If the line on the RIT control doesn't point to the dot at the 12 o'clock position, it can be adjusted as follows, if desired. WIth the radio right-side up, locate the three tuning coils in the front left corner of the main circuit board. The coil on the right is labeled L117 and adjust CW, It will not be adjusted. With the RIT control pointing at 12 o'clock and while listening to a signal known to be on center frequency, turn MODE switch to LSB and adjust it's corresponding tuning coil until the signal is perfectly tuned. There will be some interaction between the tuning coils, so it may be necessary to repeat the above steps a few times until both sidebands are properly centered at 12 O'clock.
Re-solder the speaker leads to the speaker and install both covers.
This completes the modification. The digital display will not change, but the transmit frequency will now move relative to the position of the RIT control.
