(7) Repeat technique of (3) above. Power meter will indicate between 1.13 and 3.13
microwatts. If not, perform b(1) through (4) below.
(8) Connect power meter THERMISTOR MOUNT connector to OUTPUT GS, using
thermistor mount, adapter, and power meter cable.
(9) Turn NAV-GS switch to GS and MICROVOLTS control to 200K.
(10) Repeat technique of (3) above over the frequency range of 329.3 to 335.0 MHz.
Power meter will indicate between 392 and 1350 microwatts. If not, perform b(5) below.
b. Adjustments
(1) Loosen MICROVOLTS control set screws and remove control knob.
(2) Repeat a(3) above while adjusting MICROVOLTS control shaft to physical
position yielding optimum within-tolerance power meter indications.
(3) Replace control knob on shaft and align corresponding control mark with index
mark on front panel.
(4) Repeat a(4) and (5) above. If beyond tolerance indications are obtained,
reposition MICROVOLTS control knob shaft setting so that all indications for a(2) through
(7) above are within tolerance.
(5) Repeat a(9) and (10) above while adjusting R1544 (fig. 2) for optimum within
tolerance indication.
10. RF Output
a. Performance Check
(1) Connect frequency counter (A3) to TI OUTPUT NAV, using cable (B8) and
adapter (B4).
(2) Position TI controls as indicated in (a) through (g) below:
(a) MICROVOLTS control fully clockwise.
(b) NAV-GS switch to NAV.
(c) MEGACYCLES coarse control to 108.
(d) MEGACYCLES fine control to .0.
(e) LOC-GS control to midrange.
