I'm getting bad reception on my d800. It's a little better on a stock or stocked based ROM and worse on an AOSP ROM.
Is there a way to increase the signal strength?

Are you talking about how much of a difference is there between the ROMs or how much I want to increase it by?

How much of a difference it is, I'm pretty positive that you can't do anything to boost your reception.
And the reason I asked was to see if you're looking st the bars or the db, because if you're not looking at the db then you don't know what the signal strength is

I was looking at the bar, usually i get one to two for AOSP and around 2-3 on stock based. For AOSP, I sometimes get no signal. I thought that the bars corresponded to the signal strength (such that more bars is equivalent to a stronger signal)? Do you know if radio/baseband/modem (are they the same thing?) play a role in signal strength and if they do how?

That's just it, you can't base if off of some system animation, you need to check your db in your settings.
Yes, radio, modem, and baseband are the same thing.
Baseband normally only controls WiFi and data speeds, not signal strength.

Thanks
For the basebands, what are the differences between them for each android version (for example, 10d vs 10o and 20c vs 20y)?
Also for bootloader, what does it do and what are the difference between them for each android version?

Different modems are just updates, but you need to use your devices correct variant for whatever android version you're flashing.
Loki = 4.2 aboot (bootstack)
Bump = 4.4 aboot. Op's typically willbtell you which you need to be on.

Answer me this question... I was on Damage 2.1 Eris leak rom and running fresh's latest radio update and was struggling to get 2-3 bars of EV and after flashing back to 1.5(Gumbo's Bare version) to be exact, i am now getting almost full EV signal steadily I never had an issue getting 1X reception obviously as that's the basic coverage. Not that i'm complaining but what gives? I flashed back planning on following Avalaunch's tip to go back to 1.5 to update prl automatically and then nandroid back to 2.1. This occurred before i did any such update however...
1. Bars mean nothing.
2. Damage only maxes out at 4 bars.
MENU -> SETTINGS -> ABOUT PHONE -> NETWORK
Look at the signal strength here to see what it really is. Don't trust the bars, the bars are a lie! (like the cake)

I apologize I forgot to mention that I did verify in network status so i verified my dBm value is steadily lower(better) -85 to be exact than it was with damage(-95 dBm) on average. and actually i flashed a different task bar on Damage that showed the original 6 bars which is where i'm drawing my observation from.
Actually, I'm with OP on this subject. I tested every 2.1 ROM with the new Radio. I flashed to 1.5 to update the profile and PRL, and then flashed back to 2.1. I then flashed back to 1.5 because I wanted to use Darkstar (theme). Now, you may or may not know, but every 2.1 ROM and Darkstar both use 4 bars. Well, in 1.5 I almost ALWAYS have more bars compared to the 2.1 ROM's. I even confirmed my signal by looking the Network settings menu.

That i can't verify. I would think since it's 2.1 as well it should but i make no claims... nandroid nd try is all i can say. But it definitely gives u a level field for comparing signal reception between roms since it's the same icon as stock.
I've been playing around with all the posted mods and themes under the Hero CDMA forums and unless I'm mistaken all of the taskbars with a 6 signal indicator are nothing more than a remapped 4 signal indicator so you will never see any odd number of signal bars.
Also, it's possible that differences in signal between 1.5 and 2.1 could could have to with the epst.apk. I noticed I can access and modify programming through ##3282# just fine under 1.5 but under 2.1 I always get a FC.

I don't think that taskbar will work with Darch since it is Legend based and that is a droid eris based task bar (I'm running it as well)
when you guys flash back to 1.5 what are you wiping? ext/dalivik only? just curious

1. What's the best version to use?
2. What's the most current official radio, not leaked... thanks.
4.04
4.04
Is that from the e27 update?
Also wondering why you say 4.04 is better...?
thanks
It depends on your location.
4.04 is the latest however I find 4.03 to be the best. Mileage will vary. Try them both out and see which one works for you
I had a bit of problems with the original, none with 4.03, and none with 4.04.
3G issues are highly overhyped.
Don't bother with the radio.
To the average user, there is absolutely ZERO noticeable difference between radio versions.
Anyone who says otherwise is just experiencing a nice little placebo effect
I'm running 4.03... Does radio affect GPS ?

with my T-Mobile Nexus One, i had the best results with 4.03. with 4.04 i had signal drops more often. since switching to the at&t version i've tried all 3 radios and there's no notable difference. all 3 worked well: getting 4 signal bars and consistent internet speeds averaging 3.2 Mbps/downloads and 1.3 Mbps/uploads. fyi, the at&t version uses the 4.04 radio.

Unless Speed Test is totally bonkers I get 2X faster data connection with 4.03 than I do with 4.04. Reception-wise there is no difference between the two IMO.
Two times the speed suggests there is something is not playiing well with 404 on your installation. Never argue with what works though.
Another vote for 4.03.
Was getting CONSTANT drops after the upgrade
EDIT:
Huge thanks to solidmac for contributing his/her test result:

Hi everyone.
There are currently three different versions of radios available for Nexus One Froyo roms.
I conducted a test on all these 3 versions: 4.06, 5.08 and 5.12, and I would like to share my test result.
Link to test result:
https://spreadsheets.google.com/ccc?key=0Ah8PsMa_NqfedERnUmtBWWdJc19OR3lGcmhvR2psMHc&hl=en
(All using unit kBps, kilo-byte-per-second)
My test strategy:
Test both 2G and H data speed.
Phone is put very close to window, no finger is touching on it during each test.
Results provided by SpeedTest.net application.
Default DNS server is used.
Tests were conducted consecutively.
Very poor results (2 occurrences,once with 508 H, once with 512 2G) are dropped.
About Phone:
Nexus One, purchased on 2nd March
CM6 110022010-nightly
Kernel: 2.6.35-7 925mV CFS AVS AIX 720p-Monks-103010
Environmental information:
Cheltenham, Melbourne, Victoria, Australia,
Cloudy, light wind, no rain,
Full bars signal during testing,
Yes Optus mobile company, APN selected to Yes Internet.
Thank you. I was surprised by these results, but its good to finally se some sort of comparison between the radios...
great data!
thx for the data and now i'm kinda regret flashing 5.12 lol
Interesting....nice to see the comparison stats! thanks
Flashing 512 isn't all that bad it has much better ping results meaning it reaches the website first than all the other ones now the only down side is the marginal dl speed

That seems to confirm the results I got from switching the radios around.
I'm sticking with the latest though as it's not clear what other changes have been made, but I ten to believe that newer should be better
Base on the test i wonder if the newer radio only mean for the korean network.
Anyway any data for wifi connection?

I actually thought about testing wifi performance
but that probably won't reflex real radio performance since wifi performance is very constant for me no matter which version of radio i use.
also although 4.06 radio gives sometimes better performance, but I feel 5.12 has significant lower power consumption compare to 4.06
these radios show a difference under bad conditions.. OP if you could run an other test in a bad area or create a bad area ( putting the phone in a weak signal area 2-3 bars ) should show clearer results
Great Works, and now I know how to select radio.

In terms of the ping results you HAVE to omit those 999s, thats not an actual reading of 999, thats saying the reading was 999+ which is not a finite number, so you cant take an average of it.
You've also got such wild spikes of 80% on the H download speeds that, not to put a downer on things, but the results are statistically worthless. You'd have to do a way bigger sample than that.
Since flashing 5.12, I've hardly ever dropped below 3G. I don't really care if it's faster/slower than the others, what matters to me is consistency...
I guess the point I'm making is that you may also wish to look at large packets of data (say 100mb) over a longer duration, and see those kind of results, also?
Of course, network, network loading, location, weather, etc all throw in variables that you can't account for. Only many statistical samples over time can help smooth out the anomolies.
Perhaps my nuclear engineering side is showing?

Haha, well you ARE correct though, network is inconsistent, especially when there are lots of people using data on the same antenna as you...causes a saturation in the spectrum and slows down speeds...
But I second that...do another test with bigger files (if you ever do another test )
thanks everyone
next time when I get large amount of mobile data I'll test again.
I went ahead and did one today hope it provides enough information if you guys have any questions please ask i will try to provide an answer.
Nexus one 5.08 vs 5.12
Nice chart, decided to stick with 4.06_07
Very brave of you to try all the radios
4xx.x version have bad ping scores compared to the newer versions. So pages queue up faster and search and voice to text are analyzed faster. Also the newer radios are more stable with their speeds especially in the wifi and 3g.

Hey mate
thanks for your test result
but i was wondering, why do you have test result on 5.09 radio.. did it work on Nexus One? I thought 509 radio was for Desire
I think that was just a typo. Should be 5.08
I'd hate to make a new thread, but I really did look around.
I just rooted my phone and installed CM7. For whatever reason, I'm only getting 2 bars of signal strength, and just that on wifi.
I followed directions when installing the CM7, I don't know what the issue could be. Help would be appreciated.
Thanks
Would you say that your speeds and etc. are slower now? I know I've had some issues with CM and slower 3g speeds, but just because your bars are low doesn't exactly mean that you aren't getting the same speed you were before.
Are you noticing obvious slowdowns?

I don't know.
I just tried Speed Test 724kbps download and 250 upload
Are these good numbers?
I'm having an issue that I don't understand and I'm hoping someone can help or at least explain what's going on. My phone carrier is MintSim which uses the T-Mobile network.
If I use OOS or any OOS based custom ROM I get a great phone signal--full bars in every room. If I transfer the sim to my Nexus 6P which is running Dirty Unicorns (an AOSP ROM) I get a great phone signal with full bars in every room. But if I flash an AOSP ROM on the OP5 my phone signal is poor to non existent. I have tried 3 different AOSP ROMs on the OP5 and I couldn't get a decent phone signal on any of them.
I've never run into an issue like this on any other phone. Can someone explain why this might be happening?
You shouldn't judge it by bars. Many manufacturers like oneplus and even samsung will make it look like you have full signal strength even though you don't. Roms usually report it correctly. Use a signal app and it should show the same signal strength in dBm

In Aosp I have two bars to none. I have also tried to make calls and was told the quality was poor. On top of that I'm using an Aosp ROM in my other phone and it shows the same signal strength as OOS. On all 3 Aosp ROMs I tried on the OP5 the signal was so unstable the signal bars never stayed the same for more than a few seconds.

I've never come across that issue on a previous phone. The only AOSP ROM I've gotten no complaints from people I called is Viper. The signal meter on the OP5 is really inaccurate on AOSP ROMs. I installed a signal reader app. It showed an excellent signal but I only had a couple bars according to the icon at the top of the screen.
did anybody able to figure this out, tried a lot of AOSP i think all of it, but signals just dropped out most of the time, followed flashing requirements on each ROM, went back to OOS stable 5.0.2 now 5.0.4 signals stick all the time, gps works perfect...just wanna know coz I still prefer AOSP esp the LOS 15.1.

It's been like that since OP3.
Will likely never be "fixed" at this point. Just get used to it, some recognized developpers declared it is only a "visual" issue.
I guess there is nothing to do about it...
I returned from LOS to OOS just because of that. It may be only visual, but would you ignore warnings on your cars engine? Bad signal means the phone tries harder to aquire it and it means more battery drain. I wouldnt really go with the statement its just a visual bug, especially on LOS where they have set the bar quite high in quality by themselves.
