[Milsurplus] I-222-A CPX-1 Signal Gen.

[john p hutchins]

I ask the group -

Any one know what the specs are for this unit: Signal Generator I-222-A 
CPX-1
Frequency range?
If you have this manual:
TM 11-1082  Signal Generator I-222-A (15 July 1944); 42 pages, 30 illus. 
May contain the info I need?

Thanks
Hutch
