ALIGNMENT OF TAPE SPEED
1. Insart 3kHz (MTT-1 11) standard taat tape and set the unit at play mods.
2. Connect the Wow and Flutter Metar to apaaker output.
3. Turn the spaad adjustment screw to get 3000 t30 Hz.
ALIGNMENT OF HEAD AZIMUTH
1. Insert a10kHz (MTT255J) standard teat and set the unit in play mode.
2. Tune the azimuth adjusting screw until you obtain maximum reading for
both channel on the VTVM.

The illustration above is abiock diagram which is afunda-
mental PLL frequency synthesizer.
In order to obtain reference frequency fr, the frequency of
4.5 MHZ generated from acrystal oscillator (OSC) is passed
into adivider circuit of 1/d.
This fris compared with fr’, and runs through phase detector
(PD) and low pass filter (LPF) to be inverted to direct-current
signal, which is then applied as varicap voltage of voltage
control oscillator (VCO), thereby controlling the oscillation
frequency.
This oscillation frequency fout is divided down to 1/N by
programmable divider (PD), so that one closed loop is fixed in
the relation of
fout =frxN
therefore, the operation of PLL is stabilized.
In case of automatic channel selection, the dividing ratio Nis
altered by the PD by acommand from controller, and fout is
changed accordingly.
Programmable dividar
Since the oscillation frequency of VCO is very high as com-
pared with fr, it is divided down to 1/N (in the case of MW)
to decrease the difference from fr in this circuit.
Phasa datactor
This is acircuit to detect the difference in frequency and phase
between reference frequency fr and comparison frequency fr’
in terms of pulses.
Low pass filter
This circuit is intended to vary and fix the output voltage in
order to deliver avaricap voltage necessary for desired VCO
frequency, on the basis of the output of the phase detector.
Prescaler
The local oscillation frequency in FM is higher than the
operating speed of the programmable divider of PLL, thereby
opposing to accurate operation. To avoid this, the local
oscillation frequency is preliminarily divided down in this
circuit to aproper frequency permitting reliable operation of
the programmable divider.
Pulse swallow count system is employed. Acouple of pro-
grammable divider (swallow counter and programmable
counter) can be selected.

The prescaler at first starts the frequency division with the
ratio M+1. Then the swallow counter and the programmable
counter starts counting simultaneously. When N1inputs are
applied, the swallow counter stops counting. Then the fre-
quency division ratio of the prescaler is switched to M.
Programmable counter continues to count and stops when
the input reaches N2. The frequency division ratio of the
prescaler switches back to M+1and swallow counter and the —
programmable counter start to count again.
FM reception employs the pulse swallow count system. MW
raception does not employ the pulse swallow count system
but employs the direct frequency division system and so only
programmable counter is operated.
2. GENERAL DESCRIPTION OF LOGIC IC (lC501 )
a) IC801 LC7232-8424
This IC includes PLL and controller is aC-MOS LSI for digital
tuning of FM/MW PLL frequency synthesizer system and
controls such functions as FM/MW automatic channel selec-
tions, preset memory and frequency digital display driver. It is
packed in a80-pin flat package.
3. AUTOSTOP
If counter start, when high level signal is applied to SD terminal
(Q504 base). Then IF frequency became 10.7MHz +30kHz at
FM or 450kHz*3kHz at MW. When SD and IF is agreed radio
auto search tuning stops.
