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
175

Noise suppression with X-phase II This device similar devices are known as QRM eliminators or noise killers, makes it possible
The K9AY loop antenna for 160 and 80m bands You don't have the space to put up a 4 beverage antenna's, an ewe or a 4-square and want 'good ears' on 160 and 80m? no problems try a k9ay loop antenna
Spiderbeam 10-15-20m E' una Yagi tribanda full-size leggera, fatta di tubi in vetroresina e filo
