J. JACK AND SWITCHES:
Now our project will begin to look
complete as we install the jacks and
switches. We only have one component
section to go after we complete this, so
be sure not to lessen the effort you put
into making a nice neat project out of this.
1J. Install S4, an unmodified switch
that we left alone in section B. Make
sure when mounting all of your
switches that they are pressed firmly
to the board so that they will align
properly in the case holes when
completed.
2J. Install S1, the FREQUENCY UP
switch. This is one of the modified
switches.
3J. Install S2, the FREQUENCY
DOWN switch.
4J. Install S3, the MIC IN switch.
5J. Install S5, the AUTO AGC switch.
6J. Install R84, one of the dual 10K ohm potentiometers. Install this part
so that its shaft is perfectly parallel to the PC board before soldering. It is
easy enough to reheat the pads and adjust the pots so they align properly
to the holes if you make a mistake.
7J. Install R62, the other dual 10K ohm potentiometer. Make sure the post
is parallel with the PC board before soldering.
8J. Install R26, the single 10K ohm potentiometer. Solder all three pins as
well as solder the two mounting lugs as well.
9J. Install J4, the microphone jack. Solder all 5 pins.
10J. Install J10, the six pin Molex connector. Make sure and mount the
short ends in the PC board. Also notice that the board layout shows only
the female connector of the 1 watt module, not the male connector that we
are installing.
11J. Install J5, one of the stereo RCA jacks. Make sure and mount these
so the back is square in relation to the PC board and that the jack is
mounted flush to the PC board.
