The microHAM DXP™ is a lightweight, portable transceiver-to-computer USB interface with high dynamic range and low noise 24-bit audio ADC and DAC to facilitate high quality Digital operation (FT8, RTTY, JTxx, PSK31, etc.) and FSK. CW operation is supported by the time-proven WinKey CW keyer developed by K1EL, now in version WKv3.1 with FSK support.

DXP™ is the first microHAM interface entirely utilizing Standard USB Class Devices for its USB operation. This means, that drivers are already incorporated in all current major computer operating systems, no driver installation is necessary. DXP does not need our USB Device Router for operation.

The microHAM DXP™ USB interface is fully powered from a standard USB port while maintaining full galvanic isolation between computer and transceiver. The relay-free construction of DXP provides quiet operation based on an optoMOS part replacing the traditional output relay. CAT interface is jumper-free set up from the menu. The DB15F system connector is fully compatible with previous microHAM interfaces: USB II, USB III, DK, and DK II and uses the same DB15 cables.
