8.7.1
Tuning the Modulation Limit (with no Tx Data and no PL)
Prerequisites: Obtain the following:
• Wattmeter (Communication Analyzer)
• Service monitor or counter
• 20 dB pad
• Standard Type A to Type B USB cable
• Personal computer
Procedure:
1 Connect the repeater antenna port to the attenuation pad, if necessary, before connecting to the
Communication Analyzer.
2 Power the repeater from a DC source.
3 Apply a 1 kHz signal at 1.2 Vrms to Pin 1 of the Aux connector.
Signal ground is Pin 4 of the Aux connector.
4 Launch the Tuner application.
5 To read the softpot values, click Read.
6 In the tree view, select TX, then select Modulation Limit.
7 Enter the tuning frequency into the Communication Analyzer (the value displayed on the Tuner
application).
8 To key up the repeater, click PTT Toggle.
9 Adjust the softpot value until the maximum deviation is 92% of the rated system deviation
(RSD).
This adjustment is tested in a 12.5 kHz channel spacing, so 92% of 2.5 kHz is 2.3 kHz.
10 Set the modulation limit to 92% so that any additional deviation incurred by the transmitter VCOs
over temperature is compensated for.
Channel Spacing
(kHz)
RSD (kHz) 92% of RSD (kHz) Tolerance (Hz)
12.5 2.5 2.3 +0/ -50
11 To de-key the repeater, click PTT Toggle.
12 To save the new tuned softpot value into the repeater codeplug, click Write.
