MFJ-1270X

The TNC-X is a low-cost, low power TNC currently deployed in thousands of locations all over the world. Just connect your FM radio and your computer and the world of digital packet radio is yours to enjoy.

TNC-X is a KISS mode TNC. It works with every packet radio software program that supports KISS mode. KISS mode makes it extremely simple to use. There are no complicated menus of parameters to adjust.

TNC-X is a genuine USB TNC, not a TNC with an outboard serial to USB converter added to it. As a result, when you plug it into a USB port on your computer, it derives its power from the USB port. It works with all major computer operating systems including Windows, Mac OS X (as well as Mac OS 8 and 9), and Linux.

It beats the competition in decoding packets from poorly adjusted transmitters. You get a built-in active audio filter in front of the TNC's modem to clean up analog signals before they are digitized.

It is natural for emergency communications and is being used in this application across the country and around the world.

TNC-X is perfect for APRS. It is fully supported by virtually every APRS mapping program in use today.

TNC-X contains an expansion header that allows you to add daughter boards to provide entirely new capabilities. With TNC-X, you only buy the capabilities you need. You don't to pay for features that you will never use.
