	     Subcarrier	Transmissions Noted in the NY/NJ Area


       On a recent trip	to the northern	New Jersey area, I did some
       subcarrier  listening  by  connecting  the antenna jack of a
       Yaesu FRG7700 receiver to the audio stage of a cheap televi-
       sion set:

	  - By tuning the Yaesu	to 88.0	kHz FM,	and the	TV to chan-
	    nel	 4, WNBC-TV New	York was heard rebroadcasting WYNY-
	    FM audio.  WYNY is an NBC affiliate	station.

	  - By tuning the Yaesu	to 31.5	kHZ  USB,  and	the  TV	 to
	    channel 68,	the audio of WWHT-TV Newark, a scrambled TV
	    station, was monitored.

       Other signals were heard, including  a  series  of  6  or  7
       telemetering tones sent every 30	seconds	on an FM subcarrier
       of a TV station.

       Several FM broadcast stations in	the New	York area were also
       using subcarrier	technology.  One station was transmitting 3
       different subcarrier channels of	information concurrently.
