Building The Small Wonder Labs SW40+

Parts of the inside front panel were ground down with a Dremel to allow the LCD to mount.

Part of the original mounting hole for the Messenger's volume control had to be cut away for the LCD to fit.

The N3ZI kit is a very nice and simple way to add digital frequency display to a qrp rig. Doug’s Universal kit is available without a LCD, allowing you to use your own. The price is only about $20. By the time I purchased an LCD display from eBay, the total cost to add a digital frequency display was under $30! If you order the display from China, the total price will be under $25. The kit can be seen at Doug’s web site here:
