  13.          A few weeks ago, I posed a question about listening  to
  14.          SCA  transmissions on the FM commercial broadcast band.
  15.          An article in Monitoring_Times claimed that  connecting
  16.          a vlf receiver to an FM broadcast receiver would permit
  17.          SCA detection.
  18.  
  19.          Necessity being the mother  of  invention,  a  way  was
  20.          found  to  confuse  the ICOM R71A into tuning below 100
  21.          kHz1, and after receiving substantial inspiration  from
  22.          Will  Martin,  Phil  Karn,  and others I now can report
  23.          success!
