ELECTRONIC VOICE DELAY
Option 9801
In VOX mode, word clipping or word loss is directly proportional to
radio T/R speed in simplex systems and repeater pick up time when used
through repeaters. The slower the system, the more desirable voice
delay becomes.
The 9801 electronically delays audio originating from the telephone by
.5 second. This in effect means that the transmitter has been keyed
for .5 second before the audio even began! This timing makes word loss
virtually impossible.
The 9801 is essential when using the 9800 through repeaters from a
Control Station. It is also recommended for use in straight VOX
simplex mode operation especially when connected to a slow switching
base station radio.
INSTALLATION
The 9801 can be field installed in about two minutes:
1. Cut JP-1. (Adjacent to the voice delay connector)
2. Remove two 6-40 5/16 inch machine screws on either side of
the voice delay connector. Remove one additional machine
screw adjacent to resistor R70.
3. Place a No. 6 3/16 inch spacer over each mounting hole.
4. Drop the 9801 over the connector and down onto the spacers,
component side up.
5. Install three 6-40 1/2 inch machine screws and lockwashers to
secure the 9801.
