    <H2>Small Wonder Labs is proud to offer the PSK-20 transceiver kit for the exciting PSK31 mode.</H2>

    This design is a derivative of the SSB transceiver appearing in the April 1997 issue of QST. It's been streamlined for ease of construction and alignment, and many of the higher installation-skill conponents have been designed out.




    Intended as an entry-level platform for PSK31 use, it covers the 14.0695-14.073 segment of 20M where most of the PSK31 activity is found. The design retains the same relatively high dynamic range of the QST SSB rig as well as good transmit IMD characteristics.



    The rig is crystal-controlled and was designed to work with the popular (and free!) DigiPan software. Output power is 3W PEP. The crystal control provides excellent stability and its simplicity keeps the cost low.

    Kit assembly is straightforward- there are only four toroids to wind. The number of adjustments is kept to the minimum consistent with good performance, and no special test equipment is needed to perform the alignment. There’s no harness wiring- all interface connectors mount on the rear of the circuit board. The board kit includes a 26-page manual with color figures. Step-by-step assembly instructions are included.



    A 40M version, the PSK-40, will be available soon.
