10 MHz WWV Receiver Experiments


10 MHz WWV Receiver Experiments

For nearly a year, I have been trying to develop a tuned radio frequency TRF 10 MHz, WWV, AM receiver. My initial RF stages were common emitter or common source stages with tuned input and output

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

Di fondamentale importanza e' l'impiego di toroidi di materiale corretto, adatto alle gamme di frequenza interessate

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

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
