I ahve some transmitter tuning charts, from what kind of radio i don't know but they are 6 3/4 by 10 7/8 in size. On one of them at the top right hand corner is typed Frame 2906.
Information columns are
Output Crystal Channel A B C D E F G H I J K L
Freq Freq and
MC KC Crystal
Position
1
2
3
4
5
6
7
8
9
10
Below the last row of information is the tuning instructions On one of the charts all the information (dial settings) are filled in for all 10 channels.
On another chart none of the above is present but current readings for the various meters istyped in. As an example, Dial B, tune for max DBLR grid current 15-18 ma.
Dial C. Tune for max 2nd trip grid current with DBLR Cathode current at dip value not exceeding --- Ma for tune pos and ----MA for "Operate" Grid current 18-20 ma.
More settings and readings for the rest of the dials. No indication of what transmitter this would be, Navy i'd bet because of the form number but otherwise maybe a VHF type?
Form number at the lower left corner is N.P. 11 2834
Sure like to find a righful home for these forms. Someone must know wht radio they go to and i'll sure be glad to donate them. Total of 9 forms of the same type number.
