The injected IF frequency has to be modulated by an AF tone, can be 440hz or 1khz usually. The level of modulation should be 30%, just enough to identify the RF as a unique tone.

That "box" on the far left of the control panel, push "on" push choices of "AM" choose 1K or 400hz, press levels of arrow up or down look on screen for confirmation. Fancy generator, all my stuff is 50's & 60's tubes...

Once you get it going keep RF output very low so AVC does not actuate, then do the alignment...
