Can someone explain to me what ASU is under call signal please

I was wondering what ASU is under the decibel reading for signal strength my evo 3d and epic touch sit at the same signal strength decibel wise but the evo 3d has anywhere from 6 --12 ASU while my epic touch never changes from 0 ...call quality is far superior on my epic, that's with zero bars while the evolution 3d has four hence the reason I was checking the actual decibel readings ...I think the DB is for decibel if anyone can explain I will reward you with a cookie.

Scroll to the bottom of the page here

Note that the android meaning is different than the traditional meaning, which that page explains.

I actually read that already but more or less was wondering why the Evo 3D gets around 6 - 10 ASU and my epic gets zero, assuming the bigger number is better tho my epic blows my 3d out of the water with call quality and dropped calls reception etc ...

Did you make the changes to the EVO 3D call quality using the EVRC-B enable method?
Signal strenght and call quality dont necessarily go hand in hand. Both devices can be in good signal strength but if the encoders/decoders are different that can have a noticeable effect on sound quality.
The 3D incorporates a new protocol for the CDMA handling of the calls. I think over at XDA this was discussed and there is a process to be able to enable or disable the cause of the poor quality.
I have the instructions but not sure if i am allowed to post them. PM me or go to xda and do a search.
I tought they were on this site as well but i did a quick look and couldnt find it.

I left all call settings stock on the 3D ....its a awesome phone but the call quality is far better to me at my home and work locations ...ofcourse this is not fact its just my opinion and my experience with both units
