Keyers & Keys

MFJ 482 Grandmaster Memory Keyer - Sold!

MFJ 482 Grandmaster Memory Keyer -- Excellent Condition -- Code speed is variable from 8 to 50 WPM. The speed does not “bunch up” over a small part of the adjustment range; it is even throughout the range of adjustment. The weight control, when set for normal establishes a 1:3:1 dit/dah/space ratio. Clockwise rotation of the control initiates progressively more weighting. There is a built-in sidetone oscillator and monitor speaker. The sidetone pitch can be adjusted from the front panel of the unit. Similarly, there is a sidetone volume control located on the front panel. The memory features of the keyer permit the operator to place 25 characters into any of the four memory positions, A, B, C, and D. Memories can be combined to provide up to three 50-character messages, or all four memories can be bridged to accommodate a 100 character message. By utilizing the memory selector switch it is possible to choose between individual 25-character messages. Momentary push-button switches are located on the keyer front panel to send each of the four messages separately. A “repeat” mode allows the message to be repeated automatically. The time delay between the repeats of the message is infinitely variable between 0 and 2 minutes. Automatic repeating will continue until the paddle is tapped or until the reset button is pushed. The reset switch is used to stop a message instantly. Size is 2 X 8 X 6 inches. Power is dual: either an external 12-15 volt dc or internal battery. Keys both tube and solid state rigs. Tone and weight are infinitely adjustable. Price: $45 shipped (in the lower 48 states).
