The 74028 heterodyne frequency meter is the main part of the model LM-(*) crystal calibrated frequency indicating equipment, in the models LM-10 and higher, for use in the Naval radio service.

The 3 letter code is a manufacturer identification: CRR=Bendix Radio, CKB= Mission Bell Radio, and CBLC=Loral Electronics. There might be more manufacturers.

The LM-1 to LM-9 equipment used a similair frequency meter with a low range oscillator from 195-400 Khz.
