emerson: Ch= BM; BM216 Scale with an error?

Since the upcoming of transistor radios - and before for tiny tube radios one could see inscruptions for the broadcast band like 6 to 16 or even 5 to 17 - just to have a minimum on information on the frequency (cycles) or wavelength (meters). Often you could even not tell if it is the frequency or the meters ...

If there was more space, then was printed for instance 5.4 to 16 like here or 54 to 160 with sometimes a hint like here "x 10KHz" or the other way around, 160 to 51 for KHz.

The latter is wrong because it is 10KHz or 10,000 cycles and not KHz or KILOCYCLES as written on the Emerson radio BM216. Interesting to see there that the meter scale is right.

To thank the Author because you find the post helpful or well done.
