Message-I

 
 For space saving and cost reasons I would like to use one of 
 those small can oscillators with 4 terminals.  The only 
 problem is how to modulate either the amplitude or the 
 frequency of this device.  I have noticed that varying 
 supply voltage changes both the amplitude and frequency.  Is 
 this the best way?  
  
  I don't have any spec sheets on these oscillators but I have determined
  V+, V-, and the output.  The other pin seems to be no connection.
