cians familiar with similar types of commercial grade commu-
nications equipment. It contains all required service informa-
tion for the equipment and is current as of the publication
date. Changes which may occur after publication are covered
by either Service Bulletins or Manual Revisions. These are
issued as required.
ORDERING REPLACEMENT PARTS
When ordering replacement parts or equipment informa-
tion, the full part identification number should be included.
This applies to all parts : components, kits, or chassis. If the
part number is not known, include the chassis or kit number
of which it is a part, and a sufficient description of the re-
quired component for proper identification.

CIRCUIT DESCRIPTION
1. PLL Frequency Synthesizer
The frequency synthesizer consists of the VCXO (X1),
VCO (L800), PLL IC (IC5) and buffer amplifiers. The VCXO
generates a 16.8MHz signal. The frequency stability is within
±2.0ppm (temperature range of –30 to +60°C).
The frequency tuning and modulation of the VCXO are
done to apply a voltage to pin 1 of the VCXO. The output of
the VCXO is applied to pin 9 of the PLL IC.
The VCO of the TK-290 covers the 38MHz spread, setting
frequencies in r1, r2 (receive) and t1, t2 (transmit) with a bias
voltage applied to the –V terminal of the VCO.
A zero (0) volt bias is applied at frequencies lower than r1,
t1. Frequencies r1, t1 through r2, t2 are biased with –3 volts.
Frequencies higher than r2, t2 are biased with –6 volts, and at
174MHz to 178MHz are biased with –9 volts.
The relation of VCO frequency versus PLL lock voltage is
shown in Figure 2.
The output of the VCO is amplified by the buffer amplifier
(Q14) and doubled by Q3, and is then routed to pin 6 of the
PLL IC. The output of the VCO is also amplified by the buffer
amplifier (Q5) and is routed to the next stage according to the
T/R switch (D602, D603).
The PLL IC consists of a prescaler, fractional divider, refer-
ence divider, phase comparator and charge pump. This PLL
IC is a fractional-N type synthesizer and performs in the 80 or
100kHz reference signal which is one eighth of the channel
step (2.5 or 3.125 kHz). The input signal from pin 6 of the PLL
IC is divided down to 80 or 100kHz and compared at the
phase comparator. The pulsed output signal of the phase
comparator is applied to the charge pump and transformed
into a DC signal in the loop filter (LPF). The DC signal is ap-
plied to pin 4 of the VCO and is locked to keep the VCO fre-
quency constant.
PLL data is output from DT (pin 85), CLK (pin 84) and LE
(pin 93) of the microprocessor (IC406). The data is input to
the PLL IC when the channel is changed or when transmis-
sion is changed to reception and vice versa. A PLL lock con-
dition is always monitored by pin 30 (UL) of the microproces-
sor. When the PLL is unlocked, the UL goes low.

■The following parts are required for adjustment
1. Antenna connector adapter
The antenna connector of this radio uses an SMA termi-
nal.
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.)
Note
When the antenna connector adapter touches the knob,
draw out the knob to mount the connector.
2. Universal connector
Use the interface cable (KPG-36) 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 connector of
the radio 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 radio, a short circuit may occur. To provent this, be
sure to turn the radio POWER switch off.
2. Since the RX AF output is a BTL output, there is a DC com-
ponent. Isolate this with a capacitor or transformer as
shown in the figure.
3. Do not connct an instrument between red or black and
GND.

Repair Jig (Chassis)
Use jig (part No.: A10-1399-03) for repairing the trans-
ceiver Place the TX-RX unit on the jig and fit it with 7 screws.

Panel Test Mode
This mode is used for making transceiver connection tests
and clearing the memory.
To set Panel test mode, turn on the power with [Tone 2]
and [PTT] are still held down and then first release [PTT]. This
mode cannot be set when disabled with the FPU.
In Panel test mode, when channel or signaling is selected,
the signaling that was most recently used is displayed.
Key operations in Panel test mode are as follows.
[Selector switch] : Use to select the test channel.
[PTT] : For transmit.
[SW A] : For down signaling.
[SW B] : For up signalling.
[Tone 1] : For setting Panel tuning mode.
[Tone 2] : For switching power between Hi/Low.
Enter the LCD all lamp mode if held
down for 1 second.
[Monitor] : For monitoring.
[Toggle] : No function.

How to Remove the Flat Cable
1. Gently draw out both sides of the connector lever uni-

(CN101, CN400)
2. Gently rise up the connector lever in the direction of the
arrow with a fine regular screwdriver or tweezers.
(CN1, CN3, CN401, CN403)
Note: Gently push both sides of the connector lever, when
put in the flat cable.
