LZ1AQ Loop amplifier boards

Everett N4CY

I have Two LZ1AQ Loop Amp boards built and tested using SMD 2SC5551 transistors. These new boards have more gain, Lower Noise and are more sensitivity on Low Wave than the l original design using 2N2222.
The gain is over 30dB from 100kHz to 20MHz then drops to around 28dB at 30MHz. The input impedance is less than 3 ohms from 100kHz to 15MHz.
If there is any interest in buying one please contact me off list at everettsharp (at) aol com.
