My buddies Captivate, which is still running a 2.2 I9000 rom, kernel, and modem is getting engine interference from our work truck when he makes or receives a call and it makes him sound a lot like a robot. I have flashed multiple modems on the phone without any success. The interference gets worse as the engine revs up and goes away completely when idling. My Captivate never did this, nor does my Atrix. Is this a hardware problem or something I maybe able to fix with another modem?

Alright guys, here's my problem:
When I first got my phone, I had excellent cell reception and all my calling features worked, i.e. bluetooth calling in particular. But this was on JF6/JH7 STOCK.
I will not go back to stock, I just love my custom ROM too much. But the problem I have is that I've lost my bluetooth usability and my cell reception is questionable at best sometimes. I live in Maryland, and it's now a law that we can't use cell phones at all while we're driving unless we use it handsfree.
I've tried a slew of combinations including Speedmod and Firebird2 with at least 4 different modems including JK3, JK4, JL2, and JL3.
So here's my question to you all:
With your custom kernel/modem selection, do you have usable bluetooth WITH good cell reception? And if you happen to have a FORD vehicle with SYNC in it, does your setup work clearly with it? (Even though I'd imagine it to be the same with Honda/Acura/Nissan/etc...)
Please include your setup in your post!
Long island ny, in know that is not your area, but speed mod, dill pickle, firebird, ursa minor, sucker punch, paragon kernels with jk3, jk4, jl2, npk1 modems all work with my ford sync fine.
Current set up is
Paragon rom
Dill pickle kernel
Jk4 modem
In PA running Serendipity 5.10, Suckerpunch #50 and JK4. Sync also works great in my car and cell reception is also good.
Has anyone tried the other modems to work with the stock froyo to see if they work better?
Not tried any myself since flashing KB1, but when on JJ4, trying any non AT&T Froyo modem.bin would result in a loss of sound during voice calls. HSUPA however would work under such a condition. Too bad I need this device to work as a phone first. To get a non AT&T modem, you needed to go with a non AT&T kernel, and then bluetooth voice would be static, so you also need a non AT&T framework. With a native ROM, you are pretty much HSDPA only, unless someone figures out how to patch in necessary code to enable the required handshaking.
I tried some other modems, but none had working sound in phone calls. You might be able to get vibrant modems to work, but then you'd lose 3g
When I was first working on HSUPA for the Captivate, I found that no alternate modem worked properly on the Captivate software. I believe this is due to the code being "wired up" a little differently. Every alternate modem lacked sound in phone calls and the only way around this was to use an I9000 (or Vibrant, etc) ROM with a matching modem. I think everyone stopped trying to find out exactly why the other modems don't work with Captivate ROMs once it reoriented kernels solved any issues we had with running I9000 ROMs on the Captivate. It was just a lot easier to use an I9000 ROM with an I9000 modem.
What we need is some kind of spreadsheet with ROMs down the side and modems across the top, and 3 different symbols representing Data, Voice, and GPS. You would colour each one RED, YELLOW or GREEN depending on how well it performed at that task on a given ROM.
Hi, i'm using the latest firmware for the TPH product code (PDA:JP5,MODEM JPY).
When i turn on the wireless and listen to music i notice there's some background noise, with the wireless off the sound quality is great.
This didn't happend with my stock firmware from my operator.
Is there a bug with JP5 Firmware or JPY modem?
Thanks in advance!
I had this problem using the 2.2.1 JPY modem. So I imagine that to be the cause. I never ran JP5 Rom.
Do you get pops and clicks?
Yup that's exactly the problem i face BUT only when the wireless is on.
Yup, I found that out by luck.
My theory is they made the wireless radio stronger in JPY, and as a side effect, caused a bit of interference.
Some people love the JPY modem, but I listen to lots of music so the modem had to go. Problem cleared up after a modem change.
ZSJPG is a pretty solid modem if you're looking for alternatives.
It seems we're in the same field, i listen to a lot of music on my phone.
Mixing modem's and pda's doesn't cause any stability problems?
I haven't noticed any.
For instance, I'm running JVB 2.3.3 rom, paired with a 2.2.1 ZSJPG modem.
Things are stable. I'm not dropping any calls or anything like that. The phone is still running normally in all other areas.
Here's a ZSJPG modem you can flash with Odin if you are interested.

Thank you very much!I'll try it out.
Hello All,
Have just started using this forum and failed to introduce myself previously, my name is Jay; I am 27 from DC but in Afghanistan for a few more months (yea..sucks) new to rooting, flashing and all that but I have recent interest in it and it passes the time better than most thing we are "allowed" to do over here.
I just switched from a HTC Desire to a Galaxy Captivate
So far...I have unlocked it (via cellunlocker.net), upgraded to the leaked 2.3.4 Gingerbread, Rooted using the 10step method posted here, Installed Victory v1.5 Rom, tried flashing Talon kernel but bricked the phone and had to redo the above...
My question is to those more knowledgeable than myself with all this...what is the best Kernel, Rom, Modem...whatever else...that I can have on this device to keep it running smoothly, fast and reliable?
I do all the basic call, txt, surf...play games, watch movies, use apps, etc...not a developer but want my phone to be tweaked as much as possible so it does not seem outdated or lag with new things being added.
My current settings are:
Baseband I897UCKH3
Firmware 2.3.4
Kernel 2.6.35.7-I897UCKH3-CL461307
Build VictoryRom_v1.5
There is nothing wrong with the phone...as I said above, if I could do more to it and have an overall better device and pass some time here I would enjoy that. Victory seems great but all I notice myself is the battery indicator has changed and...thats about it (a lot likely goes unnoticed by me)
I do have one problem with the phone that maybe a different modem can fix? (I hope) for some reason my GPRS will not work out here with my browser...I can use the market and apps that connect to the internet but my browser seems to be WiFi only. I have changed the settings from usa to europe since I am using a sim from over here but no luck...and added the gprs settings to the phone which allowed apps internet access but zero for browser..any ideas?
I really thank anyone who takes the time to reply...I am sure teaching a new person in this is annoying just as showing the new guy here how to clean his weapon...lol...but we were all new at everything once and I thank you all for reading my novel
-Jay
Jay,
Thank you so much for your service and contribution to our freedom, I know it must be hard to be away from the life you once knew. Hang in there It's not for nothing. Hopefully someone will be able to help with your GPRS settings. I am running the same setup on my captivate only I have used Boogs kernel to install clockwork recovery as well. You can flash boogs kernel over the kernel you have now and that will let you flash roms or speedmods later. If I were you I'd keep my eyes peeled for GPRS settings in your area and wait for EXT or speedmod kernel for the 2.3.4 They are saying RFS is pretty quick to begin with though. It may be hard to beat but im sure one of these great Devs will figure out a way to make 2.3.4 smokin fast. Once again thanks for doing what you do. Keep your head down Soldier!

If you like using your mobile providers Net, you might give I9000 ports a try. They allow for better Upload speeds but you will sacrifice Audience chip support (noise suppression processor that only I897 have). Also since I9000 source usually drop first they have all sorts of kernel mods like Voodoo sound, Voodoo color fix, BLN, init.d files tweaks like V6, among many more. Sadly I897 native roms always play catch up with I9000's.
Personally I prefer native rom, because they tend to run smoother for longer periods of time (I9000 tend to slow down over time on my phone, but thats just my experience) and I don't use ATT's network a whole lot (90% of the time I'm around a wifi connection) and I like the audience chip, it is a phone before anything else.
Edit: Also there isn't a "best" rom, kernel or modem. Each rom has their own pros and cons, same as Kernels. And no 2 phones are the exact same so not all of them take well to all the tweaks, mods, etc. And most of the time i9000 kernels wont work with i897 roms, at least in GB.
I just got myself a Captivate for $120 from cowboom.com. Great phone, just a smaller version of Infuse, which I also happen to have. I really like the fact that charger port is at the top.
Anyways, when making calls, I hear mild but noticeable static which bothers me a bit. When I plug in an earpiece, I only hear it from left ear piece and sound through right ear piece is just fine. Can we tell if this is because previous owner flashed incompatible ROMs/Kernels/Modems, or just a bad hardware? I don't want to return this phone because it has a perfect GPS, but I will have to if the static problem is hardware related.
On a different note, I never knew that GPS on Captivate could be this good. It is a lot better than my Infuse. I had a Captivate about a year ago and GPS on that was a colossal mess. I feel like I need a PhD to understand the inconsistency of GPS chips in Captivates and Infuses.
Thanks in advance.
Here's some more info:
Baseband Version: I897UCKB1
Kernel: 2.6.32.9
Build: FROYO.UCKB1
Modem - I don't know how to find out....
I just rooted it and tried some sound mono conversion apps from the market which didn't help. Thought process was that if I can just mute 'left' and get all my sound through 'right' - that would solve the problem, but none of the apps allow me to change the left-right balance discussed above.
Baseband version IS the modem. Everything running is compatible.
You might want to try flashing a different modem. Top of the development section is a sticky.
Make sure its a I897 modem and not I9000.
If you're rooted then you might want to try flashing a voodoo kernel- that will get you nice sound boost and some clarity.
you can try flashing a different rom/kernel/modem...but if that doesn't fix it then i'm pretty sure that's a hardware problem...
