Soldering

The PCB already contains many soldered-on SMD components (surface-mounted

device): the receiver IC TDA7088, 15 capacitors and one resistor. Only a few of

these components still must be soldered in with connection wires. This includes

all components of the NF ampliﬁer, the coils and components around the radio’s

diode tuning.

The SMD components

Now the PCBs are soldered together. The circuit diagram of the complete receiver

on the last page of this manual serves orientation purposes. For a small solder-

ing course, see the online magazine ELO (www.elo-web.de).

Components on the PCB

Equip the PCB with the electronic components according to the equipment plan.

First install the two coils SP1 and SP2.
