Key the transceiver on FM mode without microphone input. Key the transceiver and adjust T1012 and T1013 alternately for the maximum indication on the RF millivoltmeter.Ĭ. Key the transceiver and adjust T1020, T1012, and T1005 alternately for the maximum indication on the RF millivoltmeter.Ī. Connect a RF millivoltmeter to J1002 terminated by 50ohmī. Confirm that the indicated voltage is at least 70mVrms or 200mVp-p.Ī. Key the transceiver on CW mode and adjust T1021 for the maximum indication on the RF millivoltmeter.Ĭ. Connect a RF millivoltmeter or an oscilloscope to Q1055 5pin (T1087).ī. Confirm the indicated voltage is at least 120mVrms or 330mVp-p.Ī. Adjust T1024 and T1026 alternately for the maximum indication on the millivoltmeter or for the maximum amplitude on the oscilloscope.Ĭ.
Connect a RF millivoltmeter or an oscilloscope to Q1038 5pin (TP1067).ī. Connect the “13US” line between PA unit and Final Unit again as it should be.Ī. Press the PTT and adjust VR5402 for an indication of 76mA +/- 4mA on the ammeter.Į. Press the PTT and adjust VR5401 for an indication of 38mA +/- 2mA on the ammeter.ĭ. Turn both VR5401 and VR5402 fully to counterclockwise.Ĭ. If the “13US” line has already been connected by a wire, remove it and connect an ammeter.ī. Connect an ammeter at each “13US” pin on PA Unit and Final Unit. Disconnect the ammeter and reinstall the jumper connector at J3006.Ī. Press the PTT and adjust VR3002 for an indication of 18mA +/- 2mA on the ammeter.į. Remove the jumper connector J3006 and insert an ammeter.Į. Disconnect the ammeter and reinstall the jumper connector at J3005ĭ. Press the PTT and adjust VR3001 for an indication of 28mA +/- 2mA on the ammeter.Ĭ. Remove the jumper connector J3005 and insert an ammeter.ī. Nothing should be connected to the CW Key Jack.Ī. When the reference input is activated, the voltmeter shows at least 3.5V and LCD displays as it normally should do.īefore alignment, set the mode on CW and tune the transceiver to 1.800MHz.
When the reference input is not activated, the voltmeter shows less than 0.5V and “UNLOCK” is displayed on the LCD.Ĭ. Connect a DC voltmeter to J2002 1pin (TP1001).ī. Confirm that the RF level is at least +5dBm or 400mVrms.Ī. Connect a RF millivoltmeter to J2002 11pin and tune the transceiver to 28.000MHz.ī. Then confirm that the correct voltage is present, or adjust the listed components for the required voltage.Ī.
Connect a DC voltmeter to J2002 6pin (TP1007) and referring to the table below, tune the transceiver to each frequency listed. Connect a RF millivoltmeter or an oscilloscope to the J5002 2pin (TP1047) and confirm that the output level is at least 70mVrms or 200mVp-p.Ī. Adjust the trimmer capacitor (TC5001) for 22.625000MHz +/- 5Hz on the frequency counter.Ĭ. Connect a frequency counter to J5002 2pin (TP1047).ī. You can always opt-out if you don't like it.A.
