Hello (X)YLs and OMs ! I'm still trying to determine the model number and manufacturer of the 4 pin DC power supply connector which is used on the FT2000. If I'm informed well, the same connector is also used on the Yaesu FT950, FT450, FT480, the ICOM IC7000, IC7200, IC7400, IC7600 and Kenwood TS590. Thanks a lot ! Best 88 de Claude
