I've heard of what's being described by Bob and Doug sweeping an input, logging and manually graphing the meter readings and response curve. I've heard of it being used by engineers in the tube era.
For either a very low resolution graph skipping large frequency swaths, a more simple system than a TV IF, or if the world comes to an end and all the few survivors have to work with for a reading is a simple meter I could see this being viable. But for a TV alignment it seems like as fun a task as trying to build a decent sized modern stone building using only the tools and methods of the ancient Egyptian pyramid builders from quarrying through construction...Sure you can do it, but the time a modern tool saves should more than pay for said tool.
