 RECOMMENDED ASSEMBLY SEQUENCE

 

 

All SMD parts soldered at the factory. You don't have to solder anything SMD 

 
Based on your experience you can place the components in the order you are used to. 
However I can recommend the following assembly sequence: 
 

  Place and solder D1 10V zener diode. 

  Insert and solder all resistors 

  Insert  and  solder  the  other  eight  diodes  (1N4148) 

all  printed  “D”  on  PCB.  They  are  all  placed 

vertically (see the images).  

  Insert  and  solder  all  shielded  coils  (make  sure  they  lie  flat  on  the  board).  L1  to  L4  are  5u3H 

marked 34. L5 and L6 are 1u2H marked 35. 

  Insert and solder toroids (see section 

“TOROIDS WINDNG”). 

  Place and solder all relays. RL1, RL2 RL3 have a printed line that has to match the one printed 

on the board (see the images). 

  Place and solder BNC antenna socket. 

  To finish, solder the pins strips. This is important work. See the section 

“wiring and connections” 

  All capacitors are SMD format and are soldered in bottom PCB by
