6. Enter the tuning frequency into the Communication Analyzer (the value displayed on the
Tuner GUI under the heading of “Frequency Points”).
7. Click the “PTT Toggle” button within the Tuner environment to key up the radio.
8. Adjust the softpot value until 60% of the rated system deviation (RSD) is achieved.
9. Click the “PTT Toggle” button within the Tuner environment to de-key the radio.
10. Click “Write” to save the new tuned softpot value into the radio’s codeplug.
Note
If enabled, the Wireline’s Automatic Level Control (ALC) and Wireline Squelch Hysteresis
features are automatically turned off when the radio is keyed up from the “PTT Toggle”
button within the Tuner environment. The features are automatically re-enabled when the
radio is de-keyed by pressing the “PTT Toggle” button or when leaving the Tuner
environment.
Note
The Tuner aligns this parameter in a 12.5 kHz channel spacing, so 60% is 1.5 kHz of
deviation. If the CPS is set for 25 kHz operation, the base station/repeater will automatically
scale the deviation by a factor of two when it is outside the Tuner environment.
