“This is my remake of Mirko Pavleski’s Universal VFO 10 KHz-160 MHz with Retro Analog Scale project. The Si5351 Clock Generator has three independent outputs. Each one can have a different frequency. Part of this redesign is to make …
“In this project, we will upgrade a traditional shortwave superheterodyne receiver with an Arduino base tuner. This tuner is capable of receiving shortwave broadcasts on 41m band and above. This modularized receiver consists of a transistor base mixer, I.F …
“For use in DIY homebrew radio equipment such superheterodyne receivers, SDR, HAM QRP transceivers or RF generator. This is a project of a VFO (variable frequency oscillator) for use in DIY homebrew radio equipement such as Superheterodyne Receivers, DCR, SDR …
“Clock generator I recently build a pulse generator and it does its job well. It produces pulses of variable length and at several frequencies. But the number of frequencies it can produce is limited and for many jobs the length …
“Why would you want to look at those tiny led displays or those small LCD’s if you can do it big? This is a step by step description on how to build your own Giant sized Spectrum analyzer. Using …
“Sensitive retro look radio capable of receiving signals from middle wave and short wave band. This radio receiver is capable of receiving all MW and SW bandwidth, and can also operate as an SDR receiver, so with the help of …
“This is a revised version of my FV-1 based SDR. I replaced the CS2100 clk generator with the Si5351 clk generator. The Si5351 has some advantages over the CS2100, namely you can generate quadrature clks directly. This simplifies the …
