TK-3212L

Test Equipment Required for Alignment

Test Equipment
1. Standard Signal Generator
(SSG)
2. Power Meter
3. Deviation Meter
4. Digital Volt Meter
(DVM)
5. Oscilloscope
6. High Sensitivity
Frequency Counter
7. Ammeter
8. AF Volt Meter
(AF VTVM)
9. Audio Generator (AG)
10. Distortion Meter
11. Spectrum Analyzer
12. Tracking Generator
13. 8Ω Dummy Load
14. Regulated Power Supply
■ 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. Repair Jig (Chassis)
Use jig (part No.: A10-4086-03) for repairing the transceiver.
Place the TX-RX unit on the jig and fit it with screws.
The jig facilitates the voltage check and protects the final
amplifier FET when the voltage on the flow side of the TX-RX
unit is checked during repairs.
3. Nut wrench
In order to turn the volume nut and the channel selector
nut, use a recommendation tool.
KENWOOD part No. : W05-1012-00

Major Specifications
Connect the power cable properly between the battery jig
installed in the transceiver and the power supply, and be sure
output voltage and the power supply polarity prior to switching
the power supply ON, otherwise over voltage and reverse
connection may damage the transceiver, or the power supply
or both.
Note: When using the battery jig, you must measure the
voltage at the terminals of the battery jig. Otherwise, a slight
voltage drop may occur within the power cable, between the
power supply and the battery jig, especially while the
transceiver transmits.
