Have you got two radios, but only one keyer, one headphone set, one paddle and other accessories? MFJ will unclutter your operating position and save you money -- you only need one microphone, keyer, soundcard interface, iambic paddle,
etc.

MFJ-643 lets you operate two radios with the following accessories: Desktop and headset Microphones, keyers/keys/paddles, soundcard interfaces, modems, etc. The MFJ-643 is designed for easy use. Just set the internal jumpers for the MFJ-
393 Professional Boom-Mic Headphones, Heil series headphones, a computer boom-Mic or computer boom-mic Headset. You get instant LED visual indication of the transmit audio path so you know which radio your audio is being sent to.

On receive, you can instantly choose between Mix, Radio 1, Stereo or Radio 2 depending on how you want the audio presented to your headphones. The input source connector is a 3.5mm stereo jack. Your input source can be a dynamic or
electret mic (low or high impedance), stereo or monaural receiver audio, sound card or modem, or key or keyer.

You have a choice of PTT functions: Use your microphone's PTT switch, a foot or hand switch or the convenient PTT switch located on the front of the MFJ-643. There are also additional inputs, dual outputs for your keyer, and two lines to
switch an antenna between your radios, key an amplifier, or anything else you want to use them for. Use 12 VDC or 110 VAC with optional MFJ-1312D power supply. Compact 7-1/4"W x 2-3/4"H x 5-1/2"D.
