Ge JasHO97686 Wireless Computer To Stereo Transmitter Review

Average Reviews:

(More customer reviews)Both the Amazon product description and the enclosed documentation are short on information about the technology used, so I thought I'd share what I found out.
The unit broadcasts on some FM frequency. When I turned on the receiver without turning on the transmitter, I was getting some FM station, but I didn't track down which one. So this is like an MP3/iPhone FM transmitter you would find in a car, with many of the same characteristics.
Because the units are AC powered, and not limited in size, they can work a little better than the car versions. When I turn on the transmitter, the FM station completely disappeared, so the unit is putting out a good signal. When I had the units about 20 ft apart in line of site, they worked very well. I had to turn the volume up on the receiving end, which indicates they aren't modulating the signal very much. When I tried the usage I really wanted, not so good. Transmitting through a wall added some noise, and walking around near the signal path generated noisy interference. Transmitting from one floor to another generated too much noise.
It may be that providing a line level signal to the transmitter would provide better modulation, but most computers these days only have a headphone output. The signal problems result from using a low power FM frequency, which is probably the only way they can provide this functionality for such a low price. (Be sure to follow the instructions to have the two antennas parallel as this polarization makes a big difference for FM signals.)
The product basically works as advertised. It has limited (unspecified) range, and really wants line of sight, so the range drops dramatically through a wall. The music quality at its best is typical of low power FM transmitters. The nice thing about it is that it's so cheap that it may be worth a try if you need to remote some music. But don't count on it.
