Even beginners can easily build these high-performance direct conversion receivers for the HF bands. youll be pleasantly surprised with their excellent sensitivity that rivals receivers costing many times more. Youll marvel at the clear reception of DX signals from all around the world when you copy CW, SSB, and even AM signals. You can build it to cover the entire band or tune it to cover just a portion of it for smooth band spread tuning.
The kit is ideal for on-the-go or at-home QRP operation with your homebrewed QRP transmitter from the Vectronics 40 meter QRP CW Transmitter Kit.
High performance is achieved with a NE602/612 mixer-oscillator chip connected differentially to a high gain LM386 audio amplifier. The oscillator-mixer is voltage regulated by a 78LO5 for beset stability. The antenna input has a high-Q parallel tuned circuit with a front panel RF gain control to minimize interference and prevent overloading from strong signals. it has smooth varicap tuning with a shielded VFO coil for maximum stability. you can configure the tuning to cover the entire band or to cover just a portion of the band for more bandspread tuning. Delivers plenty of volume for head phone operation and will even drive a small speaker. uses 9-volt battery (not included). The kit measures 1¾ x 4¾ x 5 inches.
