I had a problem about BT droping when i was transfering file over it after 1MB +-200kB the transfer droped. So i started shuting down running programs and i found out the the XCPUSCALAR was killing BT i had AUTO SCALE WITH CPU LOAD turned on.
Any 1 had this problem like me ? :shock: :lol:
Hmm.. nope. Never happened with me. Did it work again properly when you disabled the Auto CPU load?
did not tested yet ... i'll try and let u know :wink:
EDIT: no problems if AUTO SCALE turned off :lol:
i had these setting set on auto scale:
0-20% 200MHz
21-50% 400MHz
51-70% 530 MHz
71 - 100% 530 MHz
Hi,
Is it possible to change FM band to receive 108 Mhz to 133 Mhz ? ( Change the Diamond FM Radio' s wave band/scan range/spectrum ?)
HTC TOUCH DIAMOND
ROM : 1.93.401.2 WWE
Radio : 1.00.25.07

Why would you like to do that?
>FM radio frequencies are Airborne frequencies and they are amplitude modulated i.e AM.
You are right. I'd like to listen Airborn frequencies. Is it possible with Diamond ?
Id actually like to know if it is possible as well, alot of cool frequincies in that range, airtraffic, police, firestation... would be cool to be able to use the diamond as a frequency scanner as well
AM or SSB or PM are different moduleation forms then fm
am is amplitude modulated
ssb is single side band == only info in ½ the am "sinus"
pm is pherse modulated
fm is frequency modulated
they cant recieve signals from other modulations
and unless a fm radio was made to recieve from other ranges
it's impossible to change it
with old type of radios one can change the components
called crystals to match other hz's but if it's inside a chip it's not possible
Ok , but airtraffic comunications are FM (108 to 133 mhz). Is it possible to set Diamond to FM Band 108 mhz / 133 mhz ??? I know ... it is possible to change a normal FM receiver to listen 108 Mhz to 133 Mhz instead 88 mhz to 108 Mhz ...
Do you know if it is possible ???? Thanks.
i cant say but i doubt it
Radio Frequency change
Actually, the radios in most current PDA / Cellphones are run by software -hence, for example the RADIO software in the boot rom being different based on the version number - causing different battery drains, lock-on time for GPS, etc.
What is needed is a set of spec sheets for the hardware inside the phone and then an "expert software" package to disassemble and label the code within the Radio software. These can sometimes be provided by the hardware manufacturer - not the phone/PDA manufacturer - but Intel, Motorola or other such.
After that, if the timers and registers can be reset to different frequencies (it is all done by 'countdown' timers and dividers) then yes, the radio CAN be changed to cover different frequencies - such as Aircraft bands.
And, yes, I know this because I have designed microcode for such devices before - but I got out of the business because it has become too, too demanding on an older gentleman such as myself.
yes i made a ssb radio in a dsp once as a project but even if it's software
it dont change what range of Hz's one can recieve
the first filters in the line before the dsp get to "play" with the signal
set the limit of what range is possible
that being said i dont know for suden what the max range the chip in
the diamond
but few companys who want to make money spend alot of money on hardware
which is able to give more then they need in terms of range and the likes

In digital radios, even the inline filters are digital, and most (like cellphones) have a large set of dividers and multipliers in the head end, the base frequency on many of the phones is 2.3 GHz and then that is frequency multiplied or divided to get to a harmonic of the frequency wanted, and after applying digital bandpass, hipass and lopass filters to chomp out the "grass" they end up with the frequencies wanted. Most all of that is done inside a single chip these days - they don't use DSPs much anymore - they have complete head end, intermediate, FM/AM/FSK/SB and DV outputs right from the single chip now. (I really did do this carp for a living, guys.... )
Dont forget that MOST ot the PDA/Cellphone users are blind to even the idea that the thing is completely built with software - they just "take it as it is". If you think about the MILLIONS of users out there with HTC products in thier hands and how FEW are really in this forum, it doesnt take much to see that the companies are pretty safe about making money - not to mention that they bring out new bells and gadgets every 12 to 18 months too, just to keep the money rolling in!

to be able to sample a signal one is required to according to nyquist
to use at least 2 times the hz as the signal you are sampling
with the dsp i used ADSP 8150 EZ-Kit Light board
i had a 300Mhz dsp and samping Mhz or even 1XXKhz signal would
be imposible without a pre downsampling system analog or asic

Yuppers.... an ASIC is only one segment of the headend inside the primary radio chip. Current ASIC's can take a 2.3GHz input and create a reference from 40MHz up to 18GHz with a max of 8dbm insertion loss to the secondary segments. From there, you can probably guess what can be done - since the reference is 40MHz to 20GHz, then changing the operating radio band and the bandwidth is just a matter of changing the preload values in 10 or 12 downcounter registers, setting the ouptut format and channeling the analog to the proper device(s) -
I was a subroutine programmer for some military development work which used a Freescale MXC300-30 (modified for the particular use) and I tell you, the things that chip could do..... holybejeezus!!!!
The master clock was 600MHz but it could handle WDCMA Tri-band to 1900 MHz [1.9GHz] while handling the audio and video conversions (much slower clock rates - 128 KHz and 1.75 MHz) and do this all at the same time as it was providing the master processor clock and a few other things as well.
Ah well... those days are over (thank God!)
hey everybody!
is there any way to make the wizard faster?
do you know any good programm for it?
or is there a possebilety to use another cpu? but that would be hard work and i have to know a lot about that then right?
so yea? is there just any way to make the pda faster?
i have windows mobile 6.1
thanks
Overclocking 8125/Wizard
well, honestly, There is no possible way to exchange the processor in the Wizard, However you can you a old program for windows mobile phones called "Omap clock" This will allow you to overclock the Wizard from 195 MHz to 240 MHz or so, not a super difference in speed but to me it makes the difference between using the device, or just upgrading to another. After i found this site ill never get rid of my G3 Wiza 100.
Hi, I don't know about phones, but on PC we have ram speed like 1666mhz, 800mhz and so on. So, what's the ram speed of the SGS?
I read somewhere, the minimum speed needed to fully utilise the 90mil/thread of our GPU is 10mb/s of ram speed? Correct me if I am wrong.
Thanks.
Recently I found this overclocking util:

I'm just wondering what are the highest stable speeds you guys get on your Diamond?
I am testing it with 710 Mhz (37 CPU speed value) and it seems to run stable. 748 Mhz (39) will immediately freeze the phone. This is tested on Speed ROM build 303 (called PHOENIX project now)
