Well, so far I like the JVK modem. It works very well in all aspects. I do have 2 concerns and will need more time on this modem. First is that the battery seems to be worse BUT, I just flashed back to stock and back on Cogv4 again last night.So I need a few days for that. Also the voice quality is good but I think that JS1 may be slightly better. I need more time to compare..... The differences aren't obvious that's for sure.

It handled data very well at very low signal as well as voice. Also while driving, there were no obvious hiccups or anything while talking and it switching towers and bands.

Updated OP with more info about the modems I found while doing a hexadecimal resynchronizing compare between them.
[Captivate Android Development] kable41:
Ok i am relatively new to all of this custom roms phenomena for our cappy's but i would like to know plz in simple terms which of all of these modems will work good for Cog2.3b8...which is what i have now..i love it so much and i would hate to have to flash to another rom (i9000 based) just to be able to get hsupa so if someone could tell me which of those roms will get hsupa so i can start trying them out! thanks and cheers!
[Captivate Android Development] x3nhydr4lutr1sx:
These will not work on cognition 2.3b8 because cognition is I-897 Rom, while these modems are I-9000 modems. So do not download of any these modems, you will run a high chance of bricking your phone.
[Captivate Android Development] Pirateghost:
LOL

you wont brick your phone by installing these modems, you just need a kernel that is compatible with them.....this isnt rocket science
[Captivate Android Development] xtremesv:
I've flashed VJJPD modem and I'm giving sometime to decide if staying with it or changing for UGJL2 but so far so good. Thanks.
[Captivate Android Development] silverslotcar:
Brick from flashing an i9000 modem on a cappy rom!!!! LOL thats hilarious
[Captivate Android Development] x3nhydr4lutr1sx:
I've been running I9000 roms (Darky right now) and been using the tl3 modem. I simply got my marching orders about keeping i9000 roms with i9000 modems from this text:

which I got from this link: http://xdaforums.com/showthread.php?t=835272

I recall that cognition is running a cappy kernel, not I9000, hence I gave that advice. If it's okay to run a 2.2 modem on any 2.2 (I9000 or otherwise), then perhaps editing that thread would prevent further confusions.
[Captivate Android Development] xtremesv:
Just reporting.

I tried BVJJPD and UGJL2 modems. It seems that BVJJPD gave me better performance overall (signal/data/GPS) at a little bit higher battery drain than UGJL2. As my result is empirical though, I'd appreciate if someone who had experimented with these 2 modems could give a feedback about their outcome. Thanks.

UGL2 is fast but it drops too many calls in a busy area.. It does not switch from 3g to 2g until is too late and the call drops.. the fastest internet but not the best for keeping phone calls.. too aggressive..

No matter what modem I use I cant get away from cell standby percentage. Anyone have any ideas? I am using superpower app. Would that have anything to do with it?

Added the I9088ZNKP1 modem (first 2011 modem) to the OP. I haven't tested this yet, but looking through the other posts it does have the 850 band. Please post some feedback when you get a chance. I will check it out later tonight
[Captivate Android Development] existz:
KP1 is by far the best modem ive used yet, I was using jk3-jk4 back and forth, but with KP1 I got 0% drain over 8hrs idel, (was getting 1-2% with jk3/4, 5-10% with jl2/3... With normal use during the day, KP1 seems to be excellent in that department as well, im monitoring battery usage now, after 8hrs use i will post my results from SystemPanel..
[Captivate Android Development] phoenix2217:
trying this out now --->I9088ZNKP1. so far so good I suppose. GPS is FAST. Within 10 meters, ~10 sec lock time. Showed exactly where I was. Stayed locked while moving. In terms of upload and download, upload is fast. about 1100 Kb/s. Downloads, not so much. Only about 500 Kb/s while on the 850 Band. Going to continue testing, but these are my first thoughts.
[Captivate Android Development] garringm:
As I can't give opinion on js1 I will agree with shoman on jvk, Call quality for me is A+, It never missed a beat even while talking through my mile long stretch, I lost a couple calls but those were on the other end. I got decent reception at work today now the rest of the evening will be spent with more testing.
[Captivate Android Development] Sqb:
Been on jvk for the second day now. For me it edges out js1 all around. Not by much but enough to get two bars instead of one in the black hole I call home. I can actually walk throughout the house on the phone instead of running for the door each time the phone rings.

[Captivate Android Development] geokilla:
For all you guys that are saying how modem XXX is so great, how do you actually tell the difference between all these modems?? Testing the signal and data is easy since you can just mark a spot on your table then put your phone there before and after the modem, and data you can just run SpeedTest (which is just a benchmark). But for other stuff like call quality.... Please explain.
[Captivate Android Development] froli13:
@shoman94: JVE works perfectly on my phone! It changes band when it has to, prefer GSM if signal and stronger and vice-versa. Download speeds are as good or better as JK4. It's overall great so far. I'll stick with it for awhile.
[Captivate Android Development] shoman94:
There is no scientific way to test voice quality that's for sure. I shouldn't even have to explain that to you. But here goes.....

I leave myself voice mails while in different environments like drive in a car at highway speeds, or in room with a loud TV, or in a city background with lots of noise... then of course a nice quiet area. What I'm looking for is for is that voice mail I just recorded to sound like "me". Not muffled or digitized or with static.

I'm also testing data. I work in an area (steel buildings) that service is tough. I test how the modem can handle the data with signals as low as -110db. I'm looking for the endless hang or timeouts etc.

I don't know if that's what you're looking for but that's it in a nutshell....
[Captivate Android Development] shoman94:
Excellent! Let me know how it works out for you. I liked that modem as well.... my only issue was how it handles data down below -105db. I had to many timeouts while searching XDA while sitting in my car in a parking garage. Probably 50% of the time it would time out on me. Then I installed JPG right then and there....and it was about 95% successful.

Hopefully it works out for you and I'm all about find the best modems that we can.
[Captivate Android Development] shoman94:
I don't agree at all. JS1, JPG and JQ1 have excellent battery life at idle. IMO jk4 uses the same battery as those when in use but at idle... definitely more.
[Captivate Android Development] fractaline:
+1. For me both jpg and jq1 have far superior battery life in idle. I can stay at the same% for nine our ten hours data off cell on.

[Captivate Android Development] garringm:
I do the speedtest exactly as you say But similar to shoman, I have a low signal almost everywhere I go in the -100's constantly thats why Its important for me to find a modem that has a stable not necessarily fast data connection, again I'm not too worried about battery life. I prefer Benchbee just for this personal preference.

Somewhat similar situation similar methods of testing but when my wife or someone starts complaining I sound like Im in a tunnel or they are constantly asking me to repeat myself its time to move on. So far JVK is working extremely well no complaints good find shoman

For all others I would recommend instead of asking which modem is best, you need to do a little leg work of your own, there are so many different variables and ways you may use your phone than the next guy, you really need to find a modem that suits your style. The only thing shoman or anyone else can do is give you a good starting point and a generic "This should work" I personally recommend jl2, jpg or jq1 in that order jl2 being first for the newbies it just works
[Captivate Android Development] Sqb:
I use the good old ask my wife if she can hear me trick. Helps that I have these damn coqui frogs that sound like fire alarms constantly chirping in the background once the sun goes down. As far as data I also judge by how solid the the connection is. If it can hold on for dear life in the black hole then its a go

So where can we get our hands on JPF? :-) and lucky you that you got JS1 working. I couldnt get it to work for nothing. Always a x - no service

[Captivate Android Development] fractaline:
How's that for best of both worlds ....it's jq1 at no worse than -75dbm

[Captivate Android Development] MPKO:
I wouldnt recommend speestest as a benchmark because it debends a lot of resources of you operator network. Bit I f you still want to do it and validate the performance based on that, then you should do it at night time when "normal" people are sleeping...

[Captivate Android Development] timn2bama:
How I test these modems. Well I just call my wife and daughter and ask if it sounds good they will say I'm muffle sound then the modem is a good to me.

[Captivate Android Development] garringm:
If they say your muffled you would probly want to try a different modem, I look for the clear precise sound I've even had my wife call me from my phone just so can hear what it sounds like.
[Captivate Android Development] shoman94:
Exactly...that's when my speed test numbers are done. After 10pm.... Before that the numbers aren't as accurate..
[Captivate Android Development] shoman94:
I can upload it this evening when I get home. It's not a bad modem. It has good data speeds especially on the upload in 1900mhz.... Over 1mbps consistently. But I'm back on jvk so I can continue testing that one.

I wish the xda-app allowed uploads of files.
[Captivate Android Development] fractaline:
I look for an over all average of speed tests (and signal strength and gps etc...)in different circumstances.....seems like the best we can do....the difference between it's ability to to keep a flow in adverse conditions and the optimal situation the lesser the difference, the more reliable the modem...simple logic, complex results...

Been on jvk for a couple of hours. Seems to hold on 850 band veey well after the tricky flash order.

Gonna post results a couple of days later
[Captivate Android Development] geokilla:
I noticed that if I flash any modems using the flashing trick, the modem will stay on the 3G band and never revert to 2G. Placing my Captivate in the same spot of bad service, I noticed that it will readily switch to GSM850 which seems to have a stronger signal than WCDMA850.
[Captivate Android Development] MaxRabbit:
Did you follow Shomans instructions? See my signature link.
[Captivate Android Development] timn2bama:
Oh yea I do and the one modem works well for is KP1. It has louder earpiece for me to.

Really liking JVK especially for upload speeds. Download speeds vary trough the day and I get almost 4mb after midnight!
[Captivate Android Development] eliminat:
I noticed that my phone wouldn't connect to gsm until I disabled and reenabled them in *#2263#, even with no signal, using jq1 and jvk.
[Captivate Android Development] geokilla:
Yep. Of course. It's the only way to get JVK to work properly.
[Captivate Android Development] mrhaley30705:
I have tried JVE, JVK, JS1, and now JPG. JVE so far has been the best FOR ME. But i just flashed jpg about an hour ago. And Yes i did follow shoman's instructions. Twice. First time i screwed it up. Worked like a charm since,
[Captivate Android Development] shoman94:
Once you are complete with the install... meaning you re-enabled all the bands.... you have to reboot for everything to work properly again. not rebooting after re-enabling all the bands will leave you with just wcdma850. I'll update my sig if I didn't mention that.

Yowser.... Thats a fast upload.
[Captivate Android Development] geokilla:
Yea I did reboot. It still stays on WCDMA, whether it be 850 or 1900. Still refuses to switch to GSM.
[Captivate Android Development] shoman94:
Well if you still have 3g the modem prefers that and will stay there...

There is an option I posted earlier in the modem menus..... You can change it to prefer GSM. http://xdaforums.com/showpost.php?p=12420727&postcount=721

I'm not sure how it works but I believe it will prefer whichever network has the most towers in the area.
[Captivate Android Development] geokilla:
Thanks I'll give that a try and then reboot the phone. Btw, you have to go into Network Control, then Acquisition Order.

Oh, and the automatic doesn't work... Let's see what happens if I select GSM > UMTS.
[Captivate Android Development] shoman94:
I know... I posted the link so you could read it...
[Captivate Android Development] froli13:
Sorry guys I know it's off topic, but what theme is that? And where can I get it?
[Captivate Android Development] LNJ:
I'm on Continuum. I customized it in UOT Kitchen. There are 2 white taskbar options. I picked the CDT one I believe. And the signal bar etc is the Gingerbread kind. And the battery is also customizable.
[Captivate Android Development] harpo1:
JVK has the best data speeds out of all the modems I've tried. Call quality on the other hand wasn't very good for me at low signal strength. Here in Northern California where I live signal sucks so it's back to JPG for me. I still have a few more to test before I settle on my daily driver.
[Captivate Android Development] geokilla:
I meant that you left out a step in your instructions.

And update, it stays on 3G. Doesn't revert to GSM.

The limited amount of time I spent with JQ1, JS1, and JVK, I didn't find much difference compared to JK4. Maybe because I'm not a hard user like you guys. Of course, I haven't done the "voicemail test" yet, but everything else feels and looks more or less the same to me.
[Captivate Android Development] fractaline:
For me the battery life in idle is the biggest attraction...

Data speeds are more consistent, but not really alot faster. Although I got mybest overall result from jq1. 4.6 dl 3.5ul

Using jvk at the moment, still feeling them out

Have any of you checked the settings in *#*#4636#*#* from the dialer, under Phone Information? I just changed to WCDMA preferred to see if it would help keep my phone from falling to Edge, then staying there even after I'm back in an area I know has 3G.
[Captivate Android Development] ccdoggy:
on JVK for the past 5 days or so. was getting like 5% drain per day, then enabled juice defender to disable the cell and wifi data when locked. now seeing about 25% draw a day where with jk4 it would be 60%+. few calls, few texts, little gaming.

I dont get my texts or anything for a while but i am ok with that.
[Captivate Android Development] lbbo2002:
Has anyone had issues following Shoman94 instructions? I cannot get JVK, JVE, XXJQ1 or BUJS1 modem to work unless I do JK4 --> ZNKP1 --> XXJQ1 or any other modem with our using ZNNP1 as the middle step.

If I use BVJJPD or BVJJPG I get 850 on that boot but flashing the XXJQ1 or any like modem will not have 850 enabled. Why would either choice not work when KP1 does ?

Very confused what the issue is but I am now on JQ1 and testing it out. I plan to test the rest over the next week.

Just a data point but from Austin/Houston TX locations JQ1 is 20% faster upload than JK4. Battery drain seems the same but I have only been using it for 15hrs.
[Captivate Android Development] garringm:
I stumbled onto that a while back, fortunately I can use both methods but I cannot get js1 modem to work no matter what I do.
[Captivate Android Development] olo567:
Was at a Phillies pre-season game. Using JVK, flawlessly switched automatically between HSDPA and EDGE. The AT&T load in that park especially is usually pretty bad, so if my modem stuck on HSDPA like stock and my old phone did, texts would take forever to send and data? Forget about it. JVK switched down to EDGE and avoided some of the 3G load and things actually went much faster.
[Captivate Android Development] mrhaley30705:
If I flash a new rom(wipe version), do i have to go through this process all over again to use these unique modems?
[Captivate Android Development] shoman94:
If you don't go to stock and you incorporate the modem within the RoM flash you should be all set. I have successfully done it but it may vary. Try it and if it doesn't work then you just have to reflash them.
[Captivate Android Development] shoman94:
So you are enabling 850 only in JK4 before flashing to JJPG right? I have heard of this happening to someone else.... he is in a 1007 build version of the phone.

But if you followed it verbatim and the only way was through KP1 that is fine... what ever works for you. So if that's how it has to be for some I can update my instructions to use KP1 if needed.
[Captivate Android Development] mbc663:
How is your signal with jq1? I'm in the same area and its not doing too good for me. Jk4 works best for me
[Captivate Android Development] mrhaley30705:
well, I probably need to do a master clear and stock flash. I (stupidly) flashed an addon to Apex while running Continuum. It didn't soft brick the phone, but some of the icons are screwy and i didn't want to take a chance. I thought that would be the answer, but i was hoping i might be wrong.
[Captivate Android Development] shoman94:
I'm gonna post a quick statement on my testing today.

I moved to a new location in the building at work that has very poor signal. Like the center of a 500,000 square foot metal building that has cement wall within it. Sitting at my lunch table I have a wcdma850mhz signal of -110 to -108db. Using the XDA App I was getting timeouts about once every 10 threads. So I flashed JS1 and I was getting about 7 timeouts for every 10 threads. Then I flashed JPG and got the same as JS1. Then I flashed JQ1 and then JVE.... Would timeout everytime. So for ****s I decided to try the modem that everyone claims is the best.... JK4.... Time out everytime. At least with JQ1 and JVE I could get it to work if I moved a bit to get the signal up just above -105db but JK4 still would time out. So then I flashed back to JVK and was back to 90% success rate at -110 to -108db.

So for me JVK is the new king. Samsung did an excellent job with this modem. Very good sound quality (only edged out by JS1) great data pull and great speeds. Battery life is excellent with 1% at idle per hour with my GMAIL push email active, GPS off, WIFI off, Bluetooth off, Auto rotate off and auto display brightness ON.

Thanks for listening.
[Captivate Android Development] shoman94:
I agree that it is an excellent modem.
[Captivate Android Development] shoman94:
So if you are still running Continuum and are gonna reflash Continuum then then you shoulld be all set. Actually if you look at the First post on Continuum v4 You'll see in the addons link there is a flash back package for both Themed and non-themed. Then you'll be all set.
[Captivate Android Development] Nucleartx:
Working on JVK now, seamless switch on 1900/850. Decent battery life, minimal upload lockups. ALOT better voice quality. Just going through full batt charge still so can't report on it.
[Captivate Android Development] mbc663:
I like jvk so far myself.
[Captivate Android Development] {Angel}:
I managed to get ZSJPG working a bit differently. I just flashed BVJJPG, then I selected WCDMA850 only. Flashed ZSJPG and 850 was working. In my case BVJJPG and I suppose BVJJPD is the only "bridge" modem I need, I didnt need to flash JL2 or any other modem. Maybe this can work for others, but Shomans method seems to work for everyone.
[Captivate Android Development] shoman94:
What were you on before?
[Captivate Android Development] grkmaster:
WHat ended up happening with JPF?
[Captivate Android Development] {Angel}:
I was on XXJQ1 with no 850. If this works for more people then the flashing procedure got a bit easier.
[Captivate Android Development] shoman94:
Not sure I understand..... with no 850 do you mean 850 wouldn't work at all?
[Captivate Android Development] shoman94:
I didn't test it yet because the voice quality with loud background(In the car at highway speed)it wasn't as good as JVK but it was nice in my living room with the tv on. Data speeds were on par with JS1 and JPG but did have 1900 upload similar speed to JVK.

I forgot to post it so others can try it. :o
[Captivate Android Development] mbc663:
Where did this come from?
[Captivate Android Development] {Angel}:
I flashed a stock JS8 that cones with jq1. Then i flashed jjpg to get 850. Then i flashed zsjpg just to try it out.
[Captivate Android Development] harpo1:
JQ1 doesn't default to 850. You need to install JL2 or 3 and go in and enable 850 only. Then load JPD check to make sure 850 is still enabled then load JPG. Finally go in make sure 850 is still enabled then select auto select and you should be good to go.
[Captivate Android Development] {Angel}:
Shoman how is jvk compared to jpg?
[Captivate Android Development] shoman94:
I found it.... lol

I'm always looking for the best modem you know?
[Captivate Android Development] {Angel}:
Yes I know I was just explaining how I got JPG without going through another 850 modem besides jjpg
[Captivate Android Development] shoman94:
Interesting... that could be but most people from here in the USA are coming from either one of the 4 modems I mentioned in my SIG post. So to make things easy and consistent, I added that if they were on either one of those 4 modems they could just enable 850 and go from there. No need to make it complicated since there are so many options. Also once you're on one... no need for the process from there.

Not sure if you read my latest edit.... I changed it up a little.

IMO JVK is better at very low service data and speed. I commented on it earlier...
