Do you have the V3 or V4 dongle?

@@tunedsignal not too sure it says rtl dongle fc0012 any thoughts ?

RTL2832U QEM

Can't even hear any static. How do you switch it on ,?

@@Tmacker71165 sounds like we are dealing with a driver issue. What version of SDR++ do you have? You'll find the version at the top of the SDR screen in the title bar.

The balun has two holes for the wires to go in... There is a spring loaded button that you press which open the holes on the end. The spring button when release pulls the contactor to the wire and holds it pretty snugly. Note a 1:1 balun would perform better. Thank for watching... Stay Tunned

Not at all Morse code is a way to communicate with sound pulses. It originated as a way to communicate via telegraph, which is a "tapping" device you use with your fingers to produce short and long tones. Telegraphs were at the time connected via wires between places. Morse code (named after one of its creators Samuel Morse) is the name of the code system where each letter of the alphabet has a corresponding series of tones. Short tones are called dots (now called dits) and long tones are called dashes (now called dahs). (its also more fun to say dah dah dit dah dah dah note the space between the two series) The letter A is represented by a short tone then a long tone. Its written notation looks like this using the dashes and dots. A ._ B _... C _._. and so on.. There is one note... The code we use today has been updated from the original encoding method. It is now called International Morse code) You can find the complete code online .. check Wikipedia or checkout UA-cam videos. Something EVERYONE should know is how to call for help with Morse code. Using the internationally recognized code for help SOS (Which I have heard several acronyms for what it stands for) Commonly, SOS stands for save our souls.. The is simply the code for letters for S and O and would look like this _ _ _ ... _ _ _ It could save your life if someone saw the letters or heard you tapping in nearby or in the distance. Elmers jump in! oh wait.. I just realized I might be an Elmer... Thats an odd thought...

You are correct. I have found that new users just don't see anything so having higher gain allows them to start high and lower from there. The side effect of this is high gain also increases noise. In fact if you are dealing with a weak signal it can be lost in the increased noise floor.

This is a software defined radio (The RTL-SDR V3) with a ham it up up-converter Tuning low frequencies where many people communicate worldwide with Morse code.

@@tunedsignal cool thanky

OK now we're getting somewhere. First... We need to check the settings for audio at the bottom. SDR++ has the ability to listen to multiple channels via sinks. Take a look at my video on tuning into trains for additional details. Let us know what you find out.

@@tunedsignal I was able to pick up some noises with SDR++ and Sharp too, but not really useable stuff. In theory i didnt changed anything, but i will take a look again Thanks

Plug in your SDR and connect an an antenna. Start with FM radio That will be 88MHz -107.7MHz Be sure you are entering in the right number of digits so 103.7 MHz will be 000.103.700.000 You'll know you are in the right range if you see FM Broadcast in the FFT (the top middle part of the window with the peaks of the waveforms. If you don't see the labeled blue band AND you are in the right range.. make sure you have USA band plan selected and enabled in the Band Plan group on the left menu) You will need to set your modulation to WFM make sure squelch is NOT checked in fact the only thing you should have checked in the Source group will be IQ correction and in the Radio group select WFM as indicated above and NOTHING else for this test. From there move up to 117-128MHz Switch to AM in Radio... you should be able to hear Air Traffic control and aircraft communication. You can adjust your min and max ranges on the right so you have a nice royal blue.. lower your min value so the area in between the signals (your noise floor) is low-ish. You want to see.. I typically have the lowest part of the noise touching the lower line above the frequency labels below. The max slider increases the height of the peaks. I adjust it so I see a tiny bit of red.. a VERY tiny bit. Those are my preferences for looking at the waterfall... Others Max an min to their liking... bu you definitely need to get the noise disply under control so you can see signal and tune properly) OK OK Wake up!! Sorry for the long post... (ha) Let us know what you hear!

@@tunedsignal *First of all, i just wanted to say that im from EU, so a couple of things are different, but i have all the EU CB channels and stuff :) So, i tryed ++ again, but i cant hear anything but noise. Only works on phone, but im from PC now. SDRSharp works, i can hear FM, even romanian one now haha😁 A couple of air traffic too, so its working thats for sure. On CB channels i see a couple of powerful red lines, but however i change to AM-FM-USB, i cant hear anything. There are some rare really powerful ones i can hear, usually from the another side of the world, like how CB band travels to us :) But not the others sadly. In theory, someone used FM from around 20-25KM away, but i heard nothing, usually thats a distance where i still supposed to hear that with a long GPE27 antenna like mine. Thanks very much for helping:)

@@drakeblackk Ironically I was going to mention the odd vs even number for the FM range.. What version of SDR++ and what OS do you have? It is in the top menu bar of the SDR++ window.

I have since learned this... It's a bit embarrassing now... But What I have learned since is a 9:1 is good for a long wire with HF. The reason why it worked on was due to signal strength.... That said.. This is why I take a lot of time to make videos... Researching my assertions... Oh... Yes I can spell resonant and know the context of resonance ... Eek.. Sorry for the typo everyone...

I've seen that

I've heard of that. I focused on vocal coms for safety reasons. Be safe out there. Stay Tuned

Thanks. Be sure to subscribe and share with others to spread the word about this amazing technology. Be sure to watch the vids closely...😉 Stay Tuned!

Thanks! Stay Tuned!

What SDR do you have?

@@tunedsignal Just fixed it! I needed newer drivers. (RTL-SDR V4)

yep I thought it might be the V4 drivers! Congrats! I posted about V4 drivers in another comment thread. Stay Tuned

Greetings! Mission accomplished! I hoped my experience would inspire others. If you know anyone that might find it new and or inspiring.. share it with them. What SDR do you use?

CQ CQ CQ Stay Tuned In!

When I realized you could get more terrestrial TV channels at night and in the morning I thought.. wait.. signals travel farther at night than in the day. Oh an Radio Shack 😔

Thank you. I'm glad I was able to help. Take a moment to check out some of the other missions. I also posting a new video about how I got started in SDR. Stay Tuned! More Soon! I might just 13.56 MHz everyone...

Thanks for you response. You are correct, I didn't speak to antennas in this video. I do have a video talking about antennas for CB radio and I have learned a lot since posting that video. (as in.. balun types (blush)). Would love more detail if you can share it here. Thank you. Stay Tuned In!

I am naturally curious. I often want to know why or how something works. In fact.. I started thinking about data transmission at low frequencies and the limitations due to the wavelength. I'm still amazed that the wavelengths in HF can be 100 meters. That's simply fascinating. Then I think... "Oh one is passing by right now..." So, I guess my perspective is.. If you now know something and find it interesting, why not learn more. Stay Tuned!

I am actually looking into loop antennas. In this "inspirational/ aspirational" video I was using a long wire for HF. A loop is my next antenna. Do you have any recommendations? Thanks! Stay Tuned In!

It's interesting that you should bring that up. In fact approximately 75 percent through the edit, I realized that I was really highlighting and showcasing the software and hardware that was instrumental in shaping my interest in software Defined radio. It did feel like I was promoting those products, but truly, I am promoting the mission of Tuned Signal, which is to share, inspire and excite interest in SDR, RF. and radio. Most importantly I want to demonstrate some of the unknown signals that are around us every day. If anything. This is an advertisement for Tuned signal and SDR interests. Thanks for putting words to thoughts that I too had noticed. I hope this video inspires you to dust off your SDR and follow along with us.

@@tunedsignal not that there's anything wrong with that! if i drank, i'd raise a glass like Darren Stevens. cheers.

Thank you for the compliment. Your sentiment lets me know I have accomplished the intent of the video. I truly appreciate your comment. Help me inspire others with this video. Stay Tuned in!

Thank you. If you know anyone else who might enjoy the video, share it with them and hopefully they will be inspired to learn more about SDR and radio. Let me know what SDR you have and your interests... Thank again...

Interesting.. if you can start with short coax to limit losses that's your best bet. Also use pre-made coax with connectors. I'm not sure if you are making your own. Testing with manufactured short test cable can help you isolate where the issue is. Stay tuned

Indeed. All the cool kids do. Stay Tuned!

I've heard of that SDR. What makes it different and or better? Tuning into Field Day is pretty interesting.

@@tunedsignal its got a very wide range, dual rx, dual tx, and many more features. It was designed as a development platform for engineers creating new products using analog devices chipsets (analog devices are world leaders in this field) and it can be had for 250 euros.

Oh my... I would love to check one out!! Stay tuned!

Wait... There is something even better? 😯 I must see this.. I'm really concerned about noise... It's my latest obsession.. Stay turned!

@@tunedsignal the Hermes lite 2 is a $350 sdr that is a 5w hf ham radio. The learning curve of software setup is rather steep but it is one of the most powerful ham radios on the market being totally software run. Direct sampling, 384khz at a time bandwidth, 0.5-30mhz direct sampling. Most people run it with Thetis on windows, I’m running pihpsdr on Linux it’s a mini super affordable version of an Apache labs or flex sdr.

Im rather partial to SDR++, but 5W tx is impressive. Thanks for the tip. Decisions Decisions!! Stay Tuned!

Godly...

Thanks for the compliment. I can't imagine the amount of interesting signals you are seeing in Poland. I'm glad you enjoyed the video.. I hope it inspires others. Share it with others, maybe it will inspire more people to check out SDR and radio. The more I see the more I realize there is to learn. Stay tuned.

😂 It could be. The RTL-SDR V4 is a good and inexpensive way to start. However you will want to look into an SDR Play or similar in the future. They have amazing performance.

Thanks for the kind words and compliments. I truly am inspired and amazed by these devices. If I can inspire and help others that would be great.

Thank you. Othernet is a small project with big hopes. It really got me tuned into this whole new world. Sometimes I wonder what signals are passing overhead that I am missing....

I've found this entire experience to be more of an art. It's still fascinating that some people don't find it interesting. Radio is magic and software defined radio is modern magic we can all conjure.

Thanks for the compliment. I hope this inspires you too! Now if I could only tune in the 70MHz range just right I might have something memorable... Stay turned!!

I played with a crystal radio as a kid. I still think they are magical. They are very simple.... Thanks for sharing that memory... Its given me an idea. You're right... those same moments of discovery are very similar to my SDR experience. Stay tuned!

@tunedsignal Same experience yes! Keep up with great videos.

Thanks... I hope you have and will be inspired by this a future missions

When investigating possible missions some don't pan out. This episode was started with a few other ideas simultaneously. I am quite busy with work and sorry the time scale doesn't meet your expectations. I also don't want to push for money from supporters if I don't have to.

Your post got me thinking... Would you be a paying subscriber with weekly videos of the same quality?

Thank you. More to come.. I truly appreciate the compliment. Let us know what signals you find and what you are looking forward to in future missions. Thanks again!

Thanks for tuning in. I have more information coming soon. I am compiling it as we we speak. Let us know what you are looking forward to with your SDR or other digital radio...

I created the video before the V4 was released... I have 4 V3s The V4 is better for lower frequencies, but has little lower signal strength than the V3.

@@tunedsignal i bought the v4 because i wanted to hear the lower frequencies. i already decoded noaa apt signals and got a nice image for a first try.

There ya go! I need to compare the v4 to some of the gear I have....

Awesome. Im glad you were able to gain some insight from this mission... More to come soon! Stay Tuned!

Hahaha! Welcome to the mission! Tell us what SDR you are working with good buddy.

@@tunedsignal Right now, I'm reviewing the options. Almost ordered a $$scanner$$ but came across an SDR usb-shtick to do the same thing I wanted. Very small town here all authorities use FMN (analog?) being very curious to all the drug busts and other dopehead things that go on around here. Setup & programming RTLSDR doesn't look complicated actually may be a fun challenge...10-4

@@clutch5sp989 It will be fun... Check out the other vids (specifically the one on trains) you probably have train coms to... I heard some crazy stuff a while back. New missions coming .. were just getting started here. Stay tuned good buddy!

Hello, sorry you didn't like the music. I include music running and very low to keep the mood upbeat and engaging. Also with music the videos don't sound like a lecture or news program. Stay tuned! I hope the content was helpful.

@@tunedsignal then make music videos. Some of us have hearing issues and you destroyed the content. It's a form of discrimination.

Its possible it will work.. Just make sure you are running the latest RTL-SDR V4 driver and that you swap the driver file in the sdr++ folder Note: I probably think about SDR too much.. Some might consider me... tuned in.

Thank you for the compliment. Software defined radio is amazing... More to come... Stay tuned!! We're getting ready to take off!

It an issue with setup of the SDR. I am finishing up a video on it now. Stay Tuned

@@tunedsignal Thanks for your reply. I look forward to your insight.

I will, provided you follow the setup of the V4 as detailed on the RTL-SDR.com site.

@@tunedsignal Thank you.

Hey how are things working for you now?

@@tunedsignal Hey! Still using SDRSharp on PC, but SDR++ works on phone :)

@@drakeblackk Which RTL-SDR do you have? V3 or V4?

@@tunedsignal V4 :)

You probably need to update the drivers for the V4. You likely have the older V3 drivers on your desktop. I was actually working on a video about that and decided to release another one first....

Let us know if you hear anything interesting.
