Two versions of the receive converter are presented. The first, which uses an active NE602 mixer, is easier to build, but is more susceptible to overload by very strong signals. Two additional 2N2222s and a 2N2907 device are employed for local oscillator and r.f. Multiple on-air contacts have confirmed the unit functions quite well, and is an inexpensive way to provide 17 meter coverage for those who don t have this capability . This kit is best suited for intermediate homebrewers who are comfortable with building projects Manhattan-style .
