This is Icom's first product available in the U.S, but branded with the company's original name, Inoue.
Available in 2 watt (FDFM-2) or 10 watt versions (FDFM-2S).
The FDFM-2 evolved into the IC-2F.
Many ads for the FDFM-2(S) give the clear impression that it was made by Varitronics. Varitronics was an early U.S. importer/distributor (and re-seller) of radios built by Inoue (the company that later became Icom). In the early 1970s Varitronics sold units that were manufactured in Japan by Inoue — sometimes co-branded or shown as “Varitronics” in ads/catalogs — rather than being an independent manufacturer.
