Keep in mind, that most aircraft communications (and services for them) utilize the AM mode. In your video, you had it in FM mode. Good job on the video, otherwise. It is nice to see that exploring radio no longer requires expensive radio scanners.
The feedback is much appreciated. My primary reason to get the device was to capture air traffic signals, and I seem to have a better luck capturing it on the WFM signal. I tried to specifically search for the information you just stated but was presented instead with countless unrelated answers. Hopefully, viewers will find your comment helpful.
That's what I came here to say. 🤣🇦🇺🖖
For HF, you need a LONG, long wire antenna, an SMA to long wire balun, and AM and FM broadcast notch filters.. and know which sampling to use.
Thanks for sharing this video ! I just ordered one on Amazon with delivery estimated in 4 days.. This will be my second SDR.
Hey Steve, thanks for tuning in! Great hobby with a lot to explore. Once you're comfortable using it, you can explore the wideband LNA, which is a device that works with SDR devices and helps capture satellite images.
Fantastic video, thanks for taking the time to produce it!
Thank you so much!
This is a very informative video. The installation portion has been especially useful to me. I can that tell you have invested a significant amount of time in research and production. Thank you and 73s!
I appreciate you, Stephen. Very kind. Thanks for dropping by. 73s.
Many Thanks, you've been most helpful in getting me running 😀
Thank you so much for the feedback!
Greetings from Sweden! You, Sir, just got yourself a new subscriber 🎉
Thank you so much, Phil! Greetings back to my viewers in Sweden 🇸🇪
Fantastic information and thank you for sharing this information it's very well presented and easy to follow. I had to sub as I would look forward to any rmore vids.
I appreciate it! I'm glad you liked it 😀.
Big thanks for this video !
Im going to order this weekend Im excited to start using it
Order on eBay or Amazon, Aliexpress will delay shipping due to the Chinese spring break. Let us know how it goes once you set it up.
@@RandomTeq I definitely will and Thanks for sharing the links too I appreciate it I'm going to start using it with my Ubuntu/linux machine
I have a video coming soon on signal strengthening device for the SDR, more stuff on SDR if you enjoy this one.
@@RandomTeq Sounds good I will definitely be watching as I'm still new to this stuff good videos by the way
thanks for getting me up and running...i am HOOKED !
Pleasure 👍 🙂
The antenna is completely in the wrong place! The PC interferes quite strongly on many frequencies. It is better to place the antenna as far away from the PC as possible.
Hey Michael, Thanks for the advice. I've had a better signal when away from the PC, but I just attributed it to a bad signal. It makes sense.
@@RandomTeqIt’s better to put antenna outside
Good information video!!!! This will help others to get started in this wonderful hobby!
Very kind of you!! Thank you so much.
Great video. Thx a lot 😊
Much appreciated. Thanks for dropping by.
Great introduction to SDR. I'd like to see some more vidios on this subject. Pulling pictures from NOAA satelites is what I'm currently trying to perfect, with the GEOS satelites being next.
I made a post on Reddit earlier and got some suggestions that made me realize that the SDR possibilities are huge indeed. Thank you for your encouraging words, very kind of you.
For "me" it was very simple to set up. #1. Radio Software download. #2. V4 folder download. #3. Put V4 folder inside of radio Software folder. #4. Open radio Software. #5. Plug in V4 to USB and press "play" on the radio face.
Nice job RT. I was wondering if you would be covering or have covered pairing two V4's through one antenna to pickup P25 communications, since most bigger cities are ditching Analog and going digital..........thank you!
Hey newtron, thanks for tuning in. I'm not familiar with the subject, but I'm up for the challenge.
Best video I've seen on sdr,.
Thank you so much, Bob!
Good video to understand principles of device. But what if I need to use it as signal sender in variations of range instead? Is there options available at all or should I look at some different products?
Hello Vitaly, Just made a video on handheld radios, I would recommend the Quansheng Radio, it covers the entire spectrum and the most range for transmitting signal. amzn.to/3v4NE22
I'm trying to run in Ubuntu 22.04 LTS but am having difficulty installing SDR Sharp. Any suggestions where to find LINUX instructions?
Ubuntu always seems to have issues running SDR Sharp since 20.04. Here is a solution I found online: Install WINE via apt. Install dotNET 4.8 via winetricks - force Install the Verdana font via winetricks Here's an article/page, 5 months ago, by a self-proclaimed Linux guys detailing how to run SDR Sharp with screen shots on github.com gist.github.com/grahamwhaley/094d62d88575141377f02fa92342fb7e He doesn't say which version he ran it on, but I will assume it works on the latest linux. Hope this helps.
Meh just use GQRX.
I checked it out, It seems like a good option. Clean interface!
Hi !! Greetings from Argentina !!!!!!! How can I use two Baofeng BF-999 and two arduinos to transmit and receive data over-the-air ?? Thanks !!!!!
Hello Rodolf, Thanks for dropping by. Unfortunately, your request is beyond my scope of knowledge. Here's a video that I found on how to transmit data via baofeng: kzhead.info/sun/hZahgaWun6OugaM/bejne.htmlsi=YOO_PUCAdJJZX5j2
Great Video as I have been struggling to get this to work. I think I found problem but not sure where to find the .zadig file as it doesn't show up in my folder and when I try to run app it says device cant be found. I am a lot closer now with your video and I thank you for that and I too have now subscribed as your explanation is very clear and concise!
Im glad I could help. Go slow with the installation and be sure to run zadig as an administrator. www.rtl-sdr.com/getting-the-rtl-sdr-to-work-on-windows-10/
It ran but I pulled the antenna to make sure is picking up from there now it doesn't work DeviceMgr Says device is fine did I just burned it by pulling the antenna? Update: needed to specifically eject the RTL then it saw it again
I'm glad it worked out.
I have 2 V3 versions that work fine but the V4 black version does not bring in any signals. Is there any software switches or settings I may be missing?
Do you mean it turns on, but you can't capture any signal?
It turns son and captures signal but nothing strong enough to use. Might have a bad one..@@RandomTeq
Increase the gain, its low be default.
Pretty sure the V4's need it's own driver, not the one for the v3
I just ordered from ebay !
Awesome 👌
What about the sdr-sharp for android version?
The company that owns the software "air spy" doesn't make an android app.
I got Error ''Cannot access RTL device'' problem. How can I fix that
I get this message when I forget to plug it to my PC. It simply means that it's not connected.
I believe that SDR will be mainstream very soon , it will be become very popular and quickly accepted .
Both your computer and monitor most likely are emitting a ton of electronic noise being that close to the antenna
Correct, moved it away from the computer, and the signal improved. A comment suggested it earlier and it proved effective.
I got this kit and signal reception is horrible, I'm close to some powerful stations and all are showing up weak, so far not impressed even a little. Tomorrow I'm going my SMA to N connector should be here so I can try a better antenna but this shouldn't need it for FM.
It takes a little bit of tweaking. If this is your first time trying it, I would suggest you adjust the settings. If you're using Airspy, make sure you crank up the gain. (Look for a horizontal bar with the heading" RF Gain"). If this doesn't work, share a screenshot of your settings on my Instagram.
In my part of the world (Pittsburgh, Pennsylvania, USA) 99% of police, fire and EMS calls are unencrypted analog UHF-FM. This SDR would receive them (and a Baofeng UV-5R is useful as a "scanner" here too!) and It's 100% LEGAL to LISTEN here! (in fact you can get the police frequencies for free from the US FCC database!) In the US it IS legal to monitor UNENCRYPTED police calls. (some states ban MOBILE scanners, But Pennsylvania does NOT).
US is generally OK, but it never hurts to check your state law. I added that part of the video because RTL SDR did have a similar article. Thank you for tuning in. Best of luck to you.
Folks should absolutely check their national and local laws! (I know that some countries outlaw police call monitoring, for example.) Luckily in the US, it's TRANSMITTING without a license (or with the wrong license/equipment) that will get you in trouble. If it's unencrypted over the air radio, you are usually fine LISTENING here. But that might be vastly different world wide.@@RandomTeq
The only way to pick up p25 encrypted is with special permission and the code to do so, which is extremely rare. So check with your county and or city to see if theirs is encrypted or not!

Oh my God, this is full of inaccuracies and incorrect information
What did he get wrong?
So many things in this video that are completely, fundamentally wrong. They don't understand the relationship between frequency and wavelength, they don't understand modulation, they don't understand propagation.
