COMMON TRANSMITTER SET-UP INSTRUCTIONS
‘A. Connect counter (11) to the output of the 30dB attenuator (8) and set the
Fl warp control, L301A, to the nominal crystal frequency +100 Hz.
B. Conducted spurious emissions measurement. Tune band reject filter (14) |
so that the carrier is not notched and set the spectrum analyzer (9) carrier
indication to the OdB reference line. Tune the band reject filter to
attenuate the carrier at least 30dB. In the MCU-30 all harmonics should
be 59dB or more lower than the reference, in the MCU-15 56dB.
C. Deviation-adjustment
TP-14-154
:
1. Connect audio generator (6) to microphone input. Set the generator: :
for 1 KHz at 1 VAC. Connect the deviation meter (10) to the |
attenuator (9) output. |
2. Key the transmitter and adjust R328 for +5 KHz deviation as measured
on the meter.
D. Check the modulation sensitivity by reducing the audio generator output
until the deviation is +3 KHz. The measured generator output on the AC
VTVM (5) should be less than 20mv rms.
E. On 4 ¢channel models reconnect the counter (11) to attenuator (8). Insert
the crystal in each channel. All channels must be capable of being
‘warped on frequency +100 Hz. Repeat C.1 and monitor deviation meter
(10) on each channel. Deviation should be +4.5 KHz, +500 Hz.
F. Crystal heater circuit check. At room temperature (25°C or 72°F) the
‘voltage at the collector of 0307 should be no lower than 13.0V. When
RT301 is cooled below 0 C(32 F) and when DC power is initially applied
to the transceiver the collector should drop to a maximum voltage of
7 VDC as measured on VTVM (2). |
