This set is apparently known as a CMS. The schematics in the lid of the wooden "painters case" are labled CMS-T and CMS-R. The frequency charts and the TX and RX bear the (serial?) number 96H. RX is regen with three triode connected 1T4's. TX is 2 6V6's in an MOPA arangement. Master oscillator may also be crystal controlled. Parts are clearly of late 30's or '40's US manufacture. No manufacturers name or military ID anywhere. |
