Yaesu has been founded by a Japanese radio amateur and started with the production of ham radio transmitters. After the ham band only receivers FRDX400 and FR-101, Yaesu entered the market 1977 with it's FRG-7. The so-called FRoG was a solid state triple conversion allwave receiver, using Wadley - Loop - technology and a preselector, it sonn became a very popular allround shortwave receiver and is still considered as an absolute classic.
After the succeeding FRG-700 with a digital frequency display, the FRG-7700 with it's PLL synthesizer circuitry, optional internal 12 station memories and the optional external antenna tuner, active antenna and VHF-converter was a very popular and successful set, too.
The good relationship between price and performance was later found in the FRG-8800 and the slightly smaller FRG-100. It is obvious, that the manufacturer has it's roots in the amateur radio business, the receiver configuration can adapted and Yaesu never followed the bad habits of coupling reception mode - IF filter bandwidth - tuning step automatically together, the choice is left to the listener.
