Making the LFA Loop
To build an LFA but the prospect of making a loop is a little challenging
Multi-loop Rectangles and Compact Arrays
Is composed of four rectangles. But, before studying this antenna and its use as an array component
Octoloop antenna is a shielded multiturn loop
The octoloop is easy to make You need some 3/4 in hard copper pipe, eight 45 deg elbows, and two male threaded adapters
Portable Magnetic Loop Antenna 20, 30
Described here is a simple multi-band magnetic loop antenna designed for 20, 30 and 40 metres
Programma di calcolo del condensatore
The diagram shows a capacitor with three 4-square-inch plates, separated by 0.25 inches of air. Its calculated capacitance is 7.18 picofarads

PIC-Keyer This project describes the construction of a real "QRP" keyer with a small microcontroller PIC 16F84, with slightly modified hardware also PIC16F62
RF Inductance Calculator Mean diameter of the air core coil, measured from conductor centre to conductor centre include the wire insulation thickness, if any
Voice Recorder Gestito dall'integrato in questione ed offre la possibilità di registrare più messaggi per una durata massima di un minuto con buona fedeltà di riproduzione
