friendly reminder to turn on captions y'all! P.S. Simon this is so fucking cool, do you think you'll ever get a transceiver to talk on radio too? I heard getting a license isn't actually that difficult
I can hear enthusiasm here. Welcome to short wave radio. I built a one valve radio kit aged 14. 2000 Ω headphones given by a neighbour, 90 Volt battery and a 3 Volt cycle lamp battery dropped to 2 with a resistor, a wire round the kitchen for an aerial and one onto the water pipe for an earth. A few squeals and whistles then a bird whistling followed by an announcement, "This is Radio South Africa." Wow. One valve. I listened to local amateurs on 160m, Top Band, and thought I'd like to do this one day. Got the G8JJC call aged 19, passed the Morse Code test two years later and got this one, G4GHB.
LOL! 😂Boy, do you have a LOT to learn!! And, I'm sure you will when you spend some time getting to the basics of signal types, radio propagation and band assignments. Your video took me back about 70 years when I got my first shortwave receiver for my eighth birthday (yeah, I'm OLD!) Like you, I was awed and amazed by all the different signals and stations "out there." I'm a long-time licensed ham, and still love the hobby. Keep listening and don't lose your enthusiasm - you're on the right track by having a ball and learning as you go. I'm subscribing to the channel so I can enjoy your progress along with you. Good luck Simon and keep up the good work.
Thank you for your comment and subscription! Yeah, I still have a LOT to learn but I'm excited. That's awesome that you got a start when you were eight!
"Eerie noise" at 8:48 is the FT8 digital mode on ham radio. Used on all the ham bands in specific segments. On 40 metres, it's on 7.074Mhz. Basically it's a computer mode. The ham radio op's computer generates a sound which is transmitted, and free popular software (WSJT-X or JTDX) can be used to decode FT8 signals from around the world and make contacts. BTW I'm a radio amateur from Ireland, call sign EI2KC.

I think this is great! I love it when the younger folks, like yourself, get bitten by the radio bug. I started out around 1980 as a teenager into shortwave radio. I got into ham radio shortly afterward ( where i could transmit - i got a license). I've never gotten tired of it. SDR's have brought a lot of good people into the hobby.

the music at 7:15 on AM broadcast band was bleed over from a local FM radio station. it is overloading the front end of your SDR and appearing in the AM segment. Applying amplification will only make it worse. Adding filters will help reduce adjacent interference.
I see what you mean because I've seen that before (way too many times). I actually didn't consider filters (thank you for the suggestion). But that one is an actual AM station in my area!
@@SimonVideoI believe somewere in L.A. there's a AM broadcast trans, that's AM stereo. A lot of the noise can also be the solar activity, next is tv signals and other RF signals
I love RTTY! Every Thursday night at 8:45-9:15 EDT people all over the country do a “Weekly RTTY Test” and we just try and make as many contacts as possible in half an hour. You can use free software (ie FLDigi) to send and receive RTTY signals, so if you want to hear more RTTY definitely tune in! And if you are a ham you can participate! It’s big nerd stuff but I love it
If you can afford it, get yourself a Hack One RF. It will blow your mind. Also, AM and FM are just the modulation types. They have nothing to do with the wave length. You can have 120M FM and 70cm AM and vice versa.

Love the video, brings back my first memories of hearing sw stations for the first time. Remember as a kid playing around with my dad’s old zenith trasocanic radio. It only did fm and am used to always wonder what was up with the weird distorted ssb transmissions. Eventually got an old sw radio from radioshack that did ssb and opened up a new realm. Got licensed as a ham in 04, and took a 10 year hiatus and the bug bit me again in 2014. Studied for the general license in 2014, passed it and have been at it hardcore since. I totally encourage you to study up and get your tech license, and if you also study the general question pool you may get both in the same day. 73’s and maybe I’ll hear you someday KC2MRW.

"I think I heard a W call sign meaning this is coming from the east coast?" W being east of the Mississippi and K being west is only in commercial stations. Hams are A/K/N/W and its the number that denotes where the station was first licensed. So in my case NI2O means that my callsign was first issued in the "2" region (NY/NJ). The class of license (Technician/General/Extra) can usually be determined by the length of the callsign. Longer is lower. So I am an Extra and have only a 4 character callsign. New hams usually get a 6 character callsign such as KC1ZZZ.
@@SimonVideoAmateur callsigns used to be geographically indicative of where one was in the country. This isn't really the case anymore. For instance, my first issued callsign was KB3OQM, which indicated that I was issued the callsign in the 3 call area (which covers Pennsylvania, Maryland, Delaware). If I moved elsewhere in the country, it was not necessary for me to get a new callsign that indicated where in the country I'd moved. My current callsign dates from when I lived in the zero call area, but I still retain that callsign now, long after I've moved from that part of the country. Think of it like phone number portability - you can have a phone number from a New Jersey area code, even though you move to California.
I've played around with these dongles when I first got into SDR but after a while because they were so flakey I upgraded to the SDRPlay RSP1A. Part of the problem I had with the dongle is with the antenna, neither the V dipole nor MLA 30 loop perform well with the dongle. I'd suggest spending the money on the RSP1A and a discone antenna instead. SDRUNO is a great product though the program for operating the SDR has a high learning curve it's worth the trouble and investment. The only thing good about the dongle package is the V dipole antenna which I use for recording NOAA weather satellite passes. The MLA-30 loop is my go-to antenna for SW listening.
Hi Simon, I just discovered your channel, it's amazing! I'm from northen Italy studiying Electrical Engineering and just did my ham radio license like 3 days ago, hope to see this channel grow :D
Welcome to the world of shortwave listening! You will find bunches of weird signals. Some of them will require decoding to get weather maps, satellite photos, etc. Dialing in the hams can also be challenging, as you found. It also depends on your software how hard it is to find the right mode. You'll get used to it and learn what a lot of them are.
@@SimonVideo I got into it while in college, back in the 1980s, took a few breaks, now I'm back with the SDRPlay (similar to your device) and having fun. There is SO much to hear.
Nice video! I bet you'll want to sign up for radio amateur course and get your licence pretty soon, listening is cool but getting on the air is a whole new level (also potentially expensive if you're not careful lol). I also have RTL-SDR and it works great, as someone already mentioned v4 is way better at getting lower frequencies, but this setup works well too. I also hear a lot of noise all over the bands as I'm in urban area and surrounded by residential buildings. With magloop antennas you can filter some of this out by rotating the antenna, try it out while listening and you'll figure it out. That is, if the noise is not from your power lines/computer, in that case buying a USB extension cable with ferrite cores might help. A lot of the people already explained what digital signals are (RTTY, FT8 etc.) - in general in ham bands you will find those on the lower part of the band, along with morse (CW), usually first 100khz or so, and the upper part is voice. Sideband voice is LSB under 10MHz and USB above, up to about 50MHZ where FM starts to take over (the 10MHZ band itself is digital/CW only, no voice). 40meters (7MHz) ham band goes up to 7.200 or 7.300 depending in what part of the world you are, that is why you were hearing ham conversations in what your software described as "shortwave broadcast". Also it was a contest, which you can figure out by people saying "CQ contest" and exchanging numbers. If there is no contest happening, you're much more likely to hear interesting conversations that go beyond just exchanging callsigns and signal reports. In general, lower frequencies are open and more active after sunset, due to ionspheric propagations. That's a rabbit hole in itself... There's a nice map at hf.dxview.org/ which you can use or just scroll around. If you can't hear anything locally, you can play with other people's receivers by googling web SDRs in different parts of the world. Another cool resource is sigidwiki.com, you can look up what different signals that you see in the waterfall may be. Best of luck and 73s !
The W/K rule is just for brocasters. Hams can have Calls starting with W or K anywhere. We aslo have calls starting in N or AA-AK. Also you might not have been able to hear the guy in japan, but the station you heard could.
I am 60 years old, and have been in radio for at least 30 years as a SWL, and I am still learning new things. I am glad that the younger generation is interested in radio. Yes, the loop antenna is a good antenna for the lower frequencies, I have been using a home made loop for many years and am very satisfied with it. good video, keep up the good work.🧐🤓
@@Redbelly357I'm interested in radio. My computer is my radio, and the SDR is what got me into radio to begin with. At some point I'll invest in a proper radio.
Hey Simon, this is a great video! I love the enthusiasm that comes through in your voice and that you're letting us join in your process of discovery. Keep it up! -- KF5ZKR.
Those weird sounds you hear are CW and RTTY signals that you can decode with another software wile you main software is running. It decodes the messages for you.
Those two stations playing David Bowie on the 40m (7mHz) band were probably just harmonics of some station near you, they sell filters that will block out AM/FM stations to avoid that if it bothers you too much
Buying the RTL Blog SDR induced me to learn more and I just got my first Ham radio licence. However, there's a huge difference in performance between the original RTL SDR dongle and clones. I would advise you to get the original v.4 and you won't even need the Ham it Up.
I just have a long wire stretched outside and coming inside with an Alligator clip to the radio antenna and I pickup a lot of clear stations late at night.
theres a v4 of the dongle that does some extra work on cleaning out the noise, and some extra features, with quality control on the end product same price roughly as well ✌
really cool video, you should do a video on quansheng with a good antenna im able to pick up conversations from america with a 5m piece of wire and im in europe
W0XD or something, for HAM callsigns, W K N A are all valid first letters for all of America, not necessarily East coast, however the zero means Midwest, but that’s not a hard fast rule, that person could have gotten their callsign in the Midwest then moved, or it could be a custom callsign
Hmmm, I'd just spend $120 and buy a SDRPlay RSP-1 which has everything needed to receive from well below the AM broadcast band to, I believe, 2 GHz. You will not be disappointed & by the time you buy the dongle & up converter you must be halfway to $120. As far as antennas a simple dipole works great. A dipole is just two wires where one is connected to the center conductor of the coax and the other to the shield. Once made it's stretched out like a clothes line with the coax dropping from the center of the pair of wires and wandering its way to the receiver. You do have to cut the wires the right length and there are online calculators for this but roughly 33 feet long for each leg is a 40 meter or 7 MHz dipole and it also works well on other intervals as well and will be heads above the rabbit ears that come with a dongle on any frequency below VHF. Don't get hung up on keeping a dipole in a straight line. Often people erect them in inverted V shapes as well as L shapes and even straight lines. Another antenna that works well and is simple is called the random wire antenna. I'd strongly suggest the dipole because an antenna works well when the impedance matching between receiver & antenna are ideal. When not it's like trying to start moving a stopped car while in 5th gear where none of the power is transferred to the wheels and the car stalls. The random wire antenna really needs a transformer in series with the wire to transform the high impedance antenna to the lower impedance of the receiver otherwise like the car little to no power is transferred. You can't miss with a dipole because inherently when cut to the right length they have nearly the impedance of the receiver thus all signals make it to the receiver. The random wire antenna requiring the transformer can be frustrating to one not familiar with antennas. Down the road you can build mag loop antennas & even beam antennas but for now I'd say make a simple dipole because rabbit ears are dead below roughly 145 MHz.
My first of your videos and i find you in sdr fun mode, don't forget that loop antenna are directionable and for find more station, change the direction of the loop, nord, south ,est west.... I'm a liistener too 🙂
If you're only receiving, all that's really necessary is to get a long length of wire outside, and if you have a choice, get it up as high as possible...the longer and higher, the better. Loop antennas like the one in the video are slightly directional.
You need to research a bit more about the ham bands and how to use SSB & CTTY. Also, the time of the year and the solar cycle affects the noise level tremendously.
Great video. I got hooked on ham or amateur radio after getting the same stuff you did. With the ham bands, you're going to use mainly USB or LSB. I have a Ham it Up and a Mag-loop. I still spend time using it with my RTL-SDR dongle. Of course, I got into ham radio and ended up getting my Tech, General and Extra Class license and now talk to people all over the world. It's great to watch someone discover the magic or coolness of radio. Thanks for the video and I look forward to more...73...Hugh...KN6KNB
Same here, @Hughpatterson1480. I got hooked just like him before I was licensed, during the lockdowns, and was listening to the local repeater weather nets during the great Texas Snowpocalypse. Ended up with my Extra class. 182 countries (dxcc entities) logged so far between voice & digital modes. High school friend 40+ years ago got me hooked, but life got in the way. Finally got licensed in 2021. @SimonVideo : just do it! You won't regret it! 73 K5MWA
@@SimonVideoGet a LNA and hook it up as far away from the rtl and ham as you can. I have a loop in my attic and the LNA is up there, too. Get your noise floor down. Cheers, brother!
Get a better sdr like sdrplay rsp1b. Is much much better than RTL SDR. ML30 + is good down till 2 mhz. After that is picking up only strong mw signals and is deaf after 500 khz.
Welcome to one of the most mysterious and interesting parts of the electromagnetic spectrum. The upconverter and RTL-SDR are *really* holding you back quite badly. They are total junk on HF with abysmal performance. Horrible spurs, intermod's, images, poor dynamic range, the list goes on. Get an AirSpy HF+ Discovery and really start receiving and enjoying what's out there.
the main reason for poor performance is local interference that your own equipment/appliances generate. you've already way overspent by purchasing the worst possible "inexpensive" garbage which works only 'on paper' but that's good, learning the hard way has its advantages. now concentrate on getting the antenna out the window or on a tree or roof hopefully this at least teaches you the scale of the amount of electromagnetic garbage your body has to cope with in your immediate sorroundings 24/7 even though your body's cells just like plants communicate using Non-transverse magneto dielectric means they are still affected by the components of the EM - the electric field and magnetic fields. That's why Maxwell originally wrote his equations in a notation encompassing Everything before the timid cut it down to only Half (vector calculus) hint hint

@SimonVideo it's a trap. Angry old men making CB sou d civilized. Glad you're enjoying the sdr. Do consider looking up a local HAM club and getting your license. It's a fun hobby with lots to do. Just got some pictures down from the space station from an SSTV event recently for the first time myself despite being licensed for a few years, was a thrill silly as it seems with youtube and whatnot. Anyway plenty of stuff to learn and radios to play with and even if you can't afford a fancy one right away most guys in a club would help you get a chance to try some neat kit out atleast.

Morse code and RTTY.
Nice video! I bet you'll want to sign up for radio amateur course and get your licence pretty soon, listening is cool but getting on the air is a whole new level (also potentially expensive if you're not careful lol).
I also have RTL-SDR and it works great, as someone already mentioned v4 is way better at getting lower frequencies, but this setup works well too. I also hear a lot of noise all over the bands as I'm in urban area and surrounded by residential buildings. With magloop antennas you can filter some of this out by rotating the antenna, try it out while listening and you'll figure it out. That is, if the noise is not from your power lines/computer, in that case buying a USB extension cable with ferrite cores might help.
A lot of the people already explained what digital signals are (RTTY, FT8 etc.) - in general in ham bands you will find those on the lower part of the band, along with morse (CW), usually first 100khz or so, and the upper part is voice. Sideband voice is LSB under 10MHz and USB above, up to about 50MHZ where FM starts to take over (the 10MHZ band itself is digital/CW only, no voice).
40meters (7MHz) ham band goes up to 7.200 or 7.300 depending in what part of the world you are, that is why you were hearing ham conversations in what your software described as "shortwave broadcast". Also it was a contest, which you can figure out by people saying "CQ contest" and exchanging numbers. If there is no contest happening, you're much more likely to hear interesting conversations that go beyond just exchanging callsigns and signal reports. In general, lower frequencies are open and more active after sunset, due to ionspheric propagations. That's a rabbit hole in itself... There's a nice map at hf.dxview.org/ which you can use or just scroll around. If you can't hear anything locally, you can play with other people's receivers by googling web SDRs in different parts of the world.
Another cool resource is sigidwiki.com, you can look up what different signals that you see in the waterfall may be.
Best of luck and 73s !
Make the next step: become a ham!
The W/K rule is just for brocasters. Hams can have Calls starting with W or K anywhere. We aslo have calls starting in N or AA-AK.
Also you might not have been able to hear the guy in japan, but the station you heard could.
7m signals are a part of the amatuer radio bands. FT8, RTTY, etc. Some 7M signals are AM signals, LSB, USB.
Welcome to radio spectrum rabbit hole. The RTL-SDR v3 has a bias tee. You can send power to the antenna with it, no need for external power.
Whaaaat?!
But that would be for a VHF/UHF amplifier, it wouldn't go through the upconverter.
I am 60 years old, and have been in radio for at least 30 years as a SWL, and I am still learning new things. I am glad that the younger generation is interested in radio. Yes, the loop antenna is a good antenna for the lower frequencies, I have been using a home made loop for many years and am very satisfied with it. good video, keep up the good work.🧐🤓
They not interested in radio. They're interested in computer. Radio is an afterthought.
That's awesome! Thank you!
@@Redbelly357I'm interested in radio. My computer is my radio, and the SDR is what got me into radio to begin with. At some point I'll invest in a proper radio.
I can pick up 1 shortwave station with the included antenna when you get the RTL-SDR. its out of eastern TN the call sign is WWCR.
Glad you enjoyed it ..Plenty of enthusiasm!!! Maybe get your licence and join in with these guys!
I think I'll have to!
WOW! This is FASCINATING! Hope some experts can chime in with suggestions?
Yeah, lots of people have given me advice and cleared up some stuff!
Hey Simon, this is a great video! I love the enthusiasm that comes through in your voice and that you're letting us join in your process of discovery. Keep it up! -- KF5ZKR.
Those weird sounds you hear are CW and RTTY signals that you can decode with another software wile you main software is running. It decodes the messages for you.
So much fun to see how excited you are about radio.
VK2ETI
What sdr app are you using? The bookmark feature is cool
Those two stations playing David Bowie on the 40m (7mHz) band were probably just harmonics of some station near you, they sell filters that will block out AM/FM stations to avoid that if it bothers you too much
Good to know
Not necessarily. They are smack in the middle of the 41m shortware broadcast band.
Buying the RTL Blog SDR induced me to learn more and I just got my first Ham radio licence. However, there's a huge difference in performance between the original RTL SDR dongle and clones. I would advise you to get the original v.4 and you won't even need the Ham it Up.
That's good to know! I don't think they had a V4 out when I got mine but maybe I'll pick one up.
Simon get your HAM license. It will open up a huge world of exploration into RF and electronics for you and the Technician class isn’t that difficult.
Yeah, I'm going to do that when I get a chance!
I just have a long wire stretched outside and coming inside with an Alligator clip to the radio antenna and I pickup a lot of clear stations late at night.
That's awesome!
theres a v4 of the dongle that does some extra work on cleaning out the noise, and some extra features, with quality control on the end product same price roughly as well ✌
What SDR software are you using?
This was SDR++ on Mac. I was using SDR# for a while but it's not cross platform sadly.
There is a newer RTL-SDR dongle in black case that covers the lower bands, KE9ANL
really cool video, you should do a video on quansheng with a good antenna im able to pick up conversations from america with a 5m piece of wire and im in europe
Really? Impressive
8:43 that is FT8 , it’s a Ham radio Digital mode.
W0XD or something, for HAM callsigns, W K N A are all valid first letters for all of America, not necessarily East coast, however the zero means Midwest, but that’s not a hard fast rule, that person could have gotten their callsign in the Midwest then moved, or it could be a custom callsign
Oh, okay! Thank you for clearing that up
The gurgling sound you couldn't understand sounds like Radio Teletype.
9:00 etc - that's RTTY, another radio protocol :)
Hmmm,
I'd just spend $120 and buy a SDRPlay RSP-1 which has everything needed to receive from well below the AM broadcast band to, I believe, 2 GHz. You will not be disappointed & by the time you buy the dongle & up converter you must be halfway to $120.
As far as antennas a simple dipole works great. A dipole is just two wires where one is connected to the center conductor of the coax and the other to the shield. Once made it's stretched out like a clothes line with the coax dropping from the center of the pair of wires and wandering its way to the receiver. You do have to cut the wires the right length and there are online calculators for this but roughly 33 feet long for each leg is a 40 meter or 7 MHz dipole and it also works well on other intervals as well and will be heads above the rabbit ears that come with a dongle on any frequency below VHF.
Don't get hung up on keeping a dipole in a straight line. Often people erect them in inverted V shapes as well as L shapes and even straight lines.
Another antenna that works well and is simple is called the random wire antenna. I'd strongly suggest the dipole because an antenna works well when the impedance matching between receiver & antenna are ideal. When not it's like trying to start moving a stopped car while in 5th gear where none of the power is transferred to the wheels and the car stalls. The random wire antenna really needs a transformer in series with the wire to transform the high impedance antenna to the lower impedance of the receiver otherwise like the car little to no power is transferred. You can't miss with a dipole because inherently when cut to the right length they have nearly the impedance of the receiver thus all signals make it to the receiver. The random wire antenna requiring the transformer can be frustrating to one not familiar with antennas.
Down the road you can build mag loop antennas & even beam antennas but for now I'd say make a simple dipole because rabbit ears are dead below roughly 145 MHz.
Look at rtl-sdr 88.108mhz bandstop and 2.6 mhz HPF filters will have cleanup some of the signals.
Good to know thank you!
My first of your videos and i find you in sdr fun mode, don't forget that loop antenna are directionable and for find more station, change the direction of the loop, nord, south ,est west.... I'm a liistener too 🙂
Thanks for the tip!
This is really cool. I wish I could do it without the giant ring antenna and pvc pipe. 😂
Exactly 😂
If you're only receiving, all that's really necessary is to get a long length of wire outside, and if you have a choice, get it up as high as possible...the longer and higher, the better.
Loop antennas like the one in the video are slightly directional.
@@N0LSDJust what I was coming to say, a long wire will work
There are plenty of free digital mode decoders out there, it will open up a new world to you. Lovely to hear your enthusiasm.
@ I will look into that. Thanks!
You’ve got the Radio Bug! 😊 have fun.
Haha thank you!
You need to research a bit more about the ham bands and how to use SSB & CTTY. Also, the time of the year and the solar cycle affects the noise level tremendously.
Oh really? Yeah I have a lot to learn
@@SimonVideo Google ionospheric propagation to start with.
Now imagine talking to other humans around the world with your own radio... go get your ham radio ticket ;) . I am learning for mine currently
Great video. I got hooked on ham or amateur radio after getting the same stuff you did. With the ham bands, you're going to use mainly USB or LSB. I have a Ham it Up and a Mag-loop. I still spend time using it with my RTL-SDR dongle. Of course, I got into ham radio and ended up getting my Tech, General and Extra Class license and now talk to people all over the world. It's great to watch someone discover the magic or coolness of radio. Thanks for the video and I look forward to more...73...Hugh...KN6KNB
Wow, that's awesome! I'm going to try and get my license soon.
Same here, @Hughpatterson1480. I got hooked just like him before I was licensed, during the lockdowns, and was listening to the local repeater weather nets during the great Texas Snowpocalypse. Ended up with my Extra class. 182 countries (dxcc entities) logged so far between voice & digital modes. High school friend 40+ years ago got me hooked, but life got in the way. Finally got licensed in 2021. @SimonVideo : just do it! You won't regret it! 73 K5MWA
You got a discord? it would be cool to share some radio info. My friend has a server as well dedicated to ham radio.
Introduce yourself to amateur (ham) radio. You'll love it. 👍
08:45 its the dongle itself bro
So, why still use the Ham it Up when you have a antenna for 1 to 30MHZ? Try the antenna without it.
It's because my SDR doesn't go that low, so it shifts everything up into the range my SDR can pick up.
It can sound like a party line! Normal.
Next up, Yagi :D
My poor wallet 😫
Have you ever tried CB?
I haven't!
The "low" frequencies are actually "High Frequency." 😂
Ha, that's true
the rtl-sdr v3 does way better with hf
Yeah that's why I got the upconverter
@@SimonVideoGet a LNA and hook it up as far away from the rtl and ham as you can. I have a loop in my attic and the LNA is up there, too. Get your noise floor down. Cheers, brother!
Enjoy listening Simon de ON3EE Eric from Belgium
Thank you!
You could have gotten the V4 and not needed the upconvert.
Get a better sdr like sdrplay rsp1b. Is much much better than RTL SDR. ML30 + is good down till 2 mhz. After that is picking up only strong mw signals and is deaf after 500 khz.
Good to know thank you!
Welcome to one of the most mysterious and interesting parts of the electromagnetic spectrum.
The upconverter and RTL-SDR are *really* holding you back quite badly. They are total junk on HF with abysmal performance. Horrible spurs, intermod's, images, poor dynamic range, the list goes on. Get an AirSpy HF+ Discovery and really start receiving and enjoying what's out there.
Thank you! Good to know. I'll have to upgrade
Buy a radio.
Preem vid
the main reason for poor performance is local interference that your own equipment/appliances generate.
you've already way overspent by purchasing the worst possible "inexpensive" garbage which works only 'on paper'
but that's good, learning the hard way has its advantages.
now concentrate on getting the antenna out the window or on a tree or roof
hopefully this at least teaches you the scale of the amount of electromagnetic garbage your body has to cope with in your immediate sorroundings 24/7
even though your body's cells just like plants communicate using Non-transverse magneto dielectric means they are still affected by the components of the EM - the electric field and magnetic fields.
That's why Maxwell originally wrote his equations in a notation encompassing Everything before the timid cut it down to only Half (vector calculus)
hint hint
Suggests putting a wire up in a tree. Doesn’t warn about lightning danger.
I think this guy’s approach is making a lot more safety sense than your skipping electrocution risk. The problem with lighting is you don’t know until too late.
@gen-amb bet you wear a helmet every time you go out...
First 🎉🎉
If you had a ham license or at least studied it, you would know that there are digital transmissions, including digital image transmissions.
At one point you didn't know these things. Im sure he is aware that learning more will teach him more. This comment is not adding anything helpful.
Dustin: It’s objectively commendable that this fellow is
a) exploring this technology in the way he is, and
b) producing this video and sharing it with anyone at all.
Your comment was what’s called a snipe. Why would you type in something like that and send it?
You don’t care about your suggestions to him; you just wanted another put-down notch for your belt.
But maybe I’m wrong in what I think of your comment. Maybe you were trying to share the textbook illustration of “sad ham” and your LARP was just that good.
@@gen-amb You are correct about the snipe. Not a way to be a mentor (elmer in ham jargon).
For a good laugh listen to 7.200 lower side band after the sun goes down
I'll try that out
@SimonVideo it's a trap. Angry old men making CB sou d civilized.
Glad you're enjoying the sdr. Do consider looking up a local HAM club and getting your license. It's a fun hobby with lots to do. Just got some pictures down from the space station from an SSTV event recently for the first time myself despite being licensed for a few years, was a thrill silly as it seems with youtube and whatnot. Anyway plenty of stuff to learn and radios to play with and even if you can't afford a fancy one right away most guys in a club would help you get a chance to try some neat kit out atleast.
