	          QUOTREK STOCK MARKET QUOTES TRANSMITTED	
                            ON FM SUBCARRIERS

       QuoTrek is a subscription service in which stock	quotes	are
       transmitted,  without  the  standard 15 minute delay, on	the
       subcarriers of commercial FM broadcast stations.	 Dataspeed,
       Incorporated provides this service, in which subscribers	use
       a portable radio	terminal,  resembling  a  combination  Sony
       Watchman	 TV/pocket  calculator,	to receive up-to-the-minute
       stock market prices.

       With expansion planned  to  other  cities,  Dataspeed  sales
       literature  claims that QuoTrek digital stock information is
       currently transmitted on	a subcarrier by	these stations:
