INTRODUCTION
All FM transmitters require a device that will supply an RF
driving voltage of sufficient amplitude to drive the succed-
ing amplifier stage to the required output power level.
In
addition,
this device must have necessary provisiohs made for
frequency modulating the carrier the proper amount.
These requirements are fulfilled by the M6095 exciter unit.
The exciter panel is standard 19" wide for rack mounting,
height is 14".
A rear dust cover is provided that extends
2-1/2" beyond the back of the panel.
This dust cover is held
on by four acorn nuts easily removed from the front of the
panel.
The highest unit on the front of the panel is the
crystal oven which extends 4-1/2" beyond the panel proper.
The unit is complete with its own power supply.
It is light
in weight,
21-1/2 lbs,
this makes it very easy to remove the
unit from the cabinet or rack in which it is mounted and to
place it on a bench.
All that is needed to operate the unit
is an AC cord connected from TB101-78c8 to a 117 V. AC outlet.

INSTuLLATION
Generally, when the exciter unit is received at the point
of operation it will be mounted in a cabinet along with
additional amplifier stages.
The unit finds its greatest
usage in driving 50 watt and 250 watt amplifier stages.
With
some additional external metering,
the unit becomes a complete
10 watt FM transmitter.
Forced air cooling is not required for the unit.
Sufficient
ventilation should be allowed to provide normal circulation
and up- draft at least for the front of the panel, where all
of the tubes are mounted.
External wiring to the unit consists of the following:
1.
A shielded,
twisted pair that connects to TB101-1
-2-3.
The shield should connect to TB101-3 which is ground.
These are the audio input terminals.
Audio requirements for
100% modulation are approximately /10 DBM,
and the input im-
pedance is 600 ohms.
2.
Two wires connected to TB101-78S.
These wires are
to provide operating voltae'es for the unit.
