Tuner Adjustment Method
FM Section
* Necessary measurement equipment
RDS/STEREO Multiplexer, FM/AM Signal Generator, Audio Analyzer, Oscilloscope, Digital Volt Meter (DVM)
(A) Center adjust
RDS/STEREO Multiplexer Setting
- MODE : MONO - Audio Frequency : 1KHz
FM Signal Generator Setting
- Deviation : 75KHz - Radio Frequency : 98.1MHz - Output Level : 66dB
RX-1050 Setting
- FM Frequency : 97.9MHz - FM MODE : MONO
1. Turn FM Signal Generator Modulation on
2. Connect DVM (+)(-) terminals to Jumper J7 and J8 and measure the volt.
3. If measured voltage is not adjusted within ±10mV, Make this measured volt '0' by adjusting T04 (FM-DET-A Coil).
: The adjustment should be within ± 10mV
4. After this adjustment, measure THD(Total Harmonic Distortion) with Audio Signal Generator
5. Adjust THD to minimum point with T05(FM-DET-B Coil). : THD shuold be within 0.5%
(B) Channel Separation adjust
RDS/STEREO Multiplexer Setting
- MODE : STEREO ( ONLY L-CH Signal OUT ) - Audio Frequency : 1KHz
FM Signal Generator Setting
- Deviation : 75KHz - Radio Frequency : 98.1MHz - Output Level : 66dB
RX-1050 Setting
- FM Frequency : 98.1MHz - FM MODE : STEREO
1. Turn FM Signal Generator Modulation on after modulating only L-CH (or only R-CH) at STEREO Multiplexer.
2. Confirm if 'STEREO'indicator is turned 'ON' on the display
3. Measure output level via Audio Signal Analyzer and make the level as standard.
4. Turn FM Signal Generator Modulation on after modulating only R-CH (or only L-CH) at STEREO Multiplexer.
5. Measure output level via Audio Signal Analyzer (measure per a dB)
6. If meaured output level is not lower than -40dB, Adjust output level to minimum position with VR03 ( CH-SEPA. ADJ.).
: lower than -40dB
(C) TUNED Level adjust
RDS/STEREO Multiplexer Setting
- MODE : STEREO - Audio Frequency : 1KHz
FM Signal Generator Setting
- Deviation : 75KHz - Radio Frequency : 98.1MHz - Output Level : 26dB
RX-1050 Setting
- FM Frequency : 98.1MHz - FM MODE : STEREO
1. Turn FM Signal Generator Modulation 'ON' (confirm if output level is 26dB)
2. Change the output level of the Generator from 20dB to 30dB
and Confirm if 'STEREO' & 'TUNED' indicator of the DISPLAY turns on at 26db(±5 dB)
3. If these indicators do not turn on at higher than 26dB(±5dB) or do not turn off at lower than 26(±5dB) ,
Adjust VR02 ( FM-ADJ ) up to the moment where 'STEREO' & 'TUNED' indicator turns OFF & ON at 26dB.
4. Confirm if 'STEREO' & 'TUNED' turns OFF when decreasing the output level slowly from 26dB to 25dB, 24dB ~~~.
(Repeat the above 3. if not OFF in lower than 24dB.)
5. Push RX-1050's TUNE UP or DOWN button "long" at Signal Generator Output Level 26dB and start Auto search.
Confirm if search stops at FM Frequency 98.1MHz.
(Examine both of High Freq. -> 98.1MHz search , Low Freq. -> 98.1MHz search)
9

AM Section
* Necessary measurement equipment :
AM Signal Generator, Audio Signal Analyzer, Dummy Load, Oscilloscope, Digital Volt Meter (DVM)
(A) VT adjust
AM Signal Generator Setting
1. Adjust AM Frequency of RX-1050 to 522KHz. (or 520KHz)
2. Connect (-) terminal of DVM with GND ( or chassis ) and connect (+) terminal
with Jumper J3 ( VT CHECK ) and mesaure voltage. ( Low Freq. VT)
3. Adjust VT to 1.1V with T02 (AM-OSC Coil).
* In case of USA version, AM freq. range is 520KHz ~ 1710KHz. So, adjust as below.
at 520KHz, VT = 1.1V ( Low Freq. VT)
(B) Output Level adjust
AM Signal Generator Setting
- Modulation : 30% - Audio Frequency : 400Hz - Output Level : 100dB
- Radio Frequency : 603KHz (or 600KHz )
RX-1050 Setting
- AM Frequency : 603KHz/1404KHz/999KHz (or 600KHz/1400KHz/1000KHz)
1. Turn AM Signal Generator Modulation ON
2. Adjust RX-1050 AM Freq. to 603KHz (or 600KHz) and measure output level with Audio Signal analyzer.
3. Adjust output level to maximum point with T01 ( AM-ANT ).
4. Adjust AM Signal Generator & RX-1050 AM Frequency to 1404KHz (or 1400KHz) and measure output level.
5. Adjust output level to maximum point with TC01 (White Trimmer).
6. Repeat above 2.~ 5. steps 2 ~ 3 times until adusting to best output level.
7. Adjust AM Signal Generator & RX-1050 AM Frequency to 999KHz (or 1000KHz) and measure output level.
8. Adjust level to maximum position with T03 (AM-IFT).
(C) TUNED Level adjust
AM Signal Generator Setting
- Modulation : 30% - Audio Frequency : 400Hz - Radio Frequency : 999KHz (or 1000KHZ)
- Output Level : 84dB
RX-1050 Setting
- AM Frequency : 999KHz (or 1000KHz)
1. Turn AM Signal Generator Modulation ON ( Make sure if Output level is 84dB )
2. If 'TUNED' indicator does not turn on at higher than 80~86dB(Generator output),
Adjust VR01 ( AM-ADJ ) up to the moment where 'TUNED' indicator tunrs OFF & ON again
3. Confirm if 'TUNED' turns OFF when decreasing the output level of AM Signal Generator slowly from 84dB to 80dB.
4. Push RX-1050 TUNE UP or DOWN button "long" at AM Signal Generator Output Level 84dB and start AUTO search.
Confirm if search stops at AM Frequency 999KHz (or 1000KHz).
< Check with both of High Freq. -> 999KHz(or 1000KHz) search , Low Freq. -> 999KHz(or 1000KHz) search >
