Thank you. When you get your SDR.. you will have your first mission. The significant skill you will have will be calculating and creating your own antenna. This can be applied to ANY frequency. With a little digging you'll find other variations of the calculation for certain situations. Interesting note. There are frequencies that are easily monitored with an SDR. Know which, how and when are important. Stay tuned for an upcoming video on this subject.

I followed your instructions and for the 1st time I listened to a ham radio operators' conversation in the 2-metre band!!! I have no words to express my gratitude to you! They were two operators in my area, one in my city itself and the other one in a nearby town. Thank you very much! I will save your settings for future signal searches. Yet I believe that a blow of luck helped me. I cannot see any other signals in the band right now. 2-metre seems not to be too popular in my area. But I will keep persuading. Also, I think I should buy a better antenna (encouraged by the success). Thanks again! 📻🎧

Are you using sdr#? If you're not getting many signals with your sdr RTL go into settings in sdr# I think it's the radio or source menu and click on Q Branch. It's automatically on quadrature, when you switch. To Q branch holy moly it opens up so many more frequencies. I think people use those HAm it up devices to access more frequencies. All I know is when using q branch I get way more signals in Short wave , CB, like hundreds of signals from all over the world. Lots of people yelling about Jesus 😂

Hey there! Just subscribed. I felt that I should mention/ask about the dipole orientation. Im new to SDR but I saw a video a while back ( I can provide a reference if necessary ) where the guy says that the grounded wire is the one with the clear coating on it, and it should be facing the ground. What is mentioned in this video makes more sense to me, as I work on electronics in my spare time ( also Chemistry ) and a lot of the times the grounded wires are bare metal. So I wonder which orientation is correct? Great work @tunedsignal Hope you will be making more videos soon.

Stay tuned.. I have something for you. The antenna orientation is can matter when you have weak signals... You *could* when elevating the poles vertically alternate them and notice a little difference. Others have mentioned it doesn't matter... I'll have to reach out to an electrical engineer in radio. Thank you for the compliment.

It's been a minute since I've been out your way. Last time I was there I was near Kodak... Are you all set? Hopefully you were able to tune into some signals. The big thing is to start with the defaults, them make small adjustments. A lot of people make a lot of changes and get stuck, not realizing they changed something that wasn't clear would make thing confusing... You got this... If things start to seem to not work... you can backup the SDRPP folder and then delete the config.json file. when you restart SDRPP it will create a new one with the default settings. There are also some other files that save settings... If people need that info .. I can create anther video for the missions.

@kgabris3387 4 ай бұрын

You forgot to mention that many of those strong signals are illegally using power amplifiers. Legal transmitter output is 4 watts AM and 12: watts SSB. At night time when the noise floor is is much quieter is when SSB shines for CB and ham. The s/n ratio is increased and to hear those weak stations you simply crank the volume. Horizontal polarized antennae also reduce the the noise by increasing the s/n ratio. I believe CB radio will get popular again. It has a unique charm to it that online chat doesn't have. So easy to meet up with friends for coffee building face to face friendships vs.sitting at home all night in your pajamas. SDR is great! Essentially a wide range - all mode receiver for a fraction of the cost of a tabletop shortwave or scanner. Remember every band you monitor ideally requires a tuned antenna as the author of this video has illustrated for us. Enjoy? 73's (salutations)

Once you learn how important the antenna really does matter and you apply it... It really makes a big difference in what you can receive. So yes... you to noticed how silent it was.. Secret... In my tests since that video... You can use the kit dipole and some wire (on both poles) to extend that antenna to the same length and get similar signal strength. Then you don't need to get a balun... ;) Also... you can use two trees and string to elevate the antenna ti avoid the light stands... I wanted a portable anywhere option. Thanks for the compliment!

Great Video and informative. I'm new to the whole radio stuff and did some basic stuff with the starter kit like NOAA APT signals, ADS-B and Radiosonde... I also were trying to receive CB unsucessuflly, so maybe this video will help me with such. (I Guess I have to by a balun) Recently I'm trying to build a 70cm Yagi Uda antenna out of some thick wire and a wooden stick to receive some sattellite communication, I was able to get some signals especially from RS-44 and the Tevel sattellites, but most other sattellites I dont get any signal, or just sometimes some bursts... I've also read about digipeaters and packet radio, but so far were unable to receive any packets. I now build my second version with some alluminium pipe and a pvc pipe, and also adding a 2m band yagi uda, I'm hoping for some better signals then. But this antenna should be just as sutable for terrestrial signals right, do you have some ideas/tips on what to look for in this band... as its rather larger compared to the RTL-SDRs tuned band... which makes a "just glimpse at it" approach rather difficult... Anyway, keep up the work! Its a nice cut, you get the information you need, and not much unecessary stuff, right to the point... which is quite different from the videos of other creators, as they seem to have a rather "conservative" approach on presentation... but yours are quite mordern, with sketches, real footage, and a "arc" of "what a beginner would do" to "what you should try next" in a logical sense... without just saying, "well the dipole in the kit is shit, dont do it, instead, buy this hefty antenna" or "you gotta buy all this fancy gear to DIY your anntenna", its grounded and easy to understand for beginners... I'm also always kinda confused about people saying "go buy a proper radio and start talking", 1. no license, no talking, duh... 2. "buy a proper radio" its expensive, and often tailored for a specfic use case, isnt that the nice thing about an SDR, we can pretty much decode anything that happens in radio waves, and the RTL-SDR is very cheap, allowing for beginners that just want to "test the seas" easily come onboard, rather then having to buy expensive gear beforehand to try stuff, and check if they even like it or not >.> Can't wait for more content from you ^^

Thank you .. You're in the right place. The next thing is if I could get everyone to see the extras that are right here. SDR is a gateway to signal analysis and other skills outside of voice. I have something you will appreciate. Meanwhile, you can try without the balun and use a toroid. That's a ceramic semi-metallic ring that you can wrap the wire around several turns to help change the signal before it gets back to the SDR. It will do ok in a pinch... Without the balun.. Be sure to ground well. The first three videos cover a lot of the important basics. Your next mission... I believe it will inspire you to seek the unknown. After all.. most of the signals out there are not voice....

There are websites that have Solar Activity charts with Forecast of upcoming conditions effecting Skip, distance, direction, channels / frequency, etc. Antennas/Antennae. a lot of ppl talking bout EFHW end fed half waves. So instead of the 2 halves of a dipole, just one. I use an inverted V dipole, and a cross between inverted L and wondering long wire. Always fold over the last 3 to 4 inches of the wire, it will lower the noise-floor, and reduce the chances of lightning strikes, not perfect, but does help.

@tunedsignal 11 ай бұрын

@@MrIMacro I understand. I'll create a full build video. The basic steps for the build are as follows. Measure a of length of CAT5 wire for the appropriate lengths that you're trying to tune. Use the antenna calculator to determine how long the wires should be. Be sure to include an additional inch... You will trim later to the proper length after stripping the wire. Strip the cat 5 wire to expose the internal twisted-pair wire. Then untwist one of the pairs. (This takes some time). Once the twisted pairs are untwisted then you should trim it to the correct length for that frequency and strip the insulation off of one end of each wire. You'll be connecting the wires to the SDR with a balun that's indicated in the video. You will also need an adapter to connect between male and female SMA connectors. Check the links in the video description. You'll insert the stripped ends of the wires into the plug holes on the balun. Once this is all set up you're going to need to elevate the connected wires and the balun. You'll need the SMA extension cable for the SMA connector to be able to connect the balun down to your SDR . In my build I've used 3 stands to elevate the wires but you could use two trees and some string to connect the wires. You do not actually need the center light stand to elevate the balun. It can hang freely if you have it taunt. Once connected.. tune in and enjoy. What's great about this field is you can build an antenna for varying frequencies just by using a different calculation with the antenna calculator link in the description. It should be noted that speaker wire would be a lot easier to use because you don't have to go through the untwisting part. But the braided wire in speaker wire is much thicker and won't fit into the balun. Also.. I'd recommend a 1:1 balun if you can find one. Also.. there are baluns with screw posts that may be easier with speaker wire. 😉

So far, this RTL-SDR dongle has been the fastest and most effective way of wasting my money in exchange for disappointment. I wonder whether I should shell out an extra $$$ on a better antenna. Or if there really are 2-metre ham radio operators in my area (Curitiba, Brazil). The fact is, I can't hear anything but the regular, commercial FM stations I don't give a damn to. I just tried the little rascal (the dongle) in an open area where radio signals would potentially hit the antenna. No joy. I _knew_ I would be a bit out of luck with regard to the CB, although my city is crossroads to four important highways (truck drivers usually like CB), but no 2-metre (or any other) reception was a killer. Colour me frustrated.

May I suggest you to record videos with detailed instructions like the one you gave me for each band and transmission type (FM, AM, LSB, and so on). Or am I asking too much? 🙂 I have a fairly good knowledge about what repeaters are and how they work. Incidentally, I have just tuned one. There was no conversation, just a recorded voice message announcing the repeater so that operators could identify it. I caught the message near to its end. It is transmitted periodically, each 10 or 15 minutes. I have also caught some CW (Morse) activity. All this in the 2-m band, obviously.

why did you get the v3 model instead of the v4 ?

@tunedsignal 26 күн бұрын

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.

how does one creat a JSON file? interested in one for the Family Service and GMRS...I have all the freqs...just unsure of how to create an importable file to label them all at once

Thanks for reaching out. Its not straight forward.. I can tell you that!! You pretty much have to enter them manually in SDR++. There are several parameters for each entry; channel name, bandwidth, frequency and mode. How many frequencies do you want to at to the JSON? Tune into the signal

Did You Know : With Old Cat Wire You Can Make MultiResonant Band ANtenna? I Have One Long Wire ANtenna, BIts Something Stupid, I Cant Recall Over My head Now, But Its There,. Get It? :D Naah, It Was Like 30 Meters Long, Its Up In My Attic And My House Middle It Splitts Appart Into Dipole, One Side Goes To The Attic End And Ends There With Coil And Other Side Goes OUT The House And Down To The Fence , I Soldered The Copper Wire To The Fence And Put A Pully On The Whole Wire .. I Can Film It And Show How It Looks AND It Easily Picks Up 20 Meter Band, 40 Meter Band ANd Even 80M Band And All The AM Stations I Can Get Where I Am... In Attic i have THICK THICK Copper Wires, But Outside I Have One Strand Of Copper Wire, Not From Stranded Copper Wires, But A Thick One, But Not As Thick As Inside Of The House For Settle Effect, Btw I Get Florida Many Times At Contests, Like, A Lot of Times I get Florida :)

Use a 1:1 balun. A 9:1 balun is very much the wrong thing to use.

@tunedsignal 3 ай бұрын

Hello. You are very correct. I have recently tested with a 1:1 and there is a difference with lower frequencies. At 27 MHz.. the difference was not as apparent.

@johncrouch8988 Жыл бұрын

Forget the sdr, just buy a radio 📻, get set up and start talking! Not ham! That’s no fun. You find more ham users on 11m through the summer than on their frequencies. They should have to sit a test to go on 11m and pay for a licence. They don’t even know the 10 codes! Duh!😳

Having a radio is a great way to jump in and listen. I can't disagree. An SDR is a cheap way to step in the cb waters and learn a lot. What radio do you recommend for someone who is new to cb radio on a budget?
