Appears to have been a JA market unit, circa 1989, 144/430 MHz, 10W output, Type F3 (FM) modulation, Yen 79,800 (MSRP?), superceeded by the IC-2320M, circa 1990, as above but 25W output & Yen 85,800 -- all conditional on my reading of Japanese to English translations.
Probably only transmits 144-146 MHz & 430-440 MHz vs. Region 2's 144-148 MHz & 440-450 MHz. There's info on the web on it, but it's almost all in Japanese not English. Keep looking 'till you find a North American market radio.
usually has basic info and often a photo, but not the IC-2320.
