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.pdfClass 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.
