[Milsurplus] Homebrewed BC-221 Cal Book

[Laura and Jim]

Recent discussion of these w/missing cal books jogged my memory. 

I couldn't get the BASIC/FORTRAN version to work either so I developed a little OCD..........

and created one for my '221-AK using a modern frequency generator and Excel.

Here was my procedure after 4 hour warm-up:

1 - set the generator at the check point frequencies
2 - read the dial number off the BC-221/LM in question
3 - assuming these run nearly linear between checkpoints, develop slope of line between check points for interpolation calculations
4 - plug in start/end values for each check point pair. 
5 - increment start value by 5kHz

The program does the rest.

Not dead-on, but it was close enough for my needs. 

I'll send a copy of the Excel file to anyone who would like one to play with.

If you win the Nobel Prize, hoist one to me, hihi!

Cheers!
