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
