Fm transmitter? - EVO 4G Q&A, Help & Troubleshooting

Is there ever a possibility of hacking the evo's fm radio to become an fm transmitter?
Sorry if this is duplicate, searched around and didn't see anything else on it.

I highly doubt it. Taking a screen and making it into a camera is pretty much what your asking. Maybe you can buy a portable FM transmitter and somehow cram it into a external case that sticks out similar to the 3500mah battery.

radio transmitters and receivers aren't fundamentally that different. It's likely possible, but you would need to write it into the kernel.

I would love to see this happen and show it off to a friend that works with the Civil Defense.

No can do. A radio receiver, and transmitter do contain some of the same circuitry but are arranged differently. No software can change that. Plus the phone is not FCC type accepted for transmitting on the FM broadcast band.

The phone has an FM Radio Transceiver capable of both broadcasting and receiving. I believe the major reason why we haven't seen a transmitter mode, even HTC, is due to FCC licensing. I'm not too savy on the FCC's world, but I would imagine that the EVO's transmitter would fall under the same low-power group as those little iPod and other PMP FM transmitters that just plug in to the headphone jack.
Might be something to bring up with Cyanogen and some of the kernel devs, after they get the FM receiver working.

I'd like to see this... Bring it up to cyanogen...

Ah, what exactly do you guys want to transmit? Signal wouldn't get very far...

We've been through this before.

Some of us have cars which are too old to have an Auxilary input, but too new to have a tape deck.

Ha! I read some other posts, and realized that it would definitely be a handy feature. I resigned myself to burning CD's from my music collection, as it got annoying to connect my iPod to an FM transmitter. Extra wires, chargers, and so on.
Well, hopefully someone figures it out. Probably kill the battery though.

I would suggest a hardwired FM modulator to add an aux port. My wife's 2004 Mitsubishi Endeavor didn't have one and the FM transmitters sounded crappy to me. Took me about an hour to hardwire a FM modulator in and now she essentially has an AUX port. It sounds much better than the transmitters since it's injecting it's FM frequency directly through your radio's antenna port.
Here's one pretty similar to what I installed - LINK
The drawback compared to a FM transmitter is that this is not portable.

Another possibility is to just purchase a new radio. Some car stereo's with aux inputs are cheaper than a new EVO.
I stopped using my FM transmitter with my iPod a long time ago because I hated the extra cables, and the transmission wasn't very good, though I tried several.

Is there some car audio manufacturer that actually makes nice stock-looking radios with features like BT, equalizer, and aux-in, without having to have 20 blinking LEDs or looking like it was part of a boombox from the 90s?

I dont think that you can do that with only the phone, as it has only fm receiver not transmitter. But you can do that by buying an fm transmitter accessory. Or get a car radio with bluetooth functionality.
sure he doesnt just use an fm transmitter that you plug into the headphone socket, you can get them for mp3`s,phones,etc and are usually rubbish quality.
Nokia N97 has a built in transmitter doesn't it? I know the Desire you would need to buy a seperate transmitter.
there are number of phones that have FM Transmitting, .. unfortunattly the Desire is not one of them.
You can buy an FM Modulator, this will go into the cigarette thingy in the car, and you can plug in it an iPod or phone or any other that has a decent wiring connection.
radio quality suck though
Nokia N900 has it built in as well.
htc hd2 and nexus one have fm transmitter hardware but not activated ,may be desire has it also
The Desire have the same chip as the Nexus One, but it has the FM receiver enabled out-of-the box.
It should be possible to enable the FM transmitter aswell, but it's all in the drivers.
how or who activates it?

same processor does not mean same wireless chip
The HTC desire is believed to include the Broadcom BCM4329 wireless chip. The specification of this does include an FM Transmitter. Whether or not this can be activated in software is a different matter!

AFAIK both the Nexus and the Desire uses the same wireless chip aswell, the BCM4329. I haven't seen a teardown of the Desire yet, so there might be some differences, but I do not see why.

A teardown won't really prove anything unless you also identified and catalogued every component, proving that none of them are capable of being an FM transmitter? If you have this evidence, please post links. I am already 99.9% certain that no HTC phone has one built in but I like to be 100% sure
Either way, FM transmitters suck. They have to have an extremely weak signal and the sound quality is appalling. If you can afford it, go and grab a head unit that supports bluetooth stereo (A2DP). An FM transmitetr will sot you half as much anyway,
Bluetooth sound quality is much better and depending on the head unit, you should be able to play/pause/skip/vol up/vol down using the controls on the head unit and it will probably also be able to display album/track info.

Huh, seems that my edit previously did not make it.
I haven't found a teardown yet, but it should pop up in the next few days as easter is over now.
Just to make myself clear, I do not know that the Desire and Nexus have the same wireless chip. It just would not make any sense at all if HTC were to change it when everything else is the same.
It would be amazing if the FM transmitter was enabled in the desire.
I hope it gets in with 2.2 or something...
any idea about FM transmitter on desire...
i think that as the hd2 and nexus they all have wifi n, fm transmitter and receiver...it's just the software that needs tweaking....i am no guru at linux and android so if anyone manage to enable them it would be awsome....although it would be battery drain to transmit yourmusic all the time

FM transmitter.

Hey guys, just wondering if anyone knows any good, cheap FM transmitters that would work for the HTC EVO. My car doesn't have blue tooth so I need to buy one of these! Obviously, the main reason I'm getting one of these is for music.
If anyone has one, tell me about it.
Thanks
Unless you live in the middle of nowhere, don't waste your money. I've tried a bunch and they are all terrible.
The only good ones are the ones that are hardwired to the antenna.
if you can find one, I bought one of the generic white ones that is similar to the tunecast 2. But it was made in china. I took it apart to do the antenna mod that you can do with the tunecast 2 and sure enough there was a pots inside. When i adjusted it I could pick really good. If you want something that will broadcast you can try the digital transfmitter from c crane. I have heard good things about it.
I have the Motorola t 505 Bluetooth fm transmitter. It's an ok fm transmitter. I wish it had a stronger fm signal... living in nyc, there aren't too many good empty stations to use..... another downside to the t 505 is the price.... I think its still a bit high.
What kind of car do you have, does it have the factory radio in it, if not what make and model stereo is in it?

+1 for the Moto T505. Perhaps due to the fact that my car's FM antenna is built into the rear defroster, my FM reception is typically quite poor with most FM transmitters. However, living in a much less urban area than NYC, I've no problem finding solid FM stations for the T505.

I just got this the other day on a recommendation and all I can is wow, it actually works. You won't be getting concert sound from it but if your deck has no tape/bluetooth/aux this is your best option. And if you don't like it Meritline is great with their returns

+1 here as well. I got the T505 in my car and it rocked - at first. The more and more I use it, the more and more I regret buying it. I'm saving money to buy a stereo deck with Bluetooth built in instead. I live in Chicagoland and even if I do find a clear station you can totally tell the audio quality isn't up to par. Do yourself a favor and get a deck with built in Bluetooth. You'll be much, much happier.
i actually bought the t505 a few weeks ago. posted a review on it here.
i live in NYC and it works great for me.
great buy imo, and if you order online its like 50-60.
i'm not trying to contest a deck with BT built in, i'm 100% sure that's better, but this works great for me and is dramatically cheaper.
imo, try to t505, if it doesnt work out, return it and save up for a good head unit with bt built in.

[Q] FM Transimitter

So...is the hardware in the G2 capable of supporting FM transmissions, negating the need for a third party piece of hardware to rock the **** out in your car?
Also, are there car stereos with bluetooth receivers? Just think, wireless Dead Kennedys...
I'm pretty sure its just FM reception.
Sent from my T-Mobile G2 running Cyanogenmod.
I have not read any consensus on the issue, but I have read that the hardware specs say that it is an FM transceiver, so it should be capable. I don't know if that is correct, but it has been posted on this forum.
No one, that I know of, has gotten it to work as a transmitter. It would be awesome.
Oh yes. It'd be great. Cause I don't have AUX port and using the cassette adapter really sucks (sound quality wise).

I hate CDs, especially in a car. I'll take a tape player any day. Sadly, all I have in my car is AM/FM. I might just get on down to a second hand store and buy a crappy stereo with an aux port.
You could buy a transmitter that plugs into the headphone jack. Nobody uses them much anymore so they're usually dirt cheap on eBay and they do the trick.

[Q] FM Transmitter for the Thunderbolt

Hi everyone, this is my first ever android device, loving it, especially with Car Home and navigation. I got a car kit (mount, charger etc) for my Thunderbolt and now the only thing left is getting a good FM Transmitter.
If you have any recommendations for an FM Transmitter to be used with the Thunderbolt, please reply here. Also if you do use one currently, let me know.
Thanks in advance
They are all pretty much the same. It's going over FM so sound quality won't be as good as it can be. Any ones that I used with past phones were the same quality (audio wise) whether it was a $10 ebay brand or a $50 Belkin.

Thanks everyone for the helpful tips + suggestions. I have decided from reading these replies that I'm going to hold off on getting an FM transmitter for now. I have a friend who is very good with cars and he told me he'd be able to install an aux input into my car for whatever the part costs me off ebay. I think I may just go with this option.

Going that way will get you much better audio quality than an FM transmitter will.
If you're stuck with using an FM transmitter, then the best one you can get is the Scoshe (I think that's how you spell it) *WIRED* FM transmitter from Wal-Mart. It runs off a 12v line (pull out your car stereo and cram or splice the wires into the 12v input and the ground), then it actually plugs into the back of your stereo, and your antenna plugs into the unit. When you flip the switch, it basically kills your antenna, so you can't get any interference at all. It is the absolute best FM transmitter you can get (as far as I'm concerned).
just get those mp3 player to tape-deck things, if you still have a tape deck in your car. it will be way better quality than FM transmitters.

I've seen these on crutchfield but I think if you're going to go through all the trouble why not just jut a new head unit in that has AUX? If you MUST go FM I'd do it this way but honestly it's as much work as a new head unit which would give you better sound quality than your stock stereo anyway.
Actually, I found the cheaper "ebay brands" to be better than the expensive brands. I had a run where I was buying new ones about every two months to use in my work cars, and the best ones were the ebay 7 dollar ones from Hong Kong. I have no verifiable proof of such, but this is my opinion which it seemed the OP asked for. Make sure you get one that has selectable bands though the entire fm range.

yep, which is almost pointless (for this topic) because aux ports are in a lot more head units than bluetooth
i was able to get away with a cheap one from walmart ~$20 and it worked great for me even used it on a trip that i was in the back and phone was 10-15 feet away from the antenna and i still had very little static.
Get a blackberry Bluetooth gateway. It plugs in to your aux port and connects to your device via Bluetooth. I use one with my stereo and used to use one in the car until I upgraded the car to a Bluetooth ready system. It will connect to any Bluetooth device that supports a2dp.

I went to Wal-Mart and in the Ipod/headphones section found a good FM transmitter by Griffin. It plugs into the cig port for power and then plugs into your phones Headphone jack. a little time playing with different stations and you can find one that works real good and is nice and clear.

I was actually thinking of buying this for myself, according to reviews it seem great
GOgroove Flexsmart X2 Advanced Wireless In-Car Bluetooth FM Transmitter with Charging, Music Control and Hands-Free Calling Capability for Android, iPhone, Blackberry and Windows Smartphones
I cant add the amazon link sadly since I dont have enough posts, but google
GOgroove Flexsmart X2 and you will find it.
this should be exactly what your looking for, its still a fm transmitter but besides bluetooth or aux you have no choice but to use fm transmitter, the reviews on that looks great (saw on amazon)
The best ones to get are the ones from crap storeslike big lots and etc. The cheaper the better for some reason. You have to remember that truck bridges and heavy metal objects will obstruct it. I personal have an M gear. For it from big lots for $4.99. But in the end they all suck.
I picked up a motorola roadster for a steal at a verizon store, was about 50 bucks there (they kind of screwed up a lot and tried to charge me about 300 dollars more on one bill, raised hell got credits for accesories) and the thing actually works pretty well. There are a few minor issues with it, but those are easily solved and the sound quality is actually surprisingly good over FM.
Now there is the problem with degradation of sound when broadcasted over bluetooth, then over FM, but unless you are an audiophile and have high end speakers in your car (and i'm assuming you aren't because you were asking for an fm transmitter) then I doubt you could really tell the difference.
Another handy dandy feature of this device is that it searches for OPEN fm channels so you aren't manually tuning one frequency by one and instead looking for a frequency you can actually break through.
http://www.amazon.com/Motorola-Road...7KOK/ref=sr_1_1?ie=UTF8&qid=1308640277&sr=8-1
The only problems I have with this unit is sometimes the BT disconnects for a second or so then it reconnects, but that only happens like once a week. Also sometimes coming out of sleep mode it won't kick on the FM transmitter. This is fixed by unplugging, turning off, waiting a few seconds then turning the device back on again. Other than that, this would seem to be the perfect solution to your problem.
I have also heard great things about the GOGroove Flexsmart X2, but have not tried it out so I cannot give an honest review of it.
Heres the link for that one: http://www.amazon.com/Transmitter-H...erry-Smartphones/dp/B003PPGOC0/ref=pd_sim_e_3
I tried the flexgroove it worked great with Bluetooth for the exception of no bass output. Speaking on it was not great but that's just my cars power outlet location making it to far for people to hear me. My brother got a jensen kit from amazon with steering wheel controls and separate lcd to see songs,calls and phone book that one worked great the Mic was external.

Cassette Option?
If your work car has a cassette tape, the best solution I have found is this:
http://www.bestbuy.com/site/Car-iPo...sette-Adapters/abcat0307013.c?id=abcat0307013
I don't remember which one I bought, but I got it at Wal-Mart a few years ago and it works perfect. You don't have to worry about traveling through areas where the FM stations change, and you don't lose any quality by transmitting over the FM signal.
