Page 5: General Information
(a DC logic signal) exits the receiver on another wire making it impossible to carry both the audio and the COR on the same audio pair. The PTG-10 converts the COR signal to a tone which is mixed with the audio from the receiver, removing the need for a COR line. The PTG-10 works by injecting a pilot tone on the audio line whenever the associated receiver is squelched, and removes the tone whenever the receiver is unsquelched. -
Page 6: Circuitry And Block Diagrams
Please refer to Figure 5-4. The PTG-10 enables two conductors to carry both an audio signal and a COR signal. The PTG-10 can also function as a line proving tone to insure the integrity of the audio link. The tone produced by the PTG-10 will be notched out in the voter. Two LEDs allow status monitoring. - Page 7 PTG-10 Operations Manual rejection that a balanced link provides is not needed on the input signal. In contrast, the unit’s audio output is balanced, as the output is likely to be sent over a long distance. Table 1-1 SPECIFICATIONS Electrical...

If it is necessary to return the equipment to the manufacturer, a Returned Material Authorization (RMA) number must first be obtained from JPS. This number must be noted on the outside of the packing carton and on all accompanying documents. When packing the unit for reshipment, it is best to use the original packaging for the unit;... -

(0) will produce a 2175 Hz tone; position (1) will produce a 1950 Hz tone. 2.7.2 Potentiometer Adjustments The PTG-10 has two factory set potentiometers. See Figure 2-1. “Overall Adjust” (R8) is set so that a -10 dBm input will produce a 0 dBm output. “Pilot Adjust” (R4) is also set for 0 dBm output. -

The unit is factory set for the audio input level from the receiver to be -10 dBm and the audio output level of the PTG-10 to be 0 dBm. The PTG-10 is also factory set for the pilot tone level to be 0 dBm. - Page 13 PTG-10 Operations Manual 6.84 5.24 2.50 1.25 0.63 1.19 NOTES: A. 19" RACK MOUNT SLOTS (.45 X .25 DIA.) B.
