I have asked on the yaesu tuner list and the FT-897 list but as always I imagine the best informed Hams are right here on TowerTalk. May the Yaesu FC-40 tuner be used with rigs other than the FT-897? I hope to acquire a FT-897d soon but also have a TenTec 580 Delta. Any special interfaces needed? -- Thanks! & 73, doc kd4e bibleseven.com
