I just picked up a Yaesu FT857D to use on VHF/UHF/satellites, and HF until I find a stand alone HF rig. Is the 718 a significant improvement over the FT857D receiverwise? Or what would be a good used Icom HF rig to get for $500 or so? 73s John AA5JG (ex: W5TD, NE0P, N0EEN, KA0IFG) Confirmed 6M addict: 6M WAS #1275, 6m VUCC #1260
