[General Topics] DOMin8or:
In germany the police sends there radio on 85-88 mhz.

after changing band to japan in the radio app, or in the

registry

[HKEY_LOCAL_MACHINE\Software\HTC\FMRadio\FMPlayer] "Band"=dword:00000001

it is possible to hear the fire departements and the police. :-)

=============================================

but when the police isn`t sending, a very loud noise is hearable.

now my wish or idea.

a coder can program a little tool,

-that will first automaticly switch the registrykey to japanband.

(and after closing program, switch back to german music radio band 88-108),

-that will get the signal level (rx strenght),

-that will automaticly enable touch scroll wheel. "SupportWheel"=dword:00000001

is the signal level under an optional value, the sound will muted or reduced to 10%.

the RX signal level can get on different ways. by talking with radio application functions.

(i dont have any knowledge about microsofts support for radio app developement.)

by reading the applications ram and find the adress who the radio app stores this info in.

or by hacking the radio app (exe), and hook the signal meter application to the own one, by

simply replace MOVE command (or anything else) with JSR to own programm code, first command is the replaced,

so the command will regulary proceed, stack variables,then use the now avalaible stolen value to

the SQUELCH part of the own SQUELCH programsequence, next the SQUELCH APP will compare the value with user

defined treshold. in case of this it will switch or fast softfade to

user defined min and max volume level.unstack.then RTS return from subroutine to main programm.

this is not the best way.

the better way is, to win coders, they are interested in hearing the police by there own :-)

here some ideas for a complete own policescan software :-)

funktions for a nice police scan tool:

- ~5 numeric input fields for favourite frequenzies,and quick select button.

- automatic band switch to japan band (reg key value changing)

2 volume sliders. (slider one) output volme standart, (slider2) for squelch active volume(quiet).

- squelch, automatic noise reduction on signallevel lost (slider2).

- autoscan.(frequncies/favorites) this will scan/switch the valued favourite channels, as fast as possible.

so we have our ears into ~5? channels a second :-)

autoscan, restart scan delay. scan after (0,1-5 sek) no signal (slider 3)

record function (button), squelch controlled. no signal, no record. :-) (but record is illegal)

(no one can hear 24h a day :-) and the most time it is nothing to hear. so you can hear

it like pod-cast, when ever you want :-) but dont show it to others. thats illegal :-))

an optical (analog/digital/numeric) signal levelmeter, to find the best receiving position.

user optional parameters for frequency scan function:

scan step, 0.01 mhz, 0.05 mhz, 0.1 mhz, user defined

start frequency, end frequency

time to stay/hear on each frequency. (as fast as possible but stop at signal level $X(squelch level),10 ms,50ms,100ms,500ms,1000ms)

and it would be good to set the hardware ZF filter from fm-wide to fm-narrow. but i dont know

if this is possible by commands or hacks. fm-narrow filter is more radio sensitive.

the police will send in narrow band and the music radio will send fm-wide band.

(but narrow and wide filters normaly are electronic circuits.but today the total integrety of

microdevices, will have nice side effects. the ultra compact thinfilm circuit designs offering a lot of hidden

funktions, to use this in other products without redesigning circuit layouts of little helpers, like radio receiver.

good example is the gps function upgrade to a few htc devices, only by software.

and when the hardware design of the fm-radio is good enogh, they can use this little part of elektronik in a lot

of new generations of new devices.so they can use the same driver at all time for maximum compatibility.

good for faster developing the more interesting things. so they plan from the beginning a

radio module with maximum capabillitys. but they use it not at all.

for example, the rds hardware capabilitys. how knows, next time a tool or a radio update will come,

that will read tmc data and broadcast this over a virtual comport to tomtom oder igo.

this can be done by software only. because the fm-radio module is planned in the past to do this in wiiide future)

to set it hardware based to narrow, will increase the sensitivity and clearity, dramaticly :-)

but i can imagine, that a software filter, a low pass filter could help to increase the

subjective hear feeling. but this can be done theoreticly with the HTC audioverbesserung/equalizer.

but only theoreticly. the audio signal from the standart radio application is not mapped

over the HTC audioverbesserung tool. this will have no function.

Switchable button low pass filter on/off

and last, but not least,.... :-)))) an shout cast audioserver, to share what you hear :-)

and the things i forgot :-)

BEST REGARDS,
