I have the CZE-7C fm transmitter and to past 500 feet from my house and clear audio once the top of the hill on my street there a lot of static on my handheld radio but was once i pulled the antenna there intermittent static this will get used on old Yamaha sterro that used to be downstairs that be used for when listening to music through speakers once some and them hooked I found that 87.9 and 87.7 work the best for me with no static
Update 2022. I got ahold of one of these to test only. I compared it to the C.Crane FM2R Transmitter. The range was better, good enough to cover a entire Church Parking Lot. At 100 millowatts, you Churches are fine to use this, but make sure you're not bothering a licensed broadcaster. Stay off of 88.7 and 87.9 Mhz, as it is not legal for any Part 15 FM Transmitter to be using, like 1710 is not legal for Part 15 AM Broadcasting. In a bigger, metropolitan city, this might not work for you because the FM Band is so crowded with Full Powered Stations, FM Translators and LPFM Stations that are Licensed. Another important piece of advice, when your Church Service is over, make sure to turn the transmitter OFF. Do not leave it on all week with a dead carrier. It is illegal for even licensed radio stations to be sitting there for hours with a dead carrier, and just because this is a small 100 millowatt signal that can't make it far out of the parking lot doesn't exclude any Churches, in otherwords, "Be Responsible".
As long as you don't give a reason for a random person actually going through and filing a complaint with the fcc, your golden. Your broadcasting the word of God.
These things have a whole lot of uses. And I was thinking about that because I've owned one of these little devices for about three or four years. And I've known people to have them since maybe like 2005. So I'm glad that these things are here because they have just so many functions you can use them for.
I run a pirate FM station and a local Baptist church heard about us and came to me to do the same for them !! was funny to show him our studio with the 100 watt transmitter and servers to store music and showed how we have a compressor to limit audio so we don't splatter he was impressed they just wanted parking lot coverage got a 15 watt one and made a 1/4 wave ground plane out of copper and PVC pipe they have a mixer for there music and there musicians it was a simple hook up set it on 1 watt works fine for them so now we are on the lords good side !!!

Former radio station owner here. I owned two AM's and one FM. All were licensed, commercial stations. You're playing with fire running a 100 watt unlicensed station. You might think you're not interfering with anyone, but there are ways you can easily interfere with other stations due to Intermediate Frequency relationships (look it up on Wiki). And, if the FCC does come knocking, they won't be smiling and definitely will not trifle with you. They'll shut you down, seize your equipment, and plop a heavy fine on you. My suggestion is that you operate within the law under Part-15 rules. I'm not trying to throw cold water on you, but I'd never want to see you on the wrong side of the FCC. They don't play!

Great test! I love the fact you've included the map of where you driving and where you started to lose signal. We've been doing the drive in thing for a few weeks, but haven't done a "range" test, although we do know that one of our members who lives a little under a mile away can still get the signal. It's amazing how sometimes the simple solution can work so well. We're just starting to plan to move back inside, but we'd like to keep the FM transmitter channel going, since there is still a segment of our people who *still* aren't hip to live-streaming (and have no interest in coming back in the building anytime soon, now that we are allowed to that) but they *will* come to the parking lot and listen from there. It's great to know what options/configuration we have to work with.
Why not try using a Audio Processor ahead of the FM Transmitter. Depending on what you can spend on a Audio Processor, the main thing to do is bring up is in the fringe part of the signal, the audio can be louder and more dominant circumference of the signal. That is what you want. I couldn't tell by the map how far the signal was going from the Church but since these are legal, I thought about buying one, but I want to test it first. I'm Retired and Disabled. I would like to test one first before a final purchase.
Great review dude! I'm not a big fan of intuitional religion but lookin to do Drive-in movies behind our auto shop that's in an industrial park. Thinking about evenings this spring. We got a huge 2 story blank white wall and a projector! Looks like this will work well, Thanks man! :)
Great video. Appreciate the review. I bought this unit. Plugged it in and all the electronics around it went crazy! Serious FM blocking and interference. Do you know why this is? Or how I can fix this? I’m trying to play sound over the radio from a projector for a drive in movie. Would love some help!
Avoid using your wireless devices near common sources of interference, such as power cables, microwave ovens, fluorescent lights, wireless video cameras, and cordless phones etc. Maybe this is why everything went crazy. Not sure but this can be the reason sometimes.
What can I do if we are setting up for both in the car and some folks in chairs? Is it possible to send the signal out to the transmitted and a pair of speakers for the folks in chairs?
Hi. The answer depends on the type of soundboard you use, and how sound gets out of it. If you have a basic “Passport” system with a main out and a monitor out, you hook up the main outs to your speakers (1/4 male to 1/4 male, speaker jacks are 1/4 female) and the monitor out to your FM transmitter. On my church’s portable board the monitor out is stereo RCA, so we would use stereo RCA male to 1/8 stereo male (into the FM transmitter female jack. If you’re livestreaming and you want to send clean audio to your camera or phone, you can use an iRig...but you’re going to need another out from your board to get to the FM transmitter. In that case I’d suggest a headphone distribution amp. Your main out (or your monitor out) is the input for the DA...your output options expand based on the number of outputs from your DA...2, 4, 8, whatever. Every DA I’ve seen has at least a 1/4 stereo input. The larger, rack mountable ones also have XLR inputs. Again it depends on the type of board that you have. Bottom line - whatever sends out sound, that’s what’s going into the FM transmitter.
Anything with an “audio out” can be hooked into the FM transmitter...as long as you have the right cable for it. Depends on the type of soundboard you have and what goes out...just the main out to speakers, or do you have aux sends? No matter where your starting point is, you need to end in a 1/8 stereo male going into the transmitter.
@@AJaytheCEO ok, I purchased one looks just like that one FCC regulated, but its 15watt good price from Amazon 129 can't believe the range 1 mile away from inside my house. Really enjoy the videos keep up the great work I always send people to your page from Facebook.
Hey! Great video, thank you for the great info! How would you recommend boosting the signal so the transmission could reach more isolated people in a rural community (Ireland)? Thanks!
Ignoring the legality - you generally need to buy a more powerful transmitter/look for an amplifier. But there are some practical ways you could extend the range. * Place it on a higher point where the signal could travel unconstructed (by trees, houses, hills etc) to the listeners houses. * Put a aluminum coca cola can to direct the signal in a specific direction
That antenna is tuned to 98.1 which would give the best coverage and less likely to pick XM radios. I get about 3-5 blocks with the transmitter 3ft off the ground inside a house surrounded by apartments and metal buildings; I have 5 of those transmitters.
hello, just got one of this devices to use it as a translation machine in side our church. but even though its a short distance, I can't get a clear sound. any thoughts on this?
Hello. Thank you for your review. We have a similar transmitter, might be a different brand. We use it for 'drive in' mass in our parking lot. We also have a channel splitter, so the Celebrant and the Deacon can each use wireless mics. We're having some static/interference issues. Based on your review, I think we can rule out the transmitter needing line of site, maybe the splitter does. Do you have any experience with using a splitter along with this type of transmitter? I know you hooked up yours inside the church. Any suggestions are welcome!
Splitter I take it’s a mixer ? Keep that and the transmitter away from each other low level can pick up all kinds of unwanted stuff and make sure you are not overdriving the audio that will cause distortion too if you have just that wireless mic system connected to the transmitter with out a mixer I do suggest buying a low dollar mixing board that way you can see if too much high level audio is going out.
Well that's not a legal transmit power out. Any audio heard more then 200 feet is a broadcast and requires a lic. However 87.9. Is not entirely an fm freq . 88.1 to 107.9. Is. Not all car radios will go below 88.1 . Fm. LP fm is 500milliwatts with matching antenna. LP fm is 700 mw and above. Use a better antenna but keep power low. Fcc isn't going to care about a weekly tx for 2 hours .
Probably not. I really need to take this video down as it was needed during the beginning of Covid but as many have noted some versions push the limits in range and power which can be illegal in the US and in some countries
The statement "check the FCC rules" leaves me cold. As an FCC licensed radio operator I find it hard to find a legal operation. See my other post. The FCC in the past at times has let thikngs go and then swooped down and picked off some examples.
I am a Former FCC Licensee of a 1,000 Watt AM Station. The former Administrations of George W. Bush, Barack Obama, Donald Trump, put the Commission in a mess. COVID has hurt Federal Agencies like the FCC financially. Now Joe Biden Administration will take the FCC in debt further, as the Washington D.C staff are still working from home, what's left of them, and field enforcement is at a minimum. Go do the math.
As long as you are within part 15. Which I believe is up to 100 milliwatts of output and have a antenna as shown here (right at the output of the transmitter) you should be fine. Seems like the range is within the bounds of the church, so I don’t expect much pushback from the locals. Even on 87mhz, it’s pretty sparse down there, and not competing with the big name license holders.
@@scottbailey1560 just look at the mess of the Digital TV channel repack. The FCC these days are more real estate agents for the radio spectrum, than enforcement agents. Selling off bands to the cell phone companies.
I bet you found the answer to this already, but if not, you can run an output from your sound board to the transmitter. That way everything running into the sound board can be output to the audio jack input on your transmitter.
Wrong, try again. These cheaply made products are made in China and they have absolutely no qualms with flat out lying and “certifying” anything and everything because there is practically no way any of them will ever be held responsible. Part 15 rules allow a maximum of 250uV measured at 3 meters from the transmitter. This can easily be achieved even with 100’ coax and a half watt transmitter. The transmitter in this video does 5 watts I believe, which means he IS interfering with licensed broadcasters. Remember, Jesus loves you even if sending the FCC to your church is his will. Amen.
Hey there one thing to mention when you're buying these transmitters some of them will say that they are in compliance with part 15 Ali FCC rules for unlicensed Broadcasting however you still need to be careful because some of these transmitters as I saw your video might exceed the radius of what is allowed which is 125 ft in which that pretty much covers the inside of a church one thing to note is that sometimes the signal made drift a little further than what it's supposed to especially if the conditions are just right. I'm considering on getting one of these transmitters for myself what I'd like to do is I want to set up an in-house broadcast here at my home so I can have music playing off of my computer and be able to just turn on any other radio in the house and listen to the music as supposed to wiring up my house for whole house audio which can be pretty expensive bluetooth speakers are great however it will only receive Bluetooth signals from a device that is synced up to it which in most cases you can only broadcast to one speaker. Thanks for the review.
I have a Weymic Professional Mixer | 7-Channel 2-Bus Mixer with a CZE-7C FM transmitter. How do I connect a microphone to the mixer so that when I am talking, I can hear myself on the radio? I am currently using my computer to play music and I was able to connect the transmitter and computer to play music. Music can be heard on the radio. The only problem I am having is connecting a microphone to the mixer so when I speak, I can hear myself on the radio. I have three Pyler dynamic wired microphones with the XLR hooked up to the microphone itself and a 1/4 inch jack on the other end. According to the picture of the mixer, the thin two way RCA to 1/8 inch cable is connected from one of the outputs jacks next to the mic inputs to the headphone jack on my computer. The fatter two way cable next to it is connected to the audio jack on the FM transmitter. If I use XLR to XLR cables for the mic input, what cables I need for the output so I can hear myself on the radio (I always have a radio nearby to test the connection)? Any assistance will be appreciated.
You only need to connect a line out from your mixer via xlr, 1/4 cable or rca to the 3.5mm input. Make sure you are using line in for a mix and the mic input for a mic only connection
This was posted to another site - but i want churches to be aware of the risks involved in this. The FCC part 15 does not apply to intended radiators, TRANSMITTER.. I purchased one of the transmitters you are showing about two months ago and have not powered it up pending a review by the FCC. I am a licensed Radio Operator Extra Class K3HQI. I doubt that the FCC will be taking enforcement activity but I am very familiar with FCC part 15 and there are two things not mentioned in this - most people are not aware that part 15 actually exists let alone its content. If I did operate the transmitter, i would cease and desist immediately if a complaint was recieved from ANYONE including a neighbor. No matter what, the rule for FCC part 15 is upon a complaint you IMMEDIATELY CEASE AND DESIST OPERATION OF THE DEVICE. Depending on the severity of the interference, the FCC, if they get involved, might take action from simply a nasty letter - usual if you promptly stop the action - and it may go to a fine, usually a minimum of $1,500 but can be much larger. I have seen %25,000. If you read Part 15 (it is available) in only one place does it mention intentional radiators, the term for a transmitter. Part 15 was intended to cover non-intentional radiators. That imeans every TV, Radio receiver, computer, coffee pot, microwave, any electronic device. They all radiate signals UNINTENTIONALLY, this is the rules for them, the reason for part 15. If my whatever device interferes with your licensed service, I must shut it down. It must comply with some standards. There is an eye of the needle that can be threaded by a camel but it applies to educational sites only, a church does not fit. Yes, you may have a k-12 school but if the transmitter is used for the service that will not pass muster. There are some licensed transmitters out there but they are 0.1 watt and have one 3 foot antenna that must not be modified. I have one, its antenna was "modified" because the tore. I think i could pass muster on it because I measured a like piece or wire, opened it and replaced it. They were designed to play a tape deck or MP3 through an FM radio very nearby. I looked at this for the church and discarded the idea. Its range is pitiful. Unfortunately the transmitter you (and I) have is 1 watt or 7 watts, well above the legal.limit and the antenna is not legal. In addition, and this is one of the most interesting items, they warn not to use without the antenna connected. GOOD ADVICE. A perfect antenna will show what is called an SWR oir 1:1. This would mean that all of the transmitter power is radiated. Any power that is not radiated is reflected back to the transmitter, is converted to heat and can burn out a critical item. A good antenna will show someting in the 1:1.1 to 1:1.8 range. Above 1:2 the transmitter starts to get at risk. I find it hard to believe the antenna connected directly to the transmitter will have a "ground plane", also called counterpoise, that will give this situaition. WIthout a counterpoise a one quarter wavve vertical (this antenna) has a very bad SWR - quarter wave for 93.5 MHz is about 31.5 inches I have a mag mount like the one you are using away from the transmitter and if it is not on a metal object (a car roof for example) it does not have the proper ground plane. I have in an emergency used a metal filing cabinet or a folder megal folding chair seat with it laying on the backs of two erect chairs. I would not operate any transmitter without the ground plane. If you have an amateur radio operator in your churches or a radio club in your area, they will likely have either an antenna analyzer, a nano VNA or an SWR meter that they can use to tell you if it is good. If you do not know how to contact one, i need only your approximate location (nearest town) and I can give you help to find one. These guys like to play with their toys! As I said, i am getting an FCC ruling. I want to use this as the weather gets better. The advertisments for this equipment ignore the negative parts of the law. What I am looking for from the FCC spectrum enforcement group is, will they allow it if there is no interference. There was a previous situation, not quite like this, that the FCC issued a wavier for - I am hoping they do in this case or tell us, as long as you do not interfere, OK..
The Enforcement Group? It's the head Commissioners to make the final decisions at the top. Those five Commissioners don't understand what you and I know. I know there have been people filing rule makings, but they haven't gone nowhere. You have big Corporations like iHeart, Cumulus, Beasley, Entercom, and smaller groups that will file against it, the NAB may fight it too. Trust me, I know you're a Ham, but I was a licensee to a 1 KW, AM Daytimer for 28 years. I know the some of the Hams in my area, my Consultant Engineer is a Ham. I should have gotten off my tail and got my Ham Ticket along time ago.
You're doing your audience a disservice by not warning them about how this device is NOT FCC COMPLIANT. According to the product page, this device has a half-watt (0.5 watt) output which will produce a field strength in excess of what is allowed under Part 15.239. In addition, besides not being FCC Part 15 certified it's also noted that operation on 87.9 MHz is not allowed with a compliant Part 15 FM transmitter. We've assisted businesses, hobbyists and educational institutions using legal, license-free FCC compliant Part 15 AM and FM transmitters. With the P.I.R.A.T.E. Act of 2020 using a transmitter like this can open both the property owner and the operator to a fine upwards of $2million dollars!
This is an old video and tons have already told me this information. During the time I was asked to test this out for churches that were looking for solutions at the height of COVID
@@AJaytheCEO That doesn't excuse not complying with FCC regulations. People will run across your video and think it's totally fine to use a non-compliant device, perhaps finding out the error of their ways when they end up on the wrong end of an FCC violation and potentially being liable for a very steep fine. You may have been asked to review the device but you glossed over the FCC regs, playing them off as not important. Tell that to the individuals or entities that get caught and fined. Tell that to the Eastside Free Methodist Church of Portland, Oregon or New Fellowship Baptist Church; Dorchester (Boston), Massachusetts or Omega Church International Ministries in Palm Beach, among others, who heard from the FCC due to non-compliant operation.
Wrong country. It’s the FCC here in the colonies. And they are more interested in selling off the radio spectrum to wireless carriers, than enforcing rules…

The short antenna on your FM transmitter will limit the range, try a higher frequency like 105 or 107 FM which will suit a shorter antenna.

Thanks. Glad it helped you
Hi. Is there any latency in the signal? Is the signal sent by the transmitter delayed compared to the direct signal from the computer?
Hi, any idea how to get rid of the static noise on these FM transmitters?
You need to change the channel to something different
can i use this as a in ear monitor system and does not worry about latency?
In theory you could but it would be one way. There shouldn't be any latency
So is that like a 3 mile radius?
I tested it at that distance but it did not work
What microphone do I use with this transmiitter? I know it needs a 3.5 mm plug, but which type of microphone.
I'm using the in house mixer so not a specific mic
What was the distance from your church when the signal cleared? I may have missed it. Thanks!!
It was about 1100 ft
How about the latency? Is there any latency?
there is no latency
Can people tune into a radio station on their cell phone with headsets rather than a car radio? I'm setting up screening. Are you on Facebook
I am not sure about this unless they are using an actual fm transmitter app on their phone, then it should work but I have never tested this.
Yes it will work as long as you have built in fm app on your phone ive tried this already some people use this as in ear monitors too
Does your fm transmitter give out an inference because I have been interferes with my dads headphones plus the subwoofer then the my harmony tv remote

I don't believe so but the church using this connected it to a PA. If there was a delay in sure they would have called me but I'll ask them
I'm also curious about the amount of delay between broadcast and reciever
Do you know how many cars can you have? doesn't matter ? it is just the dicttance?
There is no car limit, its just a distance thing similar to what you said.
Great video man and thanks for your help
That's a pretty modern church!
So it’s not necessary to hook it up to the main soundboard, it can work directly from the streaming computer ?
Anything with an “audio out” can be hooked into the FM transmitter...as long as you have the right cable for it. Depends on the type of soundboard you have and what goes out...just the main out to speakers, or do you have aux sends?
No matter where your starting point is, you need to end in a 1/8 stereo male going into the transmitter.
can we receive it through mobile (FM)???
If the app used in your phone is tapping into actual radio waves then yes it will
Do you know if doing an actual movie will cause latency issues with the audio?
No it won't
You have EV Speakers in your church ?
Yes
these work better with a grounded power supply
how much power does it have?
What do you mean by power? Range or how much it draws from the wall?
@@AJaytheCEO How many watts of power does it produce?
How many meters or km was the range?
How many watts is that unit looks just like the one I received.
Don't remember gave it to client about a month ago now
@@AJaytheCEO ok, I purchased one looks just like that one FCC regulated, but its 15watt good price from Amazon 129 can't believe the range 1 mile away from inside my house. Really enjoy the videos keep up the great work I always send people to your page from Facebook.
100mw/500mw
Hey! Great video, thank you for the great info! How would you recommend boosting the signal so the transmission could reach more isolated people in a rural community (Ireland)? Thanks!
Honestly, I am not sure as this is not allowed without a radio license in the US so I am not sure about regulations in Ireland.
Ignoring the legality - you generally need to buy a more powerful transmitter/look for an amplifier.
But there are some practical ways you could extend the range.
* Place it on a higher point where the signal could travel unconstructed (by trees, houses, hills etc) to the listeners houses.
* Put a aluminum coca cola can to direct the signal in a specific direction
About How Many Miles Is That Away From The Church, The Range Of It ? Thanks...
I tested it over 10 miles but it only worked at about 500 ft from the source
That antenna is tuned to 98.1 which would give the best coverage and less likely to pick XM radios. I get about 3-5 blocks with the transmitter 3ft off the ground inside a house surrounded by apartments and metal buildings; I have 5 of those transmitters.
hello, just got one of this devices to use it as a translation machine in side our church. but even though its a short distance, I can't get a clear sound. any thoughts on this?
Verify a signal is actually going to the device and then try different channels. If you are still having issues change the input jack and try again.
Great video. Would love to get your opinion on equipment for pop up drive in movie?
Email me Questions@ajayholmes.com
Hello. Thank you for your review. We have a similar transmitter, might be a different brand. We use it for 'drive in' mass in our parking lot. We also have a channel splitter, so the Celebrant and the Deacon can each use wireless mics. We're having some static/interference issues. Based on your review, I think we can rule out the transmitter needing line of site, maybe the splitter does. Do you have any experience with using a splitter along with this type of transmitter? I know you hooked up yours inside the church. Any suggestions are welcome!
Splitter I take it’s a mixer ? Keep that and the transmitter away from each other low level can pick up all kinds of unwanted stuff and make sure you are not overdriving the audio that will cause distortion too if you have just that wireless mic system connected to the transmitter with out a mixer I do suggest buying a low dollar mixing board that way you can see if too much high level audio is going out.
What on earth is a celebrant? What kind of heresy is that?
Well that's not a legal transmit power out. Any audio heard more then 200 feet is a broadcast and requires a lic. However 87.9. Is not entirely an fm freq . 88.1 to 107.9. Is. Not all car radios will go below 88.1 . Fm. LP fm is 500milliwatts with matching antenna. LP fm is 700 mw and above. Use a better antenna but keep power low. Fcc isn't going to care about a weekly tx for 2 hours .
I'm pretty sure that's not legal in Germany
Probably not. I really need to take this video down as it was needed during the beginning of Covid but as many have noted some versions push the limits in range and power which can be illegal in the US and in some countries
It appears that the link is dead do you know where I can get this
Use this: amzn.to/3la762Q
that was awesome
Thanks
I really impressed brother . How to get this . Amazing ❤
The statement "check the FCC rules" leaves me cold. As an FCC licensed radio operator I find it hard to find a legal operation. See my other post. The FCC in the past at times has let thikngs go and then swooped down and picked off some examples.
I am a Former FCC Licensee of a 1,000 Watt AM Station. The former Administrations of George W. Bush, Barack Obama, Donald Trump, put the Commission in a mess. COVID has hurt Federal Agencies like the FCC financially. Now Joe Biden Administration will take the FCC in debt further, as the Washington D.C staff are still working from home, what's left of them, and field enforcement is at a minimum. Go do the math.
As long as you are within part 15. Which I believe is up to 100 milliwatts of output and have a antenna as shown here (right at the output of the transmitter) you should be fine. Seems like the range is within the bounds of the church, so I don’t expect much pushback from the locals. Even on 87mhz, it’s pretty sparse down there, and not competing with the big name license holders.
@@scottbailey1560 just look at the mess of the Digital TV channel repack. The FCC these days are more real estate agents for the radio spectrum, than enforcement agents. Selling off bands to the cell phone companies.
How can I run it through the church soundboard?
I bet you found the answer to this already, but if not, you can run an output from your sound board to the transmitter. That way everything running into the sound board can be output to the audio jack input on your transmitter.
What type of microphone do you use with this system?
Any type would work minus a mic needing phantom power
@@AJaytheCEO Not true, many mics will not work with this transmitter.
great test
On April Fool's Day put up parking meters .
The Lord loves a sense of humor.
Ajay what type of antenna you are using?
It's a rubber duckie when using it; keep the power on low!
You Rock! Thank you!
. woow nice content . i am baptist alson here in philippines
Thanks
Can you give me this transmitter? If you don't need it anymore, I will pay some of its cost too.
I do not have this anymore as it was for a church which is still using it
1 mile i have one
Hey jay don't worry about FCC with that device. It has the FCC part 15 ID on it your allowed to use such a device without licensing. Your good
Awesome thank you for the confirmation
Wrong, try again. These cheaply made products are made in China and they have absolutely no qualms with flat out lying and “certifying” anything and everything because there is practically no way any of them will ever be held responsible.
Part 15 rules allow a maximum of 250uV measured at 3 meters from the transmitter. This can easily be achieved even with 100’ coax and a half watt transmitter. The transmitter in this video does 5 watts I believe, which means he IS interfering with licensed broadcasters.
Remember, Jesus loves you even if sending the FCC to your church is his will. Amen.
Hi - what software did you use to make your intro video?
Love your videos.....
After Effects template from Videohive.net
@@AJaytheCEO Thank you! I really liked it.
That is awesome and you're spreading the gospel ❤
Hey there one thing to mention when you're buying these transmitters some of them will say that they are in compliance with part 15 Ali FCC rules for unlicensed Broadcasting however you still need to be careful because some of these transmitters as I saw your video might exceed the radius of what is allowed which is 125 ft in which that pretty much covers the inside of a church one thing to note is that sometimes the signal made drift a little further than what it's supposed to especially if the conditions are just right. I'm considering on getting one of these transmitters for myself what I'd like to do is I want to set up an in-house broadcast here at my home so I can have music playing off of my computer and be able to just turn on any other radio in the house and listen to the music as supposed to wiring up my house for whole house audio which can be pretty expensive bluetooth speakers are great however it will only receive Bluetooth signals from a device that is synced up to it which in most cases you can only broadcast to one speaker. Thanks for the review.

Can u send me this item
No
I have a Weymic Professional Mixer | 7-Channel 2-Bus Mixer with a CZE-7C FM transmitter. How do I connect a microphone to the mixer so that when I am talking, I can hear myself on the radio?
I am currently using my computer to play music and I was able to connect the transmitter and computer to play music. Music can be heard on the radio.
The only problem I am having is connecting a microphone to the mixer so when I speak, I can hear myself on the radio. I have three Pyler dynamic wired microphones with the XLR hooked up to the microphone itself and a 1/4 inch jack on the other end.
According to the picture of the mixer, the thin two way RCA to 1/8 inch cable is connected from one of the outputs jacks next to the mic inputs to the headphone jack on my computer. The fatter two way cable next to it is connected to the audio jack on the FM transmitter.
If I use XLR to XLR cables for the mic input, what cables I need for the output so I can hear myself on the radio (I always have a radio nearby to test the connection)?
Any assistance will be appreciated.
You only need to connect a line out from your mixer via xlr, 1/4 cable or rca to the 3.5mm input. Make sure you are using line in for a mix and the mic input for a mic only connection
Unless it is FCC part 15, it will be illegal to use in the US. People can get away with it until the first complaint...
you cannot use this in the uk thay will do you
This was posted to another site - but i want churches to be aware of the risks involved in this. The FCC part 15 does not apply to intended radiators, TRANSMITTER..
I purchased one of the transmitters you are showing about two months ago and have not powered it up pending a review by the FCC. I am a licensed Radio Operator Extra Class K3HQI. I doubt that the FCC will be taking enforcement activity but I am very familiar with FCC part 15 and there are two things not mentioned in this - most people are not aware that part 15 actually exists let alone its content.
If I did operate the transmitter, i would cease and desist immediately if a complaint was recieved from ANYONE including a neighbor. No matter what, the rule for FCC part 15 is upon a complaint you IMMEDIATELY CEASE AND DESIST OPERATION OF THE DEVICE. Depending on the severity of the interference, the FCC, if they get involved, might take action from simply a nasty letter - usual if you promptly stop the action - and it may go to a fine, usually a minimum of $1,500 but can be much larger. I have seen %25,000.
If you read Part 15 (it is available) in only one place does it mention intentional radiators, the term for a transmitter. Part 15 was intended to cover non-intentional radiators. That imeans every TV, Radio receiver, computer, coffee pot, microwave, any electronic device. They all radiate signals UNINTENTIONALLY, this is the rules for them, the reason for part 15. If my whatever device interferes with your licensed service, I must shut it down. It must comply with some standards.
There is an eye of the needle that can be threaded by a camel but it applies to educational sites only, a church does not fit. Yes, you may have a k-12 school but if the transmitter is used for the service that will not pass muster.
There are some licensed transmitters out there but they are 0.1 watt and have one 3 foot antenna that must not be modified. I have one, its antenna was "modified" because the tore. I think i could pass muster on it because I measured a like piece or wire, opened it and replaced it. They were designed to play a tape deck or MP3 through an FM radio very nearby. I looked at this for the church and discarded the idea. Its range is pitiful.
Unfortunately the transmitter you (and I) have is 1 watt or 7 watts, well above the legal.limit and the antenna is not legal.
In addition, and this is one of the most interesting items, they warn not to use without the antenna connected. GOOD ADVICE. A perfect antenna will show what is called an SWR oir 1:1. This would mean that all of the transmitter power is radiated. Any power that is not radiated is reflected back to the transmitter, is converted to heat and can burn out a critical item. A good antenna will show someting in the 1:1.1 to 1:1.8 range. Above 1:2 the transmitter starts to get at risk. I find it hard to believe the antenna connected directly to the transmitter will have a "ground plane", also called counterpoise, that will give this situaition. WIthout a counterpoise a one quarter wavve vertical (this antenna) has a very bad SWR - quarter wave for 93.5 MHz is about 31.5 inches I have a mag mount like the one you are using away from the transmitter and if it is not on a metal object (a car roof for example) it does not have the proper ground plane. I have in an emergency used a metal filing cabinet or a folder megal folding chair seat with it laying on the backs of two erect chairs. I would not operate any transmitter without the ground plane. If you have an amateur radio operator in your churches or a radio club in your area, they will likely have either an antenna analyzer, a nano VNA or an SWR meter that they can use to tell you if it is good. If you do not know how to contact one, i need only your approximate location (nearest town) and I can give you help to find one. These guys like to play with their toys!
As I said, i am getting an FCC ruling. I want to use this as the weather gets better. The advertisments for this equipment ignore the negative parts of the law. What I am looking for from the FCC spectrum enforcement group is, will they allow it if there is no interference. There was a previous situation, not quite like this, that the FCC issued a wavier for - I am hoping they do in this case or tell us, as long as you do not interfere, OK..
The Enforcement Group? It's the head Commissioners to make the final decisions at the top. Those five Commissioners don't understand what you and I know. I know there have been people filing rule makings, but they haven't gone nowhere. You have big Corporations like iHeart, Cumulus, Beasley, Entercom, and smaller groups that will file against it, the NAB may fight it too. Trust me, I know you're a Ham, but I was a licensee to a 1 KW, AM Daytimer for 28 years. I know the some of the Hams in my area, my Consultant Engineer is a Ham. I should have gotten off my tail and got my Ham Ticket along time ago.
Grab it slap a lot bigger antenna on it botta boom pirate radio!
You're doing your audience a disservice by not warning them about how this device is NOT FCC COMPLIANT. According to the product page, this device has a half-watt (0.5 watt) output which will produce a field strength in excess of what is allowed under Part 15.239. In addition, besides not being FCC Part 15 certified it's also noted that operation on 87.9 MHz is not allowed with a compliant Part 15 FM transmitter. We've assisted businesses, hobbyists and educational institutions using legal, license-free FCC compliant Part 15 AM and FM transmitters. With the P.I.R.A.T.E. Act of 2020 using a transmitter like this can open both the property owner and the operator to a fine upwards of $2million dollars!
This is an old video and tons have already told me this information. During the time I was asked to test this out for churches that were looking for solutions at the height of COVID
@@AJaytheCEO That doesn't excuse not complying with FCC regulations. People will run across your video and think it's totally fine to use a non-compliant device, perhaps finding out the error of their ways when they end up on the wrong end of an FCC violation and potentially being liable for a very steep fine. You may have been asked to review the device but you glossed over the FCC regs, playing them off as not important. Tell that to the individuals or entities that get caught and fined. Tell that to the Eastside Free Methodist Church of Portland, Oregon or New Fellowship Baptist Church; Dorchester (Boston), Massachusetts or Omega Church International Ministries in Palm Beach, among others, who heard from the FCC due to non-compliant operation.
STOP SAYING "SO"!!!!!!!!!!!!!!!!!!!!!!!!!!!
Chinese sprog box do not use these units ever they cause untold damage to the spectrum
offcom
Wrong country. It’s the FCC here in the colonies. And they are more interested in selling off the radio spectrum to wireless carriers, than enforcing rules…
