The manual provides detailed instructions for setting up and operating various components, including adjusting voltage levels, frequency variations, and phase offsets, as well as ensuring spectral purity and modulation accuracy. It also includes troubleshooting steps such as checking signal levels and adjusting potentiometers to achieve desired performance metrics.
Manual Overview
The manual for Manuals 28 provides detailed instructions for calibration, adjustments, and troubleshooting of specific components. To set the voltage between MP1 and MP2, adjust potentiometer R1 to achieve a range of 8.5 to 8.6 V. Adjust the winding spacing of L5 to set the frequency to 520 ±1 MHz. Ensure the bridge BRI in the tuning voltage line is closed. For level adjustment, measure the level at the HF input ST2 4a,b and adjust the HF level across the 260 to 520 MHz frequency range to remain between -2 dBm and +4 dBm by bending coils L6, L8, L5, and L7. Verify that the tuning voltage exceeds +2.4 V at 260 MHz and 380 MHz. Check the HF signal for oscillation stability and spectral purity, ensuring harmonic distance is greater than 36 dB. Adjust R1/R2 if necessary. For phase control Y4, insert boards Y3, Y5, Y6, Y8, and Y11, and set fixed tuning voltages using potentiometers as per Table 5-19. Adjust the phase offset by setting potentiometer R87 to achieve a distortion factor of 0.4%. For gain switching, open bridge BR1 and check voltages at MP6 according to Table 5-20.
Quick Issues Covered

Installation / Setup
The setup involves several key steps:
1. Adjust the DC voltage between MP1 and MP2 to 8.5…8.6 V using potentiometer R1.
2. Set the frequency to 520 +1 MHz by adjusting the winding distance of L5.
3. Close the bridge BRI in the tuning voltage line.
4. Ensure that all boards except Y3 are inserted: Y4, Y5, Y6, Y7, Y8, Y11.
5. For level adjustment, measure the level at the HF input ST2 4a,b and ensure the HF level across the frequency range 260…520 MHz is between ~2 dBm and +4 dBm.
6. Adjust the HF level by bending the coils L6, L8 or L5, LY.
7. Verify the tuning voltage at 260 MHz and 380 MHz, ensuring it is >+2.4 V.
8. Check the HF signal at the HF input ST2 4a,b for oscillation safety and spectral purity across the 260…520 MHz range. Adjust R1/R2 if necessary.
9. Measure the level at the HF input 20…60 ST4 19a,b, ensuring the signal level is >-14 dBm.
10. For phase control Y4, ensure boards Y3, Y5, Y6, Y8, Y11 are inserted.
11. Set fixed tuning voltages for specific frequencies using potentiometers as per Table 5-19.
12. Adjust the phase offset using R87, ensuring a distortion factor of 0.4%.
13. Connect an analyzer to the HF output and vary the SMFP2 frequency between 320 and 322 MHz, checking the sideband distance.
14. For gain switching, open bridge BR1 and input a 10 kHz, 1 V signal at the test pin connected to R121. Check voltages at MP6 for frequencies as per Table 5-20.
15. For capture aid, remove board Y3, enter frequencies 270 MHz and 340 MHz, and measure the signal at MP5.
16. Set frequencies according to Tables 5-21 and 5-22 and check logic levels at the contacts of connector ST4.
