The manual for the Kenwood SM-220 and TS-940 alignment procedure provides specific instructions for adjusting the pan display, including ensuring the correct amplitude of the center trace and equal roll-off at the edges, while noting that the TS-940S uses a 100 kHz marker instead of a 25 kHz marker. It also guides users to adjust VR202 and TC201 for optimal display results, emphasizing that the center trace should ideally be the highest, with the remaining steps following the original SM-220 manual.
Manual Overview
The alignment procedure for the Kenwood SM-220 with the TS-940 transceiver requires specific adjustments to ensure proper display and functionality. During the PAN display adjustment, it is important to note that the scope marker injected into the transceiver’s IF will not be audible through the TS-940S speaker or headphones. The TS-940S uses a 100 kHz marker, resulting in three visible traces on the display. The procedure involves adjusting for maximum amplitude of the center trace and ensuring equal roll-off at the edges, with the center trace ideally being the highest. In step 8, adjustments to VR202 and TC201 are necessary to achieve the desired display configuration. The manual emphasizes that while adjustments are required, they will not significantly alter the display. The remaining steps should be followed as outlined in the SM-220 manual, ensuring that all traces are approximately the same height, with the center trace being the most prominent if possible.
Quick Issues Covered
- Adjust VR202 and TC201 for optimal pan display alignment.
- Center trace should be higher than edge traces on display.
- TS-940S uses 100 kHz marker, not 25 kHz, for calibration.
