AM radio alignment using all Heathkit vintage equipment

[JRUBIN]

The radio under test is a Hallicrafters S38C aligned with the equipment restored as mentioned in my other threads

All Heathkit models:
IG102 RF signal Generator
IG-72 Audio Generator
IM-11 VTVM
O-12 Oscilloscope

Several techniques employed, get some popcorn, this is a long one...

Enjoy,
