wire from K1 in the opening of the rf-bulkhead socket’s core conductor. Fill the hole with solder.
Hint: Screw a PL259 Plug at the outside to avoid deformation of the socket’s insulation caused by the
soldering heat.
Attention: when inserting and soldering the wires into the the pcb pad make sure to avoid a shortcut of
the wire ends with the bottom of the metal box.
The outer conductor of the „TO ANTENNA“
SO259 Socket is firmly screwed and connected
with the metal box. Wire and solder the core
conductor of the SO259 jack with Pad K5 on the
pcb.
The connection between the isolated „Remote
OFF“ RCA Phono-Plug and the pcb is done by a
2-pole pin header (K4). Use short pieces of
red/black litz wire to connect the RCA Socket
with the 2-pole female connector and plug it to
the pin header (K4). Take care of the correct
polarity: plus (red) should connect to the inner
conductor and minus (black) must connect to
the braid/outer conductor.
For the DC supply cable you are best advised to use red/black colored twin strand wire. Feed the cable
through the rubber bushing. Connect the cable with the 2-pole screw terminal (K3). Take care of the
correct polarity: connect the red wire of the cable with the Plus clamp and the black wire with the minus
clamp. DC supply voltage is 12V nominal (10V – 18V possible).
