I agree with A for the cool factor but I think an F for assembly is a bit harsh considering that there is no printed circuit board. I would say a good C+ to B considering what it's made from. Cheers :)

@@inspiresoundpro Someone did a great job with the design and initiative. Can't take anything away for that. It's the solder and wax that gets the F. Just my opinion though At least he built one. I just watched. Still a good video.

@@Slugg-O Agreed especially about the wax but I have seen much worse soldering on CZcams so I still give it at least a C. :)

That depends on the laws of your country. Many of these low power devices fall into similar categories as FM devices they can buy such as car FM transmitters and mobile device transmitters. Each country has their own laws regarding this so I always try advise people to know the laws of their country first. I don't give legal advice and this is not legal advice. That is why there is a disclaimer both in the video and the description.

Thank you. I always enjoy it when people get value from my videos. I am working on putting together a complete training course for radio presenter which many of my viewers want but it does take a lot of time and work to complete.But hopefully it will be available eventually for new young presenters to use. There is so much radio broadcasting information that people just can't access because those who know it don't want so share it. I hope to change that. Thanks so much. I hope you do well with your broadcasting studies. Cheers :)

@@inspiresoundpro thank YOU 🙏🏾 this really helped with my projects i have to submit and i would love to be in your course as extra knowledge on top of my qualification

Yes this design has been around for ages. I built my first one back in the 1980's. Its such a great starter circuit that you can learn so much from. Not only do you get to learn basic electronics but you end up with a functional and totally fun transmitter that is just hours of pleasure to use. For the new radio presenters, as so many of my viewers are, this can be perfect for having their friends and family in their house listen to their first radio shows. I have built so many of these over the years that I don't know what I enjoy most, building it or playing with it. So much fun. I hope you decide to build another one again. Cheers :)

Thanks for your input on the cables. Always appreciated. I have had a few people talk about Lmr cables. They are great and solve a lot of problems. In many cases though the cost for small operators is not worth it. For a small community radio station simply turning up the transmitter power fixes any losses and the installation is simple enough with most setups being less than a thousand watts. Many as low as 100 watts. So they don't really see the value in it. On big professional set ups yeah its almost a no brainer. But for a station using a 250 watt transmitter into a two stack antenna set up 30 meters up needing only an erp of 200 watts its not even on their list to have LMR cables. But it's always good for new people to learn about the cable options. Cheers :)

Wow it's always great to hear about the big installations and to hear from broadcast industry professionals. So thanks for your input. I unfortunately never got work on such big set ups. It's even difficult to comprehend that kind of power and all the issues that go with it. In most of my set ups if it went wrong the transmitter would go into safe mode until you fix the problem with no real consequences but at your power levels it's a whole different ball game. The cost as well in a completely different league. I think the majority of my viewers will never encounter set ups like you have worked on so always interesting to get some input about it. Thanks for you nice compliment. I do try my best to make my videos as accurate as possible while making them as understandable for everyone as possible. The majority of my viewers are first timers so I try to make the information as accessible as possible. Thanks again for your input. Always appreciate getting feedback from professionals. Cheers :)

Yes I think the circuit was intending to show the negative voltage as a the earth or negative side and not minus 9V. I think this has more to do with that a 9V volt battery is used which would have a negative symbol but not actually mean a negative voltage because that would imply a 18V difference which this circuit probably cant handle. Thanks for pointing that out. Always helps to have extra eyes looking at it. Cheers. :)

This transmitter as it is now can have a longer and shorter range depending on whether it is used indoors or outside. Inside a house it will probably reach about 30 meters but outside can probably reach about 100 meters. If the antenna is changed it can probably reach up to one mile outdoors. I will have another video soon showing how to change the antenna to make this transmitter long range.

@@inspiresoundpro With higher wattage? How bout 15 watt?

This transmitter is a very low power transmitter of probably only 30 to 100 mw. A higher power transmitter with 1 Watt or more will have a much longer range but it still depends on the antenna height and type of antenna. Often the antenna height will make way more difference to the signal range than the signal power. Often the signal power only helps to fill in the signal area or footprint but the antenna height can make a huge difference. For example a 1 Watt transmitter at 20 Meters high will have a much much longer range than a 20 Watt transmitter at 1 Meter height. So although the power of the transmitter does have an impact on the range there are other things to keep in mind too.

You are very welcome :) Yes I have a video on how to tune antennas. My channel is mostly focused on transmitting but the same principles apply for receiving. Only problem is that to tune the antenna perfectly you actually need to run a transmitter into in to measure the return signal or you have to buy a fairly expensive antenna analyzer. The best option for receiver antenna is to simply adjust the antenna by physical length to as close to the signal wavelength as possible. The video to watch is this one : czcams.com/video/WOGX70-kIYA/video.html It is intended for transmitters so most of the tuning wont apply but it does explain how to calculate the antenna length using an online calculator.

Thank you. I always enjoy it when people get some value form my videos :) Yes this antenna can work very well for receiving. It may be an overkill if you only want a slight improvement but if you are far from a transmitter like in rural areas then this antenna is great for that. You can also build a directional version but that would be way bigger and difficult to install. For transmitting and receiving this antenna, especially if you tune it to the frequency you want, will give a very strong signal.

@@inspiresoundpro Thank you. I am going to ask a different question and didn’t want to bury it here. This way others can see it more easily and learn from your answer. Thank you!

Yeah I love building these little FM circuits. They actually sound pretty good too. I like this circuit a lot because it doesn't have a microphone connected like so many FM circuits on CZcams. That makes it more of a radio bug than a transmitter. With this circuit you can plug in your little studio and have lots of fun. Enjoy. Cheers :)

Well according to the terms and conditions of Udio, people who make music with Udio have commercial use of the music. What that means as far as selling a song is hard to say. There are still questions about the copyrights of AI created music. Many have said that according to laws being developed in USA Ai music cannot be copyrighted. This means although you might be able to for example use the music you create in your commercial projects according to Udio, there is still some confusion on what rights are actually given to the creator of the Ai music. This is not legal advice and because the views on Ai music are not clear its probably best to get legal advice about selling Ai music before you do.

@@inspiresoundpro it's going to be interesting to see this.. i write lyrics personally. Those are my lyrics... if i slap sound around them from this tool, do I not own my lyrics and song? ... its not a question meant to be answered, just a thought. Thanks!

I have other videos about transmitters and streaming radio .There are also some on how to be a presenter. Have a look in my channel.

I'm always happy to receive fair criticism. It does help to improve my videos. I'm not sure what you mean by saying that I didn't show the full screen and didn't show everything. Which part are you saying wasn't shown? I could help you with what you say wasn't shown.

Hi. Yes Station Playlist can work with this. I have used station playlists on a few of my radio stations and its great. RadioDJ is a great free alternative to Station Playlist but doesn't have all the features of Station Playlist. Basically any audio software that can give sound and any automation software can plug into this way of streaming. I know Station Playlist also has its own streaming plugin but to be honest I have only used Station Playlist in this way where I ran the audio out from the studio mixer into another PC which would run the audio streaming through WinAmp. I have another audio streaming video coming out soon that will not only give you the streaming that you can use on free platforms but will also show your listenership numbers. Most of the free streaming services ask at least for a small fee to see how many people are listening but this other way of streaming is rock solid and displays your listenership live as its happening at no cost. But to answer your question yes it works great with Station Playlist.

Thanks for that. Every trick we can try that helps get better results are very welcome. I have also found adding words like emotional or energetic also help. I think it will also change over time as Udio develops the app more but for now yeah I think experimentation is the way to go. Thanks for letting us know. I'm sure that will help people using Udio. Cheers :)

@inspiresoundpro Emotional words help shape song, I even tried putting a musical key prompt, G minor in this case to see what would happen, but my knowledge of the keys is too limited to know if that did anything.

That's a clever idea. I will give it a try. Yeah always worth experimenting to see if we can get better results. 😀

Studio equipment can range in price from just a few hundred dollars to many thousands of dollars. It depends on what quality you want and where you buy it from.

The price can vary from very cheap to expensive. There is no fixed price for transmitters. It depends where you buy it and what quality it is and power level output of the transmitters.

Hi. Thanks for your comment. Yes its true that it is commonly believed that a ballun is needed but in fact there are many engineers who believe that a balun is most likely to be done incorrectly and therefore would do more harm than good which is most likely when first time builders use one. The ballun can reduce some interference and match impedance but if the antenna is built correctly, tuned close to resonance, and installed correctly the ballan will most likely make no measurable difference to the transmitted signal. In two radio where the antenna is being used for transmitting and receiving then a ballun can be more noticeable but for a purely transmitting antenna which is what this design was intended for, a ballun is not really needed. I do appreciate your input though. Its always great to chat with people about this because it gives newcomers more insight into things they might not have heard of. And to add to this I ran a low power commercial radio station with a 1 Watt Fm transmitter and we did not use a ballun and the signal was fantastic. The reason is that the antenna was high up on a hill and tuned and installed very well. These things matter way more than a ballun. This is something I try to get my viewers to pay attention to more as it will dramatically affect their range. Thanks so much. Cheers.,

What is common to use a balance on HF frequencies, and VHF frequencies is not necessary, the dipole itself when Tim correctly should be almost a 50mm resistive load. So feeding it with a length of 50 ohm is perfectly acceptable. The phasing coax or power divider coax, it's usually made from 75 ohm, either rg11, or RG6 with Copper sheld, the point where the two interconnect, can be as simple as a basic coaxial t connector. Important part is to make sure that all of the coaxes are the same length. If one cable is even a few inches longer. It will cause the signals to not be in Phase when they leave the tower. You also have a high reflected power on your meter.

Thank you .Always great hear from people in the field. Yes as you said the idea of a ballun for all uses is not correct. In many cases the use of the ballun distracts people from paying attention to what you mentioned which can make a much bigger difference. Also I think some people think that the ballun fixes all problems which is not a good way to think. Thanks so much for your input. My viewers do seem to learn as much from the comments as the videos. Cheers :)

@allen_steel1236 ballun using not only to transform resistance. It is used as a bridge from an unbalanced coaxial cable and balanced dipole. If you connect them directly, there will be some standing waves on the body of the transmitter, and depending on how much power it can cause damage or errors on devices, connected to transmitter.

@@katushechnik Thank you. It's always great to add this kind of insight. It's the kind of thing new viewers enjoy seeing. Cheers.

Clever way to market your Spotify ;) But you are welcome to. Ai is amazing but will not be replacing anyone soon. It is great fun to work with and gives people an opportunity to create music without learning to write music and play an instrument. But it is not at the replacement stage.....yet lol. Many musicians are getting ahead of the game by using Ai for inspiration and even the basis for a new track. They then mix their own song from there. So as with all new tech, its not the Ai that will replace you but people who use AI the best way they can will maybe replace those who refuse to accept its existence. Things change and we need to adapt the best we can :) I do support original artists though so all the best with your music. I hope you have great success.

I have seen research being done on that. It is almost ready for that. So it wont be long and midi will become as common as the mp3 download. So hang in there it will come :)

You are very welcome. I'm glad you enjoyed the video. Always nice to see people getting value from my videos. Cheers

That's fair. Ai music isn't for everyone. It's still early stages and Ai music will keep improving. Of course original human made music is preferable but Ai music isn't going away and it does give people who don't have the music skills the chance to play and experiment with it. But I fully get the resistance to it. Cheers

I tried it and I must say that it can make very good songs. Better than all those trash made by 90% of the real musicians today.

@@alexyurk431 Yeah and it keeps getting better. Need to make a new video already for all the updates XD

@@alexyurk431 100% agree... and it only gets better overtime. Those that deny sound like Steve Balmer laughing at the iphone and how it won't work.

You are very welcome. I'm glad you enjoyed the video :)

Thanks for your comments. Yeah I normally would not recommend circular polarized antennas unless a very experienced and equipped person installs and maintains it. Circular can easily become a problem. If done properly circular polarized antennas can be great for built up areas and cities but other than that can be more of a problem than it's worth. Cheers.

Thank you. I'm glad you enjoyed the video :)

HI. Sorry I don't know that game.

Hi. Thank you for that. It's always great to have extra input from people in the industry with your level of expertise. The vast majority of my viewers are first timers so it might be a bit over some people's heads but always great to have some extra insight. Thank you.

If you mean you want to play the music from Spotify on your streaming station then absolutely not. You wil potentially be breaching both the user agreement of Spotify and possibly running into some serious copyright problems. This is not legal advice. I do not give legal advice but seriously don't do it. Get proper legal advice on this. Read the user agreement from Spotify and speak to a lawyer about copyright law. You could potentially be heading for some serious trouble. As I said this is not legal advice.

I unfortunately cant recommend any specific brands or models. Although I have tested some cheaper as well as broadcast level transmitters. I simply can't guarantee any brand or specific model. A rule of thumb for me is to see if the transmitter is either approved by FCC or of a quality that would be approved by the broadcast authority in your country. I don't recommend using any unlicensed transmitters. To work towards obtaining a broadcast license or operate within the law of allowed low power transmitters its always better to choose transmitters that are either approved or meet the specifications of approved transmitters in your country. Many of the transmitters will either have an FCC approved sticker on them or some sort of approval sticker from the broadcast authority of your country. Any other non approved or low spec transmitters are just a magnet for trouble. Make sure you know and abide by the laws of your country and only use approved equipment for your country. As I said in the video I don't condone any unlicensed broadcasting. Make sure if you want to broadcast that you are not breaking the laws of your country. Any broadcasting you chose to do is at your own risk and I do not recommend it or support any broadcasting that is not legally approved in your country or any other.

@@inspiresoundpro alright, i appreciate the advice.

@@cameronkemp9742I have a Retekess 15 watt that you can buy online for $100 with antenna

Hey that's great news. Well done. You are welcome to share a link to your new radio station here if you want. Keep it up. Best of luck with your station :)

@@inspiresoundpro Thanks !

You are very welcome. I'm glad you enjoyed it :)

Ah nice to know thanks. I did try a bunch of options and found that just setting the game overide to none did the trick but I'm sure there are many other ways to get around it.The problem is that there were next to no answers to this question on Google and Unreal Engine support and zero videos about it. So I figure this should help at least have an answer available to newcomers. Thanks for your comment. Always good to have feedback :)

You can make the wooden dowl stick longer but it will not change the strength because the strength comes from the bolts holding the aluminum rods to the box.

Thank you I'm glad you enjoyed the video :)

The idea behind the design is that it can be adapted to the parts available to you. A range of box, bolt and aluminum tubes can be used. The dimensions given are the ones that work well together but the dimensions can be adapted to your size box and aluminum rods. Some people have even adapted the design to other frequency bands like Vhf and uhf. The idea is not for it to be a one size only design but rather a template to adapt to what you have available. The wavelength for FM band though means keeping the lengths of the rods the same but most other things can change.

Please see the answer I gave you on other video

Please see answer I gave on other video

Hi sorry I can't give advice on equipment I don't know. The best is to check with sellers of any equipment.

Thank you. I'm glad you enjoyed the video.

Hey, remember that radio is one of the most difficult industries to get into. So don't be disheartened. Just keep sending demos out and keep calling stations to see if there is a gap. If all else fails and you have the money for it why not start your own online station? 😀

Hi. There is only one way really to protect your transmitter and that is with a lightening arrester which you place between your transmitter output and the antenna cable and then put a deep spike into the ground or attach to a water pipe that is earthed to the outside of the arrester. They are quite cheap and very easy to install. But buy the best one you can. Here are some links to ones on Ebay but you can buy them in many places. tinyurl.com/zh92tk45 or this one tinyurl.com/3tuu2jaf but make sure you choose one with the right connectors on it to fit with your cable connectors or you have to use adaptors that lose a bit of signal. Go to 7 minutes and 30 seconds 7:30 on this video of mine to see more about this czcams.com/video/mmGQQo2X1vY/video.html

Glad you enjoyed the video. Cheers

Hey thank you for the nice comments. Always nice to be appreciated thank you :) I'm glad you enjoyed the video. I try my best to make my videos have enough info to be worthwhile to watch but not too much to overwhelm people. I also try to focus on broadcast FM band because that's what most of my viewers want but I have heard of other people converting my stuff for other bands. In most cases it is just a change of measurements but, as you say, some things don't translate as well as that across different bands. Always fun to experiment anyway :) Nice to have you watching. ENJOY.

Lol well spotted! The Amplifier in this transmitter is no longer working. I just used it to show the inner workings of the transmitter. Most people would not notice the PA unplugged lol. This transmitter is running the 1 watt straight out of the main board. Had to mod a little bit to get it to run without the Amp.

Yes 1 watt can reach 7 miles quite easily depending on the antenna, the terrain and most importantly the height of the antenna. The receiver is also very important. If you use an old analog tuner then no you will probably just get a mile or two but a good quality digital tuner in a car can have you receiving the signal for many miles. I have run a 1 watt station that had listeners in their cars listening quite happily within a 7 mile radius.

@@inspiresoundpro i used to have 500watts in my orginal country Lebanon . Now I been in the US for 10 years and I really want to go back to radio scene but license is almost impossible. But i think I low power don’t require a license so probably couple of watts will do me good especially in Providence RI very small city and over populated.

In USA it is possible le to get low power licenses but it is apparently quite difficult to get one. Unfortunately as far as I know the FM signal not requiring a license is less than 100 mw and even worse the regulations limit the range so you have to use a transmitter with a small built in antenna. Not good enough for a radio station. You will only get about 100 yards or meters from it.

By GP do you mean a ground plane antenna? If so what type 1/4 wave or 5/8 etc?

Keep in mind that the radials are a quarter of a wavelength each. So if you were to make the spacing from center to center the two antennas would touch as they would be 2 X 1/4 wavelength = 1/2 wavelength. The spacing would also not make sense because the antennas would be completely out if phase. Another thing to consider is that with the two antennas touching there would be no space for adjustment to create down tilt.

@@inspiresoundpro thanks, makes sense :)

The wavelength distance is in between dipole radials, in between brackets the distance is 2,1m

Yes, the FM signal coming out of the antenna (depending on signal strength) which is set up correctly is most likely not going to heat you up enough to harm you purely with heat but is still very unhealthy. Extended exposure to high-power radio waves can cause all sorts of medical problems. I am not a doctor and don't give any medical advice so don't take this as medical advice or safety advice of any kind but from my experience most responsible broadcast companies will not allow anyone to be near a high-power signal for any length of time. In many broadcast installations, the entire broadcasting system needs to be shut down before anyone can even walk into the room where the equipment is stored. There may even be regulations in different countries that prohibit close contact with high-power transmitters when they are on, not to mention being anywhere near the antenna that is putting out any significant power. Working on an antenna that is "live" with RF power is also silly because if, for example, the cable is pulled out then the transmitter can be damaged because of the load being mismatched and if the person holding the end of that cable touches the core of that cable they could end up with some serious medical problems. Like I said, I am not a doctor and don't give medical advice, but I also would not advise people to be irresponsible.

@@inspiresoundpro I never said to touch an antenna that is live. Either way, those radio waves are not going to hurt you. Yes, if you are next to a high power millimeter wave antenna you could get some tissue damage because it can't dissipate the heat fast enough. But for FM down near the 100MHz range, you would need an awful lot of power... not something anyone making a DIY antenna is going to deal with. We have a 50kW output, in general radio waves are a form of non-ionizing radiation so all that happens is heat transfer. Nothing more, nothing less.

I didn't say that you said to touch the antenna. I was simply pointing out the dangers. As you mentioned, there are people who enjoy DIY projects, which I have on this channel. They are not always aware of potential dangers. The part in the video about being near the antenna when it is on is precautionary. It was not intended to be a scientific explanation of how radio waves affect people. I assumed that most people would understand that the cartoon character would also show that there was some exaggeration in expressing how dangerous it is while still suggesting that people be safe. I get your point about the level of power of radio signals needed to become a serious problem but the clip in the video was a simple short cautionary insert to make people aware of potential dangers and not to make a factual statement about the level of radio signals and their direct corollation with specific medical conditions. I'm not sure why you seem to take this so personally. It's a fun video filled with animation to introduce new people to tuning antennas and not a documentary. The video is far from being a scientific thesis and more a fun piece of edutainment. While I enjoy and appreciate input from so many people, I really did not intend to put out a controversial statement about any disputed scientific facts to start a battle of wills. If you see the video in the light of how it was intended you might understand that the argument is moot.
