1-24 (No.RA011)4.2 Frequency and SignalingThe transceiver has been adjusted for the frequencies shown inthe following table. When required, re-adjust them following theadjustment procedure to obtain the frequencies you want in ac-tual operation.Test frequencyAnalog SignalingDigital SignalingRAN: Radio Access NumberPN9: Pseudo-Random Pattern (for production only)*1: To output 150Hz square wave (for production only)4.3 Preparations for Tuning the TransceiverBefore attempting to tune the transceiver, connect the unit to asuitable power supply.Whenever the transmitter is tuned, the unit must be connected toa suitable dummy load (i.e. power meter).The speaker output connector must be terminated with a 4Ωdummy load and connected to an AC voltmeter and an audio dis-tortion meter or a SINAD measurement meter at all times duringtuning.5 reference level adjustments frequencyChannel No. RX (MHz) TX (MHz)1 485.05000 485.100002 450.05000 450.100003 519.85000 519.900004 485.00000 485.000005 485.20000 485.200006 485.40000 485.400007~16 - -Signaling No. RX (Decode) TX (Encode)1 None None2 None 20Hz Square wave3 QT 67.0Hz QT 67.0Hz4 QT 151.4Hz QT 151.4Hz5 QT 210.7Hz QT 210.7Hz6 QT 254.1Hz QT 254.1Hz7 DQT D023N DQT D023N8 DQT D754I DQT D754I9 DTMF Decode(Code: 159D)DTMF Encode(Code: 159D)10 None DTMF (Code: 9)11 None MSK (1010)12 FleetSync(100-1000)FleetSync (100-1000)13 None Single Tone (1000Hz)14 2-tone DecodeA: 304.7HzB: 3106.0Hz2-tone EncodeA: 304.7HzB: 3106.0Hz15 None DTMF Tone (1477Hz)16 Single Tone(979.9Hz)Single Tone (979.9Hz)17 None MSK PN918 None DTMF (Code: 3)SignalingNo.RX (Decode) TX (Encode)1 RAN 1 RAN 12 None PN93 RAN 1 Maximum Deviation pattern4 FSW +PN9 MOD Set-up *15 Tone Pattern (1031Hz) Tone Pattern (1031Hz)TEST CH RX (MHz) TX (MHz)Low 450.05000 450.10000Low’ 467.55000 467.60000Center 485.05000 485.10000High’ 502.55000 502.60000High 519.95000 519.90000
