I forgot to mention in my first comment, that I had recently acquired another SDRPlay SDR Rx clone. Basically, the same as yours and the single port version I previously described(using both Msi001 and Msi2500 ICs). This version is also a single sma port style , but employs two sets of dip switches to achieve the multi port functionality that you described the Rx in your video as having. If you know of any documentation for the two clones I’ve described (other than the data sheets for the two ICs) I’d appreciate any guidance you can provide. Thanks for your time and work that go into your videos. They’re are an excellent educational resource for late comers like myself.
I have seen that and shared a phot of it here notebook.hvdn.org/2024/09/controversial-sdr-plus-3-d-printing.html but did not want to complicate the video. If you look at the schematic here its interesting how things are set up which make this version likely better as single purpose radios dedicated to specific spectrum. www.aliexpress.us/item/3256804660151348.html
Nice video. I have the single sma port bootleg SDRPlay Rx. I blame that on Amazon because you have to really look to determine that it’s not the genuine product. That being said, it was a while back when I was just getting into Software Defined Radio and was use to Analog Devices and Michael Ossman releasing their SDR stuff open sourced so I thought that was the standard. As I continued to learn, especially by learning the Dragon OS Linux Distro I finally figured it out. When I realized it was not genuine, i ordered a couple of Rxs from SDRPlays website. It’s funny you made that case, I just finished a basic case for my Rx mainly because I just got some of the new Fiberon PETG-ESD filament. I did my entire design in Prusa Slicer. I started to do it in Fusion but just saw a video of how certain things could be made in the slicer alone and it worked. Yours is way more detailed than mine, and I like the lighter color. Thanks for the video!
Hello from OZ2NO The link for the SDR does not work. Could You check it again and link it here. I have been Looking for A good Sdr Software for years. And about 3 week´s ago your video on SDRangle came in my feed And now I don´t have to look for A good SDR software Because SDRangle Is the best there is. I wonder why it is not well known as many of the others SDR Software Good Day
Hello from the PCARA club, W2NYW . I just bought a Raspberry Pi 5 with 8 GB, to use with my SDR V4. I did down- load the Raspberry Pi 5.0 with SDR book recently. 73 de W2CH Ray and KC2NKU Marylyn now in NH, but will be back in Peekskill in late November.😅
I don't use windows a lot, but I am trying to get SDRAngel working on my drafting computer. There is so much missing in the Windows version. I can't figure out, if they just didn't build it for the windows installation, or the plugins I'm after only work in Linux. I want the KiwiSWR and Map plugin. ADSB his hard to watch without the 3d Map.
The Windows version is 100% compiled the same as the same Linux Version. Which "features" or "channels" are you feeling are not there? You could also have some issue with video related to OpenGL or something in Windows environment creating an issue, but I find that is rare on a modern (post 2019) computer. Message me direct as I am working on a video I may want your input on at k2gog@hvdn.org
I had not checked for that, but if it does it is likely meant as a type of ventilation. The casings for the HD1 and HD2 plus chassis are not very different from each other. Why do you ask?
One of the best tutorials I've seen, it's clear and simple. I just have a question how to save the workspaces? I carried out the manipulations on the registry, carried out a new installation... but I cannot find where to save! I am in 7.21.4. Thank you in advance for your help.
Have a look under "preferences" and the bottom of the list should be "Save All" The trick is before you exit out, get all your workspaces and other features/channels set the way you want, then save. When you open SDRangel back up, it should start up how you last saved things. I am going to do video soon about this so keep an eye out.
I ran APRS faithfully for 10 years while driving over the road. After all that time I got bored with it. People not answering messages, even if they weren’t driving. Digi-Peaters running the standard 100hz tone, not using proper SSID’s, & several other problems are what I saw with it. I tried to correct these things with some stations but got told mind my own business. You made a small mention of the digital mode M17. Between D-Star, Fusion, DMR, P25 & NXDN why on earth do we need another digital voice mode? There’s no radios manufactured for it yet, that I know of. As well as the thousands of TG, reflectors and rooms with nobody in them I just don’t get it.
What OS are you using and please say your on a 64 bit computer. You should not have much trouble using SDRangel on Win10 or maybe even Win7, but I run Win11 and Ubuntu these days. If the SDRangel logo appears after you click the EXE, maybe give it a few moments to fully start. If I new more what spec your computer is, that could help.
Hi sorry for the noob question but I'm having trouble typing in 7.048, when I type 7 into the first box the digit changes in the box before the one I type where the 7 should be, what am I doing wrong please? Thanks
If you click your mouse into the frequency box, try using your up and down arrows to change frequency and then use your left and right arrows to adjust to frequency of choosing. One thing that may take getting used to is display is in kHz and MHz, so 000,007,480khz instead of 7.048 MHz. When you get higher in frequency, like 1.090 GHz, the display will read as 001,090,000 kHz. Hope this helps. As you use your arrow keys, you should see the background color change on that digit too.
are you on a 64 bit based computer and version of Win10? You should not have much trouble using SDRangel on Win10. If the SDRangel logo appears after you click the EXE, maybe give it a few moments to fully start. If I new more what spec your computer is, that could help.
Hey man, Im also in the. Hudson Vallwy are, and have been into SDR and for a little while now, itd be dope to meet someone who actually is about it and knows their stuff especially irl. I can give you a link to my socials or if you wanna communicate thru a meshtasstic or something first i understand. Im just stoked someone is actually near me that i can Learn from and get in to actual discussion with. Btw my names mike :) hope ya repLY 👍🏾
Hi Mike. Keep an eye on one of my other club sites at undr-group.com for upcoming in person events. We have not done any new in person things with HVDN yet but may be relaunching some virtual events soon. Also locally, Squidwrench maker group might be worth finding. More than a few SDR and meshtastic people there as well. Take care.
The RTLSDR V3 device doesn't show up in the drop down so I can't add it. I've manually copied the RTL DLL from the SDRsharp directory (SDRsharp is working btw), and restarted SDR Angel...any ideas?
You may need to hit the refresh button in SDRangel. Or, your system may be thinking your SDR-RTL V3 is still in use by another application like SDR#. Make sure that is not running and try it again.
Fascinating. I just stumbled on your video, and can't say I understood more than 20% of what you were doing. Are there many amateur radio operators sending out Morse on radio? Why? What are the messages typically about?
Hi there and welcome to the channel. Morse code is still popular. Most communications between people are usually just exchange of callsigns, signal reports and basic information. Others may include people who communicate using portable equipment from parks and they typically share a special park location numbers. Others may send more detsiled information like a conversation which is known as ragchew. Some organizations like the ARRL also broadcast bulletins about news and space weather. Have fun. Its an interesting topic. Please have a look at other videos to fill in the blanks. :)
Thanks for the latest video. SDRAngel is so feature rich it can be overwhelming most of the time. Since finding your original videos on the topic, I’ve learned so much. This new Morse decoder is yet another great resource I have to learn. I’ve been hoping to see a new video release on your channel and here it is. Thanks for all the time you put into sharing your knowledge. I look forward to the next video and the one after that and the one after that.
Even though i did the video based on a Win11 install... I do have this running on 22.04 on same machine. I had to compile manually and that takes a long time to do.
A few steps 1 - You need to reserialize all 5 SDR inside Kraken so they are recognized individually. 2 - Each SDR in Kraken will function like any SDR as these are just like RTL-SDR V3.
Sometimes an AMD based computrr has issues decoding digital modes compared to Intel ones. Its a complicated reason why to explain though. Also. What SDR are you using? Stability is important. Sometimes you need to tune slightly off frequency using the shift feature or adjust local oscillator adjust.
Is your antenna vertically polarized? Looks like a great setup I want to make for my limited space. I may use 450 Ohm window line to take the weight off the wire, and a 4:1 balun. Thanks ,and hope to hear you on the bands😊
technically this should be horizontally polarized based on where am feeding the antenna, but low to ground it may get reflection from the ground changing things slightly. My 20m delta loop at home in the trees gets about same signal reports but its not as portable as this one.
The feed point and mounting arrangement would need to change. If a square loop is fed at the corner, it would be close to 50 ohm and each side would be close to 18 feet, so would need to be mounted like a diamond shape if using one center support and some spreader between the two far points horizontally. Feeding the loop at the side would give it different polarization compared to top or bottom. For radiation related performance, it depends how high off the ground it would be (if we are sticking with 20m operation). It may work slightly better due to capture area but then this is a different type of antenna that takes up a bit more room. Nice user name btw. :)
@@hvdnmedia IIRC, the Delta Loop is about 200 ohms at the feedpoint. So another benefit would be that with the square loop you don't need any sort of unun or matching network.
how do you know what frequency to use? i live in richmond, va and tried different frequencies for RIC, but none of them worked - i didnt get anything (:<
I can't thank you enough for this video. Absolutely great information as a beginner to sdr you're making it easy to understand just wish you had the antenna connected liked subscribed.:-)73
You ain't kidding it's complicated 😂. I was using 2 monitors last night and it's still too busy. I just started using sdrangel, I've been using sdr# and sdr console for a couple years. I've run into a couple issues with angel so far. When I set my bandwidth to 2.8 or 3. MHz it's not recognizing it on the spectrum I e. Only showing 433.100-433.500 when setting it , the spectrum appears to make the change but then doesn't reconcile to settings. This program is a steeeeep learning curve, so thanks for these videos! They'll definitely help. I like how angel has all these demodulators built In. 2-3 years of glitchy sdr# and their plug ins working only when there's a blue moon and I switched over to console But even that's limited compared to angel!
How do you think they afford to sell these things so cheap? Because they barely build them with the bare minimum. Hams should be ashamed of themselves for buying this junk. Fun to experiment with I suppose. But that’s all they’re good for. So this radio is illegal to use in the US, minus hams I suppose. But I believe that’s a serious gray line we’re floating on. The purpose of being exempt isn’t to buy cheap Chinese non-type accepted junk. It’s to build our own equipment to experiment with. They will never try to improve on this stuff. It increases the cost too much. They’ve had years to improve on these radios and they refuse to do so. If they haven’t done it by now, they’re never going to. God forbid the put metal shielding on anything, it’ll cost them an extra $.0001.
This video proves what I’ve been saying all along, the cheap Chinese radios are junk. Harmonics being transmitted all over the place. Who knows where, possibly public safety, commercial, or even military frequencies? Yet this group continues to push or encourage the use of this junk. I’m curious why you didn’t test one of the most popular radios Anytone 878 UVII Plus? I know the one Alinco you tested is a derivative of that. Several years ago I used to check into the STEM net. One night I followed a couple of you guys over to another talk group after the net and listened to you call me a “radio snob”. “Who does that guy think he is ?” Call me a radio snob if you want it doesn’t matter. But I only buy “real” compliant radios. The same exact reason I won’t buy something like a G90. Thank you for proving me right all along. 73 de W2ITG
@@truckinguy92 I don't know if it's intentional...I would guess they'd like to sell as many units as possible, and I would guess when word gets out, at least hams would be less likely to buy.
@@hvdnmedia I worked that out. It’s been a few years since I added the RTL-SDR to a win 10 machine. One forgets these things over time. Zadig isn’t a driver, it’s an application used to change the driver to one that works. Next step is to see how SDRangel works.
Yup and hams keep buying them again and again and again and again. That’s why they get away with it. If hams would put their foot down and say we’re not going to buy this junk, they wouldn’t have a market to sell it to.
Thanks for the review comparing and showing the design and structure of the Ailunce, (Retevis), HD2. As I told you previously, I have had an HD1 for a while, which I think came out in 2018. It seems like it was one of the earlier DMR HT's aimed at amateurs and not just the commercial ETSI market. I did not know the FCC ID no you asked me about previously was not real. I find mine outputs about 8 watts on VHF, and about 6 watts on UHF. It took me a while to understand the DMR Code Plugs and do my own. Also, I took some on line Tait DMR on line courses a few years ago, which is more DMR commercially oriended, going into Type III DMR, and Lan, than with amateur uses. 😊
I did a very unscientific experiment, comparing my ID-52 to an HD2 to. These were the results on the first 3 harmonics: ID-52 146.4 -51dbm 292.8 -97dbm 439.2 -96dbm 585.6 -108.3 HD2 146.4 -51dbm 292.8 -85.7dbm 439.2 -61dbm 585.6 -91 I used an SDR, set the gain setting exactly the same for all tests. Yeah, obviously not seeing a 40db attenuation on the HD2 on the second and third harmonic.
Thanks for your measurements. Will give you a shout out in upcoming video where am doing the same thing mostly. Had to do the other two first just posted comparing the HD1 to HD2 and a basic inside look at the HD2.
