I rechecked the manual and Mike is correct. Pin 9 is the parallel
connection to the internal speaker.

Stan, Wayne,

We had a couple of the ALPHA 100's in the Alice Springs Gliding Club.
Being their "radio fix-it man" for a few years I have the schematic
for the radio.

Wayne's pinout information is correct except for pin 6. This is the
PA Speaker output on the ALPHA 10 (Sound only when the mike is keyed).
On the ALPHA 100, pin 3 and pin 9 are jumpered internally and
represent the external speaker "hot" connection.

The following information is found in the Genave Alpha/10 installation
manual:

Pin 1 is the +14 volt connection and pin 12 is the ground. The
speaker's
"hot" connection is pin 6. Pin 4 is the mike key and pin 5 is mike
audio.
The headphone connection is pin 11.

The speaker should be 3-4 ohms.

I have a Genave Alpha/100 transceiver. The built in speaker has gone
bad so I want to hook up an external speaker. Does anyone have a
manual, wiring diagram or experience wiring an external speaker to
this unit. Any help would be appreciated.
