by the MixW team, the
RigExpert Tiny is a revolutionary new sound card to transceiver
interface. Combining complete functionality, simplicity of use,
excellent design and low price, the RigExpert Tiny is perfect for all
digital modes and CW/Phone. Models built for different
transceivers like the Yaesu, Icom, Kenwood and Ten-Tec are now
interface provides a CAT port (transceiver frequency and mode control
using a computer), a second serial port (PTT push-to-talk and/or CW
output), as well as the soundcard-to-transceiver audio interface.
The transceiver and computer connections are made using pre-wired
cables for your specific rig. The computer connection uses the
USB port, freeing up your serial (COM) ports for other needs. A
separate power supply for the RigExpert Tiny interface is not needed as
it is powered by your USB port. Five LED's on the top panel
display the device status, helping set up the computer software and
monitor functions during on-air operation.
The RigExpert Tiny
interface is fully compatible with all amateur radio
software running under Windows 98/ME/2000/XP/2003/Vista/7.
supported are Linux and MAC OS 8/9/X operating systems.
Software programs like DigiPan, MixW, MMTTY, MMSSTV, EchoLink, Ham
Radio Deluxe, DXBase, N1MM, K1EA CT, ACLog and CQ-Log just to name a few are fully
A block diagram of
RigExpert Tiny is shown to the left. The "heart" of this unique
interface is a dual-port USB converter chip. In this diagram,
both ports are set up to operate in serial mode. One of the ports
transmits and receives the CAT system data, while the other port drives
the PTT and CW outputs.
After the RigExpert Tiny
is connected to
the computer and the drivers are installed, two serial ports of your
choosing (i.e. COM8 and COM9) are available for the software.
serial ports within the USB cable are just one of the many unique
features of the RigExpert Tiny interface. The simultaneous use of
two separate programs is an important asset to you as seen in the
illustration to the right. One port operates the digital mode (driving
the PTT and CW outputs). The other port controls your QSO logging
software working with the CAT system. The diagram on the right

dividers are used in the audio signal I/O
paths from the computer to transceiver providing fast and error free
audio transfer. All input and output lines are fed through R/C
filters to attain the highest interference and RFI suppression
The computer to
transceiver cable length is 2.5m (8'2"). Needless
to say, all cables are fully shielded.
