Radio without headset?

[Vinko]

Can we turn the radio function on without inserting the headset? ...

is there any way to use the charger as antena instead of handfree while charging the phone ...

Hi, I think my question has the same idea alhough is somehow different:

I woud like to keep the K750i powered by USB data cable connected to the computer while listen the radio on K750i (throuh speaker) for longer times. The radio on on K750 does not work without headset which is used as radio antenna and you cannot connect USB cable at the same time because both the headset and USB cable share the same connector.

My question is how to make use of the USB kabel as radio antena? Does anybody knows vhich pin/wire on headset cable is used as antenna?
Is it SP REF (speaker common reference, pin-2 on new 12pin SE connector) used as antenna or any other?
Can the GND (pin 9) or other (which?) pin from USB cable be used as the radio antenna and short-connected it to antena pin (pin-2 or other?) in USB cable to phone connector? Provided that this is correct it would also probably require to short pin 8 vith 9 to recognize the USB cable as a headset as the VPPFLASH (pin 8) shorted to GND (pin 9) on headset cable connector for headset recognition.

macril, can you provide info here or on PM how you solved this with your charger?

Anybody has advice or experience with this, or maybe has already tried this?
