 I bought 10 (minimum order) FM steroe tranmitter chips. Since I only
 need a few, I would like to sale the rest to any one interested. The
 chip is a BA1404 which integrates the 38kc oscillator (crystal not 
 included), left/right channel amplifiers, sample and pilot circuits,
 FM frequency generator (88-108 MC) and the RF output stage, a nice
 small IC that does all you need to transmit stereo signals within
 short distances. I plan to use it to transmit CD sound to my receiver
 so I don't have to walk across the room to load/unload. Also
 I could play my electronic key board and hear it from FM receiver.
 Send e-mail to me if you are interested; the chip is $1.75 and you
 pay the shipping. 
  
  Also, can anybody tell me where I can buy 38 kHz crystals or resonators?
