3 Alignment Procedure --- GRUNOW MODEL 1101
Chassis 2A & 9B
I. F. ALIGNMENT
A. Connect signal lead of oscillator to grid of GF7 (lst. Detector)
tube in 2A Chassis through .25 mfd. condenser and ground lead of
H - oscillator to 2A Chassis.
' . Place oscillator in operation at 262 K.C.
' C. Turn receiver volume control to maximum.
| D. Attenuate oscillator output to lowest value consistent with
obtaining a readable indication on the output meter.
E. Adjust the five (5) I. F. Trimmers on the 2A and 9B chassis until
maximum output is indicated on the output meter.
F. During alignment, maintain as low a value of signal as will
allow obtaining of accurate adjustment.
DIAL SETTING
a. The last mark on the low frequency end of the dial should be '
' directly over the dial indicator.
b. To set dial correctly, turn dial knob to low frequency end until
I condenser is fully meshed, then loosen three set screws that hold
dial and reset, then tighten screws.
a. Connect signal lead of oscillator through .0002 mfd. condenser
' to antenna binding post and ground lead to ground post of 9B
b. Place oscillator in operation at 1400 K.C.
c. Turn tuning dial to exactly 1400 K.C.
d. Align oscillator trimmer to maximum output.
e. Align antenna trimmer to maximum output.
f. Align lst. Detector trimmer to maximum output.
g. Repeat operation d-e-f in rotation at least three times.
600 K. C. ALIGNMENT
a. Place oscillator in operation at 600 K.C.
b. Tune in signal to maximum (this point does not have to be exactly
at the 600 K.C. dial setting)
c. Adjust the 600 K.C. Trimmer (padding condenser) in the direction
of greatest signal increase and at the same time turn the 2A
dial back and forth through resonance. Continue this procedure
until maximum signal is obtained on the output meter.
A.v.c. ALIGNMENT 4
a. Place oscillator in operation at 600 K.C. as above.
b. Connect shunt across the output meter or disconnect the output
meter from the receiver. Then increase the output of the oscilla
tor to maximum or to the point where the receiver begins to dis-
tort. Reduce the output volume to a low value by means of the re- Q `
ceiver volume control and remove the shunt from the output meter
or reconnect the meter to the receiver.

Alignment Procedure (Continued)
. Turn the A.V.C. trimmer screw in a clockwise direction to the
point of minimum capacity without paying attention to the reading
of the output meter Then gradually turn this screw in a counter-
clockwise direction, watching the action of the output meter
while increasing the capacity of the trimmer A graphical picture
of the results obtained in this adjustment is given in Figure 4
which shows that as the capacity of the trimmer is increased an
output peak will be reached, followed by a dropping off in output
to a minimum value Further increase of the trimmer capacity
causes the output to again rise to a peak after which it drops to
a low value, which is not affected by further increase of the
trimmer capacity. The proper setting of this trimmer is that
which gives the minimum out-put between the two high output peaks.
d. Be very careful in making this adjustment that the trimmer is
adjusted to give operation between the two output peaks, rather
than the minimum output obtained by either a high or low
capacity setting.
e. After the A.V.C. has been adjusted, it may be necessary in some
cases to re-align the I.F. system to obtain maximum gain.
