Sign up for the digital revolution and explore a whole new world of amateur radio excitement using MFJ's universal USB radio interface! The new MFJ-1204 USB Radio Interface is exceptionally easy to setup and use. However, simplicity doesn't mean compromised performance.

Here are just a few of the MFJ-1204's advanced features:

• Full USB connectivity
• Powered by USB port
• Dedicated on-board sound card
• Quick plug-and-play connectivity
• Incredibly easy to adjust and operate
• Works with all digital modes
• Dozens of free downloadable programs
• Innovative circuitry eliminates delay control
• Complete line of interface cables
• Low cost, small size, light weight
• Perfect for base station, portable, or "go-kit" applications

Initial no-solder jumpers take only a second to install, and once in place, they're locked in until you decide to change radios. To hook up, simply connect the MFJ-1204 to any free USB port on your computer and plug the appropriate interface cable into the back of your radio. That's it! No need to disconnect the microphone or fumble around with multiple patch cords to get started.

Convenient front-panel controls set Receive and Transmit levels and there's no front-panel "Delay" to adjust because the MFJ-1204 controls your radio's PTT line using a unique internal detector circuit. Transmit and receive using traditional modes such as CW, RTTY, SSTV, AMTOR, PSK31, and EchoLink or explore newer modes like MT-63, WINMOR, WSPR, and WSJT-X. In fact, new experimental modes are emerging all the time. If your radio can pass the signal and computer can run the mode's online software, MFJ-1204 sound card and computer will handle the rest! Just select a cable configured for your radio, plug it in, and go. The signal path between the radio and computer is completely isolated against ground loops and common-mode noise.
