The Little Roo is a nice 40m receiver than can be built for either 40m CW Sub Band or the majority of the 40m SSB sub band. supplied with all parts including the 'Mint Tin' style case, The receiver uses the NE602 and LM386 comb that is well know in such as the Sudden Receiver and others, the VFO is controlled by a Ceramic resonator and gives approx a 100KHz swing of which ever sub band (SSB/CW) you choose. Will power headphones or a speaker. When finished the receiver is powered by a standard PP3 9V battery that also fits into the Mint Tin case. Great fun to build but not the best choice for a First Project due to the component density.
Good choice for an intermediate level build-a-thon!
