I'm posting this for a friend (Chris).  Please respond to him
 through me (Ted) at TEDI@APPLE.COM.
 
 I am a hobbiest desperately seeking information on how to
obtain or build a tiny portable VHF FM audio receiver.  In my
"research" on the subject, I have obtained hundreds of
schematics for receivers of every kind.  However, I was
surprised to find that the info of was of any help for my little
"pet" project.  I realize that this is a RIDICULOUSLY simple
device but I seem to be getting nowhere fast.
Here are my specs: 
*  Freq Range: 150Mhz-216Mhz
*  Signal: FM audio (mono) 80Khz-20Khz (or as good as possible)
*  FM Modulation: +/- 15Khz
*  Dimensions: Smaller than a deck of cards
*  Power requirements: Able to run 2-4 hours on small batteries
  
 I will need to tune to any one of 5 or so frequencies which I
already know.  Therefore, the device should be crystal
controlled.  This project is basically a simple VHF FM receiver
and I could easily build it myself, if I only had some
schematics to work with.  I can handle the power supply,
amplifiers, antenna and housing. 
 
 I would be very grateful if anybody could provide me with
information/plans or point me in the right direction.  I might
even be willing to make an extra one for you, depending on how
things work out.  Please respond by MAIL to TEDI@APPLE.COM or by
calling me (Chris) collect at 408 522-8373.  Happy Holidays!
