with a station that proved to be a “dupe”.
Page 29 MFJ-464 Instruction Manual CW Keyer/Reader Keying compensation – sets the keying compensation to ## millisecond, where ## represents two digits in the range of 00 to 25. Some radios have a key delay of 5 ms or more. By entering K05, the keyer will add 5 ms to the dots and dashes and subtract 5 ms from the intra-character spaces.
Page 30 (#=H) mode. With the automatic option, the keyer functions as an iambic keyer for use with a dual-lever paddle. As an iambic keyer, the MFJ-464 has dot and dash memories for "squeeze keying" and functions just like other iambic keyers, both standalone keyers and those built into radios.
Page 31 Tone – sets the sidetone frequency to approximately ##0 Hz, where ## represents two digits in the range of 30 to 99. The MFJ-464 features smooth, clean audio, with sine wave output, instead of the harsh square wave audio used by many other keyers.
