TUNING 

 

The  amplifier is operated in class AB. Thus it’s possible to obtain a maximum output power 
at an excellent linearity. For this purpose the amplifier has to be tuned carefully. 
The operation of a mistuned PA will cause malfunctions, the increase of grid current (the GRID-MAX-
LED will light up) and problems with TVI/BCI.  
                                                                                                                          
IM-products will be rapidly increased. If a value of + 50mA is exceeded, the safety devices will switch 
the amplifier to STBY mode. 

 

Please note:  
Before starting tuning you have to check if the right antenna or a 50 Ohms 
load resistance is connected at the antenna output! 

  

 

 

Tuning the amplifier to an output of 1500 W  

 
OM2000A will tune automatically to either TRX frequency via CAT interface or by frequency sampled 
by PA. 
                                                                                                                         
   1 . Reduce the power output of your transceiver to the 

0. 

   2. Switch 

OPR/STBY

 to „

OPR“ 

position ( touch STBY )
