RX Alignment Procedure:

Refer to ALIGNMENT POINTS

Equipment Required
a. RF Signal Generator (27 MHz Band, 50 ohm output impedance)
b- AF SSVM
c. Oscilloscope (For AF Signal)
d. DC Power Supply
e, 8 ohm Load
f. Oscilloscope (0 - 50 MHz)

STEP

ADJUST FOR

1.

Channel: 19
Clarifier center
Volume fully clockwise
RF GAIN fully clockwise
Squelch fully counter clockwise
NB/ANL : off Mode AM

Set the SG on channel 19 27.185 MHz with 1 kHz,30% modulation.
  

 

2

Same as step 1

 Adjust the level of SG to obtain 2V reading on AF SSVM.

L11, L10,
L8, L7,
L6 L5,
L4, and L3

Then adjust coils for maximum reading on AF SSVM. Repeat this step reducing the SG output.

3

Same as step 1

 Same as above

L3

Adjust for max. reading on AF SSVM, Check the sensitivity difference between CH1 and 40. If it is over 1 dB, re-adjust L3 to obtain within 1 dB.

4

Same as step 1
except squelch is fully clockwise.

 Set the level of SG to 1000uV.

VR2

Then adjust so that the AF signal will just appear on Oscilloscope.

5.

Same as step 1

 Set the level of SG to 100uV.

VR1

Then adjust for "S-9" reading on Transceiver's meter.

6

Same as step 1
except NB/ANL switch is ON.

 Connect the Oscilloscope to TP1.

L2

Adjust the level of SG to approx. 1.6uV. Then adjust for max. DC reading.
