This is a Dynascan Cobra 139XLR with the addition of a Digi-Scan 400. In the late 1970s and early 1980s, this was considered the ultimate in CB frequency expansion capabilities. Sure, you could buy a Siltronix VFO, but now, you could digitally select the frequency of your choice! At the time, this Digi-Scan was cutting edge technology. It did not come cheap, however. The Digi-Scan unit sold for around $400. That’s in addition to the cost of the radio and conversion/modification expenses.
