@@anissoulhaci2653 - do you, by any chance, have the schematic of the front end broadband RF amplifier, please. The .zip file doesn't have the schematic.
Hopefully one day we will see a 30 MHz to 3 GHz VHF-UHF receiver like this in the future. I will try this out soon. Now I see why I got started in Arduino in 2019, because of breadboard projects like this.
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?
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?
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 ?
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?
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.
@@8_Bit_Cloud i and q are both similar signals but they are phased in 90 degree (cos and sin) they both carry the final audio of the whole received bandwidth of the received radio signals , thats why you can view a lot of station on spectrum
can I get the all details about this project such as where I can buy this sdr parts?.....and any tutorial for Undergraduate projects...Excellent project BTW🤩🤩
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
@@anissoulhaci2653 thanks man! I have BF200, MPSH10 with me. Will build it on a breadboard first. Thanks again! It'll be hard to find 4mm dia ferrite rod though!
@@awaismushtaq5719 breadboard build too much capacitive noises especially dealing with vhf uhf because every gap on breadboard represent a small picofarades capacitor so i suggest you doing it on copper pcb
Hi nice project. well done Where, if possible can I download the information. I found a link but after download it is reporting that the RAR file is unknown or damaged format regard and keep up the good work
@@dare-er7sw cd4066 i think you can't go above 12 or 14 MHz , (HC or LC ) logics are fairly limited in terms of switching , but the HC or HCT are more faster and can reach above 100MHz
You wrong. is NOT "to many cable"... TOO many wire jumpers... I strongly suggest resigning C.I.A. and going back to primary school... Greetings from Argentina! (South America. Far away from Mexico).
It shows, to get good results, it doesn’t always have to be complex
Excellent work mate! Cool project! Simple and elegant! I have the Si5351 module and other chips
Excellent work, sir. Very good! I'm gonna try this
best i ever seen in rhe field of diy on breadboard !
verry excellent done!
mY congratulations(clapping hands)
thx!!!!
Thank you so much man i appreciate that
well done young man, keep up the good work
Thanks 73s
You are the best! Im going to try it

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)
That is awesome!!!
Thx for this tutorial dude! :D
You're welcome dude
Pretty cool
Thanks!

@@gorillaau also, you need a LNA preamp to amplify the signals.
@@parthd714 Yeah. That's true. I forgot about the Low Noise Amplifier preamp.
Thanks for the files I just start construction
Enjoy
Can you help me for its construction.. Please
good video! one question, about the I and Q signals, they go separate on each channel? left and right? how do this work?
Yes exactly! Thats why you need stereo soundcard input not mono
@@anissoulhaci2653 If you use only one it will work? I to directly to aux and ground will this work?
@@8_Bit_Cloud its works but it will have mirrored spectrum
@@anissoulhaci2653 I'm confused Like How do you connect this Q/I to aux and feed to aux input of PC? Bit Enlight me about this Q and I signals
@@8_Bit_Cloud i and q are both similar signals but they are phased in 90 degree (cos and sin) they both carry the final audio of the whole received bandwidth of the received radio signals , thats why you can view a lot of station on spectrum
awesome. I would like to try that. thanks. K1QS.

Спасибо
пожалуйста
How are I/Q outputs connected to the sound card? Why do you need both if there is no DSP involved?
I/Q outputs enter the soundcard because they are baseband or the actual audio output
KEEP GOING
Thanks brothaa
