Scott, you did not yet say, is it a SX-62 A, or B or no-suffix?

It seems that you did the 455 IF ok ????but the 10.7 IF ?is the problem? ??or are you all the way down to the FM ?detector ??? I was just looking ?quickly at the 62-A instructions. ?

I did not see any indication of the sig gen output power/voltage so I wonder about that!

?you are saying that there is so much gain in the 7F8 mixer section ?that it somehow ?swamps out the Local oscillator ? ?but only at 10.7,not 455?

IS this where you are?

IF ALIGNMENT (10.7 MC) - Set the controls as follows:

BAND SELECTOR. . . . . .. 27/56 mc range

RECEIVE/STANDBY switch .. RECEIVE

CALIB. XTAL switch ...... OFF

NOISE LIMITER switch ..... OFF

VOLUME .............. Near Maximum

RECEPTION control. . AM

SELEC TIVITY control. NORMAL/SHARP

SENSITIVITY control . Near Maximum

Set tuning dial pointer at approx. midscale.

?

Connect the high side of the signal generator through an 0.1 mfd. capacitor to pin #1 of the 7F8 converter tube. Set

signal generator at 10.7 mc and adjust slugs S-4,6.9,13 and 15 for maximum output. Now set slugs S-2 and S-l1 for

maximum output but do not readjust slugs S-4 6.9, 13 and 15.

翱谤……………….

Set RECEPTION control at FM and adjust slug S-16 for maximum output. Now set Slug S-7 for the null or minimum

output as indicated on the output meter. Check the discriminator by slowly tuning the signal generator through 10 .7 mc

and observe the two maximum audio level readings on the output meter. If the two peaks are equal the job is done ; if

not it may be necessary to reset Slug S-16 until a reasonable balance is obtained.

I don’t see how the RF gain[sensitivity] affects the 6F8, but that is a big schematic to try to digest.

Somebody must know
