Computer to FM transmitter (part 2)

In an earlier post, I mentioned that I am looking for a computer to FM

transmitter. I decided to get a portable FM transmitter with an audio

input instead.

After posting to various mailing list, I got a lead that there is a

store in Jakarta that sells such as device. I went to the store,

Wasabi Gadget. Sure enough, they have an Arkon Sound Feeder SF 150.

This little device takes an audio input and broadcast it in FM between

88-95 MHz. I bought the device.

I turned out this device only works in a short distance. In my first

experiment, I plugged this device into my notebook (running winamp)

and put it close to an FM receiver. I could listen the song in the

radio. I then moved the notebook away from the radio. The quality of

the signal faded away. Three (3) meters was the maximum distance. I

tested again with another FM receiver. This time it was even worse. It

faded quickly. 30 cm was the maximum distance.

My original idea was to broadcast around the house, or at least 10 or

15 meters. Perhaps FCC regulation forces it to limit the power? I

don't know. But this is not what I want. Although it is still usable,

since I have two (good) boomboxex without line in. I could use this

device to feed sound to the boombox. Of course, the distance has to be

really close.

Another problem is the frequency range. Recently, there was a

frequency reorganization(?) in my city. The frequency of some FM

stations were relocated. They were pushed to the "left side", which is

the range of my sound feeder. So it was difficult to find an empty

frequency.

In any case, I am still looking for a computer to FM transmitter which
