SPECIFICATIONS Frequency Range: A 100kHz - 300kHz B 300kHz - 1,000kHz C 1MHz - 3.2MHz D 3.0MHz - 10MHz E 10MHz - 35MHz F 32MHz - 150MHz (up to 450MHz on third-harmonics) Frequency Accuracy: ±3% RF Output: 100mV rms Approx. (up to 35MHz) Output Control: HIGH-LOW switch and fine adjuster Modulation:...
Page 5 1. FREQUENCY Dial: Sets the RF output frequency in the range selected by the FREQ RANGE switch. 2. FREQ RANGE Switch: Has six positions for RF output frequency range. 3. XTAL Socket: For insertion of quartz crystal, 1 - 15MHz, in Type HC-6/u holder.

7. AF Output, 1kHz Control settings: Mode switch at INT. MOD. position. FREQ RANGE switch at “F” and frequency dial at 100MHz. Connect the leads from the OUTPUT to the test circuit. potentiometer, 100kW - 1MW, to lower the voltage. 8.
Page 7 3. Modulated Carrier, Internal Source Set the mode switch at INT. MOD. By tuning the receiver to the generator frequency, or vice-versa, an audio tone will be heard in the loudspeaker. An audio voltmeter should be connected across the speaker terminals when aligning the internal circuits. A dummy resistor with suitable power rating can be used in place of the moving coil.
