Paragon-III  Technical Manual

1.  For sets with serial numbers following 217262, set RV69 (driver power level) fully clockwise.

2.  For all units, preset the tuning controls as shown in Figure 19

3.  Set RV63 (front panel power control) fully clockwise.
4.  Key on the exciter (press PTT button).
5.  Adjust CV1 for maximum output.
6.  Adjust CV8 for maximum output.
7.  Adjust CV32 for maximum output.
8.  Adjust CV51 and CV57 for maximum output.
9.  Adjust CV34 and CV35 for maximum output.
10.  Recheck all settings. The power output should exceed 110W.
11.  For sets with serial numbers following 217262, adjust RV69 (driver power level) until

the output power drops to 110W.

12.  For all units, adjust RV63 (front panel power control) to reduce the power output to the required

level (normally 100W).

1.  Insert a Shunt current device (HP 34330A Shunt 30A ) between the power supply red wire and

its 13.8Vdc output, then connect the shunt to the multimeter (VDC scale)

2.  While transmitting, monitor the current. It should remain under 22A.

3.  Retune CV32, CV51 and CV57 towards maximum capacitance to obtain minimum supply cur-

rent, but do not exceed a maximum drop of 0.5A per control.

4.  Check that the supply current is  <22A for 100W output power.
