Hi,

many of these players use the earphone cables as the antenna. Try using earphones with a l;onger cable, perhaps ...
Cheers,

Seriously? What about players with built in speakers?

aliasjanedoe , The radio wont work without an antenna plugged into it , IE the headphones so built in speakers wont work. Theres a little hack you can do to fix this.

"You open up the player and find the headphone jack , then get a long stips of copper wire you can use for your reciever , Or whatever works best , But copper is often thin so i use it. and you need to wrap it in a small coat of sticky tape to stop electrical shortcuts. Then solder it to one of the headphone pins (Im not sure which one it is) i think its the bottom , just test them out witht eh player turned on.
The player will function fully and there wont be any noticable changes because your antenna is on the inside of the player. If you pop headphones in then it wont affect them either. "

ya without headphones it wont work..
its good idea to attach small wire...
but one thing to ask..FM is nt direction dependent...like AM.
but my fm rex is direction dependent,... wht do u say abt it ?

ritul , the FM demodulator in the these players are of cheap quality, so not as good as those used by big brands like Sony.
So even though FM is not directional dependent, the demodulator is not good enough to demodulate the signal efficiently.
