Alignment

- [3] REF Deviation

This parameter is used to align the REF Deviation.

¦Press [Enter] on “[3] REF Deviation” to align REF Deviation.

¦Select the Channel “1“ in alignment range.

¦Adjust the AF generator output level to 388mVrms(–6dBm) at 100Hz to the pin 3 of the J1502.

¦Press the [Space] key on the keyboard to acti- vate the transmitter.

¦Press the [UP] or [DWN] key, as needed, to set the modulation wave as follows.

¦Press [Enter] to lock in the new data.

¦Select the Channel “2,“ and set the modulation wave, same as Channel “1.“

- [4] CTCSS Deviation

This parameter is used to align the CTCSS deviation.

¦Press [Enter] on “[4] CTCSS Deviation” to align CTCSS Deviation.

¦Select the Channel “1“ in alignment range.

¦Press the [Space] on the keyboard to activate the transmitter, and injects a CTCSS test tone.

¦Press the [UP]/[DWN] key, as need, to set the CTCSS Deviation (Wide) to the following speci- fication.

¦Press [Enter] to lock in the new data.

¦Select the Channel “2,“ and set the CTCSS De- viation (Narrow), same as Channel “1.“

CTCSS Deviation (Wide): 0.70 kHz (±0.1 kHz)

CTCSS Deviation (Narrow): 0.35 kHz (±0.1 kHz)

- [5] DCS Deviation

This parameter is used to align the DCS deviation.

¦Press [Enter] on “[5] DCS Deviation” to align DCS Deviation.

¦Select the Channel “1“ in alignment range.

¦Press the [Space] key on the keyboard to acti- vate the transmitter, and injects a DCS test tone.

¦Press the [UP] or [DWN] key, as needed, to set the DCS deviation (Wide) to the following speci- fication.

¦Press [Enter] to lock in the new data.

¦Select the Channel “2,“ and set the DCS devia- tion (Narrow), same as Channel “1.“

DCS Deviation (Wide): 0.60 kHz (±0.1 kHz)

DCS Deviation (Narrow): 0.30 kHz (±0.1kHz)

¦The actual DCS deviation will increase around 20% based on the above alignment as follows,

Actual DCS Deviation (Wide): 0.70 kHz

Actual DCS Deviation (Narrow): 0.35 kHz

[1] Common RX

- [0] Tight NSQL

This parameter is used to align the noise level in squelch

Tight. It adjusts this alignment RX Tuning after ending.

¦Select the Channel “1“ (MID frequency channel) in alignment range.

¦Set the SG output level to –2.5 dBµV, and obey the message.

- [1] Threshold NSQL

This parameter is used to align the noise level in squelch

Threshold. It adjusts this alignment RX Tuning after end-

ing.

¦Select the Channel “1“ (MID frequency channel) in alignment range.

¦Set the SG output level to –8.5 dBµV, and obey the message.

- [2] RX Tune

This parameter is used to align RX Tune.

¦Select the Channel “1“ (MID frequency channel) in alignment range.

¦Set the SG output level to –8.0 dBµV.

¦Pressing the [UP] or [DWN] key, Adjust the RX Tune Level for best SINAD.
