SDR School Part One The Basics

If you feel a little left behind with all this new-fangled SDR stuff, this video is for you! SDR School is presented in a non-technical fashion. Part one covers SDR basics, Part two will cover SDR hardware, and part three, the software. I hope you find it helpful. Dave W8KFJ

SDR's are such an incredible instrument. Ive added an SDR to my trusty superhet transceiver, they make an incredible combination my RSPDX-R2 tapped into the RX port on my rig lets me have an ancillary receiver that i can see the entire band that im working and have a scouting receiver to find or monitor a net that im participating in. What ive found is sometimes the SDR hears something the superhet cannot but also sometimes the superhet hears a signal better than the SDR. Together they compliment each other. I really enjoy Daves teaching on these excellent instruments, i could listen to him all day long. 73 de N3TGY

Oh my God...I got my amateur advance in 1967. I am 78 years old. Built repeaters on UHF and VHF with auto patch. You could not buy one you built them from surplus parts and tubes rule the world of amateur radio. I like your class of instruction, but feel so out of touch, but think I am going to get a SDR radio for kicks, fun, and giggles. I have a Yaesu 450 radio now and like it.. I wish I was young and smart as I was back then, but still trying. You are doing a good job with this 3 parts series, which I shall watch and hope to get smarter ...

Dave does a wonderful job of SDR explanation with multiple examples and graphics. He also periodically reviews what he has shared which is really helpful. But be prepared to pay attention! The information is in depth and will require your full attention. Thanks, Dave! I look forward to parts 2 & 3.

Very good explanation of SDR technology and the SDR equipment that represents it. Regarding the needs of ham radio. In three parts it is very clear and matter-of-factly explained.
Good for everyone. Not only for those starting with SDR technology.
Solutions for different needs and pocket with different resources.
It allows you to understand the technical issues and the background behind those that will allow you to make the right choice and the right purchase decision.

You sir are a wizard. The knowledge you have chosen to share here will no doubt resonate with future radio enthusiasts on planet Earth . We all have a mutual respect for technology, however, the old-school format has, or at some point will become stagnant. The technology of tomorrow depends on good willed blokes like you Dave! Thanks!

Excellent! Subscribed! Two years after and absolutely valid, clear and understandable for a non-engineer ham. As are parts II and III. It's amazing how fast and how far the radio signals technologies (and our hobby ) have gone. I still remember my first radio receiver back in late 80-ties, a direct conversion made of 2 diodes mixer and a 3 transistor sound amplifier. It was bringing in good dx to my SWL log. And now I can ( and I am) come back to this simplicity of few parts in absolutely new world of digital chips! The thrill is just how are these few chips doing their huge job worth of millions of transistors and diodes ... The magic. Thank you! 73! Linas LY2H

Great presentation. As a kid, I was fascinated by the idea of radio and wireless communication. Now, as a software engineer, I plan on rediscovering the topic. Your videos are great resources for that. Granted, I'll have to rewatch this one a several times, but it's worth it. Thank you, sir

Where were you and this video when I was stressing through my exams? I passed but I end up with a railyard full of random boxcar's filled with knowledge. Now you've lined them up, in proper order to form a magnificent train. Thank you so much. I can't wait for the rest of this series 😍😍😍😍

[நடராஜா-தண]

Really amazing sir in school day we have assembled (valve radio)
really The Technology has developed,
once again we thank you for efforts taken of posting 🌷🙏

Great work Dave. I bought a 2nd hand FDM-DUO at start of last year and I'm loving it... I'm learning something new about this radio everytime I use it.
I first started looking at SDRs when I got to listen to a presentation from VK6APH Phil in 2013 about his work he was doing, this got me really interested but I've just started to have more time to play radio a little more now as family & work were higher priority at the time.
Thanks for doing this video series on SDR principles and history plus where it has the potential to go to, this is what keeps my mind going.
Cheers, Adam VK2YK

Splendid introduction! My sincere thanks for the clear presentation!

[salsamander]

Its simply perfect for teaching SDR basics and principle to my radio club! Great job David! 73

Thank you David, very informative I appreciate it, I just picked the Icom PCR-100 and I love it I’m always looking for SDR radios . This series shows you history and the Evolution of SDR software, , , and the theory of operation and layout off the you . Black Dog out 73’s.

I'm only 5 minutes into this, but I like it already. It looks and sounds entirely professional, and I suspect you are a pro. I'm an Amateur Extra who has been into RF since I was 10 years old 60 years ago. But while I'm well versed in electronics and I've built and use a couple of SDR's I always find that there are holes in my knowledge base. I think these videos will fill those holes. Thank you.

[steveallison]

Goodness gracious! You have a tremendous radio/narrator voice. Nice job on the video too.

[demofilm]

dear mr David thank you for this story telling manual. i learned a lot!

[brianhind]

Sir: An absolutely superb tutorial ! May I compliment you on your articulate speech, the rate at which you spoke, & your explanation of terms likely unfamiliar to many viewers. I was particularly impressed by the absence of "Ums, errs, & other "gap filler" articulations. Your descriptions of the various facets of SDR operation was simply excellent, without detracting from technical accuracy. You have a knack (sadly lacking in many teachers) for communicating the arcane Free Masonry of advanced mathematical concepts to those of us who consider the completion of an income tax form to be an arithmetical enigma. I look forward to viewing the remainder of your presentations, thereby being informed as well as entertained. Thank you once more.

[davidk]

Great tuition very helpful to anyone interested in radio, thank you.

[glenngoodale]

i do enjoy listening to you, watching your video's, and you sharing the things you have done

[joseluism.]

Excellent video. Congratulations !!!
I will watch the rest part2 and part3 . 73
