SECTION 1. FEATURES
1. 144/430 M H z , a l l m o d e ( F M , S S B ( U S B , LSB), CW)
transceiver.
8 bit microprocessor controlled VFO and full variety of
auxiliary functions.
F M c i r c u i t r y b a s e d o n K E N W O O D ’ s a d v a n c e d
technology and outstanding SSB quality.
Buit-in VOX.
Buit-in s i d e t o n e a n d C W c i r c u i t r y capable of semi-
break-in Operation.
Adoption of power module in the transmitter final Stage
for dependable Operation on both bands.
2. Built-in digital display that indicates operating frequency
in all modes.
D i g i t a l d i s p l a y e q u i p p e d w i t h e a s y - t o - r e a d g r e e n
Phosphor tubes.
7 - d i g i t d i g i t a l d i s p l a y t h a t d i r e c t l y r e a d s d o w n t o
100 Hz.
Frequency indicator that reads out carrier positions
when mode of Operation is changed.
Two VFO’s (A and BI are built into the transmitter for
more enjoyable Operation such as “Cross-frequency”
Operation.
Buit-in 1 0-channel memory circuit stores operating fre-
quencies and bands. Two channels (CH9 and CH10)
can be called out by using CALL channel switch.
Easy-to-read display indicated 2 VFO’s ( R, b ), memory
channels ( 1 -~8 ) and priority channels ( c and c )
Display function that clears frequency below 1 kHz in
F M - C H .
3. Dependable electrical and mechanical functions
VFO frequencies are switchable in 2 Speeds, SLOW (in
12.5 kHz, FM-CH) and FAST (in 5 kHz, FM-CH).
VFO knob equipped with variable torque mechanism.
Pushbutton band select switched (UP and DOWN) that
shift up and shift down frequency between 144 MHz
and 440 MHz in 12 bands at 1 MHz intervals.
Wide band design for both transmitter and receiver that
eliminates the need for tuning the RF circuits.
Panel layout based on human engineering.
Full variety of indicating functions to check operating
c o n d i t i o n s ( O F F S E T , O N A I R , B U S Y , F . L O C K , R I T ,
F.STEP).
Amplified type AGC and ALC circuits that maintain
receive and transmit Outputs at constant level without
distortion.
4. A multitude of auxiliary functions for more enjoyable
Operation.
The use of RAM memory System enables any given fre-
quencies to be stored in or cleared. (IO memory chan-
nels).
Built-in back-up battery holder to keep data stored at all
times.
Built-in memory scan for selection between 144 MHz
and 430 MHz.
RIT circuit function on VFO, memory channels and
priority channels.
Adoption of frequency lock circuit.
A repeater shift circuit is provided, and the shift width
on the 144 MHz band is - 600 kHz or + 600 kHz, and
that on the 430 MHz band is - 7.6 MHz or - 1.6 MHz,
which may be selected as required. The tone frequency
is 1,750 kHz. In the event of off band, the digital
display goes out and transmission is halted.
K E N W O O D ’ s u n i q u e n o i s e b l a n k e r ( N B ) c i r c u i t t o
eliminate pulse type noise.
Four-function meter serves as S meter, RF meter, ALC
meter and Center meter.
RF power HIGH/LOW selecting function provides conve-
nience in transmission with local stations in FM.
Auxiliary (AUX) socket.
5. Designed for fixed and mobile Station Services.
ACIDC 2-way power Operation.
Equipped with a grip for carrying convenience.
Sufficient AF output power (2.5 W/4
Built-in large sized speaker (7.5 cm). External speaker
connecting jack.
