Agree, for I.F. alignment, follow instructions, for RF (on AM,), I have an tp cardboard with about 25 turns of magnet wire that I couple to signal generator and place near the radio, seems to work OK. I also do check and adjust accuracy of what my ancient signal generator spews forth, after it has warmed up, with a frequency counter. If you don't have one, very inexpensive little digital ones are available, and are pretty accurate.
