QRP 40m Kit by KF6KXG

MikeL2I recently ordered an EFE40 SSB QRP radio from Ebay. A ham from Turkey has a small Ebay business selling these. He lists about one or two per week. Search Ebay under “QRP“. The radio arrives as two assembled boards and a volume control. One board is the digital dial and the other the RF board. The buyer has to supply a case, knobs, some hookup wire, switches, a speaker, and connectors. In the first picture, you see it operating in breadboard form on my bench. Below that is the finished radio mounted in the case. I used a plastic case found on AliExpress and an aluminum faceplate around the dial area. The hardest part is obviously making the rectangular opening for the LCD screen. I drilled a hole and used a sabre saw to rough it out. I then attached a metal straight edge along each side of the opening and used a Dremel tool to grind it to the final size and shape. I found the aluminum was easier to accurately shape than the plastic. The receiver is amazingly sensitive and the 5 watts output has received good reports.
