High Performance 2 m Transverter

Several  decades  of  engineering  and  production  of  Transverters  result  in  this  new  designed  high 
performance  Transverter  TR  144  H  +40.  Its  outstanding  technical  data  make  it  usable  for  many 
applications.  The  transverter  was  originally  designed  for  VHF  amateur  radio  applications,  for  example 
high performance contest stations. The receive path of the transverter provides very good large-signal 
performance. The new design of our transverter for 144 MHz features better performance and many new 
functions.

Now,  an  external  10  MHz  reference 
frequency  can  be  connected  to  achieve 
highest  frequency  accuracy.  This  is 
necessary  for  EME  and  WSJT.  The 
frequency  of  10  MHz can be supplied by  a 
highly  stable  OCXO,  a  reference  oscillator 
of  a  frequency  counter,  a  rubidium 
frequency  standard  or  a  GPS  controlled 
frequency source.

The  new  design  includes  the  “old”  options  02  (TX  IF  input  power  60...1000  µW  /  0...-12  dBm)  and  06 
(common IF-connector for RX/TX). So the Transverter is compatible to most of the used HF transceivers 
with transverter output. The TX IF input ranges and the IF connector configuration can be done with the 
internal  switches  of  the  transverter.  The  “old”  option  04  (drive  gain  control  on  the  front  panel)  is 
standard now.
