The ATL-3 Loop Antenna
This antenna is the result of long term development and user feedback. Read more...2 Transistor Transmitter
A compact 2 transistor transmitter for use at VHF frequencies. Read more...Simple Field Strength Meter
This Field Strength Meter is simple and also quite sensitive. It uses an ordinary digital voltmeter to measure RF signal strength up to a few hundred MHz. Read more...Field Strength Meter
This is a wide band signal strength meter circuit which responds to small changes in RF energy, designed to be used for the VHF spectrum and will respond to AM or FM modulation or just a plain carrier wave. Read more...
