Ok. Let’s try this again…RCA 9TC240 Alignment

That looks okay. Signal level may be a little low. The important thing is to not be so low you cannot see the peak or too high where it will overload and result in a false reading and adjustment. I would recommend setting the vtvm to the correct range and then adjust the RF generator level until you get an adequate level to adjust on the meter.

FYI the zero discriminator adjustment is part 2 the first is to set the primary t113 (top) to maximum at 21.25MHz.
