Introduction 

 
The 

Bandmaster III

 universal band decoder is a highly integrated unit that not only decodes band 

information using 

YAESU

 “band data” (

note 1

), but can sense band information for all bands from 

160M  through  6M,  including  160M,  separate  80M  and  75M,  60M,  WARC  bands  and  6M  by 
monitoring 

CAT 

(

note  2

)  data  going  to  and  from  the  radio.  The 

Bandmaster

 

III

  also  contains  all 

circuitry for level conversion thus eliminating the need for a separate 

CAT 

radio interface (

note 3

). 

 
It supports radios from 

ICOM

KENWOOD

YAESU

 as well as other radios like the Elecraft 

K3

 or 

TENTEC

 

ORION

  using  CAT  protocols  from  these manufacturers  (

note  4

).  You  can  even  use  the 

decoder as a stand-alone unit where it will monitor the 

CAT 

commands, 

YAESU

 “band data” (

note 

1

) or 

ICOM CI-V 

 data from the radio and automatically switch to the band being used at that time 

by  the  radio  and  this  without  any  computers  attached  to  the 

Bandmaster  III 

  or  the  radio!  Or  it 

can be connected to your computer and used with your favorite logging or radio control program 
as  your  CAT  interface  or  level  converter,  thus  replacing  your  existing  converter  (

note  3

)  and 

antenna selector. 
 
Using  the 

Bandmaster

 

III

  software  you  will  also  have  the  ability  to  configure  the  radio  interface 

and set the frequency limits for each band, thus providing even a great deal more flexibility. The 

Bandmaster

 

III

 gives you two separate relay contact outputs for each band. One set of contacts 

(The  B  contacts)  switch  to  ground  when  activated  and  the  other  set  (A)  is  switched  to  a 
"Common"  pin(13).  This  "Common"  pin may  be  connected  to  ground  or  any  voltage  source  you 
desire. 

 
 
 
 
 
 
 
 
 
 
 
 
 

Note 1:

T

ransceiver, CAT is used to control your radio via computer based software, these are 

often stand alone software or can be integrated into logging software and/or satellite control software.  
Note 3: 

ICOM

 CT-17 or 

YAESU

 FIF-232 or the 

KENWOOD

 IF10a/IF-232C. 

Note 4: The 

K2

 uses 

KENWOOD

 protocol and some of the 

TENTEC

 emulates an 

ICOM

 IC-735, the K3 produces Yaesu 

Band-data.
