Hello to all.I have a old dentron gla-1000b.It has been mooded to use the gu7b(I think that is the tube).It runs abt 350-400 watts.I used it for field day a few years ago.Anyway I am thinking of converting it to 6 meters.Some thoughts on this?.I am thinking a plate coil of abt 3-4 turns..What else would be needed? 73 john
