I think I remember, but cannot find that reference right now that M actually referred to the K ohm value until it was standardized. I am wondering if this set was under one of the old resistor coding systems? I see other resistors on the parts list using Meg designation but wonder if it was because of space limitation in the columns on the parts list. So my question is: Is M really megaohms or K ohms in this specific set? And is Meg the coding for Megaohms as they list them?

9M can't mean 9 megohms. That wouldn't make sense in an old radio. So, 9M = 9 kilohms (9000 ohms).

:I seem to be having trouble identifying resistor values in the set I am working on. AIRLINE 62-307. When they refer to a 9 M resistor in the parts list are they using an older color coding scheme? This set is at:

They used a "BED" system of color coding resistors, which meabt Body, End, Dot, where the first number was the body of the resistor, the second the color placed on the end, and the third the dot on the body of the resistor. The colors stood for the same numbers.

I'm not up on all of the Latin lingo, but I know a bit of Spanish, which comes from Latin. In Spanish mil means thousand, and million (the ll pronounced like a Y) means million. I wonder how they abreviate their schematics. Perhaps they use the English method?
T.
M is Roman for Thousand. From Roman Numerals.
http://www.roman-britain.org/numerals.htm
There is a symbol for Million in Roman Numerals as you'll see on the above page. But Meg from Greek was easier to write or type. But then the M and Meg got confusing so they went to Greek for both M and K.
On schematics where M is 1000, they spell out Meg for Million.
I hope that this helps.

:::Bob: M = thousands in Roman numerals. Later, K = thousands caught on. It has nothing to do with color coding, which hasn't changed that much.
