PRECAUTIONS

1. Replacing the C MOS IC

  • 1. All MOS devices should be stored or transported in materials that are somewhat conductive. MOS devices must not be inserted into conventional plastic "snow" or plastic trays.
  • 2. All MOS devices should be placed on a grounded bench surface and operators should ground themselves prior to handling devices, since a worker can be statically charged with respect to the bench surface.
  • 3. Nylon clothing should not be worn while handling MOS circuits.
  • 4. When lead straightening or hand soldering is necessary, provide ground straps for the apparatus used.
  • 5. Double check test equipment setup for proper polarity of voltage before conducting parametric or functional testing.
  • 6. All unused device inputs shoud be connected to VDD or VSS.
2. Memory Preservation Batteries

Because stations stored in the memory by the FM/AM preset keys would normally be lost when power is turned off or the plug removed from the wall socket, this unit requires two memory preservation batteries to preserve the contents of the memory even when power is turned off. Be sure to insert the correct type of batteries into the battery holder in the bottom of the unit before turning on power for the first time.

3. Voltage Selector (rear panel)

120/220V models are equipped with a voltage selector to conform with local power supplies. Be sure to set this switch to match the voltage of the power supply in your area before turning the power switch on. Voltage is changed by sliding the groove in the switch with a screwdriver or similar instrument to the top or bottom position. Confirm that the switch has been moved all the way up or down before turning the power switch on. If there is no voltage selector switch on the unit you have purchased, it can only be used in areas where the power supply voltage is the same as that of the unit.

4. De-Emphasis Switch (rear panel)

120/220V models are equipped with a 50µsec - 75µsec selector switch. This switch is set to 50µsec at the factory, but may have to be reset 75µsec depending on the area where the unit is used:

  • Europe: 50µsec
  • U.S.A. : 75 µsec
5. AM Tuning Step Frequency Switch (bottom panel)

120/220V models are equipped with a switch to change the AM Tuning step frequency from 9kHz. These units are set to 9kHz at the factory; change to 10kHz if this gives better results in your locality.

2. Control Key Connections

UP, DOWN.....Pressing the UP or DOWN key will cause the frequency to be shifted upward or downward (in 200kHz steps with the D model and in 50 kHz steps with the W/G model). If the key is pressed for more than 0.5 seconds, the frequency will be shifted 50 kHz every 40ms until it is released.

MW, FM, LW.....The MW, FM, LW band switches.

MEMORY.....Pressing this key causes the memory to be placed in the write-enabled state. The frequency displayed will be stored in one of the memories 1—6 if the corresponding memory key is then pressed within 5 seconds. The write-enabled state will be cleared after 5 seconds if none of the memory keys are pressed, or if the AM/FM selector keys are pressed.

M1—M7(M6).....These keys are used to preset and recall the contents of the memory. Positions are provided for keys for reading / writing up to 7 frequencies, but only 6 keys are installed in the T-08. See the paragraph on MEMORY for writing frequencies. Pressing one of the

keys M1—M6 once will cause the contents of the corresponding memory (a frequency) to be read. A muting signal of about 0.45 seconds duration is output at this time.

TPP (Tracking Point Preset).....Switch is used to write adjustment frequencies into preset memory during set production. Not used with the T-08. When the IC Vpp is first inserted, the lowest FM and MW frequency is placed in the memory.

4. FM/AM Selector Circuit

The FM/AM selector circuit is shown in Figure 4. Operation of this circuit is controlled by digit signal D5 and segment output signals Sa and Sg.

For FM reception, both D5 and Sg are "H" (Sa is "L") and output from b of RS-F/F is "H." Since output from c is "L," Q420 is turned ON to light the FM indicator and Q419 is turned OFF. Further, AM operation ceases because Q303 goes ON and Q302 OFF so that B + is not supplied to AM IC Q301. Also, Q206 goes ON, turning Q205 OFF so that the FM signal is output.

For AM reception, both D5 and Sa are "H" (Sg is "L"), output from b of RS-F/F is "L"and that from c is "H" so that all transistors operate in the opposite manner, the AM indicator is lit and the AM signal is output. Further, Q304 goes ON so that B + is supplied to pin 3 of AM IC Q301 to start AM operation. Also, the level at pin 2 of IC Q103 of the FM IF system becomes "H" so that this IC does not operate and output from the 16-pin VCO also ceases.

5. Preset Station Indicator Circuit

(BCD code outputs from Se—Sg)

Fig. 6

Preset station indicator connections are shown in Figure 5. BCD codes are output from segment terminals Se—Sg in synchronization with the timing of digit signal D4. The sequence is shown in the timing chart in Figure 6. The display signal for the "1" in the first digit of the frequency display is output from segment terminals. Sb and Sc at timing T1 of digit signal D4 (blank codes are output from segment terminals Se—Sg at this time). At timing T2, the BCD code

for preset station display is output from segment terminals Se—Sg (at this time, blank codes are output from segment terminals Sa—Sd). Since output is timed as shown in Figure 8, it is replaced with starting output at D—F/F of Q416. This is output as BCD code to the decimal counter to display the frequency.

6. PLL Tuned Circuit

A block diagram of the tuned circuit of the PLL is shown in Figure 13.

Operation During AM Reception

The reception frequency is applied to the programmable divider where it is divided to 1/N and output as fv. This is applied to the phase detector where it is compared with frequency standard fr (9kHz for G/W model and 10 kHz for D model). If fr and fv differ, Eo equal to the difference in frequency is output. Since error output Eo is a pulse waveform, it is passed through the low pass filter to change it into DC voltage VD, which is applied to the variable capacitor in the front end to change the reception frequency. This continues until fv and fr are the same and Eo = 0. (G/W model)

Since AM signals received range from 522 kHz to 1611kHz, they are changed to 972kHz-2061kHz for reception. Furthermore, since fv = fo/N, the divisor, N, is changed by program code input so that N = 972/9-2061/9 = 108-229. (D model)

Since AM signals received range from 530kHz to 1620kHz, they are changed to 980kHz-2070kHz for reception.

Furthermore, since fv = fo/N, the divisor, N, is changed by program code input so that N = 980/10-2070/10 = 98-207. Operation During FM Reception.

The pulse swallow method is used in the prescaler of the T-25. In this type of prescaler, a supplementary number (changed according to the program code input) and the divided reception frequency from the prescaler are combined in the control counter and the prescaler's division factor is switched between 1/16 and 1/17 according to external control (1/17 when the PSC terminal is "H" and 1/16 when it is "L").

The station oscillation frequency is applied to the programmable divider, but the programmable divider has an upper frequency limit of only 30MHz, so the pulse swallow-type prescaler, which can be used up to 150MHz, is inserted for division to 1/Np.

The signal is then divided to 1/2 in the microcomputer and applied to the programmable divider and divided to 1/N. The result is compared with a 25 kHz frequency standard in the phase detector and the error is output as Eo until a match is obtained as in AM operation.

7. Muting Circuit

A muting circuit consisting of a zero cross and IF level detecters is built into IC O103: output of this circuit is from pin 12. R127 is the variable resistor used to set the muting level, and is set so that muting opens at 10dB. When the antenna input level exceeds 10dB, transistor Q802 is turned OFF, Q803 is turned ON, and Q203 and Q204 are turned OFF so that the FM signal is output from the output terminal. Further, this circuit closes muting when a noise element is detected in the output of noise amplifier Q804, Q805. Q801 is ON during AM reception so that all transistors operate in the above manner and the AM signal is output.

When the STATION, BAND (AM/FM), UP or DOWN switches are operated, the pulses shown in Figure 9 are output from pin 8 of O703 and muting is activated Note : The noise amplifier is not used for 120V medel.

Muting switch circuit

Band (89.9 - 76.1MHz, 76.1 - 89.9MHz)

A muting switch circuit is used the flip-flop circuit of multivibrator.

When press the MUT/MODE switch, transistor Q503 is turned OFF, Q504 is turned ON, and FM signal is output so that the Q203 and Q204 transistors operate in the above manner.

O502 is turned ON and MUT L.E.D light off. O501 is OFF during AM reception and MUT L.E.D light off.
