MFJ-422D
Keyer & Paddle

Discontinued!

The MFJ-422D deluxe keyer fits right on top of the supplied BY-1 Bencher iambic paddle for a very compact configuration. It gives you volume and speed controls (8-50 WPM) on the side panel. The rear panel has adjustments for tone and weight. You also get built-in dot-dash memories, speaker, sidetone and push button selection of semi-automatic/tune or automatic modes. Ultra-reliable solid state keying: grid-block, cathode and solid state transmitter (-300V, 10 mA max, +300V, 100 mA max.).

If you already have the paddle, you can buy just the keyer as MFJ-422DX.

Requires a 9 volt battery (not supplied), 12 VDC or will operate from the optional MFJ-1312D AC adapter.
