Can I have your radio ? ;-)

[arabbitte]

Hi,

I recently bought a Kaiser. I think it's great. Only thing missing is an FM radio. Or is it?

I think it's accurate to say that the only real difference between the Kaiser and the Polaris is the keyboard. They have the same Qualcomm chipset, same amount of memory, the lot. So why then does the Polaris have an FM radio and the Kaiser does not?

Does anybody know if anybody has attempted to "lift" the radio programs out of the Polaris for testing in the Kaiser?

Most of us are still waiting for the polaris to be officialy released

Kaiser is supposed to be a "Professional" device and FM Radio is not one of it's features.

Does anybody know if anybody has attempted to "lift" the radio programs out of the Polaris for testing in the Kaiser?

This is not possible because it is not only software but mostly hardware issue.

Hey, I'm a "professional" and I want a radio ;-)

>This is not possible because it is not only software but mostly hardware issue.

Ok, but as far as I know the hardware is identical, so this means it should just be missing software.

Hmm..
Just because the chipset and memory is identical, doesnt mean the rest of the hardware is identical.

Anyways.. I think O2's version of the Kaiser has radio. Go check it out.

yeah fm radio require a whole different radio chip compared to gsm
software is not enough to change it so gsm/umts at <800Ghz and are digital start recieving analog signals at around 100Ghz

Ο2 is identical to Kaiser... which means that this was a mistyping error. O2 version does not have FM radio and most sites have corrected their previous posts.

Understood, but do you remember when the Trinity (aka 3600) was updated after launch with GPS? It had GPS all the time, but it wasn't activated on the original models.

I know the Polaris and Kaiser have the same hardware and only appear to differ with the keyboard. So if GPS can be activated on the Trinity, why not FM Radio on the Kaiser?

I'm assuming the FM on the Polaris is not built in to the headset ...

Trinity always had built-in GPS. Kaiser does not have FM Radio built-in. I don't want to disappoint you but this is the truth my friend.

Oh dear :(

This is the first time I heard that there are actually hardware differences that would prevent FM radio functionality from being available on the Kaiser. It sounds like you know what you are talking about - I assumed that the Qualcom chipset that is common to both would mean FM radio was possible on the Kaiser. Does the Polaris have a different or upgraded chipset to the Kaiser or does the FM radio come from additional hardware?

Go on, I can handle the truth (albeit with considerable difficulty ...) ;)

the radio only seem to work when the headset is connected
meaning that it use the headset wire as antenne which mean
that even if the fm radio was in the cpu not having wireing to an
antenna would mean that it could not recieve radio

I think all FM-equipped phones work like this. A friends 3300 has a headset just like my Kaiser. So no problems having to use the supplied headset then.

So, if not in the Qualcomm 7200 and not in the headset, just where is the FM?

[Rudegar]

a phone have more components then it's main cpu and the headset
if you look in the various wiki's for devices where they are opened
it's full of various IC's
if Qualcomm 7200 is not spec'd as having fm radio on Qualcomm's site
htc put another fm radio chip on the pcb to handle the fm radio

fm radio is a pretty old teck so i would understand why Qualcomm would not put too much work into having it on chip

[athanaso77]

Exactly!!! ;)

Look, I know I'm sounding desperate here, but you do say if. I have actually looked at the schematics for the 7200 but there is so much detail, it's impossible for me to see if/where FM radio functionality might be lurking.

So, do we know for a fact that FM radio is not part of the 7200? (Forgive my pedantic questioning - I'm desperate! ;-))

[Rudegar]

cant say 100% but all the techs are listed and fm is not so i would guess another chip is used

you can look in wiki for pcb pics of the other devices with fm to see if you can see a fm chip on any of their pcb's

Why don't you buy this (http://www.expansys.com/p.aspx?i=145554)?

I had a quick look, but didn't see anything. Then again, I'm not an expert ...

Now that some time has passed since the last update in this thread, is anybody out there any more knowlegable about the possibility of an "FM extract" ?

[arabbitte]

I had a look and it's an interesting device, but ...


No screen interface, station selection a bit bit and miss
Bigger than just headphones
I already have a Jabra wireless for car use, so this is overapping functionality
(my biggest issue)It needs it's own seperate power supply for recharging purposes. I'm big into convergence (that's why I bought the Kaiser!) so this is a no no

Now, it's not working. Yet.

Anyone have any comments on the possibility of the Polaris headset having something in it that the Kaiser's doesn't - & thus preventing the FM application from working in Kaiserland?

The thing is, I still find it hard to understand why HTC would change or add to the hardware of the Polaris just to get FM working - especially when the target audience for the 2 devices cannot be that different. Surely there is a big cost to make any mods on a standard platform?

But of course, this could simply be wishfull thinking on my side :confused:
