Homebrew C-L-C QRP Antenna Tuner
His is a C-L-C type tuner with a reflected power indicator. Tuning is done for minimum reflected power. Forward power indicator is omitted because I know the output power of my transceiver anyway

L-Match ATU
After much thought I decided to build a L-Match circuit but with flexibility to match a wide variety of situations.

Modifications to the Single Coil Z Match for 1.8 MHz
The original Z Match circuit modified to include 1.8 MHz. The addition of three fixed capacitors and a 4 position switch gives the whole load resistance range at 1.8MHz

Solar Powered Antenna Tuner
Once the tuner determines the frequency of the RF signal being transmitted, it stores the tuner settings in its non-volatile memory for use in future tuning events


PIC-Keyer

PIC-Keyer This project describes the construction of a real "QRP" keyer with a small microcontroller PIC 16F84, with slightly modified hardware also PIC16F62
