■ The following parts are required for adjustment
1. Antenna connector adapter
The antenna connector of this transceiver uses an SMA
terminal.
Use an antenna connector adapter [SMA(f) – BNC(f) or
SMA(f) – N(f)] for adjustment. (The adapter is not provided
as an option, so buy a commercially-available one.)
2. Nut wrench
In order to turn the volume nut and the channel selector
nut, use a recommendation tool.
KENWOOD part No.: W05-1123-00
3. Universal connector
Use the interface cable (KPG-36A/36U) for PC tuning or
the lead wire with plug (E30-3287-28) and screw (N08-0535-
08) for panel tuning. Connect the plug to the universal con-
nector of the transceiver and tighten the screw.
The lead wire with plug (E30-3287-28) and screw (N08-
0535-08) terminals are as follows. Numbers are universal
connector terminal numbers.
Caution
1. When connecting the plug to the universal connector of
the transceiver, a short circuit may occur. To prevent this,
be sure to turn the transceiver POWER switch off.
2. Since the RX AF output is a BTL output, there is a DC
component. Isolate this with a capacitor or transformer as
shown in the fi gure.
