Now I'm going to try the 1.12.31F from Cellular South and see what I can do. Note I just got a new (refurb, but still manufactured in Feb) Sprint TP yesterday so I'm tinkering.

And if anyone wants to know what SMV is, it stands for Selectable Mode Vocoder, and it is a newer voice codec than EVRC, which is what carriers use currently. It isn't as new as the 4GV standard EVRC-B or EVRC-WB, but it has noticeably better call quality than EVRC while being more bandwidth efficient. EVRC-B is even more bandwidth efficient with higher call quality than EVRC, but in most opinions isn't as good as SMV. EVRC-WB (WB stands for WideBand) is the sister codec to EVRC-B and is a 4GV standard, but I haven't tested it much and the only way to enable it is through QPST. I haven't had much luck with the TP and EVRC-WB and Qualcomm won't say exactly what MSM chipsets support it. Let's just say I need to test EVRC-WB more to say it is useable. If it is, then it would be the preferrable vocoder to use.

To enable SMV, you need to punch in ##PST#, select edit, put in your MSL, and select CDMA settings under the "View info" menu. Set EVRC Enabled to "Disable," set Home Page to "SMV," and set Home Orig to "SMV." Roam Orig is optional and you can use EVRC or SMV, but to avoid any problems when roaming, I'd advise keeping it set to Voice 13K.

that's all incredibly difficult to read, but thanks for that because i was wondering what dcd was talking about
side note: does the fact that when i seen "smv" i thought "shadowmoon valley" make me a nerd?

In short, the carriers still use a Voice Codec from 1995 on their phones, when their networks and phones can use much newer Voice Codecs that provide noticeable improvements in voice quality while using less bandwidth.

Call it laziness or just stubbornness to go to the new codecs on the carriers' part. I wish they would implement the use of EVRC-WB as it can push 8 or 16 kHz sound with a comparable amount of bandwidth.

Thanks for the very useful post! What kind of problems can occur by changing the Roam Orig selection from Voice 13K to something else?

Does anyone know if these correspond to specific registry settings? I'm interested in incorporating this into UC.

Thanks in advance. Great info!!

Unfortunately, the only way to change these are through EPST or QPST, as they are not Windows settings; they are stored in NVRAM. You also need the MSL of the phone.

I successfully enabled 4GV/EVRC-WB, but I haven't had sufficient chance to test it. The only calls I made were muffled, probably because I was calling someone through a VOIP trunk to a cellular network. That causes transcoding twice after being encoded in 4GV WB.

Plus, 4GV-WB can be stepped down to 8 kHz on the carrier side, further degrading quality.

Mutiny32,
Thanks for the great info man. Let us know how the testing goes with the 4GV/EVRC-WB.

thanks

what ware the advantages of using this? after finally reading it i might try this out but im just wondering what the advantages are?

[JDown24]

i have been trying to use the ##DEBUG# and i get a password screen. I tried using the default password that i use for changing the PRL but its not working. Is there a different default password for this? I really wanna check all my info before changing the radio so i can get a better idea of the best one to use where i am at.

Never mind, finally found the password, go figure, i search for an hour and finally post for some help, then i find it 5 minutes later

Just an update, if anybody else has this issue the password is 183729

Is there a way to tell what's the latest radio added? Is it worth showing the date the radio was added?

the date someone found, extracted, or posted the radios here would have no relation to the date at which they were compiled by htc, so i dont see how that info would be useful.
