[Boatanchors] National 1-10 Coil Range

[Joe Connor]

 Thanks, Rodger and Doug. That makes perfect sense.
When I got the set, the C coils were installed, so it looks like the prior owner was listening to the FM BCB the last time he used this set.

Joe,

  
 
You have to go by the curves in the manual which are listed in meters: http://bama.edebris.com/download/national/1-10/HRO-1-10.pdf

  
 
Here is a handy online calculator:  https://www.unitconverters.net/frequency-wavelength/wavelength-in-metres-to-megahertz.htm

  
 
It is a cool little set, I have one also.  Not really that practical these days but definitely historically interesting.

I need some help. I bought a National 1-10 today, complete with all six coil sets.
Can anyone tell me the frequency range of each coil set, A-F?
As always, thank you for your help.
