AFSK Level Adjustment
AFSK level jumper
If you find the “correct” AFSK level setting occurs in the first 20% of the potentiometers range, the adjustment may
be difficult. If you find this adjustment difficult, the internal AFSK adjustment level jumper may be moved to the
LOW setting which will improve the adjustment range of the potentiometer.
To locate the internal AFSK level jumpers in the DSP-232, remove the six screws that secure the top chassis, and
carefully remove it.
Look for jumpers JP10 and JP11 near the fuse at the rear of the DSP-232 as shown in figure AD-1 below. Jumper
JP10 controls the output level of radio port 1, and JP11 controls the output level of port 2. When the jumper is
towards the right, the output level is high (high and low are printed on the circuit board near the jumper for your
convenience). Move the jumper for the radio port being adjusted to the left two pins to set the AFSK output level to
LOWer range. Repeat step 7 of FM Transceiver Ajustments on page 3-6 of this manual when this has been
completed.
