trying to break this down so that i get my questions answered. here it goes
im running CM9 build 17 all stock. on the optus network in Australia. a bit south of Melbourne but it shouldn't really matter where i am as long at im near major civalisation right? i mean i could go anywhere in aus and get the same results for reception and calls as long as im near the towers?
im looking for a good modem for me to use on the network, i have been looking at the voodoo majick that is nexus s modems and dont want to go there, they look silly. no 2g sometimes and no one is realy testing them. there all getting half baked results. and who knows what problems they havent encounterd yet.
ive tryed a few modems including offical optus modems and they dont seam to be the best performers sometimes. bad batterylife or slower network switching or bad call quality. what bands should i be looking for. i see alot of people looking for 850 bands but i dont think optus uses that one. what networks do here anyway? i know telstra do.
links or information will help give us anything and everything. ie try this/read that so on. i want to be informed for the future as well as a good kick in the general direction of go do it yourself in that direction.
Look for siky_dude 's modem thread, get radio-cm-7-ics-SGS-XWJW1-signed.zip and radio-cm-7-ics-SGS-XXJW4-signed.zip, try them, and read the thread for more info. Also look for the Australian thread. Good luck. And search moar

Ok I've been searching the forums for a while now to find answers to my questions and I've answered a few of them but I think I need a little more advice.
I'm using the HTC Touch Diamond and the Model NO shows DIAM500 on the back I've got MP6950, ROM version is 1.22.557.1, Radio Version 1.03.06F. I'm a CDMA user (Pretty sure anyway) and my carrier is Cellular South.
I love my Diamond it's just my carrier that seems to be a problem. I live out in the boonies so my reception is virtually non-existant at home. Not a major problem but an annoying one. It's not just with the Diamond it's with every cell phone I've ever had. Also the battery life could be better I think, I get about 4 hours with pretty moderate use while I have signal (at work). Haven't really done any tweaking YET but I've started messing around today.
Now this brings me to the reason I'm posting. I was looking into updating my ROM but was not able to download the latest from the HTC site (I figured out why). So as far as ROM's go I'm a little confused with all the custom ROMS posted here, I don't really know which would be best for me and if they will work at all and not screw up my phone. Can anyone offer some advice on what ROM is should use?
And I also want to play around with different Radios because I'm under the impression that it could help my reception issue, and then again it probably won't since I've always had this issue. So has anyone had luck with a certain radio helping poor reception? Is there one that would be better for me than the others?
I'm sure these are fairly regular and annoying questions but I just want to make sure I don't throw away the purchase I just made by updating the ROM and radio.
Most of XDA Forum is not for CDMA.
You can always find custom ROMs. Each ROM is different from the others (included applications and options which affect memory usage and performance). So there really isnt a "best ROM." You can check out the thread for CDMA ROMs and make sure you know how to install new ROMs and that you have the needed applications (HardSPL for GSM I dont know if its the same for CDMA). If you have what it takes you can try several ROMs and radios to find the most suitable one for you. Normally this shouldnt harm your phone unless you dont read well before attempting.
Hope this helps.
Hey sorry if I'm posting something that has already been talked about, I know I'm new. After I installed serendipity I have been having really bad reception (I had excellent service everywhere before). I'm with Rogers in Ontario, I've read that my phone may be looking for a faster/more powerful tower, and disregarding a closer slower one? Any way to fix these settings? I would prefer not to reflash haha.
Thanks for any help
Could always try a different modem [Modems] - (Froyo & Gingerbread) - WCDMA 850 enabled
Just found that the JK4 modem works best for me in my area. Anyone in southern Ontario should try http://forum.xda-developers.com/showthread.php?t=867309

So I read that it was not possible ti get a captivate modem/rom to support 4g/hspa+
However I read several ppl on here get the h+ with their captivate?
I look thru the roms but none say hspa+...
Can someone help me out and tell me which rom I can get the h+ with?
3g ib my area is terrible I get 50kbps if I'm lucky, and h+ is available here...
Thanks so much. I really hope its possible, I love captivate and would hate to have to get a new phone...

Unfortunately, our phones don't support H+. We can get HSDPA, and the i9000 modems can get HSUPA, but that's not true H+. However, if HSDPA/HSUPA is acceptable, try flashing an i9000 modem/kernel/rom setup and see if that works for you.

if 3g in your area is that crappy, dont think that hspa is going to fix it. it all rides on the same bands/frequencies. hspa+ is just an increased 3G. in my experience with all my '4G' devices, excluding my LTE ones, obviously, its no different than rocking an i9000 rom/modem on my captivate.

To clarify this one thing for ya...
Those reporting the "H+" on their Captivate were more than likely running one of the previously leaked i897 firmwares, that had that built into the leak itself. So nothing official and probably someone thought it would be cool, funny, etc. etc.
The latest i897 leaks are back to just showing the "3G".
Anyway, just an fyi.
so i have a captivate, i love it. however my carrier has limited service where i live. i have seen people say they get better download and upload speed with different modems and i myself have flashed different modems and used speedtest app to see these differences. my question(s) are really as follows
can a modem give you better reception?
is it possible to make your antenna in your phone work harder to pick up better signal strength?
in general is there a way i can learn how modems work?
thanks smart peeps!

First, a modem us the binary file that runs the antenna. So if we were able to control and edit the binary (which we can't) you could potentially make the antenna "work harder".
so a modem works by controlling, software wise, the frequencies the antenna uses. For example, I9000 modems tell the antenna to also pick up hsupa, and that is why I9000 based roms have faster data. The modem needs to also be compatible with the kernel so it can run properly. This is why e can't use modems like JK4 on captivate based Roms.
flashing a modem can increase signal. It is all about where you are though. JK4, which is a great modem in Boston, might not be a great modem in San Francisco, or Detroit.
there is a sticky thread in the development section for this with a website that will help you pick out a new modem. Make sure it is compatible with your kernel first.

There is not an easy answer to this (I don't think) but here is an interesting read that may be of some help (or at least an interesting read )...

True... Detailed.. However, mostly irrelevant..
When you flash a modem, you're flashing an operating system for the communications chip. It's an entire stand-alone operating system designed to minimalistically receive and transmit data. The communications chip is capable of running an entire device. This is evidant when you examine the binary. It contains keyboard, mouse and display drivers.
When the Captivate was released, it was released as a 3G device, not H, so its communications chip was configured to work as a 3G modem. This was likely a marketing decision as "3G" was all the rave at the time.
A modem won't improve your reception unless your old modem was configured incorrectly
As far as signal strength, it won't improve unless your old modem was configured incorrectly.
There are several tweaks which are applied in each version of modem firmware for different devices. Unfortunately, the communications chip is locked down/Closed-source Qualcrap.. So, we will never fully understand what configurations are available, nor can we do anything other than test and see which one works more effectively.
hey thank you so much guys, this is really interesting, sadly a little depressing but interesting. i have one last question then, since i am running my i897 captivate... with the ICS rom, does this mean i should use i9000 or i897 modems? i heard that i9000 modems were just better then i897 so i am using them... but if the above is true, i shoud be using i897 to get proper configuration of my device.
you guys are all awesome and ill be mashing the thanks button!
<3 Gorship
U have to use the specific modems for ICS... See here... http://forum.xda-developers.com/showpost.php?p=16843698&postcount=1
And more specifically...See this page... http://soggycashew.weebly.com/cm7miui--ics-modems.html
yea im flashing a few of the ics i897 vs the i9000 i was using... still though... i have full bars with my old blackberry bold 9000 compared to my cappy which has 1 or 2... i dont understand why.
Hey all,
First off, big fan of Oxicottin's work over here:
http://forum.xda-developers.com/showthread.php?t=1227717
but I live in a part of the country where there's still no feedback from anyone nearby as to which modems perform better/worse with radio signal/data/etc. I've tried plenty of modems myself, but they all seem spotty and it's tough to make any kind of legitimate judgment as to which performs best.
That said, does anyone know of any software out there to track modem performance for us? As in, flash modem X, run an app in the background and let it record signal data as you move throughout your day, then do the same thing tomorrow with modem Y/Z/whatever and then after a week you have some solid information.
If not... any brilliant devs out there who want a new challenge? Seems like a tool that could potentially benefit... everyone.
P.S. Yes, I've searched already with no luck (xda, market, google, etc.).
Best thing you can get is speedtest from ookla on the market. You can run it after flahsing the modem and check upload, download and ping speeds. It also keeps a history to make comparisons.
I second this. I think it would be a really useful tool to audit different modems. Speedtest is nice but it doesn't really tell you how good your overall experience will be. If I had any coding knowledge, I would attempt making an app myself, but sadly that isn't the case. Hopefully someone will turn this idea into reality!
definitely appreciate the tip, i'll give it a try. have to say though, i'm one of those weird old-school people who would rather sacrifice data speeds than call quality/consistency (yeah, i know...). but i guess i can just assume that the best data speed also means best general modem performance (not sure if that's true or not but hey, beggars can't be choosers i suppose.)
