A Beverage Antenna
For a Beverage to Work reasonably well you need at least 1 wavelength of wire. On 160 meters that's 490 feet of wire in as straight a line as possible

A Control Box for the K9AY Loop Antenna
The control box allows to switch the direction and to change the termination resistor, so I decided to scan and reconstruct the drawing and PCB design for others who may need it
Antenna Biconica
The so-called biconical antennas are a typical example of antennas for broadband measurements
Trasformatori e Chokes per ricezione in 160 metri
Di fondamentale importanza e' l'impiego di toroidi di materiale corretto, adatto alle gamme di frequenza interessate
Power supply loop wellbrook ala1530ln
Sostituzione alimentatore per antenna-wellbrook-ala-1530ln su schema LM317 con trasformatore
Rx antennas 4Square Rx Vertical Array
My frequency design of 1.825 MHz a 90 degrees line would be 33,70 metersinstead of the previously calculated 33,27 m

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
