Welcome to the TAK-40 Wiki!

About This Site

This wiki is to help gather all the available information about the TAK-40 in one place.

The TAK-40 was entered in the ARRL HomeBrew Challenge, which was announced in August 2006 QST with entries due Aug 2007. The challenge was to design a 40 meter CW and Voice transceiver that could be reproduced for under $50.

While the TAK-40 met all the goals of the contest, the radio's creator, along with many of the builders have made improvements, such as printed circuit boards, more stable VFO, and a 10 watt PA board. All of these options push the build price up depending on which options are added and how creative one is in sourcing parts and enclosures.
