From the estate of a ham op
Addington Labs Model 200110001 Signal Source. Was marked UHF and 430 MHz on the box. We fired it up for a quick check and it showed signal at just shy of 423 MHz on the spec an. We didn't measure the level or make adjustments. It is -28VDC power. 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!
