GR 40 Reciever

GR-40 Rx made for Demo purpose by RnD Team

GR 40 is simple single conversion Super Heterodyne Receiver. A 4-section XTAL ladder filter at 12MHz IF is used to select the band width. The receiver consists for two single side PCB assemblies namely GR 40 Rx. Main Board and VFO.

To cover 40meter band i.e. 7MHz to 7.2MHz, the VFO covers 5 MHz to 4.8 MHz. The VFO is buffered by a two-stage amp with feedback.
