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:
