Specialty Parts Kit 

for the

Small Wonder Labs' PSK-20 Transceiver

This kit is sold out and is no longer available.

The NJ-QRP Club is pleased to be able to assist homebrewers all over the world by providing the specialty parts for the "PSK-20" Transceiver from Small Wonder Labs. This inexpensive project is a single-board 20m transceiver capable of PSK31 operation when used in conjunction with a PSK31 software program (like DigiPan) on your computer.  The "Panoramic Transceiving System for PSK31" was the subject of an award-winning article in QST for June 2000 and was featured on the front cover of that issue.

1) If you have already ordered the PSK-20 Kit from Small Wonder Labs, you do NOT need these specialty parts from the NJ-QRP Club.  The parts are already included in the PSK-20 Kit.

2) These specialty parts are being provided only as a "set".  We are not able to provide them individually.

3) See a photo of the PSK-20 transceiver board.

4) You can download the QST article, A Panoramic Transceiving System for PSK31 from the ARRL webpage featuring PSK31 information.
