Customizing Testing
Specifying Channel Information
For each channel that you wish to specify, you must enter the following
information into the
Channel Information screen:
• RX Freq (MHz)
• Enter the receive frequency of your radio in (MHz).
• TX Freq (MHz)
• Enter the transmit frequency of your radio in (MHz).
NOTE: Enter a −1 in the RX or TX test frequency fields to have all subsequent frequencies ignored
when testing is started.
• Sq Freq/Code (for RX Freq)
• If you are testing receiver CTCSS or CDCSS (test parameter 8 is set=1), you must
enter the receive squelch frequency or code. Otherwise, leave this field empty.
1. Enter a CTCSS frequency, for example, 91.5 Hz as “CT FR91.5”, or
2. Enter a CTCSS tone code, for example, “ZZ” for 91.5 Hz as “CT ZZ”. The tone
codes supported by the software are shown in table 17, "CTCSS Tone Codes"
on page 248, or
3. Enter a CDCSS code word, for example “CD 023” (octal). The code words
supported by the software are shown in table 18, "CDCSS Code Words" on
page 249.
• Sq Freq/Code (for TX Freq)
• If you are testing transmitter CTCSS or CDCSS (test parameter 23 is set=1), you
must enter the transmit squelch frequency or code. Otherwise, leave this field
empty.
1. Enter a CTCSS frequency, for example, 91.5 Hz as “CT FR91.5”, or
1. Enter a CTCSS tone code, for example, “ZZ” for 91.5 Hz as “CT ZZ”. The tone
codes supported by the software are shown in table 17, "CTCSS Tone Codes"
on page 248, or
2. Enter a CDCSS code word, for example “CD 023” (octal). The code words
supported by the software are shown in table 18, "CDCSS Code Words" on
