A remarkable achievement. I doubt that many will want to put in the effort to repeat it! Few would have the patience for those hours (days!) of coil winding. I don't think there is much interest beyond this mailing list. In fact I reckon most of the LF group have moved onto the Yahoo group, there are probably less than a dozen people following these experiments (if my web logs are anything to go by). Historic perhaps, but we've picked an obscure corner of the hobby to play with! -- Paul Nicholson --
