1000 pf is the same as .001 uf. This notation (102) is similar to the
resistor color code to indicate resistance values.
A14. Install C3, .001 uf.
A15. Install C4, .001 uf.
A16. Install C1, .001 uf (Don't confuse with C65).
A17. Install C65, .1 uf. It may be marked .1 or 104. (As above, 104 means
a one, a zero and four zeros = 100,000 pf which is the same as .1 uf) (On
the schematic, C65 is located near J4 and U4 and couples packet audio
to the microphone input line.)
A18. Select D9, one of the many 1N914 or 1N4148 switching diodes used
in the circuit. Don't confuse these diodes with the smaller PIN and
varactor diodes used in later stages. Notice the dark band at one end
designating the cathode and notice how the cathode end is imprinted
right on the PC board.
A19. Install D9.
A20. Install R42, 2.2K (red-red-red). This is an "upright" installation like
D18, previously installed.
Almost all resistors will be installed this way. Like C65, R42 and D9 are
shown near J4 on the schematic and complete the External PTT connection
between U4 and J1.
No testing of the Packet components is required, but make sure all parts
values are correct and that D9 is oriented correctly.
