K4TWJ (the "One Transistor Marvel" man)

Yesterday I heard that Dave K4TWJ is in hospital having had a massive heart attack on New Year's Eve. His XYL Sandy, WB4OEE, reports that he is improving and getting stronger. Dave writes articles in several US magazines including CQ and his design for a very simple one transistor transceiver appears in the International QRP Collection book available from the RSGB.
