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.

    just noticed on the veroboard layout that track needs to be cut after the oscillator transistor base termination.
    sorry for omission

    ps outputs as follows
    bc109b 120mw
