yes you can

any Qualcomm chipset usb modem and can detect by QPST spftware all can tweak,.

ok2, i will try this tweak now

bro chuahcs79, what value suitable with e367? -444?

a few pages in front did have some user feed back -200 for E367 as it is single channel modem ,

for DC_HSPA+ modem can up to -450,.

of course, the actual number u need to tweak and test it one by one to see which is works best for you in your area

For huawei e355 what is the best value??

LOL, E355 dont support,

You sure you manage to tweak your E355?

cant detect the modem emm but the speed is good by now using maxis

54pages, about half a days to read all the info, -.- but it useful to me, hehe

i have done this tweak at my e367, and now, it works
thanks sifu chuahcs79 and sifu blacktubi


before tweak, -101dbm
after tweak, i can get -77dbm, > -83dbm, what a huge difference!
and sifu blacktubi, do you have a stock available your "Panel Antenna", who know my signal can turn to -55dbm.. heheheh

my e367 limited to -300 only, up to -310 and upwards, my channel wcdma not showing, only gprs & edge only -.-

and the boost, what a suitable value reccomend for my e367?

huawei E355 is consider router,. that's why it is not support

Hi blacktubi,

Thanks for a great Qualcomm chip modem 'SuperCharge' procedure ... I'm from Australia.

Whilst I understand the first step:

1. The first tweak boosts the Tx power by 3dBm (+23 to +26dBm)

Go to this value, change it to 26
NV_WCDMA_MAX_TX_POWER_1

Now +23dBm is 0.2 watts and +26dbm is 0.4 watts (3db is double the power).

So this is very significant and might just be something to help those on weaker or even congested links gain a reliable connection?

I think for most modems, the default value will be '23 or 24'?

3G output power is defined by the device power class. I think this document shows the relative UMTS power class levels: http://www.wayland.ma.us/Pages/WaylandMA_B.../powerlevel.pdf

Class 1 +21dbm

Class 2 +24dbm

Class 3 +27dBm

Class 4 +33dBm

Has anyone tried values >+26dBm?

The down side is that the modem will likely run a little hotter!

2. The second tweak is doing something to the Rx antenna which I don't profess to understand:

Go to this value, change it to -444 from (-100?)
Depends on modem, the value are different, test which one that works the best for you
“NV_WCDMA_VGA_GAIN_OFFSET_1”

What does the second step actually do to the modem internal antenna(s) and what to the values mean?

PS I presume the usb modem drivers must be installed for QPST to function?

Cheers

Hi there, I am partially from Melbourne mate, nice to meet you

No worries, although at higher TX power but with a reliable USB output power, it is okay

From my research from internal Huawei documentations, max TX power supported by most Huawei device is 33dbm, you can run up to 33 in most modem.

For the second tweak, it just boost the signal gain of the device which it depends. Some feel it is useful, some feel it is not

Yes, exactly, you need USB driver and it would automatically detected on most Huawei and ZTE models.

I assume most Australian using Sierra device, which need to be in diagnostics mode.

Hi blacktubi, thanks for the reply.

Wow +33dBm. That 2 watts!

Class 1 +21dbm, 125mW

Class 2 +24dbm, 250mW

Class 3 +27dBm, 500mW

Class 4 +33dBm, 2W

In Australia, we have a broad mix of Huawei, ZTE and Sierra 3g and 4G modems.

Modems with external antenna ports are almost universal.

Our current 4G modems are the Sierra 320U, ZTE MF821 (both Telstra) and Huawei E3276 (Optus).

A reliable 3G modem used by many is the ZTE MF668.

I'll take it all away and have a play and see what i can find out about these devices.

Best Regards

John k

can this be used on huawei e398?

Hi there,

Currently Malaysian prefer Huawei thanks to the stability and speed

Sierra tends to overheat here especially 320U.

Cheers

Yes, we've seen that.

Anyone tested stable values for Huawei E1762. I used the recommended ones and my modem wont dial.

And can anyone verify the default values for E1762? Thanks.

856 -100
876 23

why not u try to experiment all the value ?

single channel modem dont over -350,. need to below than that,.

no one can tell you exactly what value is good for your modem in your area though, u need to experiment it yourself

I tried several random values.... All also x boleh pakai... siens... can't dial.

bro....what are value b4 u change...???
