[ARC5] BC-221 Not a Silly Question

[John Hutchins]

Johyn -
Per page 144 for BC-221-AK maintenance  section, refers to TM-300 PAGE 
21.  Looks like later on in the war we had extensive Depots so the some 
sections may have been paired down.

BC-221 M manual I got off the web in DjView format.  I noted document, 
Dated November 13 1942, 11 months into the War, Titled Preliminary 
Instructions for Frequency Meter Set SCR-211-M, had extensive details on 
how to calibrate the Xtal Osc. on Page 21.  I am sure this can be 
applied to the BC221-AK version under the proper conditions.

As you have indicated there may be individual manuals on each set for 
5th echelon service?
