The “Small Wonder - 30+”
30 Meter Superhet Transceiver Kit
Thanks! For purchasing one of the Small Wonder Labs “SW-30+” transceiver kits. This kit is an updated version
of the classic ‘40-40’ transceiver board which originally appeared in the November 1994 issue of QST.
Please take a few moments to look over the section entitled “First Things First”. This is background information
in case you’re fairly new to homebrewing or kit-building.
Please – Be sure to read through the “Building Instructions” portion of this manual before you fire that
soldering iron up! That section contains useful information which is important to your success with this kit.
