Kiwi CW 40mt
The model described here works on the 40-meter band
LC Meter based on PIC16F628A
This is one of the most accurate and simplest LC inductance / capacitance Meters that one can find, yet one that you can easily build yourself
LC Meter kit has sold out
The LC Meter is a Morse code inductance - capacitance meter kit
Multiband Transmitting BPF Project
After installing a couple of wire antennas in the trees we discovered that when one of us was transmitting the other couldn't receive anything but interference. I later learned that simultaneous operation of two radio transmitters in close proximity on separate bands will overload and desensitize the radio's receivers. A bandpass filter for each radio can be used to reduce this problem but the filter must be able to withstand the transmitter's power

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