You've got the newer version.. Mine is a '86 vintage 20MHz Kenwood from the same retail chain. It works but the gain and timebase controls are in dire need of replacement due to use and so are very touchy... Much more a 'just turn it on and then set and forget' device nowadays...

Been looking at a modern replacement via Ebay that will cost near half what I paid way back then for my old and tired Kenwood...
