AT-3 TRANSMITTER
The following is the recommended procedure
Transmitter into operation:
AC OPERATION
1. Transmitter function switch 1.
off; power supply switch off.
2. Connect antenna and ground.
5. Plug power supply into
transmitter.
4. Turn power supply switch
to known line voltage or
until meter reads into green.
5. Insert crystal for desired
frequency and pull out hand
key.
for placing the AT-3
BATTERY OPERATION
Transmitter switch in off
position.
2. Connect antenna and ground.
3. Plug battery into transmitter.
4. Turn function switch to R.
position.
5. Battery may be checked by
moving meter range selector
switch to the battery position.
Meter indicator should deflect
into the green region on the "B"
scale.
6. Adjust the #1 and #2 thumb wheels until the coil wiper wheels,
which are seen through the windows, read approximately the desired
frequency. The position of #2 wiper must be estimated as it will
vary with loading for a given frequency.
7. Place "tune to max" meter range switch to the "A" position.
8. Place loading switch in the #11 position.
9. Depress key and tune #1 thumb wheel until a maximum reading is
observed on meter #1. This reading should be in the upper part
of the green region of scale "A"; a deflection into the red area
indicates a defective transmitter.
10. With the key still depressed, tune thumb wheel #2 for a dip on
meter #1. When a dip is obtained, turn the loading switch to the
0 next lowest position and retune for another dip. This process is
repeated until the din becomes very shallow then the tuning may be
finished by observing the "tune to max" meter and obtaining a
maximum reading. If the meter runs off scale in the "A" position,
it can be brought back on scale by moving the range switch to the
"B" position. The transmitter is now ready to operate.
