A Portable Low Frequency Antenna Analyzer
For those of us who like to play with antennas on the ham bands, one of the handiest tools to have around the shack is an "antenna analyzer

Visual CW Tuning Indicator
Many transceivers set the CW transmit off-set equal to the set's sidetone frequency. But it was left to the operator how to match incoming signals to the sidetone for one-frequency QSOs -- an awkward and time-consuming procedure
Wide-Range Antenna Arrays For the Roanoke Doppler
Doppler units are the "weapon of choice" among mobile T-hunters in many parts of the country. They indicate the direction of incoming VHF signals on a circular ring of light-emitting diodes or a digital display
A Complete 13.8 Volt, 20 Amp PSU
Power supply interested in a 13.8 volt, 20 amp P.S.U. which is suitable for powering the average solid state HF rig or 100 watt VHF/UHF
Build a Saltwater Dummy Load
Certainly any reasonably sized load will work up to 30 MHz, up to 50MHz is possible if care is taken in it's construction

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