  • Page 2: Tuning Procedure

    Tuning procedure Tuning is possible only in the OPR mode. Preliminary Information Tuning the amplifier involves a procedure of matching the impedance of the antenna and transmission line to the tubes characteristic load resistance. This will ensure maximum plate efficiency and RF gain at nominal output power, with minimal distortion and spurious output. Note that REFLECTED POWER readings depend on the antenna and transmission line impedances only, and not on amplifier tuning.
  • Page 3 b. Tuning procedure OM2000A+ has been design to deliver maximum output power at 50 Ohms load. To deliver maximum output to real load you need to adjust the tuning according to your real antenna impedance. We are in the operation mode. Press MENU Now try to press PTT (foot switch for example).
  • Page 4 After adjustment press SAVE for writing values to the memory and press EXIT. Repeat adjustment process for other segments / bands Deviding of bands into segments Band (MHz) 1,8 3,5 7 10 14 18 21 24 28 Width of the segments (kHz) 20 30 50 30 60 60 60 70 TUNING The OM2000A+ amplifier is operated in class AB.
  • Page 5 3. Press PT and increase driver power to 10W (OUTPUT power will be abt. 500W) Please note! If the input power is higher than 15 W and the power amplifier is not correctly tuned, the safety devices will switch to STBY. After switching the amplifier to PTT, the amplifier will automatically reset and switch back to OPR mode after approximately 2 seconds.
