Message Level Potentiometers - S-COM 7K Manual

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:

R100
R101
R102
R103
R108
• 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.
