The latest low-power embedded microcontroller technology is used to give you the features you want, with the ease of operation you need. Advanced operating modes such as message pause, auto-repeat (beacon), QRSS and HSCW are a snap -- and with future firmware upgrades, even more features are just a quick (and free) upgrade away!
Of course the MasterKeyer can be used as a top-quality, fully featured stand-alone keyer, with no computer or keyboard required. All the operating features you expect, and some you may not, are built in and ready to use. The built-in USB capability can add a whole new dimension to your operating! The USB host connector -- the only one on any keyer, anywhere -- can be used to load new updates directly from a USB FLASH drive, without using a computer. You can also save all operating parameters and memory contents to a FLASH drive, so you don't risk accidentally losing your settings. Edit the simple text file if you wish to suit your exact needs. The ability to save and load the entire configuration makes this keyer perfect for clubs and contest stations! If multiple operators use the same keyer, just plug in a FLASH drive and load ALL your own settings and memory messages in seconds. Of course, the same feature can be used to "clone" your settings from one keyer to another if you need stations set up the exact same way.
This keyer is presently offered only in fully assembled and tested form. The enclosure is top quality, rugged aluminum with a textured black powder coat finish. Silkscreened legends mark all operating controls and connections. All documentation is on a CD-ROM, as well as software drivers for Windows PCs (drivers are already built into Mac and Linux systems). A power cable is included to connect to your power source.
