Appreciate your videos! Two pieces of software I love and highly recommend: SIGMIRA - lot of options for visualization and decoding of signals ARTEMIS by AresValley - Extensiv signal database to better recognize different patterns and which systems generate them, a ton of examples how signals show up in waterfall and also audio examples!
I have been slowly getting interested in SDR due to the obvious crossover with my other hobby of Radio Control flight and various long range control and video solutions. I have an old rasp pi and a dongle in the mail, I will def check these images out. Thank you for the video and the effort put into presenting all this info. I appreciate it a lot!
This is the first I heard of the MSI2500. It's perfect for the price, dynamic range, frequency range, number of filtered bands, and versatility. Plus it's cheaper than the RTL-SDR that I just bought.
Supposedly it’s a clone of the RSP1, i was surprised too, but after buying one, i can confirm it’s a 100% upgrade from the rtl-sdr, aaaaaand it’s cheaper!
@@howforless There are also some smaller RSP1 clones that use a single SMA, and have switches on the board to choose the bandpass filter. I bought one last week, and am having fun with it.
Hi John, note that I'm not using this with a Raspberry Pi, just using CubicSDR downloaded on a MacBook for now. I do want to try it on the Pi with a touch screen LCD, which was why I thought this video would be helpful.
@@BrightBlueJim, thanks. I'm not a software guy, so I know little about what works with what. I'll try my module with other hardware and apps. After pricing the Raspberry Pi's that are available now I was afraid I was just going to have to wait till production had ramped up beyond demand again in a year or 2. Unfortunately, I've finally deduced that my new SDR module is defective, and I was getting the run-around from the seller, so I've decided to order one from a different vendor and also try to repair this one.
I have an RSP1a and run uno I have found its good enough for 99% of anything I would ever need it for, I listen to everything below 30Mhz, all ham bands above that up into the 900s mhz, I also have a few other SDR dongles I have played with and can say everything else is junk, I will play with a Pi or a card soon .....
What I would like to see is someone or a group of individuals come up with a SDR based service monitor for the average ham operator. Basic operations would include frequency and deviation of transmitters testing as well as receiver sensitivity testing. Basics of a service monitor. Now there could be other specialized add ons such as decoding and encoding for digital modes (ie D Star, DMR, P25 etc.) pocsag encode and decode. Instead of R Pi based one could use some of the surplus mini computers available on e Bay. They are more powerful and might be able to handle multiple functions at one time plus it would have to have the capabilities of a true service monitor to handle ALL frequencies from VLF to at least 1 GHz.
Andreas, i love your videos! I've seen the price for the SpartanV6...wow, so expensive (nothing compare to a professional ASA, but for me is expensive a lot)! Thank you so much!
Even with my €900k lab I still love using the rtl sdr( yes got waaay more powerful toys( no cant use these if you got only ham license). Its simple it works, though my antennas 100% dont fit in a cuppboard unless I can get a 20m cuppboard😅
That’s a great idea. It was a pain to set up the software / drivers based on a Windows PC. Some stuff I couldn’t even get to work because it wouldn’t compile etc. This might help me get back into SDR.
I'm finishing-up my eighth homebuilt airplane, which sounds like a lot except that's over 50 years of building. This new one is a Quickie Q1 -- a VERY SMALL canard design. The entire instrument panel is an iPad that even controls an autopilot. But now I am interested in SDRs and wonder if I can use them to make aviation (118.000 to 136.975 MHz) transceivers? Of course I CAN, but should I? It's just AM modulation and I am properly licensed with an FCC Class 1 license (I was chief engineer at a commercial radio station at age 17) and the little plane has a radio license, too. I'm not a licensed radio MANUFACTURER, but surely these SDRs fit the technical requirements, so why not do it?
1. Nice little plane, and an interesting setup. I also had an experimental canard in mind (I even went for a test flight in Florida). But it was a too big project for me. So I admire your work! 2. Most modern radios are based on SDR technology. This might not apply to aviation because, as I remember, this technology mostly was "proven" and therefore old. 3. You probably could build an SDR transceiver. But AFAIK you are not allowed to use it. The right to build is only for licensed HAM operators, and only in the HAM bands. DIY receivers are ok in most countries.
I Iuse RTL:SDR V3 With USB Thats Like A Coax Cable, Its Trabnsparrent And You Can See The Mesh Like Wires Around It And I USe That, Friend Who Dumpster Dives Gave It To Me, Im So Thankful To Him :)
_Andreas to the rescue._ In future I'll refer ham newbies to your *Great Intro* . (anyway.better loaning my pi than fixing (yet) another _"Experimented On"_ WinPC) Btw: The usual chinese sources also sell _ "filters only diy sets"_ (...very useful with a better antenna on cheap rtl (imho))
Espressobin should have more IO bandwith than a Pi and used to cost about $70 for the board without a 12v barrel jack(5 to 10 USD) and a case /w heatsink another $10... so like $100 for a usable setup.
I agree. As soon as you leave the Raspberry ecosystem you get much more choice. But you lose the community support as well as many projects. I am just tinkering with a used thin client PC and proxmox ;-)
@@HB9BLA I disagree, I mean you are right that there is a kind of safety net when going with something well traveled. I just don't think it matters to the degree ppl might imagine. I would guess the superior IO more than makes up for the tradeoff of this device not being as popular.
I was hoping for a preconfigured OS that I can put on a PI that is remote and connect using a web front end. This is because I can put it up high and away from noise. I currently use sdr sharp and it would be good to still use that but it seems far too time consuming to set all of that up. VNC isn't really very good especially over wifi for realtime listening - it takes half of the PI just to stream the VNC desktop.
There is a raspberry-websdr github projekt that does that, providing a webinterface from which you can listen an controll, I set it up a couple of years ago and it worked well. Using the flash-and-go solution showed here, I would expect not too much of headache setting it up since the 'bad stuff' like drivers and such comes pre-compiled/pre-installed.
Hi there, I hope someone see this. I am doing the process for the rpi 5, in the git the image says it has rpi 5 support but when I go burn the image to the sd card I get “MBR DOES NOT HAVE A VALID SIGNATURE”. Does anyone recognize or know how to fix this?
Indeed, this is a marvelous device! I will not cover it in a review because it is too expensive for a hobby. But it might appear on the channel as a tool.
Very nice video again!! 👍👍 Thanks Aber ganz blöde Frage: Sie kennen sich ja ziemlich gut aus...wie kann ich mich dem Thema microwave cavity geometry nähern? Würde gerne die Resonanzfrequenz ua von "komischen" Formen, kein normaler Waveguide, bestimmen. Have a nice Week
wow very nice SDR Raspberry Pi video. I would like to use this information in putting together a 1420 MHz radio telescope and use the: Orange Pi 800 Six-Core 64 Bit 4GB RAM Dual Band WiFi Bluetooth 5.0 All-in-One Keyboard Computer Kit with 64GB EMMC, Run Android, OS, Manjaro, Ubuntu, Debian (Pi800+TypeC 5V4A Supply). I think it should do the job? There just is not very much Orange Pi information that I can find, such as installing OpenCV on an Orange Pi system. 😎 Thank you so much.
I do not know these products. The more you go away from mainstream, the more you are on your own. On my second channel, I showed another possibility: Used Thin client PCs from eBay. They are much stronger than the Raspberries at the same price... And they are mainstream.
Hello Andreas, can you check one thing for me please. Switching on the Rpi, do you notice the increased noise on the other radio, let say 145 MHz? I am running the RPi 3b+ with the openwebrx sw but powering the Rpi increase the noise on my other packet radio up to 59+20dB. The cause is not the switching power supply but the RPi. Do you have the same experience there? Thanks...
Did you wait more than one second? The display below the line IS a waterfall display. As with all waterfall displays, it can't show any history until it has some.
@@qwaqwa1960 A waterfall display is a spectrogram with history. That is all. It shows the spectrum over time. The fact that some people use this term for other purposes does not alter the fact.
Has anyone else found a similar video but takes it bid slower including every single step with a how to. Do I need to use the Pi4 keyboard in the video or can any USB keyboard with mouse work?
1. I do not know of another video. Maybe stopping the video from time to time helps. 2. You should be able to use any USB keyboard for the Pi (I often use a standard Logitech wireless one)
@@HB9BLA Thanks for your reply. This is a good video for those that are already familiar with using a Raspberry Pi and a SDR but might be advanced for someone with no experience with a Pi and a SDR. I have played with a cheap SDR on my Laptop and have that working but would need a slightly more basic video to use a SDR with a Raspberry Pi. I would like to try the board with the multiple inputs on my laptop assuming it is already available as a choice for plug and play to see if reception is any better.
Swiss distortion? I would dispute that but women on dating apps are using filters that make them look 15 🤔 I guess I’m going to have to take your word for it.
