2-Tone Test Oscillator |
||||||
A battery powered 700Hz and 1900Hz Test Oscillator, with variable frequency single tone feature, for SSB transmitter adjustment |
||||||
|
||||||
The 2-Tone kit employs DSP techniques to generate low distortion audio tones for transmitter and general communications audio testing. Two modes are offered, Dual Tone with composite 700Hz and 1900Hz outputs and Single Tone with an adjustable frequency from 100Hz to 3500Hz. In both modes output amplitude is adjustable in 1dB steps over a wide range. In Dual Tone mode the amplitude of either tone may be adjusted in 0.1dB steps to compensate for the audio response of the transmitter. The PCB is designed to be a slide fit into a Hammond 1455K1201 extruded aluminium box. Jean-Claude Gerber, HB3YDH, has very kindly provided copies of his drilling templates for the Hammond Enclosure and component value overlay which may be found here; 2-Tone Enclosure Panels, 2-Tone Overlay Values. Thanks Jean-Claude!
