[Drake] Missing R7 Alignment Instruction Resolved?

[LeeCraner at aol.com]

If you've ever tried to align your R7, you've undoubtedly noticed that there 
is a missing step in section 3-10 of the alignment instruction.  Specifically, 
3-10 b) instructs you to "Adjust AGC bias pot (R1127) fully clockwise" but 
then it never tells you how to reset the pot.  In other words, if you follow the 
instructions, R1127 is left fully clockwise.

After some experimentation, I think I've resolved the error.  I'd like your 
input to my corrections to section 3-10, reproducted below.  Corrections are in 
italics.  If you copy of this does not show the italics, the corrections I've 
added are steps i. and ii, to step b., the parenthetical text in steps c., d. 
and e. and all of step h.

a) Connect an audio voltmeter across R7 speaker terminals.

b) Adjust AGC bias pot (R1127) fully clockwise.
       i) Adjust IF gain pot (R1138) fully counterclockwise.
       ii) With no signal applied to the R7 antenna terminal, adjust AGC bias 
pot (R1227) counterclockwise until background noise audio output just begins 
to fall as indicated on the audio voltmeter.

c) Apply a 0.5 uV signal at 14.3 mHz to the Main/Alt antenna input.  Place 
radio in the 2.3 kHz, SSB/CW mode.  Tune PTO for maximum audio output.  Peak 
L701 (cover removed).  Turn IF gain pot (R1138) clockwise until audio output no 
longer increases with additional increase in pot setting.  Then turn pot 
counterclockwise until audio output decreases 3 dB.  (Note:  my guess is that the 
preceding sentence was to have read, "Then turn AGC bias pot counterclockwise 
until audio output decreases 3 dB."  However, the same thing is accomplished 
with steps i) and ii) added above).

d) Increase signal generator input to 1 uV and adjust S-meter zero pot 
(R1119) for a reading of S1-1/2 on S-meter (alternatively, adjust R1119 so that the 
S-meter just begins to move off of the S1 minimum reading mark with no output 
from the signal generator.  Then increase signal generator output until the 
S-meter just begins to move again.  Adjust R1119 so that the S-meter reads just 
slightly above S1).

e) Increase signal generator input to 50,000 uV and adjust 60 dB over S9 
meter set pot (R1106) for 60 dB over S9 on meter (alternatively, adjust R1106 for 
an S9 reading with a 50 uV signal.  However, this may not result in a 60 dB 
over S9 reading with a 50,000 uV signal applied).

f) Repeat steps d & e until no further change is noted.

g) Install rear card cage cover.  Repeak L701 with signal generator level of 
approximately 1 uV.

h) If audio appears distorted after making the above adjustments, adjust IF 
gain pot (R1138) (accessible with the rear card cage cover in place) clockwise 
until distortion disappears. (Note:  the final adjustment of R1138 may have to 
be done after using the receiver for a few days).
