Table of DTCS Codes

 
                     
 
 
                     
     
  The table below lists DTCS codes in use..  
         
   
  • 512 codes are possible but not all can be used as this would lead to errors
  • 112 codes are known to be in use
  • 104 codes are available on the IC-R20
  • 52 codes are allocated in the UK under PBR licence, see MPT1381
   
         
         
   
   

 

Polarity can be either normal or inverse. Each normal code is equivalent to a specific inverted tone and vice versa as shown in the table.

Use for PBR is shown in the fourth column. The fifth column shows which group the codes belong to as described in MPT1381. The disallowed codes are shown greyed. Tones not available on the R20 (as denoted in the third column) are shown in darker grey.
