Great if you could comment about the antenna used and post the SDR circuit. Thank you for the enlightening video.

[@odissey2]

Good project. It is a Tayloe mixer in a simplest form - no input transformer, magnetics, etc. The C1 and C2 can be increased to 100n to make LPF cutoff 3-5kHz for better S/N. The 74HC74D can be omitted, further simplifier design, - here it is used to generate a quadrature pair I and Q, which Si5351 can produce directly. It is very impressive that it worked on a breadboard. What actual broadcasting frequency was captured in the video?

[@anissoulhaci2653]

Hello man thank you for your great tiny explanation . Well the frequency i think its about 7200Khz from radio am senegal (if im not wrong)

Nice video but why is you RF preamp in the first diagram pointing backwards ?

[@stevejustin]

where is the doc to do this project ?

[@bourasabdennour8369]

Brilliant brother ...according to your scheme that you illustrated in the begining of the video, you built a zero IF or direct sampling demodulator. Theorically you must have a perfect matching between the I path components (mixer, low pass filter ) with the Q path components or you will get what so called "IQ imbalance" and of course ADC sample rate has to verify Nyquist-shanon condition. Seeing that you used such hardware , am really wondering about how it is performing ?

[@slavauchitel8014]

How are I/Q outputs connected to the sound card? Why do you need both if there is no DSP involved?

[@anissoulhaci2653]

I/Q outputs enter the soundcard because they are baseband or the actual audio output

[@eknuds]

I was wondering what I would have to change if I wanted to receive in the 2m band? I think using the Si5351 to generate the quadrature sounds like a good idea too. Do you have any recommendations for the type of capacitors to use?

[@williamrmeara2162]

Cool project. It shows how older more traditional analog technology (RF amplifier, mixers, LP filters) fits in nicely with the software DSP. But today this is a bit of an old-fashioned fairy tale, right? Today we just an ADC at the antenna and send the digital stream into the computer for processing, right?

[@gorillaau]

Yes, thpugh it depends on the speed of the computer. You are not going to be able to do much in the microwave bands for example. Instead you'd problably need to downsample the wanted receive frequency and input that into your computer/raspberry Pi/favourite platform. Some of these modules makes sense to still have it in hardware. A LP is so simple, that it's piece of mind that you are not transmitting harmonics across large amount of the spectrum.

[@parthd714]

@@gorillaau also, you need a LNA preamp to amplify the signals.

[@gorillaau]

@@parthd714 Yeah. That's true. I forgot about the Low Noise Amplifier preamp.

How can I increase the frequency range, i need 20-1800 MHz range

[@anissoulhaci2653]

1800mhz first local oscillator cannot reach 1800Mhz second the flipflops cannot switch above 40Mhz same with analog switches, so you need fancy RF components that allows you to reach your desired frequency
