High performance regenerative shortwave receiver - covering 160m to 16m band - Charles Kitchin, N1TEV

This regenerative shortwave receiver is highly sensitive and selective and it covers the following frequencies: 1.6MHz-4MHz, 3.4MHz-8.5MHz and 6.8MHz-18MHz.
The RF stage amplifier and low impedance input/high impedance output is accomplished with 2N2907 bipolar transistor. The 1Kohm R1a potentiometer is a very effective RF input atenuator.
The audio amplifier stage uses AD745 FET operational amplifier.
The receiver draws less then 12mA using two 9V battery.
