Message Level Potentiometers
Five of the 12 pots located on the 7K Main Board are used to set levels
associated with messages. The five pots are shown in the table which follows:
Message Level Potentiometers
Controller Main Board
Pot Sets Level
R100 DTMF to transmitter
R101 CW to phone line
R102 CW to transmitter
R103 tone page to transmitter
R108 Speech Synthesizer Module
•
All pots are adjusted clockwise to increase level, and counter-clockwise to
decrease level.
•
R100 adjusts the level of the DTMF characters sent to the transmitter. The
level of DTMF characters sent to the phone line during autopatch dialing is
not adjustable.
•
R101 adjusts the level of CW characters and beep characters sent into the
phone line.
•
R102 adjusts the level of CW characters and beep characters sent to the
transmitter. Many repeater owners adjust the level of CW to a low deviation.
(.5–1.5KHz) to prevent interference with voice conversations.
•
R103 adjusts the level of tone pages (single-tone, two-tone sequential, and
5/6-tone) sent to the transmitter. Typically, the deviation for these types of
pages is 3 to 3.3KHz. Pages sent to the phone line as acknowledgments
will be at the same level as CW characters sent to the phone line.
•
R108 adjusts the level of the speech synthesizer, and controls the level of
speech characters to both the transmitter and the phone line.
