32. On the SYNTHESIZER, tweak the MAX PWR pot (R74) so that the reverse output power reads 10 Watts as
indicated by the Bird WATT METER.
33. Turn the front panel METER SELECT knob to REVERSE POWER.
34. On the FRONT PANEL CONTROL & METER board, tweak the REV PWR pot (R49) to correlate the front panel
METER (using WATTS scale) to the WATT METER connected to the ANTENNA connector.
35. On the SYNTHESIZER, tweak the MAX PWR pot (R74) fully counter-clockwise.
36. Put the TRANSMIT/STANDBY switch in the “STANDBY” position.
37. Remove the SYNTHESIZER P2 jumper from the RP position and put the jumper in the FP position.
38. On the FRONT PANEL CONTROL & METER board, adjust S1 dip-switches with switch 1, 3, and 4 “OFF” and
switch 2 “ON”.
39. Set the front panel FREQUENCY SELECT pushwheel switches as follows:
DECIMAL 7 (far left digit) = “1
DECIMAL 6 = “1”
DECIMAL 5 = “0”
DECIMAL 4 = “0”
DECIMAL 3 = “0”
DECIMAL 2 = “0”
DECIMAL 1 (far right digit) = “0”
40. Depress and release the front panel EXECUTE pushbutton switch. The SRPT-40A is now out of Reverse Power
Calibration mode.
45. Set the front panel FREQUENCY SELECT pushwheel switches as follows:
DECIMAL 7 (far left digit) = “1
DECIMAL 6 = “2”
DECIMAL 5 = “0”
DECIMAL 4 = “0”
DECIMAL 3 = “1”
DECIMAL 2 = “0”
DECIMAL 1 (far right digit) = “0”
46. Depress and release the front panel EXECUTE pushbutton switch. This command will enable VSWR Foldback.
47. Set the front panel FREQUENCY SELECT pushwheel switches as follows:
DECIMAL 7 (far left digit) = “1
DECIMAL 6 = “4”
DECIMAL 5 = “0”
DECIMAL 4 = “0”
DECIMAL 3 = “1”
DECIMAL 2 = “0”
DECIMAL 1 (far right digit) = “0”
48. Depress and release the front panel EXECUTE pushbutton switch. This command will enable the front panel
POWER ADJUST pot.
49. Re-connect the 50-Ohm load on the WATT METER.
50. Rotate the WATT METER element clockwise 180 degrees.
51. Put the TRANSMIT/STANDBY switch in the “TRANSMIT” position.
52. Tweak the front panel POWER ADJUST pot fully clockwise.
53. Adjust the MAX PWR pot (R74) on the SYNHESIZER to the desired maximum output power.
54. Replace the cover on the SYNTHESIZER.
55. On the FRONT PANEL CONTROL & METER board, adjust S1 dip-switches with switch 1 and 2 “ON”, and 3 and
4 “OFF”. This places the SRPT-40A back into normal operation.
