30m QRP transceiver from GJ7RWT

Andy GJ7RWT has sent me his schematic for a 30m QRP CW transceiver which has some similarity to the XBM80-2 and the transceiver from K4TWJ. He gets 150mW out and the receiver can copy signals down to around 10uV. He has made the circuit on strip board (veroboard) and the layout he used is attached.

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.
