I am not sure where some people get their information. Regency was not only around long enough to see production of synthesized scanners, they were the first company to produce one! This was the Touch 16....I have two and one original manual. The first electronic switching scanner was invented by Al Lovell at Electra Corporation (Bearcat). A friend of mine who is a retired engineer worked on this project with Al. The first VHF converter (from VHF) to a general broadcast radio was the "Little Tiger", also made at Electra.
