From the estate of a ham op
TRAK Microwave Signal Source. Model 5041-1087 for 130 MHz. We tested it for output only as shown. Since we didn't know the design voltage, we started at the low end and it came alive about +9 VDC. it could be designed for a higher voltage, we don't know. Sold AS-IS AS-FOUND for parts or repair with no return since we don't know your level of expertise on this stuff. Enjoy!
