40 Meter Rotatable Dipole
It is an excellent all-around 40 meter antenna for those who don't have room for or can't afford a yagi
44/28 MHz Transverter
Sono stati sviluppati i relativi circuiti stampati utilizzando dove è possibile utilizzare componentistica di tipo SMD
6AQ5 CW Transmitter
How's this for no-frills hamming? This cute little 40 meter CW transmitter is nothing more than a 6AQ5 oscillator coupled to the antenna
6m Yagi-Uda Antenna Computer Simulation Design
I first saw such kinds of articles on Japanese CQ magazine or Japanese Ham journal No.65 in late 80's. I recognized that there was a trial of let's do the optimization of the antenna by using a computer
A 2 MHz Transverter Project
supply voltage 12 vdc +/-X @X ma, IF of 28 MHz for Tx and Rx

Antenna splitter per VHF-UHF per quattro ricevitori Chi dispone di una sola antenna e vuole collegarvi più di un ricevitore necessità di uno splitter
Amateur radio kits by Kanga US
50MHz to 28MHz RX Converter The concept of the rx converter is quite simple and nothing really new. the local oscillator is a standard colpitts crystal oscillator producing the 22mhz lo signal
